Field Marks and Identifying Characteristics: |
This medium-sized flycather was dark gray above and whitish below. The tail was medium to long in length. The face was slighly darker, almost black, with an abrupt change to white below the eye. The head was relatively rounded on top. There were no wing bars on the dark wings. The undersides from the lower face through the throat, belly and undertail coverts were white, and when seen from the side and below a darker, but thinly colored "vest" was ovserved on the breast, nearly separated in the middle of the breast. The tail was dark both above and below, and while the bird was perched, it was nearly constantly flicked downward, then back up (phoebe-like). The bill was all dark, appearing black. |
Song or call & method of delivery: | none |
Behavior: | The bird was initially seen perched on a fence; The bird flushed several times and flew to nearby shrubs and two trees. The bird constantly flicked its tail while perched. |
Habitat: | The fence where initially observed bordered a path along a canal (contained some water) on one side and an open pasture on the other side. There were some cottonwood trees on the opposite side of the canal with open land beyond. |
Similar
species and
how were they eliminated: |
Other Phoebes: Two other phoebe species are found in Utah, black and Say's. Both
have tail flicking as seen in this bird, but their color patterns are much
different. Black phoebe has a jet black back, head and breast with white only on
the belly. Say's phoebe has extensive dark tawny color in the belly and a
grayish breast and throat. Empidonax flycatchers: This bird lacked an eye ring and wing bars found on these species. Also, the abrupt color break on the lower face from near black to white is not found in these flycathers. None (except gray) of these flycatchers are known to constantly flick their tail downward. Western (and eastern) wood-pewee: These birds are a bit greener in color, don't have the abrupt color break on the lower face, have a pale lower mandible, can have a peaked appearance to the back of their head, and don't constantly flick their tails downward. Olive-sided flycatcher: This species appears a bit greener, does not have the abrupt color break on the lower face, has a much more extensive "vest" on the breast, has a much shorter tail, has a peaked appearance to the back of the head, and does not constantly flick its tail downward. |
Previous
experience with this & similar species: |
I have seen many Eastern phoebes in the eastern US (particularly Michigan). I have also recorded one in Logan, UT in April, 1983. |
