This note appears to be identical in the eastern dowitcher and the
long-billed race which I have studied in Florida. Other minor calls
of the dowitcher are single, unloud, low-pitched _chups_ with which
a flock manoeuvred about decoys (Long Island, August) resembling an
analogous yellowleg note; a low rattle when dropping down to alight
(Long Island, May); a mellow, ploverlike _cluee_, suggesting a call
of single lesser yellow-legs when loath to leave a feeding ground,
calling to other more restless individuals of their kind. This was
heard from a single dowitcher on the ground when a flock of lesser
yellow-legs was flushed a little way off. When these departed it
took wing with more usual dowitcher calls and followed after (Long
Island, July). I have on record also a startled _chee_ from an
extra tame long-billed dowitcher in Florida, flushed by being
almost struck by something thrown at it.
While observing the shore bird migration on the coast of New Jersey,
during the last week of May, with Dr. Harry C. Oberholser, we frequently
heard the pretty and vivacious flight song of the dowitcher. It was a
sibilant, whistling song, rather loud and with a staccato effect. Doctor
Oberholser, whose ears are better than mine now are, wrote down his
impressions of it for me. Three short notes were heard separately,
_tíliloo_, _tídilee_ and _tíchilee_, accented on the first syllable; the
last two were commonest. The complete song sounded like
_tídilee-tí-tscha-tscha-tscha_ or _tíchilee-tí-tsocha-tscha-tscha_, with
numerous variations and combinations of the above notes, a very striking
song. This is somewhat similar in form to the song of the long-billed
dowitcher heard on its breeding grounds and described by Dr. E. W.
Nelson (1887); it is probably a courtship song.
_Field marks._--The dowitcher when standing is a fat, chunky bird, with
short greenish legs and a very long bill, with which it probes
perpendicularly. In flight it also appears stout and usually carries its
long bill pointed slightly downward; in adult plumage it appears very
dark colored. It has none of the slender appearance of the yellow-legs
and its flight is steadier. When seen flying away from the observer the
grayish white central band on its back is conspicuous, as are the black
and white, barred tail feathers.
