Guest post: Keeping watch over Brown Pelicans

Banded Brown Pelican Coming Down

Anna WeinsteinBy Anna Weinstein, Audubon California

The Brown Pelican is California’s iconic coastal bird and one of the great success stories of the Endangered Species Act. While pelicans have dramatically recovered in the last 30 years, they have since suffered unprecedented breeding failures and starvation events in California and Oregon, likely due to poor availability of prey. Audubon California is leading a set of concerned groups urging the Fish and Wildlife Service to complete key tasks required under the Endangered Species Act in order to secure the future of these beloved birds.

Globally, there are six subspecies of Brown Pelican. Most California Brown Pelicans breed in the Gulf of California (MX), and the rest in Southern California, mostly at the Channel Islands. In 2009, three subspecies including the California Brown Pelican were triumphantly removed from the Endangered Species List — a great success story populated with conservation heroes who worked to remove harmful chemicals from the pelicans’ environment and protect breeding islands.

Also in 2009, the Service issued a draft plan for monitoring pelicans following delisting. These “post-delisting monitoring plans” (PDM’s) are required by the Endangered Species Act in order to “monitor effectively for not less than five years” the status of a species following delisting. In the words of the Service, “the intent of this monitoring is to determine whether the species should be proposed for relisting, or kept off the list because it remains neither threatened or endangered.”

However, the Service never finalized or implemented the draft plan and no systematic monitoring has taken place, which undermines protection of pelicans in the Gulf of Mexico, the Gulf of California and the west coast. In the meantime, Brown Pelicans in California and Oregon have been showing signs of stress. At the U.S. Channel Islands, the most important U.S. breeding colony for this subspecies, biologists have noticed a decline in nest success starting in 2010, culminating in near-total nest failures in 2012 and 2013. These failures have been attributed to a lack of prey in proximity to the islands.

Additionally, unusual mortality events of Brown Pelicans in Oregon and California in 2009-2012 have been attributed to starvation. Many Audubon chapter members and leaders, including Dave Weeshoff, President of the San Fernando Valley Audubon Society and a volunteer with International Bird Rescue, have observed first-hand the unusual number of starving and disoriented pelicans, especially in Southern California.

Scientific studies have shown that breeding pelicans in California and in the Gulf of Mexico require anchovies and sardines to feed their young. In Peli IMG_0221-Mrecent years, both sardines and anchovies have been scarce or absent from this region due to a variety of factors including overfishing, climate change, and underlying natural variability. The Service is obligated to work with fisheries managers to ensure that sufficient prey is available to breeding and non-breeding pelicans. Right now, with no plan in place to guide monitoring and coordination, these essential activities are not taking place.

Audubon California and the Center for Biological Diversity submitted comments calling for the Service to act on its obligation to Brown Pelicans by finalizing a post delisting monitoring plan as required by the Endangered Species Act, and undertaking critical steps to better understand and track breeding success of Brown Pelicans at the U.S. Channel Islands, among other things. The Pacific Seabird Group, the scientific body for Pacific seabirds, also weighed in with similar concerns. The Service has responded by acknowledging the need to finalize the PDM and undertake focused monitoring and conservation activities for California Brown Pelicans. We will keep you updated as we work with the Service to reach these important objectives.

Anna Weinstein is a conservation biologist with over 15 years’ experience in policy analysis and advocacy, ecology, strategic planning and program development. In 1996 she co-founded Island Conservation, and later worked as a biologist at the San Francisco Estuary Institute, and as a program officer at the National Fish and Wildlife Foundation. In 2008 she joined Audubon California to lead the seabird and marine program, focused on protecting seabirds and their habitats, and raising public awareness about the west coast’s seabirds and marine environment.

• An abundant anchovy population — the reasons for which are currently unclear — provides for magnificent feeding frenzies of whales, sea lions and seabirds in California’s Monterey Bay. Via Audublog:

Nobody knows why anchovy are abundant here and scarce in other areas. This small, energy-rich fish can fairly be described as the single most important prey species for seabirds in Baja, California and Oregon due to its small size and nearshore distribution. Yet this essential prey item is facing new threats. While information on anchovy stock status is scarce, the little information that does exist suggest stocks have declined on the west coast over the past 20 years.

Fishing pressure is currently low, but is likely to increase due to the collapse of sardine over the past decade. Management attention and standards fall far short of what is needed to meet federal requirements for any actively fished species, let alone an essential prey item. [Audublog]

Patient of the week: Eared Grebe

This Eared Grebe (Podiceps nigricollis) was found beached in Monterey, CA and was transferred to us from a partner wildlife organization. We had this bird on our live webcam, The BirdCam Project, for several days, where it recently showed off its flight prowess and eagerness to escape! Here, the bird is released in the San Pablo Bay by one of our intrepid volunteers.

Meanwhile, our Los Angeles center is also caring for Eared Grebes. Here’s a recent photo from the L.A. center by Bill Steinkamp.

