Tyrannula. thcebe, Lath. 



I shot two individuals of this species May 10th, IS-IS. Probably not very 

 rare, but impossible to distinguish it from the T. fusca without carefully com- 

 paring the two. 



TvRANNrLA A^ATICA, Gmel. 



The most numerous of the fly-catchers in Wisconsin. 



Tyrannula ptsilla, Sreainx. 



This species, so closely allied to the preceding, is not unfrequently met with 

 about the 10th of May, on its passage north. 



Tyrannus CoofKR.ir, Nutt. 



I have occasionally met with this bird during the latter part of May. 



*SF.TOrHA(iA RT.TICILLA, LillU. 



Numerous. Arrive 5th of May ; commence constructing tlieir nests 1st of 

 June. 



*Setophaga mitrata, Bona-p, 



Not numerous near Racine, which maybe considered the northern limit of this 

 bird's summer migration. 



*SKTOPHAr;A CANADKN>1S, LiuV, 



This interesting species is not uncommon with us. 



Sktophaga Wilsomi, Bonap. 



Common from the lOth to the 25th of May. 



Setophaga iviikl'ta, Wilson. 



Rarely met with. The only specimens I have were shot 1st of June, 1S50.

*VlRE0 FLAVIFRONS, Vt'eill. 



Not uncommon. First appearance from 10th to i5th of May. 



*VlREO SOLITARIUS, Vicill. 



This is by no means a rare bird in Wisconsin ; it frequents the most secluded 

 thickets. Arrives about 15th of May. 



*VlREO NOVEBORACENSIS, Gmd. 



I have noticed but few specimens of this species. Not common. 

 *VlRE3 GiLvrs, VieiU. 



This cheerful songster is rather scarce with us, perhaps the least numerous of 

 the Vireos, 



*VlUEO OLIVACKUS, Ll/liU 



By tar the most abundant of the birds of this genus; its sprightly and melo- 

 dious song is heard almost constantly during the summer. 



*PeTERIA VIRIDIS, GmeL 



A few only are to be found in the tangled thickets during the summer months. 



MERULTD.E, (10 species.) 

 MiMUS polyglottus, Laih. 



Occctsionally a straggler of this charming songster finds its way as far north 

 as Wisconsin. I saw one between Racine and Kenosha July ICth, 1651, and a se- 

 cond near the State line on Rock river, July 26th, 181G. 



*Ml.ML"S RIIFUS, Linn, 



V'ery abundant.
