The Overview Effect

December 5, 2019 By Zola Zeester Leave a Comment

The iconic Earthrise photo was taken in 1968 by NASA astronaut William A. Anders during the Apollo 8 mission, the first manned spaceflight to orbit the Moon. Never before had a human observed the Earth rising, and Anders’ amazing, first-ever color photo of our stunningly beautiful planet emerging from a lunar horizon still takes your breath away.

“We came all this way to explore the Moon, and the most important thing is that we discovered the Earth.” — William A. Anders

To See The Earth As It Truly Is*

[su_quote cite=”Frank Borman “]It was very, very sobering to see this little blue marble in the middle of all that darkness. [/su_quote]

The awe-inspiring effect of seeing the whole Earth from the vantage of space (known as “Earth gazing”) is most often described as an overwhelming sense that Earth is an “interconnected whole with one destiny”. An understanding that’s key to our survival. Of course, we can’t see it and feel it firsthand (only 24 humans out of 7.3 billion world population have had the experience) until space travel becomes practical for the general public, but innovative technology continues to provide us with more and better information and visuals.

The short documentary Overview (from Planetary Collective) explores a cosmic worldview with reflections from “Earth gazing” astronauts and philosophers as well as beautiful space imagery. Watch and be inspired by the “unity and oneness of all life on Earth”.

Earthrise: Remembering Apollo 8. Launched on December 21, 1968, Apollo 8 became the first manned spacecraft to reach the Moon, orbit it and return, and its crew became the first humans to see and photograph the Earth emerging from behind the lunar horizon. Watch as the Griffith Lab All Space Considered team recalls the lead up, events and discoveries of this historic mission in celebration of its 50th anniversary.

*”To see the earth as it truly is, small and blue and beautiful in that eternal silence where it floats, is to see ourselves as riders on the earth together, brothers on that bright loveliness in the eternal cold — brothers who know now they are truly brothers.” Archibald MacLeish (1892 – 1982) American poet

Kīlauea

November 12, 2019 By Zola Zeester Leave a Comment

“During a volcanic eruption, we are reminded that our planet is an ever-changing environment whose basic processes are beyond human control. As much as we have altered the face of the Earth to suit our needs, we can only stand in awe before the power of an eruption.” — US National Park Service

Hawaiian Ridge - Emperor seamount chain consisting of islands, undersea mountains and volcanoes extends across the Pacific Ocean. — Hawaiian-Emperor seamount chain, NOAA and ESRI® Data & Maps (Public Domain)

The “Hawaiian – Emperor seamount chain” is a vast undersea mountain range interspersed with islands, underwater mountains (seamounts), atolls (ring shaped coral reefs encircling a lagoon), shallows, banks, reefs and more than 80 volcanoes, that extending across the Pacific Ocean for 3,728 miles (60,000 kilometers) from the Hawaiian islands to Alaska and Siberia. The chain has been forming during the last 70 to 80+ million years by volcano eruptions and movement of the ocean floor (the “Pacific Plate”) over a volcanic region known as the “Hawaii hotspot”. Closest to this hotspot is the Hawaiian archipelago (aka Windward islands) that includes eight main islands: Hawaii (aka ‘the Big Island’, the Island of Hawaii & Hawaii Island to distinguish it from the US state of Hawaii), Maui, Oahu, Kauai, Molokai, Lanai, Niihau, and Kahoolawe, as well as a number of small islands, atolls, and seamounts, that extend 1,500 miles (2,400 kilometers) from the Kure Atoll to the Big Island, the southernmost point of the Hawaiian – Emperor seamount chain.

The formation of the Big Island is the result of sequential and simultaneous eruptions of five ‘shield’ volcanoes (low profile, circular, slopping shield shaped volcanoes) over a period of about 300,000 – 600,000 years, and at 93 miles (150 km) across and a land area of 4,028 sq. miles (10,430 km²), it’s the largest of the Hawaiian islands and still growing because of the lava flow from currently active volcanoes, Mauna Loa and Kīlauea.

