coverts grayish-brown, with paler edges, and no trace of olivaceous. Bill

8.35; wing from carpal joint, 2.85. Prepared specimen: Total length, 4.80; 
wing, 2.75; tail, 2.25; difference of 3d and 10th quills, .73; exposed portion 
of lst primary, .58, of 2d, 1.88, of longest (measured from exposed base of

gape, .63; depth of bill, .15 ; tarsus, .65 ; middle toe and claw, .51, claw alone, 
17; hind toe and claw, .41, claw alone, .19.

not differ appreciably from the male, but is a little smaller. Young 
and autumnal specimens are perhaps a little more brightly colored.
