0n 1-24-08- on and off approx. 40 mins, 1-25-08-on/off 45
mins, 1-26-08 on/off for approx.1 hr.,20 mins, 1-27 for approx. 3-4 hours
total of aprx. 10 hours at site. |
Habitat: |
The surrounding terrain is level, with grasses, weeds of
various heights and rather open. The immediate site is a very short-grazed,
grassy cattle lot, muddy and very pock-marked by cattle use, also bordered by
two road edges and other fencelines/narrow shelterbelts bisecting lot of
Hackberry, Honey Locust, Chinese Tallow, scattered larger red-type oaks and
other mostly smaller trees. Fencelines also rank w/ low scrubby and vinaceous
vegetation, Smilax. Most all trees at site are deciduous, most lower
herbaceous vegetation and vines are either browned or entirely leafless.
There are 3 scattered buildings/sheds in immediate vicinity, one of which is
fallen down. |
Behavior of bird: |
The bird was first observed to ENE of my position in
middle of rd. in a low leafless tree at the SW corner of a cattle shed on
poles w/ no walls. The bird was observed for 2 seconds perched facing me,
faintly to side at approximately 5-6' feet on an outer limb, and
comparatively longish tail was noted with downward dip, deep but rather soft
like an EAPH, which I thought it was for first few seconds of observation, w/
distance and size deceptive at time w/ another bare bushy tree between myself
and bird, also noted was the pale grayish-green to crown. The bird sallied
(prob to ground) then re-appeared perched w/ more of side view and whitish
wingbars and tertial edging which were non-contrasting to palish remiges and
pale greenish back was noted. I said to Jeff, "I have a pale,
green-headed phoebe and it has white wingbars, THAT'S NOT RIGHT!" I
moved quickly to E, then N for a better look. After a very brief pause, bird
was relocated at ENE corner of barn and small size, pale sides to breast,
soft, complete eyering was noted and I said to Jeff, but certainly not
entirely convinced, "I believe we have a Gray Flycatcher. I noted the
dark blackish-gray upper mandible and yellowish, faintly orange-tinted
mandible below but could not see tip well. I also faintly saw the whitish
outer line/edge of rectrices when bird relocated. Jeff took some photos from
approx 80' when bird came closer and then handed me the camera as I went
under barbed-wire fence to try for a closer shot. I chased the bird for rest
of time and photo'd approx. 35 times. I was nervous, still in state of
shock/disbelief, but also was fairly sure I saw the dark and crisply
delineated tip to yellowish bill and thin white supraloral continuing across
top of bill through lens, when I was able to hold camera steady enough
(infrequently). The bird was heard giving soft dry "wit" calls. The
slightly-notched tail, w/ deep downward dip with none to faint lateral
movement, not stopped at bottom of dip and action continuous when returned to
original position and somewhat abruptly/stiffly stopped there, frequently
repeated at times- was also noted during this observation, further convincing
me it was GRFL. The bird was noted sallying to the ground often, w/ prey
items only secured/ swallowing noted only after leaving there. I also heard a
couple of emphatic, sweeter "whseew" calls. We called Jim Ingold
and others to notify. We continue atlasing further E on Deen Point Rd.
momentarily before deciding to go and check the photos. We stopped briefly on
way out and bird was relocated 100-+ yds to E. in open, short grass cattle
field w/ scattered weeds perched at 2', then disappearing low over taller
weeds to WNW. I suspected the bird would roost in dense tall grass and weedy
patch w/ scattered Baccharus Halimifolia 100 yds to N of immediate area.
Later, near evening Jeff and I found the bird again and followed. Jim Ingold
arrived and identified the bird, he also saw it crossing Deen rd. to S. Bird
foraged along slightly broader, more dense shelterbelt there briefly before returning
to cattle lot. Charlie Lyon arrived in very late afternoon and quickly said
"that's certainly a Gray Flycatcher" while observing bird perched
on low limb near NW corner of barn, and also followed and videoed/photo'd. It
was getting late and bird was still pretty far S near barn. I suspected at
this time that bird would roost in Smilax jumble at base of a few larger
trees to ENE of barn. The bird was relocated on following morning of 01-25
and followed- left notepad at home. Most all foraging sallies were noted to
ground, relocating and perching mostly low. Diagnostic video of tail action
and photos taken by several during morning observation. The bird was observed
taking rather largish prey items such as med.-sized black field crickets and
cutworms from ground. Hubert Hervey reported observing the bird arriving to
area from field across Wyche rd. to E. during his watch. The bird was
relocated on 01-26 at ENE of cattle shed by Devin Bosler at 07:52 am. It
captured a large prey item at 0756, noted by Devin (grub or cutworm) Justin
Bosler also heard "wseer" call while video-ing bird. The bird was
observed by many this day. I quietly arrived at 06:39 on 1-17-07 and stood
under pole shed 30' from Smilax thicket. The bird gave a barely audible "whseew"
call from Smilax jumble at 06:50, then again at 06:53, gave 2 "wit"
calls at 06:55, more at 06:57, then flew out to edge very close by and
perched at 4', then relocated unseen. Spotted at 3' again within thicket. It
moved back into open at 07:02 briefly with much "whit" calls. I
walked away but could still hear "wit" calls from 100 yards. When I
returned, bird was closer to rd. At 07:23 bird gave 2 low, dry, short and
snappy "ch'pddt" calls. Bird was noted sitting still once w/ no
tail action for approx. 2 mins. The bird appears well fed and looks like a
fat golf-ball with skinny tail- notably exaggeratedly when fluffing feathers
in response to cold, at which times flanks appear somewhat dingy due to
raised feathers. The bird was observed stretching and holding rectrices
fanned open and sunning on low limb when sun briefly peeked out afternoon of
1-27. It was also observed on different dates disappearing suddenly when any
of 2 LOSH flew nearby. Tail action did not seem as evident later in afternoon
as well, with shallower arc downward, more notable on upward flick and stiff
stop. I followed the bird somewhat off and on through day and showed others
around the area. Rosemary Seidler was there studying the bird when I left.
