37. P. tigrina £d. Capk May Wahbler. Very common mi- 

 grant. May 7th to 25th, and September 5th to 20th. In spring, found 

 almost exclusively in the tops of the trees; in autumn found in large 

 numbers along roadsides, borders of woods and fields in company 

 with Dendroeca palmarum, from which it is, with difficulty, distin- 

 guished at gunshot, so closely alike are their habits and movements 

 at this season.
