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): 11/21= The bird was unknowingly photographed
in good afternoon light with the light behind us, although most of the photos
are shaded by limbs or out of focus/blurry, etc. 11/23= Good amount of video
was taken at close range under brigh overcast
conditions. 12/01= Briefly heard. Jay saw the bird in
good light to our Southwest around 10:20. 12/15= Bird observed to South and
West, mostly perching low with sun overhead, alternating briefly cloudy and
sunny- but mostly in rather good light and angle. 12/24= Observed during sunny
weather and at a good sun angle from open and exposed in fairly open canopy
situations, to well-concealed within closed canopy. 12/30= heard only
10. Optical equipment (type, power, condition): Brunton Eterna 11 x 45 binoculars
in worn aesthetic but good optical condition used during personal viewing
11. Distance to bird(s): From 10' up to 100+ feet on
different dates.
12. Duration of observation: 11/21/12= For
a few minutes while photographing. The Ash-throated was observed for a longer
period just prior to that. 11/23= Off and on for 30+ minutes. 12/01= A few
calls heard off and on for ~40 minutes, brief view by Jay, 12/15= For 35
minutes on and off, much of that with bird rather closely or somewhat in view
while we observed and Ronnie photoed. 12/24= On and off for nearly two hours. The bird was first heard
shortly after 0700, then not heard for quite some time. It was heard again
shortly before 0800, then observed around 0800, from then until we left at
around 1000. 12/30=Heard only briefly slightly over mid-way between 10 and noon
during the survey.
13. Habitat: Observed in baldcypress
and on dead outer branches of vine-covered shrubbery forming dense thickets
near water's edge. This is backed by slightly more open hackberry/mix woods
with grassy understory, scattered clups of
small-leaved Ligustrum (L sinensis-
privet) and numerous downed trees or branches. On 12/30, the bird was
heard-only, approximately 100 yards N of where it was viewed on previous
occasions. This area is rather thick with large, bushy-based Eastern red cedars
and much fewer deciduous trees. There is a faitly
profuse understory of wiry grasses. The area also has fewer dead or downed
trees or branches/brushpiles on the ground, except
along the edges near the main road.
14. Behavior of bird / circumstances of observation (flying,
feeding, resting; include and stress habits used in identification; relate
events surrounding observation): On the afternoon of 11/21/12, we re-found a
definite Ash-throated Flycatcher which was perched in the same baldcypress in which the Dusky-capped was unknowingly
photographed moments afterward. We observed from close range, noting it's overall noticeably larger size in comparison to E
Phoebe close by, the pale-pinkish-based and comparatively stocky bill and diffuse
dark line that extended well across the tip of the rufous tail. We also heard
it plainly between short breaks of E Sreech-Owl and
Ash-throated Playback giving the distinct ATFL short, soft "prrt" or "bic"
calls and head-bobbing a few times in response to ESOW and ATFL playback. We
observed it for several minutes before getting an infrequently-used camera out
to try for photos. I spent some time fiddling with the camera and did not look
again with bins, except briefly at the bird that was present when we looked
back up, to relocate it when it moved as I photoed.
Charlie was making some adjustments in the boat, occasionally looking back up
to help relocate, as I photoed the bird. We
immediately left once a few photos taken were briefly looked at, thinking we'd
had about as good as we could get. Later, we uploaded
and looked briefly at the pics on the computer but
were in a hurry, due to the late time, to look once again at what we'd obtained
of the Pacific Loon. We noticed that the bill of the flycatcher looked really
dark and that the tail did not show any rufous. I failed to note the brighter
yellowish belly and plainer wing panel at this time. In our defense, the photos
weren't of very good quality and quite blurry. Moreover, WHO in their right
minds would've thought that a Dusky-capped Flycatcher would be present in the
exact same tree immediately after getting good looks at a definite Ash-throated
there!!? Again, in our haste to review the loon photos once more, we didn't
think much more about it at that time. 2. 11/23/12= We
returned to the spot with Hubert and began looking for the bird. Activity with
other passerines was quite slow at the immediate area- as during the previous
observation, with exception of an ever-present E Phoebe, a few AMGO and calling
WIWR and WTSP in the thickets and woods to the East. It took a few minutes to
bring the bird in. At about the time that the definite Ash-throated was being
observed in the baldcypress, the Dusky-capped was
also then plainly heard giving it's distinct, mournful,
descending "wheer" call nearby and it's identity was suspected. It was heard on a couple of
closely-spaced occasions and thought to be confirmed shortly after that. While
we observed the larger Ash-throated on a North-facing branch of the baldcypress, the noticeably smaller Dusky-capped was
observed arriving into the South side of the tree from the thicket to the East,
prompting the ATFL to very quickly relocate briefly North, then back East
toward the denser thickets. Charlie obtained video of the Dusky-capped at very
close range as it bobbed and occasionally called, although this was hard to
hear at the time with playback running. Each time playback was briefly shut off, the bird would retreat into the thicket, only to be
heard occasionally calling, then only return or relocate nearby once ESOW or
DCFL playback was once again used. Diagnostic field marks were observed during
the observation, also afterward when looking at the video. 12/01= Bird was
furtive, heard only regarding personal detection, then
briefly seen by Jay.
