Brown pelican

Pelicanus occidentalis

Brown pelicans have been in the news recently for a variety of reasons; first, Browns are an endangered species, and there has been discussion as to whether or not it should be re-listed as "threatened", as there have been significant improvements in the habitats, food supplies and numbers of the species; second is that certain algae found in the ocean has affected some of the Browns in a way that makes them appear intoxicated, and they are being injured due to impacts with vehicles and the ground; third, young pelicans in the LA-SF region are being found malnourished, or even having starved to death as a result of less schooling fish being available for the higher numbers of successful chicks this year.

So what do these issues have in common? Well, to me the obvious answer is that if Browns are being injured and/or killed due to affects of ingested algae, and if they are starving due to a lack of food supply, then why is the government looking to take them off the endangered list?

This is a question which cannot be answered here, although in my own opinion, I feel that we need to look at the overall pelican picture and see how we, as the responsible party, can assist with the issues Brown pelicans are facing. The fact that the Brown is regaining health as a species overall is wonderful; the problem is that while there are more Browns, there are fewer and fewer fish in the ocean for them to catch, and fertilizers, etc., that we dump in the waters can cause toxic algae to get out of control. This means that while we have succeeded in building up the numbers of Browns, we have not done enough to correct the problems the birds face for ongoing survival.

The Brown pelican will win no beauty contests based on their looks. But they are extremely graceful creatures, particularly nimble in the air, and fantastic at catching fish. And you'd never know it, but their feathers are soft as silk, and they are quite easygoing.

The Brown pelican adult is about four feet long with a wingspan of 6.5- to 7.5 feet.

One of the main recognizable characteristics of pelicans is the pouch attached to the lower bill; the pouch can expand up to three times normal size, and is packed with blood vessels to help cool the blood. A pelican trying to cool off will open his bill and "pulsate" the pouch, allowing more air to circulate around the blood vessels.

The juvenile Brown pelican will be drab grey overall, with lighter underparts:

The adult (see photo at top) has a grey bill, a white head with a pale yellow crown, brown-streaked back, rump, and tail, pale yellow eyes and black legs and feet.

Being ocean dwellers, pelicans must deal with the accumulation of salt in their bodies. Salt dehydrates, and cannot be allowed to build up; as a result, pelicans (as well as other animals which live in saltwater) have "salt glands" in the skull, just above the eye sockets, which act as filters, removing excess salt from the blood, allowing the bird to excrete the salt and preventing health issues. When the glands excrete the salt (through the nares, or nostrils), it is watery, and looks like the bird has a runny nose! Sometimes, they will "sneeze" it out, which is actually quite comical!

These amazing creatures are diurnal (daytime) carnivores, with a diet consisting of schooling fish and the occasional crustacean. They are plunge divers, meaning they fly high above the water -- sometimes as much as 50 to 60 feet -- until they spot a group of fish, then tuck their wings in and dive into the water, completely submerging and popping up with a pouch full of water and fish. The pelican then drains the water from the pouch, and swallows the fish. Brown pelicans do not have tongues, but there are rough protrusions in the skin of the mouth and throat, and the wriggling of the fish helps get it down into the stomach.

Brown pelicans predominantly eat a type of herring called a menhaden.

Although considered inedible by humans, the amount of this fish caught in the US is higher than any other type of fish. The menhaden is used as bait by commercial fishermen, mostly for blue crab; it is also used for fish meal and oil.

According to the Menhaden Resource Council website,

"Fishmeals derived from menhaden provide a unique, high-protein blend of nutrients, and are an important component of many cattle, swine, poultry and aquaculture feeds.. The oil derived from menhaden -- rich in heart-healthy Omega-3s -- is an FDA-approved health food additive. Menhaden oil is currently used in a growing number of enriched foods including pasta sauces, salad dressings, sports drinks, baked goods and soups. It is also mixed with other ingredients for cooking oils and shortenings, as well as industrial products including lubricants, plasticizers, alkyd resins, and oils for paint and lipstick."

While the MRC website states that the Atlantic menhaden population is healthy and not overfished, it can still affect the growing populations of pelicans to have so many fish taken from the oceans. The MRC website also states that the MRC is dedicated to supporting the ecology of the menhaden, reducing bycatch (when something they don't want gets caught in the nets), and maintaining a healthy and sustainable menhaden population. To be fair, menhaden are not the only fish that pelicans eat, just the main portion (90% or more).

Nesting & Young

Brown pelicans nest on the ground, in bushes, or in trees, usually with a clutch of 2-3 chalky white eggs, which are incubated for approximately 30 days; the chicks fledge in about 35 days if nested on the ground or in bushes, 63 to 88 days if nested in trees.

