Behavior of bird: |
Bird was first observed on 11-27 flying to ene. Jeff and I
near simultaneously spotted the bird. He, with a slight jump on me, exclaimed
how yellow below bird appeared. I had brief looks at the bird going away at a
bad light angle. I noted the pale tail and said it looks CO/TR but could yet
possibly be a Weki due to bad light. We relocated bird a few minutes later in
top of large cottonwood approx 800 yds to ene, next to a small metal
building. Jeff Trahan photo'd w 100 mm and then returned to vehicle for
larger lens. I stayed on bird. Shortly before Jeff's return, bird relocated
75 yards to ene to top of another large/ mostly dead dead cottonwood. Jeff
returned and photo'd bird which relocated again to E/S into the top of a
fairly large flat-topped Hackberry. He was able to get more photos before the
bird flew again to ene and disappeared within edge of woods bordering
neighborhood. Everything I had seen about the bird looked Couch's up until
this moment-other than small size. I indicated to Jeff I thought it was a
Couch's 2. On 11-28, I observed the bird from 1100-05 along fenceline between
ponds and high field- about same spot as we first saw bird. It was sallying
at a lower level of 20-+ feet using near leafless Black? Mulberry for perch.
In same area on 11-29,from 1115-20. Seen on 12-01, it was farther toward
river to w/wsw at hedge of deeper woods, and higher in larger Black Mulberry.
On 12-03- W/Jack Land, the bird was called in with i-pod to large hackberry
within 30yds yds of 11-28,29 sightings. The bird acted very territorial in
response to the i-pod call duplication. We did not continue to play the call
or further harass bird |
Description:
|
On days when all details seen really well- The bird is a
large flycatcher/ med. large kingbird.It does look smallish for the species
and definitely smaller than individual(s) seen on 08-08,15, and 09-11-07 The
dark bill appears proportionately short and rather thick, with lower mandible
somewhat convex as upper. The tail is paleish w/ non-contrasting edges or
tip, appears parallel-edged and proportionately short w/ a sqare tip, or
faintly double rounded/convex double-tipped appearance w/ faint notched
center. The bird was bright yellow below from undertail coverts to
upper-chest, slightly paler yellow there and grading into a grayish white
upper chest and throat. The cheeks below eye slighly brighter white w/ dark
grayish/pale blackish masked appearance at rear of eye. The crown was med. pale-grayish.
The mantle is yellow-green and brighter than the wings which were grayer,
wingbars very faint, non contrasting overall to rest of wings. |
Voice: |
On 12-03-07 w/ Jack Land= Excited string of snappy, rich,
high and level, to slightly ascending hard "pip" calls and
"pip-preer" call with "preer" portion lower and sounding
cleanly burry w/"metallicly-trilled" quality. The "preer"
call slighly ascends and then descends. The "preer" call also heard
by itself, uttered slightly less audibly 1-2 times |
Similar species: |
Tropical Kingbird- eliminated by voice, less so by bill
and tail structure/ shape and plumage morphologyWestern Kingbird- by voice
and more upward extension of yellow below. By tail which was pale and
non-contrasty (vs dark w/ thin white outer edges) |
Photographs or tape recordings obtained? |
Photos will be provided by Jeff Trahan and possibly Jack
Land. |
Previous experience with this species: |
In years past I observed several individuals at different
areas between Choke Canyon and RGV in Texas. There was a Couch's observed at
this same locality in Nov of 2006. Have studied the species somewhat
extensively in past 3 years. |
