BIRDS OF PENNSYLVANIA. 
Genus SYMPHEMIA Rafinesque. 
Symphemia semipalmata (Gmel.). 
Willet. 
Description. 
Size large, bill long, thick and grooved to middle ; legs stout and long ; lower half 
of tibise bare ; toes short and stout with marginal membranes and basal webs con- 
necting inner and outer with the middle toes ; tail feathers nearly even. This spe- 
cies varies more or less with age and season. Three specimens, male and females, 
(taken in August), before me have bluish black legs, blackish bills, the latter 2^ and 
2| inches long. Upper parts brownish-gray, darkest on head and back, streaked 
with dusky, and many of the feathers with whitish edges ; back of neck ashy-gray ; 
foreneck, the sides and portion of breast grayish, with dusky streaks or spots ; chin 
upper part of throat, breast, except on sides, belly and crissum white ; axillars, 
lining of wings, primary coverts and ends of primaries black ; most of the upper 
tail-coverts, most of the secondaries and a large space on primaries, white ; tail ashy- 
white with fine dusky markings. Length about 16 inches ; extent about 28. 
Habitat . — Temperate North America, south to the West Indies and Brazil. 
Rare and irregular spring and fall migrant in eastern Pennsylvania, 
and when observed here is, usually, seen late in August. Mr. Sennett, 
and the Messrs. Thompson, of Erie city, have never known the Willet 
to visit that locality ; and none of the naturalists and collectors, whose 
reports are before me, have observed this species in any of the central, 
northern or western counties of the state. I have two specimens, one 
taken in Delaware county (August, 1885), the other was killed by flying 
against a telegraph wire along the Brandywine, in Chester county 
(August, 1887). Dr. Detwiller, of Bethlehem, has secured specimens 
(mostly “after severe fall equinoctial storms” about the Delaware and 
Lehigh rivers. Mr. W. H. BuUer, Lancaster county, says : “ The Wil- 
let has, occasionally, been killed on the gravel bars along the Susque- 
hanna river ; the last one, to my knowledge, was captured in the autumn 
of 1878.” 
The Willet subsists, mainly, according to difierent writers, on worms, 
various aquatic insects, small crabs, minute shell flsh, small shells, etc.