The pelican parents will only raise one brood a year, which is a big reason why it is extremely important that all chicks are successful. In the 1960s and 1970s, a pesticide known as DDT caused widespread population decline in multiple species of animals. The DDT affected birds by causing thin eggshells, which of course lead to extremely reduced numbers of offspring. This is what happened to the Brown pelican; at one time, it was estimated that there were less than 100 individuals in the wild.

Some interesting tidbits about the Brown pelican:
*A healthy adult weighs approximately 9 pounds; they have many air sacs throughout the body to allow them high buoyancy, and to soar the long distances required for migration
*Pelicans are the only birds in which all four toes, including the rear toe, are webbed together; this is called totipalmate
*Contrary to common belief, Brown pelicans do not carry fish in their pouch; food is swallowed immediately
*The pouch can hold approximately 3 gallons of water and fish
*A Brown pelican's bill is as long as their head and neck; they use the tip of the bill as a preening tool
*Pelicans fly with their necks folded up in an "S" shape

My pelican experience

Bird Girl and Nigel, July 2004

I had the most wonderful experience a couple of years ago when a pair of juvenile Brown pelicans had injured themselves when diving for fish -- into the mirages on the pavement here in the Valley of the Sun. One had a tear in his pouch, was malnourished and dehydrated; the other suffered a broken leg.

The two pelicans, whom we called Nigel and George while they were in our care, were very laid back, and not afraid of us at all. They loved having a kiddie pool to paddle around in, but we struggled with feeding them. Obviously, they can't dive for schooling fish in a tiny plastic pool!

The first day, we called everyone we know in our bird rehabber community to see if anyone knew ANYTHING about taking care of these birds. Ultimately, we ended up consulting with Sea World in San Diego regarding environment, feeding, anatomy, etc. They were so much help and we couldn't have done it without them!

Sea World told us that we could puree fish, add some vitamin supplements, and tube feed the pelican. Tube feeding, for those who haven't figured it out already, means inserting a tube attached to a large syringe into the "stomach" of the bird, and filling the stomach directly. It's one thing to tube feed a mourning dove or pigeon; it's quite another to feed a bird with a two-foot long neck that is fighting you every step of the way.

Jody and I decided we would try tube feeding Nigel (George was at the vet's recovering from surgery to repair his broken leg). She stood behind him and held his body and head in place, while I guided the tube down his throat and into his stomach. As I began to push the fish puree into the tube, Nigel shook his head and spit out the tube -- and covered Jody and me in fish soup!!! Let me just say, EEEWWWW!!! We had it in our hair, on our hands and feet, all over our clothes, on our faces...I must have washed my hair five times that night, and scrubbed off at least two layers of skin, trying to get the fish smell off! I have never liked fish, never eat fish, and have always hated the smell. This was just the WORST!!!

We decided, after four tries -- Jody holding Nigel and me feeding him; me holding Nigel and Jody feeding; Jody and me holding Nigel while another person tried feeding him; Jody and me holding the bird while a third person held his head, a fourth held the bill open, a fifth held the tube in place, and a sixth pushed the fish paste into the tube -- that it just wasn't going to work. We had wasted a good deal of fish and vitamins, and we all smelled horrible and felt worse because we were sticky with fish paste.

We consulted with Sea World again, and they said to get live fish and put it in the pouch, the bird would swallow the fish as normal. We were to try to give the bird vitamins, as well. The whole "live fish" thing didn't work out any better than the fish paste -- it's really hard to get a wriggling fish into the mouth of a big bird that really doesn't want your hand in his throat, not to mention cleaning the dirt off the fish after it flops out of your hand for the umpteenth time. We settled on thawed frozen fish instead, and put vitamins in the fish. It wasn't easy, but we did get the pelicans to eat these fish.

Making sure Nigel's fish goes down

The Trip
After both Nigel and George had achieved a healthy weight (Nigel was only 3 pounds when we got him -- he should have been 2-3 times that heavy), were completely healed of their respective injuries, and were flapping about wildly, it was time to send them off. We weren't allowed to release them in Arizona, however; the birds had to spend time at Sea World in quarantine and be approved for release by the veterinarians there (because the Brown pelican is an endangered species).

So I said, "I have an idea." Jody and I have been doing bird rehab together for about five years. She always winces when I say "I have an idea."

I suggested that we take the birds to Sea World ourselves, instead of shipping them by air. We didn't trust the airline industry to properly take care of our charges, to whom we were completely attached by this time. And so it was decided that Jody and I, along with Kay (another volunteer & our IT person) and two of Jody's daughters, would drive to Sea World with Nigel & George and deliver them personally.