12/15= Bird was observed at on and off at close range for 35
minutes and often perched on horizontal twigs rather low or slightly above, but
more often at or below eye level. Playback of ATFL and DCFL was only briefly
used. The bird did not respond to this. Brief Eastern Screech-Owl brough the bird in, bobbing and calling very closely,
within 20-30 feet of Ronnie and I. Once, it relocated North just 10 feet West of us, touching down for a brief
second on a low branch 2' above the ground, before relocating back West. It was
particularly adept at partially or totally obscuring itself behind adjacent
branches during the entire time we observed. It remained in the general area,
occasionally sallying and was still there when we left.
12/24= The bird was heard calling
on numerous occasions on and off during our observation. There were at least 3
observers, including myself that again thought it might be possible that there
were more than one DCFL present, due to calls heard distantly from a different
direction as the bird was being closely observed. The bird also bobbed it's head fairly frequently in response to an unheard or
unseen stimuli (this often well before or after any brief playback had been
used), then fly off toward that direction. There was one occasion when the bird
was being closely observed when I was near 100% sure another bird called to our
right. The visible individual was being watched at that time and not seen to
call. It also bobed vigorously
after the call of the other bird and briefly relocated. However, the
single individual that has been observed during visits to the site, does show a
penchance for the head-bobbing behavior- and brief
playback had been used on a few occasions this day. Overall, though, the
possibility of two birds calling in different directions noted this day seemed
very uncanny- I was all but convinced there were two birds, if subtracting the
improbability factor, during the aforementioned incident. Personally, the
behavior seemed very sprite in comparison to what I've observed with Great
Crested, and to a much lesser extent with Ash-throated. The bird was on the
move, sallying and calling more frequently than the notably more retiring and
quiet experiences I've had with ATFL and GCFL.
12/25= Very furtive and heard only, although we searched and
came up empty-handed for at least 45 minutes after hearing it. Pending LBRC
acceptance of this Dusky-capped Flycatcher, it would be a first for
Louisiana.