In accordance with beliefs and practices of the traditional Hawaiian religion, summits of the five Big Island volcanoes are revered by native Hawaiians as sacred mountains, and the powerful, passionate Fire Goddess, Pele, is believed to live within the Halema’uma’u crater located at the summit of Kīlauea. Pele’s domain, however, includes all volcanic activity on the Big Island, and she has the ability to cause lava to erupt from the ground at any time. She’s been a very busy goddess during the last four decades.

The Kīlauea Volcano

The name ‘Kīlauea’ is translated to ‘spewing’ or ‘much spreading’, referring to frequent lava flows originating from the volcano. The name is well-deserved as there have been 61 separate eruptions from Kīlauea since 1823, making it one of the most active volcanoes on planet Earth. Most of these eruptions have been relatively moderate and have occurred within one of its ‘rift zones’ with lava flows moving downslope. [A rift zone is an area of ruptures on the surface that allows lava to erupt and flow from the flank of a volcano instead of its summit.] However, fire goddess Pele does periodically create havoc with explosive and sometimes deadly eruptions that expel molten rock and gases across the landscape of the Big Island.

Kīlauea’s most recent major eruption (dating back to January 3. 1983) is the longest period of volcanic activity in its documented history with lava flowing almost continuously for 35 years from the volcanic cone, Puʻu ʻŌʻō (‘high point on the skyline’) located within Kīlauea’s East Rift Zone. [Volcanic cones like Pu‘u ‘Ō‘ō are formed by the ejected magma rocks piling up around a vent.] The catastrophic collapse of Pu‘u ‘Ō‘ō on April 30, 2018, resulted in the iconic eruption site and surrounding lava flow fields becoming without lava during the rest of 2018. The absence of surface activity for such a long period of time makes it unlikely that lava activity will resume within Pu‘u ‘Ō‘ō; therefore, scientists have determined the eruption has concluded. It’s important, however, to remember that Kīlauea remains an active volcano, and hazards have not changed as a new eruption can quickly cause dangerous conditions. For Kīlauea status updates, check out the Report from USGS – Hawaiian Volcano Observatory (daily updates and warnings).

In the video documentary 100 Days: 2018 Kilauea Eruption, photojournalist Andrew Richard Hara chronicles his emotional observations of the 2018 Kīlauea eruption.

Also, see lava flow from Kīlauea up-close in HD. Two short videos, Dawn of Fire and River of Fire, (filmed and produced by Tyler Hulett) capture flowing molten lava as it moves toward the Pacific Ocean from Puʻu ʻŌʻō during daylight and night. It’s an incredible sight to see.

Visiting Kīlauea

“A spectacle, sublime and even appalling, presented itself before us. We stopped and trembled. Astonishment and awe for some moments rendered us mute, and, like statues, we stood fixed to the spot, with our eyes riveted on the abyss below.” — William Ellis (1794 – 1872), describing his first sight of Kīlauea

The first western visitors to Kīlauea were two missionaries in 1823, William Ellis, an Englishman, and American, Asa Thurston, and after the building of hotels on its rim in the 1840’s, Kīlauea became a tourist attraction. Today, it’s protected within the Hawai’i Volcanoes National Park and visited by 2.6 million people annually. The park offers visitors dramatic volcanic landscapes of Kīlauea and Mauna Loa, archeological sites, historical places, and a look at rare flora, fauna and wildlife as well as hiking, biking, touring and camping. Popular stops are the Kilauea Visitor Center and the Thomas A. Jaggar Museum & observation deck.

Sol Invictus

November 5, 2019 By Zola Zeester Leave a Comment

Since the launch of the Solar Dynamics Observatory (SDO) in 2010, humans have had an unprecedented close-up view of the Sun, and the images captured are breathtaking, revealing a red-glowing Sun ablaze with flares, filaments and eruptions. The short video, SUN, by Michael König, is an edited time lapse sequence of SDO images obtained between the years 2011 and 2015. It will change forever how you see the Sun.

