14 Wood, The Spring Migration, 1907, at Ann Arbor, Mich. \^^^ 



Tennessee Warblers suffered nearly as great a loss, as did also the 

 Nashville Warblers. A few Chestnut-sided, Bay-breasted, and 

 Black-poll Warblers, were found dead. [The small number 

 found of the last three may be accounted for by these species being 

 late arrivals, thus encountering better conditions.] Four Palm 

 Warblers, 2 Baltimore Orioles, 1 Rough-winged Swallow, 2 Purple 

 Martins (the most of the last species did not arrive until warmer 

 weather), 1 Rose-breasted Grosbeak, 1 Red-eyed Vireo, 6 Oven- 

 birds, a few Prothonotary Warblers and several Yellow-breasted 

 Chats were also brought in dead. The Myrtle Warbler was very 

 abundant, but only a few were found dead, [possibly owing to their 

 great diversity of diet, being able to eat seeds and food not available 

 to most warblers]. The Yellow Warbler also seemed hardy, as 

 none were found dead. The mortality must have been large, as 

 no effort was made to collect these dead birds, and nearly all were 

 picked up by school children. All birds observed were very ema- 

 ciated and the stomachs and intestines were empty."
