Behavior of bird: |
At
first only a single adult was observed foraging fairly low over the lawn on
the east side of the bathhouse. Noticeable
upon initial glimpse was an in flight jizz and flight style inconsistent w/
the expected Tree Swallow. Within
minutes, a second adult joined the first bird in foraging in typical
swallow-like fashion around the bathhouse.
Both swallows were last observed foraging over a broader area to the
east of the bathhouse. |
Description: |
Compact,
square-tailed swallow w/ rufous-orange rump, dark bluish back w/ distinct
longitudinal white streaks, dark brown wings, and pale orange-buff collar
separating dark bluish back and dark cap.
Cheeks, sides of neck, and throat were orange-buff and contrasted
markedly w/ dark rusty forehead patch and whitish belly. Sides were tinged grayish. Undertail coverts with dusky/dark brown
centers. Presumed P. f. pelodoma
based on size, relative paleness of orange cheeks/throat/upper breast, lack
of throat/upper breast color bleeding onto sides, and date of occurrence. |
Voice: |
not
heard. |
Similar
species: |
Cliff
Swallow (CLSW) eliminated by orange-buff cheeks, sides of neck, and throat in
combination w/ dark rusty forehead patch.
Melanogaster CLSW w/ cheeks and throat similar to nominate, but
w/ rusty or chestnut forehead. Other
swallow spp. easily eliminated by tail and wing shape, plumage coloration,
and flight style. Hybrid Cave x Barn
ruled out by relatively short, squared tail and typical adult CASW plumage. |