We set out at about 11 pm, fueled up and stocked up, and unbelievably excited. From Phoenix, Sea World is between 5-6 hours' drive, depending on how fast one drives (I'm not saying that anyone was speeding, just to be clear!). We figured we would leave at night so most of the driving would be done while the birds were asleep, and so we would arrive in the early morning; we planned to drop off the birds, turn around, and come home. That's pretty much what happened, too.

When we finally got to San Diego, it was so early that we couldn't go to Sea World yet. We drove around until we found a place to have breakfast, and ended up at a little mom & pop diner that had just opened for the day. It was about 6:30 am, we were starving and tired, and had nearly three hours to kill before the person we were to meet would arrive at Sea World. Our waitress was really strange, half of the glassware and silverware was not as clean as it should be, and the food was not good at all. It was almost a Twilight Zone kind of thing, really.

We left the diner and headed to Sea World, knowing we would have to wait for our contact to show up. We drove around and around looking for the entrance that we were supposed to use (can't exactly show up at the ticket window with a pair of pelicans in an airline crate), and finally located the gate. There was no guard station or parking attendant or anything, no one to ask if our contact was there yet, or where we should park, or whatever.

It was just our luck that at that moment, someone pulled up next to our vehicle and said, "Are you lost?" We relayed our mission to this person, who told us that they knew the person we were there to meet, and would go inside to tell them we had arrived. We didn't have to wait for her after all!

Sea World
After being directed to the back side of the park, where the holding tanks and other "behind-the-scenes" things were, we parked and got Nigel and George out of the car. We were about to be given a tour of Sea World's Oiled Wildlife Center, where our pelicans would spend the first day or two. It is quite the operation they have there: rows of pens; rows of bathing tubs; rows of drying pens with heat lamps and fans; and of course, VATS of Dawn dish detergent! No one was in the building (by that I mean, no birds), so Nigel and George would have the place all to themselves. We were so excited to be there. It was amazing.

We were led on a tour of the facilities, including the Humboldt penguin habitat, the pelican habitats, the hospital and the nursery. These are things that aren't even on the "Behind The Scenes" tour! We saw different types of marine mammals which were being kept off display for one reason or another, including seals, dolphins, walruses, etc.

The most exciting thing about this tour, however, was being able to see all the BABY FLAMINGOES!!! We even got to interact with one, all of us sitting on the floor in a circle while the baby wandered around, fascinated by the new people and voices, my sunglasses and Kay's camera. The baby chattered the entire time, too, it was so cute! He was nothing but beak and legs with a cotton ball in between! He was still downy, and was softer than anything you can imagine. His down was so soft that you almost couldn't feel was so amazing.

We went back to the center where our pelicans were, and collected our crate. We all said goodbye to Nigel and George, who were excited at the prospect of the fish that they could see in the caretaker's hands. With a big "squawk!" they waddled out of the crate and into the pen, where they happily swallowed several fish each. Jody, Kay and I all cried.

Nigel and George in their crate

After our special tour, we were allowed into the park for free! Imagine the cost of five adult admissions to Sea World! We were so extremely grateful for the tour and the park access. We spent a couple of hours looking at some of the exhibits and shows, but then we had to get going again.

We headed back to Phoenix, excited but exhausted, happy but sad, and dreaming of Nigel and George being free. We returned home at about 11 pm, just 24 hours after we left! Think of it -- in ONE DAY, we left Phoenix, drove to San Diego, had breakfast, toured the facilities of Sea World, spent time in the park, and drove back home. WHEW!!!

A couple of weeks later, we received a letter from our friends at Sea World. The two pelicans we had delivered to them were the healthiest that had been received by any of the Phoenix-area rehabilitators, and our pair had been released only a week after arriving at Sea World; the others had to continue rehabilitation for a week or more after ours were released. We sent one of our logo t-shirts as a thank you, saying that we hope to work together more in the future.

In my dreams, I see Nigel and George with families of their own, diving into the ocean and coming up with a belly full of fish. I imagine that someday, just maybe, they'll fly over my house and dip their wings in a quick "hello"...

Owlet defends nest from Fox

I found this clip while following a series of links from a German livecam. It shows an owlet, one of three in the nest, defending his home and siblings from a hungry fox. (Spoiler: the fox does not win. I knew you'd be worried)

Here's the text of the link if you cannot get to the clip from the hyperlink above. Be sure it is all on one line and has no spaces:

Hugo the Stork

One of the stork cams in Germany has a single chick, named Hugo. He is being raised by adoptive stork parents.

There have been a few deaths of stork chicks in Vetschau, and recently information has been released as to the cause: a fungal infection called Aspergillosis. From the website:

What caused Lenka's Death?

