Powershot SD1100 IS (all equipment in
good condition) |
Distance to
bird(s): |
ca. 6-8 meters |
Duration of
observation: |
only in view for 1-2 min. over 15 min. observation |
Habitat: |
Upland mixed pine-hardwood regenerating clearcut, 10-15 years old. Primarily slash pine and white/post
oaks. Early successional brushy edge
along roadside with privet-sumac-dewberry thickets and greenbrier-honeysuckle
tangles. |
Behavior of bird: |
The towhee was
observed in flight and at rest. The
bird first appeared low in a dense thicket of Chinese privet, sumac, and
dewberry with accompanying Eastern Towhees.
It was coming in closer to investigate the screech-owl tape
recording. As expected, the bird was
agitated but remained silent. It would
fly into a dense patch of vegetation and perch quietly for a minute or two
before moving to another secluded spot.
It only perched in full view once or twice, but was always obstructed
by tangles, branches, or leaves. A
very territorial Northern Mockingbird was chasing off every towhee that
popped up. |
Description: |
A large, bulky
sparrow with a long, rounded tail.
Resembles Eastern Towhee in appearance with black upperparts,
orange-rufous sides, flanks and undertail coverts, and white belly. Entirely black hood and bib indicate adult
male. Long, rounded tail showing
extensive white corners underneath.
Fairly extensive white spotting on back including scapulars, upperwing
coverts, and tertials. Noticeable
white tips on median and greater wing coverts forming two superficial wing
bars. Dark slate-gray bill, paler at
base of lower mandible and reddish iridies.
Flesh-pink tarsi and feet. |
Voice: |
No song or calls
heard from SPTO. |
Similar
species: |
Eastern Towhee (EATO) can be eliminated by extensive white spotting on
scapulars, upperwing coverts, and tertials.
Also lacking white patch at base of primaries, a field mark consistent
with EATO. A hybrid can be safely
ruled out by the amount of white spotting on the back, especially scapulars,
which is unlike the intermediate characteristics shown by hybrids. |