There are billions of stars like our Sun scattered throughout the Milky Way galaxy, and many are bigger and brighter. What makes the Sun uniquely superior (at least from the human perspective) is that it has made life on Earth possible, providing warmth and energy and holding the solar system together with its gravitational pull.

Just like all the other stars, the Sun is a big ball of gases. It has a radius of 432,168.6 miles/695,508 kilometers (1.3 million Earths would fill the Sun’s volume), with a surface (photosphere) temperature of about 10,000°F (5,500°C) [carbon such as diamonds and graphite will boil at that temperature]. Above the photosphere is the chromosphere and the corona, where it is even hotter (3.5million°F/2million°C) and features such as flares and sun spots appear.

The Sun will one day run out of energy and die as all stars eventually do, first swelling to a size large enough to engulf Mercury, Venus and perhaps Earth as well before collapsing and shrinking down to its burned-out core (becoming a ‘white dwarf’). Scientists have predicted the Sun has approximately 6.5 billion years remaining in its lifecycle. So, there’s still some time to enjoy life under the Sol Invictus before packing your bags and taking off to a new home planet.

TOTAL SOLAR ECLIPSE
August 21, 2017

A solar eclipse occurs when the Moon passes between Earth and the Sun, causing the Sun to be totally or partially obscured for a viewer on Earth. A total solar eclipse occurs when the Moon blocks all direct sunlight, turning day into darkness within a narrow path across the Earth’s surface (a partial solar eclipse appears in wider area alongside the path of the total eclipse).

Everyone in North America can experience the total solar eclipse on August 21, 2017 — 2017 Total Solar Eclipse Path, NASA

It was the first total solar eclipse to move across the entire US since 1918, and eclipse watchers were able to take in the ‘total’ experience on August 21, 2017 as it entered the US from Oregon (crossing between Lincoln City and Newport), and exited in South Carolina between Georgetown and Charleston.

If Stars Could Speak

November 5, 2019 By Zola Zeester Leave a Comment

Awake by Zach Rogers is a short video beautifully photographed and produced using a time-lapse process that results in mesmerizing views of star filled skies above stunning landscapes. It was a 3 year “passion project” involving the selection of 6,870 photos from a collection of 50,000.

“A philosopher once asked, ‘Are we human because we gaze at the stars, or do we gaze at them because we are human?’ Pointless, really….. Do the stars gaze back? Now, that’s a question.” — Neil Gaiman, Stardust (1999)

Experiencing a night sky teeming with glittering stars awakens curiosity, perspective and inspiration, and is a recreational activity enjoyed by amateur astronomers throughout the world. The opportunity to see such a sight, however, is getting more difficult as dark skies are vanishing from the glaring effects of light pollution. In fact, more than 99% of people living in North America and Europe see light polluted night skies rather than stars, and the Milky Way is hidden from more than 1/3 of the world’s population. The International Dark-Sky Association (“IDA”) works to protect night skies and ecosystems within parks and conservation areas around the world. Find dark skies for your best stargazing experience via the IDA locator map HERE, and look around for Telescopes and Stargazing Guide Book * to learn more and get started.

Crowning Cassini

November 1, 2019 By Zola Zeester Leave a Comment

Saturn is a giant planet (2nd largest in our Solar System) composed mainly of hydrogen and helium and visible from Earth without the aid of optical instruments as it shines a golden steady light in evening skies. Consequently, Saturn was known by prehistoric man, and became a major character of ancient mythologies.

The rings of Saturn, however, are not so easily viewed, and were not known to exist until Galileo Galilei (1564-1642) first saw them in 1610 using the newly developed refracting telescope. He thought the rings were actually two moons alongside Saturn. Forty-five years later, he was proven wrong when Christiaan Huygens (1629-1695) observed a “thin, flat ring” surrounding Saturn using a telescope he designed with greater magnification. In 1675 at the Paris Observatory, Giovanni Cassini (1625-1712) discovered a wide, dark gap between the rings of Saturn, known as the ‘Cassini Division’. As technology has increased visibility, nine continuous main rings and three discontinuous arcs have been observed within Saturn’s ring system.

