13.
Habitat:
1.
Inner-city/Urban, hilly pine-oak neighborhood near Centenary with many large
trees, lots of azalea, Camellia and other large shrubs, also overgrown alleyway
and thickets to the n and east.
2.
Dense Campsis/assorted vine-covered thicket adjacent
long, narrow seasonal pond with widely scattered small trees- surrounded by
thick grassy/weedy area with much goldenrod, dewberry, Johnson Grass, others.
3.
1-02-12 and 1-19-12 Fairly large opening within a
Large, somewhat hilly sandbar area between the river and the old river channel-
with clean soft, sandy substrate. There are smaller patches of younger black
and sandbar willows within the opening and larger, more mature, continuous
patches of willows around the edges. The sandy ground is now covered with
dewberry in places, also asters and various weeds and grasses at others-this
also spottily sparse in a few coarser sand areas. There are also a few
semi-mature eastern cottonwoods at higher centers. There were formerly much
more large sapling cottonwoods, box elder maple, etc,
within the immediate area but many were killed in flooding during 2006/07 and
are now lying as deadfalls and enormous logjams peppered throughout the area,
some extensive and could prove dangerous in traversing.
4.
Overgrown parcel/former homesite. Viny,
dense "green" thicket- predominately Ligustrum
with a few larger hackberries and pecans, also scattered other smaller deciduos trees. Very thick along the
edge. Entirely surrounded on all sides (except
railroad and hwy 1 to east, which is also quite
open/orchard-like) by fallow open agricultural/plowed fields. The strip
also continues narrowly to the west
14.
Behavior of bird / circumstances of observation (flying, feeding, resting; include and stress habits used in identification; relate
events surrounding observation):
1.
The call appeared to be emanating from a dense thicket of azaleas- other
sparrows present nearby were, in order of abundance, White-throated, Lincoln's,
Swamp and Song. I did not have bins or i-pod handy
and was busy with work except during the brief, quiet moment near the azalea
patch
2.
The bird was very furtive in terms of sight, only seen well perched up still
for a short period of time in which Jeff Photographed it. The bird appeared by
sound to be moving for a good distance back and forth along the pond- approx 75 yards or more- by voice, while we were looking
for it. It frequently called in response to playback but often remained silent
for periods of time as well. Other sparrows nearby were mostly White-throated,
Song, Swamp and Lincoln's.
3.
1-02-12 This bird was also quite furtive but actually
easier to see than the previous Yates Tract bird on the first occasion. It rose
into a small thick patch of willows and perched up at about 6-8 feet in the sun
for my first observation- then began frequently calling after I used playback.
It was observed for several minutes there and seen briefly after relocating
farther away. 1-19-12 with Jeff, the bird was first heard calling, then
observed moving to the southwest with/near a gp of
Field Sparrows and American Goldfinches, then observed perched low at close
range on a low limb of an eastern cottonwood approx
3' from the ground. It was on the opposite side of the tree from us with the
narrow trunk partially hiding the bird for a short time, then
quickly relocated to northwest on top of a small stump perched openly, briefly
before relocating low and unseen. Other Sparrows present in order of abundance
on 1-02-12 were White-throated, Field, Song, Savannah and Swamp, on 1-19-12 the
order was Field Sparrow, American Goldfinch, White-throated and Song.
4.
2-07-12 The bird was very furtive and appeared to be
silent after playback, then calling a few minutes after playback had been
discontinued. It was heard giving a high pitched twittering during playback
once. Other sparrows in immediate vicinity were White-throated and Fox.
White-crowned Sparrows began approaching thereafter from 100+ feet across an
open area from the southeast but only a while after Eastern Screech-Owl tape
had being used.
Interestingly,
none of the birds found in nw
La have been with White-crowned Sparrows- as has often been reported from
farther south this season. However, some sparrows in general- especially
White-crowned, have been notably low in our area in their usual, more open
haunts this season along the Red River valley open agri-areas.
