What do birds eat?

Photo by John Crawley


The better question would probably be what donít they eat? Bird diets vary in about every way imaginable and what they eat dictates just about every aspect of their lives. This includes where they live, when they live there, when and where they migrate, even how colorful their plumage is.


Birds can be separated into two categories depending on their diets. Generalist feeders use various means of getting their food or eat a variety of food items. Specialists are birds that use a single method or strategy or eat a single type of prey item. Some birds eat seeds, fruit or plants, some eat insects or crustaceans, some eat other birds, some eat fish or mammals, and some birds (the generalists) can vary their diets by season or food availability to eat a combination of these things. Many bird species or families such as skimmers, toucans, flamingos and crossbills have specially modified bills that have evolved to exploit a very specific type of food item.


Birds have a highly efficient and unique digestive system that includes a storage tank called a crop where food can be stored temporarily, and a super stretchy esophagus that allows many species to swallow large prey items whole. Because food often gets ingested whole, birds are also unique in having a special chamber in their stomach that helps grind up food, often with the use of sandy grit which the birds will actually ingest. This chamber is called the gizzard, and it performs the function that our own molars perform in grinding up the food (because birds donít have molars!)


Many bird species have very specialized diets. Phainopepla (which many of you are familiar with if youíve ever visited Lytle) are mistletoe specialists and the majority of their diet consists of mistletoe berries. The huge populations of Eared Grebes that migrate through Utah are saline lake specialists and most of them spend their time here at the Great Salt Lake feeding entirely on brine shrimp and brine flies at the Great Salt Lake. Large migrating populations of Eared Grebes can be found on other saline lakes as well, such as the Salton Sea in California.


Birds in the flamingo family are saline lake specialists as well, and get their pink coloring from alpha and beta carotinoid pigments from their filter-feeding diets. The brighter their plumage, the healthier and more well fed the birds are, and the more desirable they are as mates to other members of their species. In the bird world itís not who you are, but often how much you eat (or can provide for her to eat) that gets the girl.


The Secretarybird of Sub-Saharan Africa is one of my favorite birds because of its unique method of finding and capturing its food. If youíll imagine a raptor similar to a Crested Caracara with the supremely long legs of a crane (they can get up to 4 ft tall!) you might get a good visual picture. Secretarybirds find their food by stalking through fields and stomping on vegetation to drive out prey. Often when prey emerges (snakes and small mammals), they stomp on the prey to disable it enough to gobble it up. Sometimes their prey includes very poisonous snakes like adders and cobras. I would stomp on them too if thatís what I had to eat! STOMP STOMP STOMP.


I really could go on forever about the interesting things and ways birds eat, but Iíll leave you with one more of my favorite examples. The Hoatzin bird of South America is the only known species of bird that has evolved a digestive system that is more like a cowís than a birdís. Cows have a four part stomach that includes a special pre-stomach called the rumen. Cows process their food multiple times by eating it, fermenting it in their rumen, regurgitating it and chewing it again (you might have heard this referred to as chewing their cud), and then swallowing and completing the digestive process. This allows them to break down and absorb nutrients from the cellulose in plants that is typically hard to digest. Hoatzin birds eat large amounts of leaf matter which requires the same process of foregut (in their case crop) fermentation to break down. They are often observed loafing around chewing their cud while the incredibly long digestion process takes place. You can imagine the smell of all that fermenting plant matter; that explains why they are often referred to as Stink Birds. Yum!


Well this wraps up my brief coverage of what birds eat. Thanks for joining me. Tune in next month (same bird time and same bird place) for more informative (and hopefully entertaining) facts about birds.


Happy Birding!

Bird of the Month

Say's Phoebe
Sayornis saya

My First Utah Friends

Coming to Utah four and a half years ago, for what I thought was only a brief time, was, to say the least, a difficult transition. For the previous 6 months I had been living in Fiji and was just beginning to enjoy retirement, the laissez faire mentality of the Fijian people and the constant 85 degree climate. Not to mention the fantastic scenery, isolated beaches and lagoons and phenomenal birding opportunities.

