Please Do Not Disturb!

Last week Kyra blogged about our trip to Ventura to try to recapture Pelican N-12, one of the control birds from the Refugio pelican post-release study. While the satellite telemetry aspects of the project have provided a huge amount of information on these birds, the companion efforts by OWCN and International Bird Rescue to get the public to report sightings of pelicans with green or blue leg bands has also been quite successful.

In some areas like Half Moon Bay it has almost become a sport, with individuals and bird- and whale- watching boats constantly on the lookout and trying to get close for a clear photo of the band number. We greatly appreciate everyone who has reported birds and made their contribution to our study, but we also want to remind everyone that getting too close can be harmful not just to the animal you are focusing on but also others nearby. In some cases, like nesting plovers or terns, there are obvious signs to help you avoid disturbing birds.

It may seem like pelicans have an easy life, just sitting on the pier or breakwater all day sunning themselves. Some might even think that getting them to fly a bit is good exercise. But like many wild animals, a pelican’s ability to find food versus their energy expenditures are often very finely balanced. As you can imagine, with a bird as large as a pelican, getting up into the air can take a fair bit of effort. If that effort results in a new fish in the belly or avoiding being injured or killed, I think we would all agree it was worth it. But each time there is an energy cost to each bird. When people, dogs, boats, or anything unfamiliar gets too close, birds will try to move farther away, just like we do when someone we don’t know or don’t like gets right up in our face. And when they are resting and hanging out together in large groups like on a beach or a breakwater, they may fly without a direct threat but just because other birds do.

Even if they don’t fly, their heightened vigilance may keep them from normal rest or preening activities.

A 1997 study “Buffer zone distances to protect foraging and loafing waterbirds from human disturbance in Florida” found that brown pelicans disturbed by a walking human flushed at just under 30 meters, and recommended a buffer of 100 meters for approach on foot. The recommendation for motor boats was 120 meters.

While in some situations it is possible to get closer to wild birds without disturbing them, especially with special techniques or equipment, in most situations it is best to give them plenty of space. Use binoculars, spotting scopes and telephoto lenses to record and report band numbers. As Hippocrates wrote “First Do No Harm”.

And thanks again for keeping an eye out for colored bands.

Refugio Pelican Update

We wanted to give everyone an update on the post-release pelican study from the Refugio spill, now almost one year ago. You may recall that 12 oiled pelicans and 8 control pelicans were outfitted with satellite tags so we could compare their movements and survival. In addition, all oiled pelicans that were released (not just the satellite tagged pelicans) got a green color band.  Please report all pelicans with green bands to us here if you see them. While you are out looking for pelicans, if you do happen to see any with blue bands, please report those birds to International Bird Rescue.  Even though we have a few control birds from this study that are sporting blue bands, most of the pelicans out there that have blue bands were rehabilitated by International Bird Rescue, and getting reports on where these birds are is extremely valuable.

Currently we have about 6 or 7 birds still transmitting. Two birds, one control and one oiled bird, have made some trips to Anacapa Island as if they were thinking about breeding, but they haven’t been there lately, so it’s unlikely that they are breeding.

A couple of control birds are hanging out in San Diego, and one of the rehabilitated birds is at a large lake in Baja California. Two other rehabilitated birds are in Baja; one is traveling north in the Gulf of California, and the other is in the central part of the Gulf of California. This last bird is a challenge . . . his satellite tag has stopped transmitting for extended periods of time, and then suddenly starts transmitting again right about the time we’ve decided the bird (or the tag) is dead. I’m going to give him the benefit of the doubt for as long as possible!

This May 7th, Audubon California sponsored a Brown Pelican Birding Blitz, where members of the public were encouraged to go find and report pelicans (AND maybe see some color-banded birds!). We are waiting to hear if anyone saw our green-banded birds! More information about the Blitz can be found here.

Here’s a map of the pelicans from the past month. If you look carefully around Los Angeles, you can see a bit of yellow peeking through — those dots all got covered by the bird in red. And near San Diego, you can see some blue dots . . . . that’s our bird with the satellite tag that seems lazy.

