Information for our May field trip to Southern Utah:
Trip is tentatively planned for May 2nd-4th. The bunkhouse at Lytle will sleep 12 women and 12 men and has cooking facilities, so there is plenty of room In order to reserve space at Lytle Ranch for the night of May 2nd I need to get a count of people ASAP who would be interested in attending. We may choose to spend the second night in Cedar City in order to bird Iron and Beaver counties on the way home. Please email, call or text keeli at [email protected] or 801-602-9566 with questions or if you think you might be interested in attending. We will plan on hitting at least 3 counties on this trip for our 2014 birder challenge.

April Captainís Log: Bird adaptation for staying on the ground.
A couple of months ago I wrote about characteristics of birds that make them uniquely adapted for flight. In this monthís article, I will discuss those that have lost the ability to fly Ė and some of the interesting adaptations they have developed instead. Flying is to birds like water is to fish, right? Not for these guys. Flightless birds are a unique and diverse bunch. One would think that as a bird, losing the ability to fly would greatly reduce your options in life, but as it turns out, there are a few benefits. Flightless birds no longer require the massive energy investments needed to develop and carry around the enormous flight muscles, wing structure, or keeled bone structure required for flight, nor do they have to constantly feed to fuel those muscles in flight. This also has the added benefit of allowing some species to be very very large- larger than they could ever be if they could fly. (No- ostriches, Iím not calling you fat. Youíre just big boned, I promise.) As it turns out, however, large herbivorous birds still have to consume a great deal because of the lower caloric content of their plant-based diets. Many of them, like the ostriches, have evolved large intestines to deal with the large amount of plant matter they consume.
If life is so good being a bird on the ground, then you may ask, why did birds take to the sky in the first place? Extinct flightless species like the Dodo, the Great Auk, the Moa, and the Elephant Bird could probably answer that for you. Being tied to the ground makes you much more vulnerable to being eaten, especially when humans and human-introduced predators such as rats and cats become involved.
Flightless birds that have successfully survived extinction-this long at least- have evolved a number of defenses to counter the threat of predators on land. Some, like penguins, have evolved as very strong swimmers and virtually fly through the water instead of the air. However, awkwardness out of the water still makes them vulnerable to predators on land. Most penguin species are fortunate to occupy some of the more remote and less populated places still left on the earth, so theyíve got that going for them as well.
Another group of flightless birds called the Ratites include Ostriches in Africa, the Emus in Australia, Cassowaries of Australia and New Guinea, the Rheas of South American, and the Kiwis of New Zealand. These species (with the exception of the kiwis) are all larger bodied birds that have evolved strong powerful legs and are very fast runners adept at using their legs or their feet for defense or escape. Ostriches and Emus can reach speeds of 30-40 mph. In many places ostriches and emus have been domesticated, and are commercially farmed for their feathers, meat and skin. Can you imagine herding a flock of ostriches down the road?
Unlike their larger cousins, the Kiwis of New Zealand are much smaller nocturnal flightless birds that have committed 100% to the flightless gig and have tiny hidden vestigial wings (no longer functional in any way shape or form) and an obvious lack of any external tail. They have the unique distinction of laying the largest egg in proportion to body size of any bird, laying an egg up to one quarter of the femaleís weight. Not that comparing live birth to egg laying makes sense on any level, but thatíd be like a smallish 120lb woman giving birth to a 30lb baby! Carrying around that kind of egg weight is clearly not something that would ever be sustainable in a flighted bird. The kiwis, unfortunately, are threatened or endangered across most of its distribution due mostly to loss of habitat and introduction of human-introduced mammalian predators.
Well that pretty much sums up the flightless birds for this month. Just a word of warning, if you meet a cassowary in the forests of New Guinea, you might want to give it some room. Those talons arenít just for show.

