Dr. Winsor M. Tyler contributes the following: "The orange-crowned
warbler is a rare bird in New England, but we may look for it with some
hope of success in the very late autumn, through November and even into
December, during the soft, calm days of Indian Summer. As we walk along
over the dead leaves, wet from last night's frost, watching for the bird
in the shrubs by the roadside and in neglected pastures, almost the
only sound is the ticking of the falling leaves as they hit against the
branches; and mistiness is all about us. Several seasons may pass before
we hear its sharp _chip_, which stands out clearly from the gentle voice
of the late-lingering myrtle warblers, and see it flitting all alone
among the twigs, or on the ground--a lonely, dark, obscure little bird,
darker and more deliberate than the kinglets. It is strange that a
_Vermivora_ should linger here with winter so near at hand, but indeed
there is evidence which leads us to believe that a few of these warblers
may attempt to spend the winter in the southern part of this region, and
should any one of them withstand the cold season, it may furnish, when
it moves northwards towards its breeding ground, one of the exceedingly
rare instances of the occurrence of the bird on the northern Atlantic
coast in spring."
_Winter._--The principal winter home of the orange-crowned warbler seems
to be in the southern Atlantic and Gulf States. Of its occurrence in
coastal South Carolina, Arthur T. Wayne (1910) writes:
My earliest date for its arrival is October 30, 1897, but it is never
abundant until the middle of November, remaining until the second week
in April. It is capable of enduring intense cold. I have seen numbers of
these highly interesting birds near Charleston when the thermometer
ranged as low as 8° above zero and it is always more active and hence
oftener seen when the weather is cold and cloudy.
The Orange-crowned Warbler inhabits thickets of lavender and myrtle
bushes as well as oak scrub, and its center of abundance is on the coast
islands, the greater part of which is veritable jungle, in which it
particularly delights. Its only note while it sojourns here is a _chip_
or _cheep_ which very closely resembles the note of the Field Sparrow in
winter.
Dr. Chapman (1907) says: "During the winter I have found the
Orange-crowned Warbler a not uncommon inhabitant of the live-oaks in
middle Florida where its sharp _chip_ soon becomes recognizable. In
Mississippi, at this season, Allison (MS.) says that 'its favorite
haunts are usually wooded yards or parks, where the evergreen live oak
and magnolia can be found; I have seen it most commonly among the small
trees on the border of rich mixed woods, above an undergrowth of switch
cane. Coniferous trees it seems not to care for, though I have seen it
in the cypress swamps.'"
