Rosemary Seidler, Ronnie Maum, Willie Matthews,
12-06= Jeff Trahan
8. Other
observers who independently identified the bird(s):
9. Light
conditions (position of bird in relation to shade and to direction and amount
of light): 12/02- bird was initially observed at a bad sun angle to the East.
However, it was also observed to North, Northeast, then with a really good sun
angle to the West. 12/06= Cloudy- Bird was observed flying from North, then
overhead and perching in the pecan to our South.
10. Optical
equipment (type, power, condition): Brunton Eterna 11 x 45 binoculars in worn aesthetic but good
optical condition.
11. Distance to
bird(s): ~40 feet to ~75 yards
12. Duration of
observation: 12/02/12=30 minutes, 12/06/12= 5 minutes.
13. Habitat:
Older, open, grassy, somewhat hilly and manicured neighborhood with well-spaced
houses along a point jutting North from near the East end and on the South
shore of Caddo Lake. Larger trees spaced but somewhat closer along E Croom in the immediate viewing area. There are wide, open
grassy spaces with few trees North toward the point, Southeast between houses
and the road, then Southwest and West beyond Croom,
between there and the lake. Some houses and trees also spaced closer along
Ferry to the Northeast. Few large shrubs except last house on W side of Croom and some along Ferry
14. Behavior of
bird / circumstances of observation (flying, feeding, resting; include and stress habits used in identification; relate
events surrounding observation):
15. Description
(include only what was actually seen, not what "should" have been
seen; include if possible: total length/relative size compared to other
familiar species, body bulk, shape, proportions, bill,
eye, leg, and plumage characteristics. Stress features that separate it from
similar species): First off, our group was there only to confirm the identitiy of the bird, whether Couch's or Tropical. The
bird was actually found the previous day during the Caddo Lake Christmas Bird
Count- warm-up on 12/01-12 by Carolyn Phillips, Lily Poole, Martha Lennard and Shirley Huss
12/02= Medium-large kingbird with fairly long
but somewhat thick bill, bright yellow below in lower breast through belly,
whitish throat and sides of face and whitish-gray upper breast. Gray head with diffuse, somewhat broad darker mask through and
behind eye. Comparatively darker and grayish-green
back and comparatively darker wings with more contrasting paler edges to
feathers. Tail broader toward tip and forked when relaxed. When first
observed, the mantle of the bird looked grayer, more Tropical Kingbird-like.
However, the bill at the initial viewing angle looked shorter and thicker. The
tail also appeared equal width throughout length and squared at the tip. This,
also in combination with probability factor, at first had me leaning toward
Couch's. However, shortly after, the bird approached and vocalized in response
to TRKI playback. The tail was then also seen to appear both even and
square-tipped more like Couch's when the bird was more alert, then noticeably
wider toward the tip with a noticeable fork, as the bird relaxed. Pictures
taken on 12/02 also show that the bill is rather long and more like Tropical,
although it does appear comparatively a bit on the thick end for Tropical, in
my opinion. 12/06/ No additional plumage data- bird was observed flying and
perched but was silent
16. Voice:
12/02= The distinct, hard, rattling, somewhat
metallic, ascending "pit pit pr
tr'ti't't't't'teek" of Tropical Kingbird was
given, also recorded. This, with initial notes more spaced and level, then
rapid and ascending toward end. The "song" was rather loud. There
were also lower, more level and less-audible "pit" calls, with 1-3
notes heard given. Some of these were also recorded. Interestingly, the bird
only called in our experience on 12/02 during a warmer 73 degrees. As with some
winter residents that sing better on warmer or calmer mornings, the warmer
temps might've given the bird an additional hormonal boost- as it did not call
when observed again on 12/06, also was silent for most others when visiting.
17. Similar
species (include how they were eliminated by your observation): Couch's by
call, longer bill, noticeable fork in tail when
relaxed and somewhat by grayer, more washed-out and less green to back with
more contrasting, paler feather edging to coverts
18. Photographs
or tape recordings obtained? (by whom? attached?):
19. Previous
experience with this species: Seen and heard on several occasions during trip
to lower Rio Grande Valley in 2007. Other than that, quite
extensive study over the years of calls, shape and plumage versus Couch's.