There were a few times when "wit" calls seemed a bit close and when
fairly-close sounding "wit" calls were heard when other observers
appeared to still be watching the bird a good distance away, but I believe it
to be extremely unlikely that another Empid is at the locality. |
Description:
|
Small passerine, small flycatcher, but large and
long-tailed compared to LEFL. The individual also appears pot-bellied and
well fed, whitish below w/ notably /pale-yellow-tinged belly,and only very
faintly darker at sides of breast. The flanks often appear dingier due to ruffled
feathers there. Above, the bird is a dull gray-green w/ slight grayer tinge
into sides of neck, often appearing grayer above in less available light. The
head is does not appear comparatively large like LEFL. Has notable thin,
whitish orbital ring, not blocky at front and back, more evenly rounded than
LEFL. Auriculars slightly paler, but like back, lores slightly darker,
thin/slightly broader white supraloral line continuing in thin line across
base of forehead above bill unlike DUFL. The folded wing has two white
wingbars, the lower slightly broader and appears to be faintly tinged w/
yellowish, but not seen well at times- possibly artifact of available light?
The tertials are also edged with white. The remiges/tertials/wing panels are
slightly darker than mantle, grayish, but rather pale gray compared to LEFL,
giving low contrast to wingbars and tertial edging. They also appear slightly
paler in primaries, and faintly brownish-tinged. The tail is comparatively
long, faintly flaring near tip and unlike straight/equal-sided edge of LEFL.
The tail also notably lightly notched. The tail above is approx. color of
back, and paler below, and dipped downward and returned to original position
frequently. The outer edge of rectrices show thin white line/edge mainly from
somewhat above tip to base. (action elim DUFL). The bill is comparatively
longish, narrow, orange-yellow below w/ fairly sharply delineated dark,
blackish, tip (elim. DUFL w/non-contrasty more diffuse dark tip) and slightly
paler blackish-gray above. |
Voice: |
Sporadically, the bird was noted to give fairly quick in
succession, short, soft, slightly sweet but dry "whit" or
"whsit" calls, most often notably having somewhat of "p"
sound- given as "pwhit" or "pswhit", but airiness and
sibilance mostly always were noted. I agree this call is also faintly 2-noted
as Mac Meyers suggested. I think it sounds much like LEFL but not repeated as
freq. The bird was also rarely on occasion heard giving high, emphatic,
notably tonal, and ascending-at-center "whseew" calls, somewhat
like ACFL calls but higher, and without notably more descending ending of
ACFL which often sounds somewhat like "whseehrr" or
"wee-hoo". Finally, the bird was observed giving 2 short, clipped
rather dry "ch'pddt" calls, but only on one occasion on time listed
in behavior above. |
Similar species: |
Least was overall eliminated by the comp. long tail and
action, less blocky eye-ring, paler remiges/less contrast, longer, narrower
bill w/ dark tip, and overall size. Dusky was eliminated by tail action, less
dingy at sides of upper breast, bill color/contrast below, by white edge to
tail, and by thin, whitish line across forehead. |
Photographs or tape recordings obtained? |
Photos were sent by Jeff Trahan. Charlie Lyon, Paul
Dickson, and the Boslers among others obtained photographic/video recordings
as well. |
Previous experience with this species: |
None, but have studied intensively at times in years past in case of remote possibility of one being found. |
Identification aids: |
Memory of Donna Dittman previously mentioning white-edged rectrices and tail action during previous fall was helpful- putting that first and foremost in memory during sighting. Briefly looked at Nat. Geo 2nd edition- which showed
almost exact back color of bird. Sibley, others have been helpful on Empids
ing general in past |
This description is
written from: |
notes taken during observation and memory |
Are you positive of your identification? If not,
explain: |
Yes. After having much opportunity of observing this bird, especially after tail action, I am also more-so convinced that at least 1 to 2 of birds found in early Nov. of previous year were probably DUFL. |
