Field Marks and Identifying Characteristics: |
Sighting: Larry Tripp and I saw a female type Carpodacus finch at Lytle Ranch.
We heard a bird repeatedly giving a musical two-syllable call note from a box
elder along the main road north from the orchard. Neither of us was familiar
with this call, but before we could locate the bird it flew down into the
alfalfa field, about 10 feet from us. We walked towards the bird and it flushed
and flew across the field and perched (along with a bunch of sparrows) in a
large box elder on the west edge of the alfalfa field. It gave a single pick as
it flew out. Still not sure what the bird was, we eventually located it perched
in the tree, continuing to give it s two-note call and discovered it was finch
and quickly settled on a Purple Finch. We believe it was of the Pacific race,
due to an olive/yellowish wash on the head. The finch then flew off to the
south; we tracked it and thought it landed in the large mulberry tree in the
orchard, but could not relocate it when we made it down there. We spent awhile
listening for it s distinctive chu-weeh call, but could not relocate it. Before
it flew, we were able to get some views of the bird noting bill shape,
streaking, head pattern, etc., and apparently the pick call is diagnostic of
Purple Finch. Description: Larger and more robust than a House Finch, similiarly but more boldly marked. Upperparts with a buffy olive wash. Head round with large triangular bill, brown crown, pale white supercilium, brown auricular patch, dark eye with no eyering, pale malar, dark brown lateral throat stripe, pale throat. Back brownish, washed with olive, and darker streaks on middle of back, wings brown, tail brown and distinctly notched. Breast, sides, belly, and flanks densely streaked with long, broad, slightly blurry streaks; buffy pale background on upper breast gradually more white towards undertail coverts. Undertail coverts without obvious streaking. We did not note the primary length or any primary/ tertial edging. |
Song or call & method of delivery: |
We heard the bird repeatedly giving a musical two-syllable call note ( chu-weeh
) from a box elder along the main road north from the orchard. It gave a single
pick call in flight as it flushed from an alfalfa field. Larry and I were both unfamiliar with the perched call and the flight call; neither were anything we were familiar with in southwestern Utah. |
Behavior: | Calling from tree top, quick and direct flight down into an alfalfa field, flew up and across field and perched high in another tree, continued calling, then flew direct, high, and fast off down the wash at least for several hundred meters. |
Habitat: | Alfalfa fields, riparian vegetation (box elders, willows, ash, cottonwoods, etc.), orchard |
Similar
species and
how were they eliminated: |
Female/ first year male Cassin s Finch very similar but more distinctly brown
and white without olive wash to upperparts, with distinct streaking on
underparts shorter and more crisp, distinct eyering, usually dense streaking on
undertail coverts, and more prominently streaked back. Female / first year male House Finch superficially similar, but smaller with a slimmer body and longer tail, lacking obvious face pattern, and small bill with a obviously curved culmen. Perhaps the most important identifying characteristic we observed was the pick flight call, which is diagnostic of a Purple Finch (and no similar calls are given by any other Carpodacus finches). |
Previous
experience with this & similar species: |
I've observed all the North American Caropdacus finches many times. |