An all-too-common seabird menace: fishing gear injuries

IMG_3048According to last year’s data, about 22% of Brown Pelicans cared for by International Bird Rescue’s rehabilitation staff had confirmed injuries resulting from fishing gear, such as hooks and monofilament line, which can cause fatal constriction wounds.

And in 2013, we’ve seen a consistently high number of such injuries.

This Brown Pelican was found on November 12 at Dockweiler Beach in Los Angeles and rescued by Marine Animal Rescue. Upon intake at our Los Angeles center in the San Pedro neighborhood, we removed multiple hooks off this bird, some severely embedded.

International Bird Rescue rehabilitation technician Kelly Berry reports that the pelican was emaciated and dehydrated, but has since gained over 300 grams and is living in an outside enclosure. The wounds caused by the hooks are receiving treatment on a daily basis.

For more reading on fishing gear pollution and what we can do to limit this nuisance from the marine environment, we heartily recommend SeaDoc Society’s Lost Fishing Gear Recovery Project website.

Why do we show these images? After reading a recent post on fishing tackle injuries among seabirds, I realized that it may not be evident to everyone why we post these images and share these birds’ stories on our blog. It’s because fishing tackle and pollutants are daily obstacles for these animals, and we want everyone to know this. The real rub is that ALL of these problems can be fixed with just a little effort. Simply picking up discarded fishing line and tackle wherever you see it on a beach or pier, cutting it into small pieces and disposing of it makes a big difference. Many of these birds become entangled and injured by discarded fishing line and tackle that we walk by every day. — Jay Holcomb

Currently recovering in a diving bird pool alongside Common Murres and Eared Grebes is this small Horned Grebe (Podiceps auritus), shown here in its winter plumage. During breeding season, this small grebe sports red-and-black plumage as well as two yellow “horns” of feather patches from its eyes to the top of its head.

International Bird Rescue rehabilitation technician Isabel Luevano reports that this Horned Grebe was admitted to our San Francisco Bay center after it was found on a house roof (certainly not a location these birds are typically found) in nearby Santa Rosa. The bird has old eye injuries but has been doing well in the pool, eating its fair share of fish.

Our patient of the week is … a rhinoceros?

Auklet, Rhinoceros IMG_3081-L

Well, not quite. But the Rhinoceros Auklet gets its name for a reason.

Residents of the North Pacific, Rhinoceros Auklets (Cerorhinca monocerata) are also known as “Unicorn Puffins” for the small horn extension on their beaks, present in both males and females during breeding season (click here for a photo of this species during breeding). Like many seabirds, they are threatened by oil seeps and spills, including natural seepage off the Southern California coast. Unable to waterproof themselves, oiled birds often end up on popular public beaches.

That’s what happened to this Rhinoceros Auklet. We received the bird from a partner wildlife group after it was found oiled at Malibu’sAucklet, Rhinoceros IMG_2022-M famous Zuma Beach. After the auklet’s condition was stabilized, our Los Angeles center team washed a significant amount of oil off the bird. Without this process, oiled seabirds are unable to survive the cold temperatures of their ocean home.

This is just one of hundreds of oiled birds we care for every year — whether in California or beyond, including the Alberta tar sands, where an International Bird Rescue response team has spent months this year caring for animals affected by a bitumen release in a remote area.

Though this auklet may not know it (he’s far more concerned with the fish delivered to his pool during recovery), it’s your support that makes this work possible. Thank you!

Albatross

• Scientists studying albatrosses find that these magnificent seabirds have incredibly sophisticated flight patterns, which harness wind energy to propel them far more efficiently than their 11-foot wingspan could muster through flapping.

Via National Geographic:

A team of scientists from the Technische Universitat Munchen in Munich, Germany, used aerospace engineering to reveal the birds’ unique flight patterns—a physical feat that has puzzled academics for years. By attaching GPS trackers to 20 wandering albatrosses (Diomedea exulans) in the wild, the researchers were able to study data from 16 of the birds as they left and returned to the Kerguelen Archipelago (map) in the Indian Ocean.

Albatrosses yo-yo up and down in the sky, taking advantage of momentum generated on their downhill glides in order to climb back up against the wind. These constant up and down changes in altitude keep the birds aloft without requiring much effort.

The research article, “Experimental verification of dynamic soaring in albatrosses,” is published in the current issue of The Journal of Experimental Biology. [National Geographic]

“Gannets are long lived seabirds and there is still much to learn about their life away from the breeding colony,” said the University of Exeter’s Dr. Stephen Votier. “The application of technology to study the private lives of gannets has been influential to our research in the short-term, but the goal is to continue this work in the long-term to help provide a sustainable future for gannets and other marine life.” (Photo by Yeray Seminario.)

• Examining the increasingly early migratory patterns of the Black-tailed Godwit, scientists warn of climate change’s effects on bird migration. “We have known that birds are migrating earlier and earlier each year – particularly those that migrate over shorter distances. But the reason why has puzzled bird experts for years. It’s a particularly important question because the species which are not migrating earlier are declining in numbers,” Lead researcher Dr. Jenny Gill from the University of East Anglia’s school of Biological Sciences said.