Christiaan Huygens also discovered the first and largest of Saturn’s many moons, Titan, in 1655, while Giovanni Cassini was the first to observe four others, Iapetus (1671), Rhea (1672), Tethys and Bione (both in 1684). There are currently 62 known moons of Saturn, 53 confirmed and officially named and nine provisional moons as well as dozens to hundreds of ‘moonlets’ (small natural satellites orbiting a planet).

The Cassini Mission

An international mission to explore Saturn, its magnetosphere (region surrounding a planet that’s dominated by the planet’s magnetic field), rings and moons began more than 25 years ago, starting with seven years of development prior to the Cassini-Huygens spacecraft launch in 1997. The design of the unmanned spacecraft included a Saturn orbiter (Cassini) and a lander (Huygens) for Titan.

On December 25, 2004, Huygens separated from Cassini, and on January 14, 2005, successfully landed on Titan, while collecting and transmitting data to Earth using Cassini as a relay. It’s batteries died shortly after landing; therefore, Huygens now sits in silence on Titan’s surface.
[ESA Science: Huygens Top 10 Discoveries at Titan]

Cassini entered Saturn’s orbit on July 1, 2004, and photographs taken during the last 12+ years have led to significant discoveries. The 2012 NASA/Jet Propulsion Laboratory video, Cassini: 15 Years of Exploration, hits some of the highlights.

End of Mission: Cassini’s primary mission was completed in 2008 as it had made 74 orbits around Saturn. The mission, however, was extended to September 2010 for additional study, and extended a second time to 2017. It’s fuel supply running low, Cassini made a number of passes through the gap between Saturn and its inner ring before it was intentionally destroyed on September 15, 2017 by forcing a dive into Saturn’s atmosphere. The purpose of the deorbit was to mitigate the risk of Cassini later colliding with one of Saturn’s moons.

Super Star Sorcery

October 26, 2019 By Zola Zeester Leave a Comment

Deep space exploration and images captured via space telescope are nothing short of extraordinary as ever-improving technology enables scientists to reach farther toward distant planets and other galaxies. The wispy blue Witch Head Nebula (aka IC 2118) is just one example of many discoveries, but probably best represents the magic and mysteries of space and our fascination with the supernatural.

The Witch Head Nebula is a reflection nebula located in the Eridanus constellation. — NASA/Gary Stevens, prepared by Adrian Pingstone PD

Witch Head Nebula is located about 900 light years from Earth (FYI: 1 ly = 9+ trillion km/6 trillion m) within Eridanus (a large constellation appearing as a “river” in the southern hemisphere). “Nebula” is the name for an accumulation of dust, gases and other material that form into clouds within our galaxy and beyond. There are lots of them out there and several different types, and it’s believed Witch Head is an ancient “supernova remnant” nebula, meaning it was created by a massive star explosion. The wicked witch profile is created by the illumination of this cosmic cloud by Rigel, a nearby supergiant, blue-white star in the Orion constellation, that’s a couple hundred thousand times brighter than the Sun.

“When you make the finding yourself – even if you’re the last person on Earth to see the light – you’ll never forget it.” — Carl Sagan (1934 – 1996)

Vampire Bats

October 24, 2019 By Zola Zeester 2 Comments

Bats are the second largest group of mammals in the world (rodents are the largest) including more than 1,330 different species. They can be found on every continent (except frigid Antartica), and are the only mammals capable of true and sustained flight. Habitats and diets of bats are varied, but most are nocturnal and bugs, both flying and ground dwelling, are their primary food source, each bat typically consuming several hundred insects in a few hours and a third of its body weight during one night of hunting. Only three bat species consume animal blood exclusively: the common vampire bat (Desmodus rotundas) go for livestock, while the hairy-legged (Diphylla ecaudata) and white-winged (Diaemus youngi) vampire bats prefer birds.

It’s chilling to think about this bat sinking its teeth into flesh on a dark night, and visions from Dracula movies come quickly to mind. So, first impression—not much to love. However, studies of vampire bats have revealed their surprisingly amiable traits and extraordinary intellect.

