The habits and movements of Bachman's Warbler are in some respects
peculiar and characteristic. It does not flit from twig to twig nor
launch out after flying insects in the manner of most Warblers, and many
of its motions are quite as deliberate as those of a Vireo. Alighting
near the end of a branch it creeps or sidles outward along a twig, and
bending forward until the head points nearly straight down, inserts the
bill among the terminal leaflets with a peculiar, slow, listless motion,
keeping it there a second or two, and repeating the leisurely thrust
many times in succession without changing its foothold. The action is
like that of several other members of the genus--notably _H. pinus_ and
_H. chrysoptera_--under similar conditions, and suggests the sucking in
of liquid food, perhaps honey or dew. Not infrequently a bird would hang
back downwards beneath a twig and feed from the under sides of the
leaves in the manner of a Titmouse. * * *
Many of the hackberry trees along the banks of this stream contained
compact bunches--nearly as large as a child's head--of dead leaves
blackened by exposure to wind and weather. These bunches probably
sheltered insects or their larvae, for they attracted several species
of birds, especially the Bachman's Warblers which would work at them
minutes at a time with loud rustling, sometimes burrowing in nearly
out of sight and sending the loosened leaves floating down to the
ground. Upon exhausting the supply of food or becoming tired of the
spot--whether one of the leaf bunches or the extremity of a cypress
branch--the bird almost invariably started on a long flight, often going
hundreds of yards through the woods or crossing the river, instead of
merely passing to the next branch or tree as almost any other Warbler
would have done under similar circumstances. This habit seemed to us
characteristic of the species.