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):
11/21/= Photos taken on this date, once again reviewed in retrospect, seem to
show overall proportions correct, also proportionately long, narrow and dark
bill, bright yellow belly and lack of rufous in tail distinctive of
Dusky-capped Flycatcher. 11/23= The descending "wheer"
calls were heard, also on a couple of occasions there sounded as if there were
possibly a more distant bird answering back with calls, although this may be
attributable to the bird varying the volume of it's
voice. There were at least two calls that were given in a very short space of
time, though. A more distant, softer than GCFL, ascending "weep" was
also heard, along with a descending bickering trill. The bird was first seen
flying into the tree and was noticeably smaller than the Ash-throated which
simultaneously fled, relocating away, then back into the woods. Although
somewhat pot-bellied and short-tailed when sitting, it looked distinctly small
and noticeably comparatively slender while in flight. The rufous wing panel in
secondaries was observed when the bird was not obscured or well-shaded by
branches on a couple of occasions, although this did not stick out extremely
well during the observation. The indistinct wingbars and lack of rufous in the
tail did. The bill was again seen to be all dark and proportionately long and
narrow in relation to the head. The bird bobbed frequently to both Ash-throated
and Dusky-capped playback, also came closer to E Screech-OWL, but quickly
relocated East toward the woods once various playback
being used were entirely shut off. There was also at least one instance when
observing the bird in a lower thicket to the Northeast when I was nearly 100%
sure that I noticed another very small Myiarchus fly in simultaneously as the
Dusky-capped being viewed, then it flew around toward the back side of the
vine-covered shrub and disappeared. I was absolutely sure it was not the E
Phoebe, which was a probable hy with a yellowish
belly, while making this observation at this time. However, after spending
quite some time in the field and realizing that things aren't always as they
appear- and epsecially with observation being brief,
it is very possible that I was mistaken. Voice recordings were made with an
I-phone that retained three audible exapmples of the
descending "wheer" call. 12-01= I heard the
bird give a few low calls shortly after entering the woods. Jay also briefly
had the bird in sight in a large leafless tree a little over a hundred feet to
the Southwest of our observation point, which was also in good light at the
time. Edit- 12/15= My best look at plumage
characteristics yet. The rufous secondaries were seen well and also captured in
photos. The tertial edgings were actually very
contrastingly whitish in contrast to the darker centers of those feathers and
to the rest of wing panel. I did not note this well during previous
observations, although it does show very well in some previous photos and
video. The comparatively somewhat brighter yellow belly versus Ash-throated, was also notable during this visit. Also noted the lack of diffuse, thin grayish area above the eye as
in Ash-throated, also the much noticeably darker auriculars/face. That
and the crown appeared notably browner than Ash-throated. 12/24= Excellent
views of the shape, size and plumage characteristics were again observed off
and on for well over an hour. The following was previously noted from earlier photos, then again in the field- The bill was again noted to
be pale at the base of the lower mandible. However, this looked dark from the
side view, unlike Ash-throated, which also showed this better than DCFL from
side views as well.
16. Voice: 11/23= The bird was
heard giving the distinctive low, mournful, descending "wheer" or "peer" of Dusky-capped Flycatcher.
We were also able to record this on a phone. There was also a
Great-crested-like ascending "wheep"
possibly heard once or twice, along with a comparatively soft and more rapid
bickering trill that somewhat descended toward the end- some of the latter
possibly attributable to playback response. This is what confirmed the presence
of the bird early on before we had good looks at it. 12/01= Heard giving
descending "wheer" twice, then a more
distant but fairly clear, ascending "wheep"
right before leaving. 12/15= Four descending "wheer"
calls were given, one while the bird was within 25' of us, but no recordings of
this were obtained. 12/24= The bird was heard giving
"wheer" calls many times on and off during
the observation. I also heard a trill descending at end on at least two
occasions. Occasionally the "wheer" would
sound more emphatic/excited and ascending before descending. A recording was
made of at least one of these more emphatic calls. 12/30= 4 to 5 descending
"wheer" calls which seemed to originate
somewhat more distantly from our location were clearly heard a little after
midway during the survey, although the bird was not found.
17. Similar species (include how they were eliminated by
your observation): From Ash-throated by calls, distinctly smaller size,
slimmer, darker and proportionately longer bill, darker face/auriculars,
lacking diffuse subtle grayish line above eye, notable lack of rufescent in proportionately shorter tail and plainer wing
panels with non-contrasting wingbars, rufous in primaries, also continuing into
secondaries in folded wing when sitting. Brighter, more
lemon-yellow lower belly than pale, washed-out yellow of Ash-throated.
18. Photographs or tape recordings obtained? (by whom? attached?): 11/21= Crappy photos were obtained.
11/23= Good/close Video by Charlie showing excellent behavioral response to
playback, bright belly and overall proportions for Dusky-capped well . 12/15= A few good photos were obtained by Ronnie Maum, also showing rufous in secondaries rather well.
12/24= diagnostic photos were obtained by more than one observer this day.
19. Previous experience with this species:20.
Identification aids: (list books, illustrations, other birders, etc. used in
identification):
a. at time of observation: During
the initial observation, zero experience personally, other than being familiar
with call, smaller size, plain wing panel and lack of rufous in tail. National
Geographic and Sibley were referred to on 11/23
b. after observation: Many photos and various texts were
studied to refresh on plumage detail in days shortly afterward.