Destruction Isn’t Always Black and Slimy

During the Refugio Incident oil spill, I had the honor of spending time at the field staging area with some of our field responders. These folks spent their 12-hour workdays trekking up and down beaches, searching for and responding to reports of oiled wildlife.

But even when they didn’t find oiled wildlife on their outings, they never returned empty-handed. Instead, they brought back handfuls of trash and litter, everything from plastic bags and bottle caps to fishing line and wire.

At the time, our staging area was located at a closed campground near a protected beach – protected because of the endangered and threatened species that could be found there, including a least tern colony and nesting snowy plovers. I’d estimate hundreds of species called that protected bit of beach home – there’s always far more wildlife than you see, and we encountered mallards, ruddy ducks, scoters, stilts, avocets, horned grebes, pelicans, gulls, harbor seals, sea lions, and… well, you get the idea.

Twice a day, we would walk that beach, searching for oiled animals and picking up trash. We never left empty-handed.

This isn’t unusual, and it isn’t good. As icky as we find litter like this (and it does have negative effects on the economy and human health), it’s downright devastating to wildlife. Fishing line causes terrible entanglement issues, animals can get stuck trying to get the last smidge of food out of a poorly-shaped yogurt container, and bits of plastic and foil are mistaken as food and ingested by many species. These things can and do result in injury and often death.

Entanglement in particular causes severe damage that does not always respond to treatment, though there are plenty of uplifting stories as well.

We like to think that litter like this comes from careless people who can’t be bothered to find a trash can, and I’m sure some of it does. But the truth is litter comes from all sorts of places – many of which you’d never think of.

Balloons for example – how many times have you seen an escaped balloon floating away from a kid at a fair, and thought about the danger it poses to wildlife? It seems pretty innocent, but once those balloons are out of sight, they don’t cease to exist. They end up in beautiful places like our protected beach, where they stick around for a long time (especially the mylar ones; those things are nigh-indestructible). Then wild animals can encounter them.

So how can you help?

  • At home, dispose of items like balloons, plastic bags, yogurt containers, and fishing line properly.
  • Reduce the use of these items, and you’ll reduce their presence in the waste-stream – for example, use reusable shopping bags and washable containers.
  • You can consider volunteering with a beach clean-up program, like the California Coastal Cleanup Day on Saturday Sept 19, 2015 – but really, no need to wait, just pick up any trash you see when you go out to the beach!
  • Stop and help/report entangled or trapped wildlife; allowing permitted wildlife rehabilitation professionals to provide the care they need.

Be well, and thanks for caring about the animals!

Oil Spill Over, But Animal Care Continues

The following is a guest blog by Kelly Berry of International Bird Rescue.  Even though the majority of animals that we had in care from the spill have been released, our colleagues at International Bird Rescue and SeaWorld have been hard at work caring for the remaining animals.  Thank you for all the effort you have put into caring for the special cases that need a little more time before release! -Becky

When an oil spill occurs, the media rush in to meet the public’s desire to know what the environmental effects will be, putting forth iconic images of struggling wildlife and crude-covered habitats. They then go on to capture inspiring moments of cleanup efforts and successfully washed and saved animals. Unfortunately (and understandably), public interest wanes as the cleanup process draws down. The beaches are reopened for public use, and the majority of what the public sees has been neutralized. However, this is not the story’s end for wildlife rehabilitators and the affected wildlife that remain in care.

Hundreds of wildlife specialists across California are trained to rescue and rehabilitate wildlife affected by oil spills. Contaminated animals are rescued and transported to a wildlife hospital, where they are stabilized, washed to remove the oil, and treated for injuries. Sometimes removing the contaminant is not enough though; in fact, the crude very often masks secondary injuries and health problems. For example, the contaminant can render the animal’s primary defense against injury and harm—its hair, fur, or feathers—ineffective, leading to starvation, hypothermia, burns, and other wounds. The upshot is that animals impacted by oil spills often must remain in care longer than expected.

