Merrill's Musings
By Merrill Webb

Tyrant Flycatchers

Nineteen species of the family Tyrannidae have been documented in Utah. On the official state checklist four of these (Least Flycatcher, Eastern Phoebe, Great Crested Flycatcher and Scissor-tailed Flycatcher) are listed as either “occasional” or “accidental”. One (Brown-crested Flycatcher) is listed as “rare summer” because it is found typically only in the southwestern corner of Washington County. That leaves fourteen species of flycatchers that can be looked for in eight of the 29 counties of Utah for the birding challenge. However, it is not as simple as it appears (as has been pointed out to me by some of you participating in this year’s challenge). Five of these fourteen flycatchers belong to the genus Empidonax. Quoting from my 1961 copy of Roger Tory Peterson’s A Field Guide to Western Birds, “Small flycatchers in w. N. America share in common the characters of dark back, light underparts, light eye-ring, and 2 white wing-bars.......They are more readily identified by nesting habits, habitat, and voice than by subtle color differences. Unfortunately, in migration they may depart from typical habitat and they seldom sing their names. Collecting has proven that it is nearly impossible to name many individuals in the field, even in the spring, so the wise field man usually lets most of them go as just Empidonaxes.” Then, from my 1980 edition of Peterson’s A Field Guide to the Birds, the following statement, “Five small flycatchers in our area share the characters of light eye-ring and 2 whitish wing bars. When breeding, they are readily separated by voice, habitat, and way of nesting…..In migration they seldom sing, so we are forced to let most of them go simply as Empidonax flycatchers.” From my 1990 edition of Western Birds, by Peterson, he adds, “….If you wish the challenge of trying to name them in migration, study Kenn Kaufman’s Field Guide to Advanced Birding, but first know each one well when it is on its nesting ground, singing and calling.”

The months of May and June are critical months for getting out and finding these “empids”, as well as the other flycatchers. Below is a list of habitats and counties where flycatchers are most likely to be found during breeding season. This data is based on the Utah Bird Distribution: Latilong Study (1983), which in many respects is outdated, and my own experience with this group of birds.

Olive-sided Flycatcher - (high coniferous forest); counties: Davis, Garfield, Kane, Morgan, Salt Lake, Sanpete, Summit, Tooele, Utah, Wasatch and Washington.

Western Wood Pewee - (deciduous forest and river groves); counties: almost all counties in Utah.

Willow Flycatcher - (willow thickets); counties: Box Elder, Cache, Davis, Garfield, Kane, Sanpete, Tooele, Utah, Wasatch, and Washington.

Hammond’s Flycatcher - (high coniferous forest); counties: Box Elder, Cache, Sanpete, Tooele, Utah, Wasatch; and in migration, Davis and Washington.

Gray Flycatcher - (sagebrush, pinion, and juniper); counties: Iron, Kane, Juab, Millard, Tooele, Uintah, Utah; migration, Davis and Washington.

Dusky Flycatcher - (mountain chaparral); counties: Beaver, Box Elder, Cache, Davis, Iron, Juab, Kane, Millard, Salt Lake, Tooele, Utah, and Wasatch.

Cordilleran Flycatcher - (moist woods, mixed or conifer forests, shady canyons); counties: Beaver, Box Elder, Cache, Iron, Kane, Salt Lake, Sanpete, Utah and Washington.

Black Phoebe - (shady streams, walled canyons, towns near water); counties: Washington, Kane, and San Juan.

Say’s Phoebe - (scrub, canyons, ranches and mostly open areas); counties: widespread distribution, in most Utah counties.

Vermilion Flycatcher - (wooded streams in arid country, golf courses); counties: Kane, (rarely in San Juan) and Washington.

Ash-throated Flycatcher - (semi-arid country, deserts, pinion-juniper, open woods); counties: Beaver, Box Elder, Iron, Juab, Kane, Millard, Sanpete, Tooele, Uintah, Utah, Washington.

Brown-crested Flycatcher - (cottonwood-riparian areas); Washington.

Cassin’s Kingbird - (semi-open high country, pine-oak mountains); counties: Kane, San Juan, Washington, Wayne.

Western Kingbird - (agricultural areas, semi-open country, roadsides); counties: most counties in Utah.

Eastern Kingbird - (river groves, farms, Provo airport dike, fencerows); counties: Box Elder, Duchesne, Uintah, Utah.

Now all that is necessary is to be able to identify their songs in their favored habitat. The Stokes Field Guide to Bird Songs (Western Region) with recordings by Kevin Colver from Elk Ridge contains every one of the songs of the birds listed above, and most of them were recorded in Utah.

Based on the above information the best counties in which to find eight species of flycatchers during the breeding season are the following: Washington, Kane, Utah, Tooele and Sanpete followed closely by Davis, Iron and Millard. During migration these species can be found in other counties, but it is more challenging to identify them because they are not singing and are not in their typical habitat.

