pale throat cross-band to an black median streak to
a black cross band and throat. Had much trouble
associating the 2s of all this species.
(23) Seedcater - the commonest species here,
in small flocks out in the pears and singing from all
heights, 1ft to tree top. Absent only in the heavily
forested areas, but present on the edges. It seems to be
fairly variable, or I am confusing it with another green;
there is a light and a heavy streaked (on the breast) ? here.
See species # 22 which may be the same, in another
plumage. The song is quite variable, and more usually
given from a perch. It seems to be the only "fiddle" song
here, except for this confusing ones. The flight song
is a longer, lighter version of the perched song.
(23) Very variable. This is the black finch I took
yesterday, and is extending variable as to the plumage
it sings in. It varies from a brown bird, with a tinge of
blue on the breast, to a black-breasted, brown backed,
to a blue-black bird with white mottling on its
belly, to a solid blue-black finch. Bird black.
When in a flush, singing it jumps leap about 6-10
inches, does a somersault, and returns to the same
perch. When on top it stays perched, usually. Song
is a buzzy "p.t birdleowzz",
c. 3/4 second long. F is brown
and drewwly streaked on the breast. I prob. confuse
it with the above fairly often. It is far common in much
the same situation, but more evenly and widely