Burrowing Owl, banded in Bay Area, spotted in Idaho

As a Master Bander since 1979, I’ve banded a lot of birds — most of them are the aquatic birds that we rehabilitate at our centers in Los Angeles and the San Francisco Bay. But I also support the local rehabbers when I can by banding birds that they are interested in, and many are raptors. As we all know, Lindsay Wildlife Museum in Walnut Creek, CA rehabilitates many animals and has a thriving raptor rehab program. I give them bands for some of the raptors that they release.

One of these raptors is a female Burrowing Owl assumed to be hit by a car in Berkeley, CA that came into care at Lindsay on Nov. 8, 2012 — one year ago today. The bird had various bruises and swelling, and radiographs confirmed a simple, mid-diaphyseal fracture of the left humerus. The fracture was pinned and wrapped, and the bird treated for over a month.

This owl survived her ordeal and made a good recovery. She was released at Cesar Chavez Park, in the Berkeley Marina area, on Dec. 27, 2012 with band number 0614-37468.

Last week, I received a band encounter from the Bird Banding Lab. On June 17, 2013, this bird was discovered alive and healthy by Jamie Groves, a graduate student of raptor biology at Boise State University who is studying Burrowing Owls near Kuna, Idaho, about 500 miles away from the release site. The bird still has her original band on, but Jamie added three color bands to easily identify the owl without having to catch her. Her color bands are: Right Leg: Mauve/Yellow and Left Leg: White/Aluminum Band.

More via Jamie Groves:

I banded this female, as well as her mate and their 7 nestlings (about 4 weeks old at banding). She was nesting in one of the artificial burrows that had been placed in the area some time ago. The nestlings were in really good shape, and from what I recall/see in my notes the female was in great shape as well. The few band-returns we have gotten back are from California, so it seems at least some of our owls like to go to there for the winter.

A big thanks to our friends at the Lindsay Wildlife Museum for their continued compassionate and professional care of our wildlife. And thanks to Jamie for reporting this owl to the banding lab. Much appreciated! —Jay Holcomb

Victim of a likely cat attack, a Black Rail is released

Black Rail 13-2457 at SF Bay Center banded for release on 10/31/13

Last week’s “Patient of the Week” on Facebook garnered a lot of attention from our fans: a Black Rail brought to us with a leg fracture and other injuries consistent with a likely domestic cat attack.

After a successful rehabilitation at our San Francisco Bay center, the bird was banded by Laurie Hall, a PhD student in the University of California, Berkeley’s Beissinger Lab and researcher with the Black Rail Project.

An elusive bird that hides in thick marsh vegetation, the Black Rail is listed as a near-threatened species (and formally listed as a threatened species by the State of California).

The rail’s wetland habitat, the International Union for Conservation of Nature (IUCN) notes, “is threatened by pollution, drought, wildfires, groundwater removal, changing water levels, grazing and agricultural expansion.”

Update on Elegant Tern cruelty case

Release day for Elegant Tern 13-2408 at SF Bay Center
Elegant Tern photos by Cheryl ReynoldsELTE

The Elegant Tern brought to International Bird Rescue’s San Francisco Bay center last month with a gunshot wound is now flying well and on track for release, our staff reports.

“We are amazed that this bird has recovered so well after sustaining such a traumatic injury to its wing,” says Isabel Luevano, an International Bird Rescue rehabilitation technician.

“During the course of this tern’s care, we did notice that the bird was having waterproofing issues, which correlate with the bird’s entry wound at its shoulder. After two quick washes, we believe the bird is getting closer to release, and appears to be regaining its waterproofing back quickly,” Luevano says.

Anyone with information on the perpetrator or perpetrators behind this animal cruelty case should call U.S. Fish and Wildlife Law Enforcement Offices in Burlingame, Calif. at (650) 876-9078. Elegant Terns are protected under the Migratory Bird Treaty Act.

• Plans to create the world’s largest marine sanctuary in Antarctica’s Ross Sea failed for a third time Friday over the objections of several nations with fishing interests in the region.

Proposed by the US and New Zealand, the marine reserve, which at 500,000 square miles would be about the size of Peru, was scuttled after Russia and the Ukraine ran down the clock during a 10-day summit in Hobart, Australia.

Adélie Penguins and Weddell Seals are just some of the amazing animal species that call the Ross Sea home.

“This is a bad day for Antarctica and for the world’s oceans that desperately need protection,” Andrea Kavanagh, director of Pew’s Southern Ocean sanctuaries project, told the Associated Press.

Kavanagh said while she doesn’t believe the plan is dead in the water, it’s unclear how the proposal could ultimately pass. The Commission for the Conservation of Antarctic Marine Living Resources is scheduled to meet again in October 2014. [AP via Huffington Post]