Notwithstanding I was glad I could contribute to my sonís educational goals and coincidentally spend more time close to him, I suddenly found myself at the other end of the climatic, cultural and life-style spectrum in Utah with only a cursory knowledge of the state and no friends. I more or less languished in our Utah County condo until one day in mid-April of 2011 when I heard an unfamiliar bird calling mournfully from just outside my bedroom window. Going out to investigate, I discovered a male Sayís Phoebe perched on a sign post who then posed very cooperatively for a photo. Within seconds, I had made my first ďfriendĒ in Utah.

A few days later I observed him with his mate, and for the next two months they were just outside my window nest-building and raising their family. Though I never actually saw the nest, I assumed it was somewhere within a large pile of concrete and old lumber in a vacant field behind the condominium because thatís where they generally were perched. Each day I would go down stairs and hide near the trees in the back and watch them faithfully going about their prescribed parental duties, and when they came close enough, I would talk with them one-on-one. One or the other of them seemed to follow me out to the garage each day and sit atop the roof and call. I fantasized that they had become as attached to me as I was to them. But, in reality, Iím sure they were just tolerant of my presence. Around the middle of July in 2011 through 2013 they would disappear. Through research into the species I learned that Sayís Phoebes typically migrate north from their wintering grounds in Mexico and Central America beginning in late March and return south in early fall. Knowing that they can travel as far north as Alaska and the Yukon, I have felt very privileged that this pair had chosen the field behind my condo as their summer residence. Where they went after raising their family is a mystery as they likely didnít return to their winter home until a couple of months later.

As I write this my heart is a bit heavy because the male has been here for the past two weeks. I hear him calling incessantly each morning. To my ear his call is sad and pitiful because the female has not appeared and we both are longing for her return. He perched on my deck railing a couple of days agoóa first in the three years weíve know each otheróand peered through the window as if seeking my help in locating her. I felt helpless that I could not intervene in his behalf. If she doesnít come back soon I hopeóand yet fear-- he will move on and seek another mate. The species is monogamous, but I cannot determine if they stay together during migration or if their travels just coincide. At any rate, I have enjoyed our ďfriendshipĒ over the past three years, and wish him, and her, god speed.

Field Trip Report
Tooele County -
5 April 2014
by Bryan Shirley

This morning 3 of us had a good morning in Tooele County. We started off in 5 mile pass with several singing Sagebrush Sparrows and Sage Thrashers. At Fitzgerald WMA we added about 30 species quickly - all of the common waterfowl was there, including about 40 RB Mergansers. There were a few migrant arrivals too like Avocets and Tree Swallows. Our next stop was Clover Springs Campground. Overall it was not very birdy, but we did see a couple of Belted Kingfishers, a small group of Bushtits and a Juniper Titmouse. Rush Lake is packed with several thousand ducks, but most were too far to see well. Our last stop was at the Mill Ponds in Stansbury. Not a lot of ducks there now, but there was a DC Cormorant and a bunch of raucous GT Grackles. Our final list for the morning was 51 species.

 


Field Trip Report
Box Elder and Cache Counties -
12 April 2014
by Keeli Marvel

3 Utah Birders met last Saturday to bird Box Elder and Cache counties. Our first stop was the Bear River Migratory Bird Refuge visitor's center. It wasn't open yet, but we birded the ponds around the visitor center and picked up most of our county species for Box Elder county. A quick drive a couple of miles west toward refuge picked up the rest of our 29 species for the challenge for Box Elder county. Highlights included FOY swallows, FOY Swainson's Hawk, and several Long-billed Curlews in the fields along the road.

From there we drove through Brigham City and up Sardine Canyon. We picked up a few species at the summit, and then through Logan valley and into Logan, to the Logan River Wetlands just west of the Logan Landfill. This place was just full of birds. Highlights here were 10 species of ducks, a FOY Franklin's Gull, FOY Cattle Egrets, and FOY Black-necked Stilts. We also met up with Alton Thygerson at this point to show off the Cattle Egrets we were excited about finding.

On our way back to Utah County, we stopped to pick up a few Davis county species for a couple birders in our group who still needed birds in that county. Odgen bay was pretty messy with limited access, and the wind had picked up at that point, so we didn't quite get 29 species before it was time to head back.

Complete lists of species seen below. Happy Birding!
