COMMENTS 
It is quite likely that collectors have not distinguished 
correctly between certain species. For example Knight 
gives 256 (Solitary Sandpiper) as fairly common, while all 
recent collectors refer it to 256a (Western Solitary Sand- 
piper). It may be that 627 (Warbling Vireo) and 627a 
(Western Warbling Vireo) have likewise been confused. 
The latter is probably the Wyoming species, 1f this sup- 
position is correct, and 256a is the Sandpiper. We had a 
large number of skins of Wilson's and Pileolated War- 
blers, or at least some were labeled the one and some the 
other. They were indistinguishable except that there was 
a slight variation in color. 
It is quite possible that some collectors have confused 
two species of Red Wing Blackbirds and that only one 1s 
-represented in Wyoming. The probability is that both 498 
(The Red-winged Blackbird) and 498d (The Thick-billed 
Redwing) are to be found in the state. 
The Long-crested and Black-headed Jays are quite sim- 
ilar, but there seems good evidence that both species occur 
in southern Wyoming. It is possible that they are all varia- 
tions of a single species. 
Knight gives 204, 212, 478b and 585c in his hypothetical 
list. 
NEW - RECORDS FOR THE STATE: 
Since the publication of W. C. Knight's “Birds of Wyo- 
ming,’ in 1G02, the following forty-five birds, not recorded 
by him, have been found by one or more of the collectors 
who have worked in Wyoming. The records for these