Vampire Bats Don’t Suck, They Lick

First, we must address the most disturbing and frightening vampire bat behavior — they drink blood. The common vampire bat will feed on any warm blooded animal, but it doesn’t bite, suck and slurp out blood as shown in horror films. Rather, the process involves a painless bite with razor sharp teeth while the target is sleeping and lapping up about a tablespoon of blood. Rarely does a vampire bat feed on human blood, and the risk of rabies infection is minimal; however, incidents have been documented. Admittedly, this information is not altogether comforting. Let’s move on.

They’re Social, Sharing, and Caring

All three vampire bat species can be found in the arid to humid, tropical and subtropical areas of the Americas, from Mexico to Brazil, Chile, Uruguay, Argentina and the island of Trinidad. They live in small and large colonies located in totally dark places, such as caves, old wells, tree hollows and buildings, and the relationships within the colonies are cooperative and caring. For example, vampire bats maintain social contact with vocal exchanges, and form strong bonds by engaging in social grooming and food sharing. They have been observed within a colony feeding a hungry bat in danger of starving by regurgitating and sharing a small amount of blood, and it’s believed the benevolence is later reciprocated by the grateful bat. Signs of true friendship.

They are Scary Smart

They need to be clever to survive in this hostile world, and have proven to be more than capable. Researchers are just beginning to understand the aptitude of these intelligent animals as lab experiments seem to indicate vampire bats can be trained to perform tasks and will retain the learning for a significant period of time.

Watch vampire bats in action, and learn more about their social behaviors in this short video (3 minutes) from Gerald Carter, a biologist at the Smithsonian Tropical Research Institute in Panama.

BAT HOUSES: Bat species around the world are experiencing habitat loss. Placing an artificial roost in your backyard gives them a safe and comfortable place to live and is a great way to help them survive.

Birds of America

September 19, 2019 By Zola Zeester 1 Comment

Some time around 1820, French-American artist and naturalist, John James Audubon (1785-1851) started work on a personal project to paint every bird species located in North America, using unique methods and materials as well as extensive field observations. It was a tremendously challenging and costly endeavor, and many doubted Audubon’s ability to pull it off. In fact, the idea would seem a little wild & crazy even today with 21st century technology. But, Audubon was no ordinary guy. He was also totally committed to finding and illustrating every bird in North America for publication, working more than 15 years toward his goal and raising cash by teaching, selling art works, taking oil painting commissions, hunting and selling animal skins, and conducting exhibitions and demonstrations.

How to view and download John Audubon's extraordinarily beautiful illustrations in The Birds of America. — Common American Swan (The Birds of America, plate 411) is courtesy of the National Audubon Society, John James Audubon Center and Montgomery County Audubon Collection

The result of Audubon’s work is The Birds of America, first published in England as a series of 87 sets of prints between the years 1827 and 1838. Now considered to be the greatest study of birds in history as well as one of the greatest examples of book art, the original publication included 435 hand-colored, life-sized prints of North American birds on handmade paper that were produced from copperplate etchings and engravings with water-coloring applied by assembly-line colorists. An accompanying text (‘Ornithological Biography’) was written by Audubon and the Scottish ornithologist William MacGillvray and published separately in five volumes (1831-1839).

The cost of printing the first edition of The Birds of America was an amount equivalent to more than $2 million US dollars in today’s money. Audubon financed the massive print project with pre-paid subscriptions, but only the wealthy could afford the subscription price which limited the publication to no more than 200 complete sets. Consequently, more affordable editions were later produced using lithography and published during the mid-19^th century.

“The Birds of America’ will then raise in value as much as they are now depreciated by certain fools and envious persons.” — John James Audubon

Almost two centuries later, Audubon’s bird art is still captivating and revered among birders and art collectors, and his influence on ornithology and natural history has been widespread and enduring as The Birds of America and Ornithological Biography significantly contributed to the understanding of bird anatomy and behavior. Watching the short video, ‘Audubon’s Birds of America’ from the Lost Birds Project, you’ll get a sense of the massive beauty of these works of art as David W. Carson, curator of the History of Science Collection at Cornell University, conducts a private viewing of The Birds of America.

