104 THE AMERICAN MIDLAND NATURALISt 



spotted sandpiper, and American goldfinch. Although the number 

 of species seen vvas so large, it included very few of the rarer birds 

 of this vicinity, that possibly of most interest being the blue-winged 

 warbler. In view of the backwardness of the season, there were 

 surprisingly few very late records made on this day. Two ducks, the 

 golden-eye and pintail, however, were present later than in any 

 previous or subsequent year, while the junco had remained also 

 much beyond its ordinary date of departure. 



In the following annotated list in order to show the differences 

 in the conspicuousness of the various birds, the number of each 

 species seen is given separately from those that were only heard. 

 This is of further interest as showing how large a part the notes of 

 birds play in their identification in the field.
