'S83-] Grundtvig 071 Warblers of Wisconsin. 6q 



Helininthophila peregrina ( W//s.) Cad. May 19 a single 

 male was taken by S. W. Willard in a thicket east of Wolf 

 River. The 3ist both sexes were very numerous, ranking in 

 numbers with D. sU-iata. After this the number diminished 

 somewhat, but the species was still quite common until the 

 27th, when it suddenly disappeared. 



Dendroeca aestiva {^Gm.) Bd. A single male was taken 

 May 3. The 4th it was noticed intermingled with many flocks, 

 and on the 5th it outnumbered all its associates. May 14 they 

 were everywhere unusually abundant, exceeded in numbers only 

 by S. ruticilla and D. pennsylvanica. They breed here abund- 

 antly. The first o.^^ was found June 2. May 12 I shot a male 

 that had the crown curiously striped with several rich orange- 

 brown marks. 



Dendrceca virens {Gm.) Bd. Several males were noticed 

 May 4. After that date and until the 22nd it was occasionally 

 seen in the other flocks. May 8 being the only day it was quite 

 common. The 7th, 9th, and from the 13th to the iSth, none 

 were noticed. 



Dendroeca ceerulescens (Z.) Bd. May 8 a few males were 

 seen ; the numbers then gradually increased until the nth, when 

 the first females were noticed. May 12 none were observed, but 

 after that date it was occasionally seen until the 23rd. May 31 a 

 single male was noticed. 



Dendrceca coronata (Z.) Gr. The first specimen was 

 taken April 5 ;. single ones were also taken the loth, 12th, 14th 

 and iSth. April 2r the first flock arrived. From this date the 

 number increased rapidly. April 30 other Warblers were found 

 intermingled throughout the flocks, and by May 8 the number 

 was quite insignificant ; from the 9th to the 30th only a few sin- 

 gle ones were observed. Undoubtedly this species was the most 

 abundant of all the Warblers. 



Dendrceca blackburnise (Gm.) Bd. The arrival of this 

 Warbler was indeed very singular. The first one, a male, was 

 noticed May 3. The 4th, 5th, and 6th a few were seen, but the 

 7th none were to be found ; the 8th, however, enough of them 

 had arrived to far outnumber the other Warblers then present, 

 but the very next day not one was seen. Excepting the i6th 

 and 17th, it was noticed each day from the 9th until the 23rd, 

 when it disappeared.
