Sp Ch.— The smallest of all known species of this group found in North America. Bill about as long as the head, slightly 
curved towards the end, which is very slightly expanded ; grooves in both mandibles to near the tip ; wing long ; tertiaries nearly 
as long as the primaries; tail short; middle feathers longest; outer feathers frequently longer than the intermediate; legs long ; 
lower third of the tibia naked ; toes long, slender, margined and flattened beneath ; hind toe small. Upper parts with nearly 
every feather having a large central spot of brownish black, and widely margined with ashy and bright brownish red ; rump and 
middle of the upper tail coverts black ; outer coverts white spotted with black. Stripe over the eye, throat, and breast pale 
ashy white, with numerous small longitudinal spots of ashy brown ; abdomen and under tail coverts white. Quills dark brown 
with the shafts of the primaries white ; tertiaries edged with reddish. Middle feathers of the tail brownish black ; outer feathers 
light ashy white. Under surface of wing light brownish ashy, with a large spot of white near the shoulder ; axillary feathers 
white; bill and legs greenish brown, the latter frequently yellowish green. Total length from tip of bill to end of tail about 5| 
to 6 inches; wing, 3£ to 3| ; tail, If; bill to gape, f ; tarsus, J inch. 
Hab. — Entire temperate North America. 
This little bird is apparently quite as abundant on the western as on the eastern coast of the 
republic. Specimens from western localities seem to be slightly larger, and perhaps a shade 
more ashy in color, but we can make out no specific distinction.