When people ask me ďWhatís your favorite bird?Ē my answer is usually ďThe one Iím looking atĒ. However, when push comes to shove, I would have to say my favorite, at least at one of my top 10, is the American Avocet. I remember the first time I saw one. It was at Lindon Boat Harbor. As soon as I saw that cute thin upturned bill, I was hooked. I love their cinnamon colored heads, that long, thin, upturned bill, the striking black and white pattern of their wings and backs and the fact that they are easy to identify.
Enough reminiscing. Letís get down to facts. The American Avocet is about 18 inches with a wing span of 32 inches. Its structure is long legs and neck with a chunky body, small head and upturned bill. As mentioned, they have a bold black and white pattern on the wings and back and cinnamon colored head and neck, which turns gray in winter. The Avocets walk steadily through shallow water swishing their bills from side to side to feed.
The call of the American Avocet is a high bleet, higher and more emphatic when alarmed. (Thatís kinda cute too!)
The American Avocet is common through the West and South, but scarce in the Northeast. They are an intermediate-distance migratory, migrating primarily through the interior. They winter from Northern California to SW Guatemala, Belize and Cuba. The Avocet departs its wintering area mostly in March or early April. We can expect to start seeing them here in Utah mid-April to May. (I saw my FOY on the UCB field trip March 15th @ Chicken Creek, thanks for the spot Milt). They will start returning to their wintering grounds anywhere from July to September.
Some interesting facts:
American Avocet will feed day or night. They eat a variety of aquatic invertebrates as well as small fish and seeds.
They have only one brood per season, but will re-nest after a failure.
Both adults will share parenting duties.
Over all a perfect little package. Enjoy this seasons Avocet population. Bleet, Bleet!

Field Trip Report
Weber and Davis Counties - 29 March 2014
by Keeli Marvel
We had 25 birders join us on Antelope Island for our field trip on Saturday. The birding along the causeway was pretty slow, but we did see Long-billed Curlews and fly-by views of a Great Blue Heron. On the island we did the northern loop around and up to the visitorís center with a couple of stops. The Chukars were out perched on the rocks, and we spotted a couple of Loggerhead Shrikes at one of the parking areas north of the visitorís center. At the visitorís center highlights included Yellow-headed, Red-winged, and Brewerís Blackbirds, a pair of Sayís Phoebes, more Chukars, a lingering White-crowned Sparrow, and some Rock Wrens. We dipped on seeing any Burrowing Owls, but at the hay barn by the bison corrals we got a Barn Owl in the box and a Great-horned Owl perched in the rafters. After most of the people in the group had 29 species on the island the group split up and went several different ways. A couple of parties stayed on the island to continue birding, a couple of cars headed north to Box Elder County, and the car I was in plus one other vehicle headed north into Weber county. We stopped at Ogden Bay (still a mess, but not actively under construction while we were there), where highlights included Green-winged and Cinnamon Teal, Sandhill Cranes calling, a Herring Gull mixed in a large flock of California and Ring-billed Gulls, a Kestrel perched near a Kestrel box and a pair of Ruby-crowned Kinglets in the neighborhood south of Ogden Bay. We finished off our list driving north through Hooper and Warren to where 2150 N crosses First Salt Creek where highlights were three or four Wood Ducks, and some Black-capped Chickadees in the creek along an access road on the northwest side. Complete lists of species are included below.

Best bird of March has to be California Quail on my platform feeder that is eight feet high.
Jeff Cooper - Pleasant Grove
California Quail found their way into my yard several times during the
Eric Huish - Pleasant Grove
A couple of returning Turkey Vultures flew over the house.
Keeli Marvel - Saratoga Springs
Sandhill Cranes heard from inside my kitchen flying over my house. Real excited that my new house is so close to Utah Lake.
Milt Moody - Provo
A Western Screech-Owl checked out my owl box for a few days, but probably found better accommodations elsewhere.
Bruce Robinson - West Jordan
Cassin's Finch - First one since 2011 in the yard.
Dennis Shirley - Elk Ridge
A male Downy Woodpecker drumming his heart out on 3/26/14.
Alton Thygerson - Provo
Eurasian Collared-Dove - I canĻt believe that I put this bird as my favorite backyard bird. They have displaced Mourning Doves who once fed in the yard. However, their coo call is peaceful in the mornings. They tend to feed in the late early evening hours.
