16. Vermivora pinus. BLuE-wincep WarBLER.— This rare Wis- 
consin warbler probably breeds in the Baraboo Bluffs and possibly also 
in the river bottoms, in suitable localities; at least the following records 
would seem to indicate that such is the case, though no nests were located. 
A pair collected June 22, 1913, and a female in the same locality June 24, 
and one male each, June 9 and 11, in the Dane County river bottoms. 
17. Vermivora chrysoptera. GoLDEN-wINGED WaRBLER.— Two 
broods of young of this species, just able to fly, were observed in the Bara- 
boo Bluffs, July 1, 1913. Have also the following records of specimens 
collected in Sauk County: adult male, June 12, adult female June 22, and a 
pair, July 1, 1913. 
18. Dendroica cerulea. CrRULEAN WarBLER.— Near the source 
of Otter Creek in the Baraboo Bluffs, there are large tracts of tall timber, 
principally of hard maple, basswood and oak, growing on the level, and 
rather swampy ground, between the hills. In this region, the Cerulean 
Warbler is a common summer resident, and undoubtedly breeds, though 
I did not succeed in locating any nests. A number of specimens were col- 
lected, (May 30 to July 3, 1913) nearly all of which were the easily located 
males, only one female being secured. 
19. Dendroica fusca. BLackBURNIAN WARBLER.— As a migrant, 
this species is fairly common at times in the Baraboo Bluffs, but I have 
only two summer records. One adult male being secured June 27, and 
another July 1, 1913. 
20. Oporornis formosa. Kentucky WaRBLER.— Two specimens of 
this rare species (for Wisconsin) were seen June 9, 1913, and one adult 
male was collected. As the actions of the birds strongly indicated that 
there was a nest in the vicinity, a very careful search was made, but with- 
out result. Kumlein and Hollister (Birds of Wisconsin, 1903, p. 117) give 
seven records of this species, six of which were for Lake Koshkonong, in 
spring. 
21. Icteria virens virens. YELLOW-BREASTED CHat.— Have only one 
record for this species, an adult male, collected in Dane County, June 13, 
1913. A few were also heard.