The Institute for Fowl Diseases of the University of Berlin forward a preliminary finding of the cause of death of Lenka.

Diagnosis: Aspergillosis (a rare ailment of animals in the wild, most often a lung disease triggered caused by the mould fungus aspergillus fumigatus)...

As far as Hugo is concerned, we can only hope that he will survive. He came to the eyrie later and is already much larger, so that he not become profoundly infected. A treatment is out of the question. We keep our fingers crossed. Continuing searches for causes were already decided upon by NABU, Regional Association Calau. The nest material which the storks bring to the eyrie has to be the main focus.

After the last brood period, eight inches of nest material was removed from the eyrie which was treated twice in autumn and once in spring for mould fungi. Were these measures insufficient or was the fungus reintroduced with the new material? Many questions which need to be cleared up.

Winfried BoehmerNABU-Project Leader"

Aspergillosis is something I see on very rare occasions in my own wild bird rehabilitation group here in the Valley of the Sun. While technically not transmissable between animals and humans, people DO get aspergillosis, by inhaling the fungal spores from the environment -- not directly from the infected animal.

Aspergillosis is NOT "Valley Fever" -- this condition is actually called Coccidioidomycosis, and is caused by Coccidioides immitis which is present in the dirt. A person coming down with Valley Fever is much more likely than a person falling ill with aspergillosis.

It is always heartbreaking to see new life succumb to disease. The article above mentioned the removal of several inches of material from the nest, as well as treatment of the nest to try to rid the area of the offending organism. Unfortunately, we cannot control all aspects of an environment, and try as we might, babies will still die as a result of naturally occuring microscopic organisms.

Today, Hugo seems stronger than the last few days, and is even standing up a little bit, stretching those long legs. His breathing does not seem to be as labored, and he is much more alert. I hope this means he is going to survive. He sure is cute!

MD Ospreys

The MD ospreys have four VERY healthy chicks, and the parents spend virtually every minute catching fish and feeding the chicks. Quite the contrast to the CT ospreys, with only one chick there is not as high of a demand for food, so the parents can rest a bit more.

On the gallery page of the MD Osprey cam, I found a few pictures that I thought I would share.

Check out how BIG this fish is!!! Compare it to the size of the bird's leg -- it's a whopper!

This one is so cute -- all four chicks lined up in a row at Mom's feet!

The whole family, you can see the bigger chicks are standing tall now.

The picture below is not of one of the CT or MD ospreys, but I thought it was really great. You can really see the primary feathers, the banding on the tail...

Here is the taxonomic nomenclature of the Osprey (Pandion haliaetus):

Ciconiiformes (also referred to as Falconiformes though it is no longer used)
Species: haliaetus

NCTC comments totals

It's almost absurd how many comments have been posted on the NCTC Bald Eagle LiveCam (! Is it possible that it will hit 1000 on a single post? What will happen if it does?

Check out the article and video about George and Martha, a mated pair of Bald Eagles in D. C. who live near the Woodrow Wilson Bridge. The rescue center who cared for Martha is Tri-State Bird Rescue & Research in Delaware.

Long day doing bird rehabber stuff, so no other posts today...

June 15th pictures

This is from a few days ago.. Dad feeding Mom while she warms up Baby. All together, now: AWWWWWWW!!!!!!!

Dad's second Lookout Perch. Lots of junk in the nest now. Eww.

This morning's breakfast, which was stashed near the black stuff, couldn't really see it before. She spent a lot of time looking around, while Baby flailed around trying to get her attention. Mom eventually did feed Baby, but she seemed pretty nervous. Maybe there is another bird in the area pestering them. Note the egg, still unhatched, next to Baby. The other egg is gone.

MD Ospreys have four chicks, as shown below:

H5N1: Avian Influenza

Please see my post regarding "bird flu" on my primary blog.

This is an amusing little site about a family with several pet ducks. The website's author is very clever and takes very good pictures, plus there is a live cam!

And check out this movie on her site of one of the ducks playing with a stuffed toy chicken. It's too funny!!! (Quicktime required)

CT Osprey

The first picture shows the nestling and two eggs circled in green. Since early this morning, one egg has been pushed over to the side; the other egg is still in the center of the nest, but Mom keeps fiddling with it. I don't think we'll see those eggs hatch.

The second picture is of Mom tidying up the nest. Of course, all that means to an osprey is "move this piece of trash over here, that one over there..." She won't be winning any Good Housekeeping awards, that's for sure!

The third picture is to show you where the "lookout" perch is. You can usually find the male sitting on the Lookout when Mom is sitting on the nest.

I will not be online all day every day, but when I am, I will post new pictures. Please email me if you have any pictures you would like to see posted here!