Six of the birds illustrated by John Audubon in The Birds of America are now extinct, and many more are endangered. Also — According to a recent study, North America has lost more than a quarter of its entire bird population during the past 50 years.

Be sure to check it out, and let John Audubon inspire your own creative work.

Audubon’s personal copy of The Birds of America is held within the Stark Museum of Art Rare Books & Manuscripts Collections in Orange, Texas. An original, complete series is on public display (one page is turned each week) in the Audubon Room of the Harlan Hatcher Graduate Library at the University of Michigan, Ann Arbor. It was purchased by the university in 1839 for the astonishing price of $970 (equivalent to approximately $80,000 today). Undoubtedly, a wise investment. In December 2010, a complete first edition from a private collection was sold at a Sotheby’s auction in London for US$ 11.5 million (a record breaking auction price).

Other permanent public display locations: Trinity College (Watkinson Library) in Hartford, Connecticut; University of Pittsburg (Hillman Library); Liverpool Central Library; Woodstock Inn in Woodstock, Vermont; and the Academy of Natural Sciences of Drexel University (Ewell Sale Stewart Library) in Philadelphia, Pennsylvania. Look around– there are surely more opportunities for viewing a first edition as there are currently 107 held by institutions, and many periodically offer special exhibits.

Audubon was the first, but there’s a new illustration of birds to get excited about! The Wall of Birds* tells the remarkable story of artist Jane Kim’s 2,500 square-foot mural celebrating the diversity and evolution of birds at The Cornell Lab of Ornithology. It took her 2 1/2 years to create the one-of-a-kind, life-size mural showcasing all 243 modern families of birds, and the book “is a visual feast, essential for those who love art, birds, and our natural world”.

Among The Trees

July 12, 2019 By Zola Zeester 4 Comments

“No more walks in the wood;
This is the aftermath
Of afternoons in the clover
Fields where we once made love
Then wandered home together
Where the trees arched above,
Where we made our own weather
When branches were the sky.
Now they are gone for good,
And you, for ill, and I
Am only a passer-by.”
— John Hollander, An Old-Fashioned Song

The Life and Loves of a Tree

We start loving trees as children because they are so much fun to climb and offer endless playtime adventures and hiding-out opportunities. As we get older, explore and learn more about trees, we find more to love and cherish.

Trees do many good things for the world — like cleaning the air, providing oxygen, and protecting us against a changing climate (to name just a few), and trees have incredible healing and restorative powers along with an ability to spark creative and spiritual inspiration. Just a short walk in the woods can lift your spirits. And, take a look around along the way. You may be surprised at what’s really going on among the trees.

A forest is actually a lot like a community of social beings. Yes, that’s right — trees in the forest are social, sharing, caring and also smart, having evolved to live in cooperative, interdependent relationships through communication and collective intelligence. And, all this extraordinary interaction among trees is happening underground, just inches below the surface.

Suzanne Simard, a professor of forest ecology at the University of British Columbia’s Department of Forest and Conservation Sciences in Vancouver, studies the below-ground fungal networks that connect trees and enable their underground “inter-tree” communication and interaction. In her TED presentation How Trees Talk To Each Other, Suzanne describes her field research (which included some tense moments with a bear) and the exciting discoveries during 30 years of study.

Peter Wohlleben’s international best-seller The Hidden Life of Trees (2015) fascinated readers to the many wonders of the forest. In a new, illustrated edition, beautiful images provide the perfect complement to the original book, with striking close-ups of bark and seeds, panoramas of vast expanses of green, and a unique look at what is believed to be the oldest tree on the planet.

FOREST THERAPY
Go To The Woods – Breathe Deeply – Be At Peace

In Japan, shinrin-yoku (forest bathing), is the practice of spending time within a forest to benefit from its therapeutic powers as well as to enjoy being surrounded by nature. Introduced in the early 1980’s as a Japanese national health program, it has become a popular healing practice throughout Japan and around the world.

