WARM-WEATHER BIRDS. 21 
The woodduck is the first of our fall migrants, pre- 
ceding the cinnamon and bluewinged teals. The young 
are highly esteemed for food; the black and white 
striped side feathers, are largely used in the manufac- 
ture of artificial flies. Length 19; wing 9.50; tarsus 
{.40; extent 28.50; middle toe, 1.65. 
SUBGENUS Querguedula. 
Anas discors—BLUEWINGED TEAL — Habitat.—North 
America at large, Alaska; south to the equator, but 
not extending as far down as the cinnamon teal; also 
ranging eastward from the Mississippi, while the 
latter bird ranges westward. 
The first issue of this our tenderest duck arrives in 
latitude 37° from March 25th to April Ist, staying 
about six or eight days. The second follows a few 
days after the first has departed northward, up to and 
past the boundary line. A short period elapses when 
they likewise travel north to the southern part of Min- 
nesota and its parallel. The third soon follows, and 
stays an indefinite period, working up through TIIli- 
nois, Indiana, Wisconsin and eastward about the last 
week in April if the weather permits, the Ohio, Mis- 
souri and Mississippi, with their tributaries, furnishing 
the fly-ways. 
About the early part of August the local ducks of 
each state begin to work northward; during Septem- 
ber they flock together and form the first flight, pass- 
ing over the same grounds. The collecting or flocking 
together of the local birds, which form the first fall 
issue, presents an interesting sight. For nearly two 
days the ducks will be noticed as getting very uneasy,
