IS- THE AMERICAN MIDLAND NATURALIST 



Bay-breasted Warbler 



Dendroica castanca 

 A large warbler, and conspicuously reddish, the Bay-breasted 

 is also quite abundant. The number of adults is often small, and 

 most of the specimens that appear, even in spring, are immature 

 birds. In May or June, 191 7, this species was not heard to sing. 



Blackburnian Warbler 

 Dendroica fusca 

 All bird lovers are desirious of seeing this warbler, and once 

 they have had the pleasure, they are anxious to have it repeated; 

 for the beauty of the Blackburnian Warbler is justly famous. 

 Usually in high situations, this active little bird seems almost a 

 part of the sunshine that brightens the tree-tops. His song is 

 quite distinctive, but I did not hear it in the spring of 19 17. 



Black-poll Warbler 

 Dendroica striata 

 One of the latest warblers to arrive in spring, the Black-poll 

 is also usually the last to leave for the north. This year it was the 

 most abundant warbler in the woods after May, and its tick, tick 

 note is always heard when the bird is here. The female Black-poll 

 is so plainly marked that beginners are often unable to identify it. 



vSycamore Warbler 

 Dendroica albilora 

 One of our rarest warblers is the Sycamore. It appears ir- 

 regularly, and may not be seen for many years. This year, 191 7, I 

 was fortunate enough to find one on the last day of its stay here, 

 near the St. Joseph River. It was in song, and showed a preference 

 for pine trees. Two other observers told me that this warbler had 

 been seen for three weeks previous to the date on which I found 

 it — June 21. Only one bird was ever seen, and the) - could not 

 be certain whether the species was breeding here or not. 



Black-throated Green Warbler 

 Dendroica virens 

 This is one of our commonest warblers. Sometimes it arrives 

 late in April, and may prolong its stay until early June. Its plumage 

 is striking, and much admired by young observers. The note of 

 this species, which is frequently heard and easily remembered, 

 grates upon the ear of the listener.