Many of these areas that White-crowned generally frequents were extremely
hard-hit by the previous drought. Although some counts in 2007 and 2008 were
especially high with 650 to 700+ indivs, they have been
exceptionally low in these same areas, with 30-40 indivs
being an excellent count. Then again, some areas, such as where water has been
being pumped since late summer, such as Red River National Wildlife Refuge,
Bayou Pierre Unit- Yates tract, have had comparably good nos
than before- although again, Green-taileds were not
found in close proximity to them during any of my personal observations.
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): The
two separate individs that were actually seen were
hatch-year birds, as Clyde Massey had first mentioned about the Yates bird. The
first obvious thing I noted during the 3 sight records of two separate indivs was the crisp, white distinct "5-way"
throat, supraloral and submoustachial pattern on a
dark, but quite clean gray face and dark malar, dusky forehead and warm,
somewhat palish rufescent
crown. They were small, short-tailed towhees, medium-dark-gray below and very
much gray in mantle with little to no green there. The tails and wings showed
green well but it was notably more obscure there than would be on an adult indiv.
16.
Voice:
1.
10-30-11. A two-noted low, very nasal, almost unbird-like
"mee-ee!" or "meewee"-
this rising on second note I had
originally decided not to send this date record in due to basis of but a single
call. However, three things prompted a change of heart thereafter, No 1- The
bird began being reported frequently in areas to the south shortly thereafter.
No 2.The call was heard extremely clearly, sounded fairly close-by and winds
were calm there at the time 3. No mimicry by other species had been going on at
the time.
2.
11-12-11. Indiv was heard giving ascending "mee-ee" calls for the most part. It was also heard
giving a rapid, high and thin twittering- "sweetititititit',
or "sweeteeteeteeteeteet" much like an indiv call in Stoke's collective .
3.
1-02-12 and 1-19-12. Indiv was heard giving "mee-ee" calls, also a short, rapid trill with abrupt
beginning and ending, this without example that I've heard thus far on taped recordings,
although it may well exist. The call sounds somewhat like a call given by
Spotted Towhee on Stokes except that it is much thinner, less buzzy and more
sibilant. I would phoneticize, then write the call as
"khweeee!", although it would be hard to
place the noted sibilance in doing so-"maybe"squeeee!",
but the call does not begin with sibilance/ Place sibilance within the e's. The
indiv was heard giving both "meewee"
and "khweeee" calls on both dates.
4.
2-07-12- Indiv was heard giving a string of 7 or so
slightly separated "meewee" calls, then two
other separate calls about a minute apart afterward. It was also heard giving
the high-pitched twittering as heard on Stokes.
17.
Similar species (include how they were eliminated by your observation):
White-throated sparrow facial appearance bears a vague reminiscence in pattern
but totally different when seen well, as the above observed indivs
were, and lacking rufescent crown. The closest call
that comes to mind for the "meewee" call is
Yellow-bellied Sapsucker, which nearly always descends and not so nasal. The
twittering call can be somewhat closely approximated by some other local spp but was distinct when hearing it as well. The short,
rapid trill was distinct. Similar call of Spotted in Stoke's
collective approximates, but Green-tailed's sounds
much less buzzy.
18.
Photographs or tape recordings obtained? (by whom?
attached?): Jeff has sent pics of the Yates tract
individual
19.
Previous experience with this species: Brief looks at an adult indiv in early April of 2000 a considerable distance northwest
of Choke Canyon in Texas. Frequent study of plumage and vocalizations from time
to time from before then and afterward
20.
Identification aids: (list books, illustrations, other birders, etc. used in
identification):
a. at time of observation:
b. after observation: I mentioned
to Jeff while observing the Yates Tract bird that the green of back and tail
was quite obscured, the mantle being mostly gray, but had grown a little rusty
and did not make the aging connection at the time- and didn't look closely at
any field guides immediately afterward. Clyde Massey mentioned shortly
thereafter that the bird appeared to be a hatch-year bird by these
distinctions. The lock 5 bird was also "washed-out" in appearance in
this respect.