Recognizing that about half of these counties are in southern Utah, and because of increased gasoline prices, I am suggesting that instead of eight counties for the challenge, the number be reduced to four—that would also apply to warblers and sparrows. And, in terms of adding eight new species in eight states, the number should be reduced by half as well. For those of you who have already accomplished the state requirements we can make some substitutions on an individual basis.
If the price of gas continues to escalate (four dollars per gallon) I am in favor of eliminating the whole idea of a challenge for this year. I am not suggesting that these requirements for this year’s challenge are unattainable, far from it—just that it is becoming too expensive to continue.

For those of you who have read this far, and who have been making a conscientious effort toward completing the challenge, please be prepared to give me your input at the next meeting. Be thinking of some alternatives that pertain just for Utah County, and give them to me in writing before the meeting.

Bird of the Month

Bobolink

Class:    Aves

Order:    Passeriformes

Family:  Icteridae

Genus:   Dolichonyx

Species: Dolichonyx oryzivorus

 

Any trip to the fields north of Goshen during breeding season is not complete unless a birder can tick off the Bobolink on his checklist.  Its main territory is north and east of Utah, but we are more than happy to have a few patches of grassland near us where it also breeds.

 

This black 7” wonder with the conical beak, has white patches on his shoulders and rump and a buff nape and back of head.  (I think he needs the assistance of a personal shopper myself, or at least an honest friend who can help him get a cap a few sizes larger so it covers all his head and not just the back.  I’ll bet he bought that one at a garage sale.)  The Bobolink has two complete molts each year.  All the new feathers it produces on its wintering grounds have yellow tips making it look much liked a non-breeding bird.  But in time the tips wear off and the plumage is left with its dramatic breeding coloring.  The Bobolink is dichromatic, meaning the male and female look distinctly different.  The female looks more like a sparrow than it does its mate, but only during breeding season. 

 

The male wins his mates in the usual blackbird fashion.  He drops his head, ruffles his neck feathers, fans his tail, arches his wings displaying his prominent white shoulder patches, and the females fall at his feet, so to speak.  Federal marshals do not interfere with this polygamous bird.  Older Bobolinks may have as many as four nesting females in their territory, but most of their time and attention is devoted to the first family they produce, taking care of the others as time and resources permit.  Excuse me!  That is a lousy show of responsibility!!  Aha, read on.  They also engage in cooperative breeding, a seeming rarity among long distant migrants.  This is where more than two adults participate in the feeding of the young at a single nest.  The extra adults may be male or female, may be previous offspring from one of the adults, may actually be the birth parent of one or more of the young on the nest, or may have lost their own young and still be ruled by their biological urge to feed.  The Bobolink’s clutch size is four to six eggs and their nest is on the ground leaving it vulnerable to early field mowing.

 

The Bobolink’s flight is strong and undulating.  They migrate to southwestern Brazil, Paraguay and northern Argentina, with some stopping off in Peru and Chile, a round trip of up to 12,500 miles.  They migrate at night in flocks called chains, guided by the earth’s magnetic fields and the position of the stars.  Before their overseas flight, they fatten up on food in the southeastern United States.  When it was discovered that huge flocks, often at night, were descending on rice fields to increase their stores of fat, they were hated and killed. In one year there were 720,000 rice birds killed and sold as food.  In this plumped state restaurants served them as butter birds, a more appetizing name than meadow wink, reed bird or skunk blackbird, which are other names they are known by.  Despite their consumption of great quantities of rice, they are now considered a benefit to farmers.  Their main staple is an assortment of insects, and the seeds they subsist on belong mostly to weeds.

 

The Bobolink’s song has been described as “a bubbling delirium of ecstatic music that flows from the gifted throat of the bird like sparkling champagne,” and as “a tinkle of fairy music, like the strains of an old Greek harp.”  Poets as popular as Emily Dickinson and William Cullen Bryant have used their talents to describe Bobolinks.  We may also enjoy his song and attempt to describe him, but any description thus far produced weakens at the actual sight of one in breeding plumage sitting on a fence post with a swaying field of grass in the back ground.   This is what bird watching is about and we feel a sense of gratitude for this kind of experience as we tick his name off on our checklists.

Field Trip Report
East Canyon Lek
- 12 April 2008

by Merrill Webb

 

Saturday, April 12, some members of the Utah County Birders visited the Henefer Sage-Grouse lek. Observed approximately 60 grouse, many right on the edge of the road which provided good opportunities for photos for many of our group. I was pleased with the behavior of all observers since there were many other cars parked observing the behavior of the grouse. No one got out of the cars to try to get closer looks. We then went down to East Canyon Reservoir where we observed some loons and quite a few species of ducks. We then left that reservoir and traveled to Deer Creek Reservoir in Wasatch County where we saw 14 species of waterfowl. Birds are listed below.