Forest bathing activities may include relaxation techniques such as mindful meditation, yogic breathing (yoga deep breathing exercise) and aromatherapy as well as walking or simply standing in a forest absorbing it all through the five senses (sight, touch, smell, sound and taste). For the best experience, participants are encouraged to select a safe, secure forest and relaxation methods that best fit their needs and preferences.

Technical Recreational Tree-Climbing, a style of tree climbing requiring special equipment and techniques, continues to grow in popularity as an enlightening outdoor experience with therapeutic benefits as climbers ascend into the crowns of tall trees and canopies of forests. Basic training is essential to learning how to use the ropes, saddles, and techniques safe for both the climber and tree.

Once a year, Tim Kovar, an adventurous arborist and tree climbing instructor, takes a few people on a climb up one of the tallest trees in the world — an 850 year old California redwood called the Grandfather. It’s a summit Tim says less people have attempted than Mt. Everest.

Go Tree Climbing – The Global Organization of Tree Climbers provides information on training, climbing programs, and safety. Tree Climbers Rendezvous 2018 is a tree climbing event open to all levels of experience, scheduled to be held in Costa Rican Cloud Forest August 24-28.
Tree Climbers International – promotes tree climbing as a safe recreational activity for people of all ages, and offers recreational tree climbing courses from basic to advanced.

The California Brown Pelican

July 4, 2019 By Zola Zeester 2 Comments

Brown pelicans (Pelecanus occidentalis) can be found on both coasts of the Americas and are quite common along the coast of California, but it is a very unique pelican and its survival was at one time threatened.

A close-up photo of California Brown Pelican in flight — Frank Schulenburg CC BY-SA 4.0

While it’s a large bird, the brown pelican is the smallest of the eight species of pelican, and one of only three found in the Western Hemisphere. It’s also one of only two pelican species that feeds by diving into the water—a spectacular sight to see as it power-dives, bill-first, submerging underwater for a few moments before surfacing and swallowing its catch. Amazingly, they can spot a fish up to 60-70 feet above the surface of the water, and that height makes for some high diving and big splash-down.

Brown pelicans are also social and gregarious birds, living in flocks of both sexes and nesting in colonies on offshore islands. They are extraordinarily buoyant in the water as well as beautifully graceful in flight, flying in single file or “V” formation often low over the surface of the water.

Watching the skillful performance of brown pelicans is some of the best entertainment on the beach!

The brown pelican is protected by the Migratory Bird Treaty Act of 1918. In the early 1970’s, scientists discovered pesticides threatened the brown pelican by causing its eggshells to be too thin to support an embryo, which led to its listing under the Endangered Species Act, a ban on the use of the pesticide DDT in the United States, and curtailed, controlled the use of toxic insecticide. As a result of those protective government actions and other conservation efforts, the brown pelican made an eventual recovery. In a 2008 US Fish & Wildlife report, the brown pelican population in southern California was estimated at more than 11,000 breeding pairs, and it was officially removed from the endangered and threatened species list in 2009.

It’s a happy story of a great recovery and an example of how wildlife conservation efforts can help save endangered species, but brown pelicans still need some protection. There’s concern they are highly susceptible to climate change and destructive human activity, and the only breeding colonies in the western US are located within Channel Islands National Park on the West Anacapa and Santa Barbara islands. Consequently, preservation of this vital habitat along with continued monitoring are critical to the health and survival of the California Brown Pelican.

The Brown Pelican Survey project is a biannual citizen science-based survey organized and initiated in 2016 with the joint efforts of the US Fish & Wildlife Service, Cornell Lab of Ornithology (eBird), state agencies, Conservacion de Islas and the National Audubon Society in order to better understand the abundance and distribution of Brown Pelicans in California, Oregon, and Washington and track shifts in population. To see the May and October 2016 survey results, and for information on how you can participate in the survey, click/tap ⇒ HERE A total of 1,976 brown pelicans were counted across 18 sites along the Oregon coast in the fall of 2017 (reported by the Audubon Society of Portland ⇒ The Oregon Fall 2017 Survey Results)
