On Thursday, 18 January 2001, Rusty Trump
and I visited Debbie and Colin Grimes' farm in southern Brooks Co., GA, to
observe and photograph a Myiarchus flycatcher that had been
initially located by Duane and Debbie Kelsey, and subsequently by Debbie Grimes, around 9 January 2001.
Since Georgia has no verifiable records of
any Myiarchus flycatcher other than the Great Crested Flycatcher (Myiarchus
crinitus), a common summer resident throughout the state, it was
important to at least get photographs of the bird and to submit a report
to the Georgia Ornithological Society's Checklist and Records Committee
for review. There are two previous reports of Ash-throated
Flycatcher (Myiarchus cinerascens) in the state, but neither has
been documented to my knowledge. This is most likely the first
verifiable record for Georgia for this species.
The bird had most often been observed in
the afternoon by Debbie and Diane along a fence row at the edge of a pine
plantation that bordered a large overgrown field. After a failed
attempt at locating the bird along this fence row on the morning of 18
January, Rusty and I literally almost stumbled on it while making our way
across this field and its waist-high vegetation to another fence row on the opposite side of the
field. We watched the bird for approximately 1 3/4 hours, and for
the majority of the time, it stayed low in the weeds in the field, no more
than 6 - 8 inches off of the ground. On several instances, it
successfully nabbed several large invertebrates, including grasshoppers
and moths. Occasionally, the bird would
fly overhead and perch at the edge of a small "island" of trees
in the middle of the field for a short period of time (five -
fifteen minutes), then return
to the field to feed.
During one instance, the Ash-throated
Flycatcher chased an Eastern Phoebe (Sayornis phoebe), which was
also patrolling the wooded edges. It appeared to be noticeably
larger than the phoebe during these periods of interaction.
The bird was initially identified as an
Ash-throated Flycatcher by Debbie Grimes. After Rusty and I observed
the bird, we concurred, based on several characteristics that this bird
exhibited. There are some plumage caveats, however. Because of
these caveats, namely the undertail pattern and secondary edging
coloration, we feel that this particular individual was exhibiting some
retained juvenile characteristics (thus, an after hatch year bird).
Molt timing is obviously an issue if this was to be an after-hatch year
bird.
General Description
- Slim looking, with a well-proportioned head and bill;
- Pale gray sides of breast, whitish throat, and pale, creamy yellow
belly, lower breast and vent;
- Somewhat darker gray auriculars and
nape, contrasting well with the brown head and crown;
- Brownish to brownish-gray above above
(depending on the light), with darker wings broadly edged with an
off-white on the coverts, tertials and some secondaries;
- Some secondary edges appeared whitish,
while others appeared to have a distinct pale rufous (or perhaps
reddish-buff) coloration; this is particularly noticeable in the
first,
fourth and fifth scans. The whitish coloration appears to be characteristic of an
adult Ash-throated, while the pale rufous may be an artifact of
juvenile plumage;
- Primaries richly edged with rufous,
especially towards the base of the primaries;
- Bill entirely black; gape was closest to a dull yellow-peach
color (note the pinkish growth at the base of bill on the left side of
the head in the first scan);
- Rufous underside of retrices, with dark
brown/black outer tail margins that
fanned inward at the tip of the retrices (except the central retrices).
Many people have asked about the pattern, as Ash-throateds have a diagnostic undertail pattern when in adult plumage. Rusty, Debbie and I had an opportunity to observe the undertail pattern through a scope. I can say
with certainty that this bird did not have the dark tip of the tail that
would be expected of an adult Ash-throated Flycatcher. However, the pattern did fit that of a bird that is still showing some juvenile
characteristics. This pattern may be observed in the second
scan. I can also say that the tail did not appear to fold
properly (as may be seen in the first scan), and could possibly have been missing a feather or two, which
may support the age theory.
- The call notes that Rusty and I noted were similar to those described
in the field guides, and it is almost impossible to describe them accurately; the notes were a rather soft "pip" or
"pik", and a short,
burry "pert". Although the calls were somewhat soft (given how raucous
this genus of flycatchers can be), they stood out amongst the scads of
"seets" given by the unbelievable number of Savannah Sparrows in
Debbie's yard.