The recent oil spill near Refugio State Beach impacted hundreds of native animals, primarily sea birds and marine mammals, with the California Brown Pelican being the most affected bird. Wildlife hospitals, such as International Bird Rescue, were tasked to treat the contaminated sea birds. Trained technicians, volunteers, and veterinary staff at Bird Rescue spent countless hours washing and restoring the patients to full health. By the time the oil spill cleanup was over, all but three of the rescued birds had been given a clean bill of health and released.

One of the three, a Ring-Billed Gull (number R56), was emaciated and dehydrated upon admission into care; in addition, its feathers were in such poor condition that it could not sustain flight. This gull, which took several days of supportive care just to recover its willingness to eat, is currently molting and doing laps in the Bird Rescue aviary as it grows strong enough to fly. The second bird, Brown Pelican W19, came into care completely coated in oil. After W19 was washed, staff found a chest abscess that required antibiotics and surgery. The abscess was surgically removed, and the bird completed a full course of antibiotics. Now fully healed and flying beautifully, W19 was released on August 18. And the final patient, Brown Pelican W1005, was covered in oil and had a foot infection from an unknown source. This bird has been washed, has undergone two surgeries, and remains on antibiotics. W1005’s prognosis is guarded, but Bird Rescue staff are working hard to ensure it gets all the care it needs.

For each individual wild animal, the traumatic physical effects of an oil spill end when it is returned home. International Bird Rescue, along with every diligent wildlife organization that makes up the Oiled Wildlife Care Network, holds one basic conviction for dealing with affected animals: Every individual matters. The collective goal in our community is to restore every animal to full health and release it back into the wild.

Refugio Incident Update 8/19/2015

Photos and updates on animals affected by the Refugio Incident, provided by the Joint Information Center:

Three California sea lions returned to the wild off the California coast near San Diego on August 16, after wildlife care experts determined they were ready for release.  They were wearing satellite tags so scientists can track their activities following their rehabilitation after the oil spill. Wildlife experts captured the sea lions during the Refugio Oil Spill Response that started on May 19, when Pipeline 901 leaked oil into the Pacific Ocean in northern Santa Barbara County.

Have You Seen Me?

Green-banded (as well as blue-banded) pelicans are out there and we need your help in reporting them!  The green-banded birds are the Brown Pelicans that were brought to the Los Angeles Oiled Bird Care and Education Center during the Refugio Oil Spill. They were subsequently washed, rehabilitated, and released. And we want to follow them as much as we can and find out how they do. This is where YOU come in! This information is very important for figuring out what happens to these pelicans after they are released. Where do they go? What do they do? Do they survive? Do they breed successfully? These are just some of the questions that we would like to answer. There are very few studies out there that have successfully followed animals after an oil spill. And yet this type of information is crucial for helping determine the best care of oiled animals.

So if you see a pelican wearing some green jewelry (see picture), please report it here.

International Bird Rescue also bands pelicans that go through rehabilitation, but they band them with blue bands. If you see a pelican with a blue band, please report it here.

By reporting pelicans with colored bands, you will be contributing to expand the body of knowledge of what happens to animals after they are released.

Thank you in advance!

Bye Bye Baby!

Our great OWCN staff at International Bird Rescue released “the baby” this week with great fanfare (not to mention a lifeguard escort). Because few of us here in San Pedro had experience with fledgling cormorants, the baby provided both entertainment (those adorable squeaky sounds!) and education. We consulted with folks who have more experience with cormies at this age, so we all learned a little something.

The baby Brandt’s went from a fluffy puffball to a sleek, streamlined cormorant in the weeks he’s been with us, but that hasn’t stopped us from continuing to refer to him as a baby. I guess it is always hard to admit it when your baby grows up!

Kelly got some fantastic photos of his release, which as I mentioned included a boat escort by the Cabrillo Beach lifeguards so he could be released out on the water. A big shout-out to the lifeguards for helping to get this guy home!