D=Deer Creek Reservoir

Field Trip Report
Ouray NWR and Uintah Basin
- April 26, 2008

by Lu Giddings

 

I enjoyed near perfect weather in the Uintah Basin yesterday. It is early enough that there absolutely no annoying flies just yet. The plants are several weeks behind those along the Wasatch Front as none of the trees have yet began to leaf and none of the shrubs or flowers have started to bloom but it was mostly clear, warm, and beautiful all the same. Notable observations include, in no particular order:

- A pair of sandhill cranes dancing and foraging on the snow near Daniel's Summit.
- Friday evening, during the period from about thirty minutes before dark until roughly thirty minutes after it became dark, I observed seven different great-horned owls in the Ouray NWR-Pelican Lake vicinity.
- A pair of great scaup were observed at Pelican Lake.
- There were an number of first-of-season birds for me including sora, spotted sandpiper, marbled godwit, western sandpiper, least sandpiper, pectoral sandpiper, long-billed dowitcher, Bonaparte's gulls, plumbeous vireo, house wren, and blue-gray gnatcatcher.
- Four very late winter raptors were observed including a rough-legged hawk at Ouray, a merlin north of Pelican lake, and a pair of juvenile bald eagles foraging in a pond in the Pelican Lake vicinity.
- A nest tree with two great blue herons and seventeen double-crested cormorants was seen.

Probable sightings but not confirmed: peregrine falcon, Baird's sandpiper, lark sparrow.

Notable misses:
- Some spring birds are still not apparently around. No western tanagers, empids, white-throated swifts, lazuli buntings, black terns, etc. were seen. I was afraid this trip was a week or two too early for these species and I appear to have been correct.
- I also did not see any great egrets, cattle egrets, or black-crowned night herons, all of which were expected. I don't know if it's that the refuge is still pretty dry or if their presence is more seasonal than I expected.
- Sparrows were extremely few and far between, excepting song sparrows, spotted towhees, and the odd occasional junco.
- Where are Ouray's woodpeckers? I heard one norther flicker in Ouray, but I did not see any birds in this family until I drove past a Lewis's woodpecker in Woodland Hills yesterday evening.

Field Trip Report
Provo Airport Dike
- 28 April 2008

by Lynn Garner

Monday morning at 8:00, eight birders met at the east end of the Provo Airport dyke road for a field trip. Superb weather made it a great day for birding. We were greeted as we met by a pair of Eurasian Collared Doves and when we returned at 11:45, we were greeted by flyovers of a Swainson's Hawk and a Sharp-shinned Hawk . Perhaps the best sighting was a flock of Marbled Godwits flying over at the southwest corner of the dyke. In all we observed 60 species:

Pied-billed Grebe, Eared Grebe, Western Grebe, Clark's Grebe, American White Pelican, Double-crested Cormorant, Great Blue Heron, Great Egret, Snowy Egret, Black-crowned Night Heron, Canada Goose, Gadwall, Mallard, Cinnamon Teal, Northern Shoveler, Redhead, Osprey, Northern Harrier, Sharp-shinned Hawk, Swainson's Hawk, Red-tailed Hawk, American Kestral, Ring-necked Pheasant, American Coot, Sandhill Crane, Killdeer, Black-necked Stilt, American Avocet, Willet, Marbled Godwit, Long-billed Dowitcher, Franklin's Gull, California Gull, Caspian Tern, Eurasian Collared Dove, Mourning Dove, Western Kingbird, Black-billed Magpie, Tree Swallow, Northern Rough-winged Swallow, Barn Swallow, Black-capped Chickadee, Marsh Wren, Ruby-crowned Kinglet, American Robin, European Starling, Yellow Warbler, Yellow-rumped Warbler, Green- tailed Towhee, Brewer's Sparrow, Savannah Sparrow, Song Sparrow, White- crowned Sparrow, Red-winged Blackbird, Western Meadowlark, Yellow- headed Blackbird, Brewer's Blackbird, Great-tailed Grackle, Brown- headed Cowbird, and House Sparrow.

Those participating in the field trip were Lynn Garner (leader), Wade Miller, Milt Moody, Carol Nelson, DeLoy Pack, Ben Palmer, Leena Rogers, and Reed Stone. Lynn Garner

American Robin
by Bonnie Williams

This spring I have enjoyed watching one of our common birds.  Several years ago we planted a Flowering Crab Apple Tree outside of our kitchen window.  Until this year the only thing that took advantage of the All-you-Can-Eat Fruit Tree were the deer that could only reach part way up.  This spring the American Robin took advantage of our offer.  I have had dreams of looking out of the window and seeing it full of Waxwings (mixed flock of course) but no luck.  Maybe next year, but for now I will enjoy the good old American Robin, they have to eat just like us common people.
