Black THROATED Blue Warbler, Dendroica caerulescens. 

 Where the preceding- one is found, this one may also be looked 

 for. They frequent bushy, open woods and are mostly seen in the 

 branches of medium sized trees. Its best song is : Dill-dill dill- 

 dree, rapid, ascending. When busy feeding or later in summer 

 it abbreviates this into, Re-deree-di, Tsree tsree Isrce, or even a 

 shrill, whistle-like, Trree. 



Magnolia Warbler, Dendroica mamlosa. This handsome 

 black and yellow warbler has quite a repertoire of lays and ditties, 

 which all however do not amount to much. Its best performance 

 is a loud, impulsive, Iree deree di. At other times it sings like 

 the Chestnut-sided warbler: Peary, peary pee a ; then again monoto- 

 nously: 2''see, tsee, tsee, etc., or it utters a rather melodious 

 disyllable Tsee-wii, tsee-ivit. 



Blackburnian Warbler, Dendroica blackburnice. This winged 

 gem of black, white and deep orange sings little and then very 

 poorly, a faint, hesitating. Dee dee dee, in one pitch of tone, or 

 even only : De de de. 



Pine Warbler, Dendroica vigorsii. True to its name, this 

 warbler lives only in pine-woods or in single pines amongst de- 

 ciduous trees. Its color is dull olive and the song exactly like 

 that of the Chipping Sparrow ; it cannot well be reproduced by 

 syllables. 



Canadian Warbler, Wilsonia canadensis. This warbler is of 

 a somewhat pensive and retiring disposition. It prefers swampy 

 and bushy places. The breast is bright yellow, with a neck-lace 

 of black spots, back bluish gray. The only song I have heard 

 sounds like a faint imitation of the Maryland Yellow throat, a 

 subdued, halting : Witchety, rmtchety. When alarmed in their 

 quiet haunts they utter a sharp tsip or tsink. 



Blackpoll Warbler, Dendroica striata. Black and white, 

 with a black crown, larger than most warblers, Its song is a 

 very insignificant dry : De de de, uttered very leisurely. 



Nashville Warbler. Helnnnthophila ruficapilla. A bright 

 yellow warbler, bluish gray on top. The song is variable. Some 

 give it: Wee-see, wee-see, wit-a-wit-wit ; others: Ke-tse, ke-tse, 

 ke-tse, chip-ee-chipee-chtp. Rather loud and lively.
