LIST OF BIRDS IN THE PARK 121 



it stays high up in the tree tops and thus escapes notice. It 

 arrives earlier than most of the Warblers, and may be looked 

 for during the first half of April. Mr. Hoffmann gives me 

 records for May 15 and for May 13, 1916. 



Black-throated Green Warbler, Dendroica virens 

 (Gmelin) tr. This Warbler is also an uncommon migrant. 

 I have seen it but once in Swope Park. 



Palm Warbler, Dendroica palmarum Gmelin tr. This 

 Warbler is quite uncommon in this part of the country. Mr. 

 Cunningham furnishes me with a record for Swope Park May 

 15, 1920. 



Oven-bird, Seiurus aurocapillus (Linn) sr. Swope Park 

 is one of the few localities in this part of the country in which 

 the Oven-bird nests. It is to be hoped that parts of the Park 

 frequented by this and other retiring species will be left un- 

 disturbed so that we may continue to have the pleasure of its 

 presence. It nests in Hazel Dell. Quite a few migrants may 

 be found in various parts of the Park during the first week 

 of May. 



Grinnell's Water-Thrush, Seiurus noveboracensis notabilis 

 Ridgeway tr.... This Water-Thrush is much less common than 

 the next. I have seen and heard it in the Park but few times. 



Louisiana Water-Thrush, Seiurus motacilla (Vieillot) sr. 

 The Louisiana Water -Thrush nests in the Park in Hazel Dell 

 and in the lower portion of Shiloh Hollow. It is found in 

 company with the Grinnell's Water-Thrush in the early half of 

 May. The two may be distinguished most readily by their 

 song. 



Kentucky Warbler, Oporornis formosus (Wilson) sr.
