The White-throated Warbler at 3\v.m u pgan,

Twelve years ago I indulged in great satis- ''^'■'3 V-'oj: "'-^N 

 faction over the capture of my first specimen P-iiqi aq; si siqx 

 of Belminthophaga leucobronchialis, at that t -suoipB 351 Xpn^n 

 time regarded as an exceedingly rare species, psiquissa-i 1; suoipi: 

 but during the last few years other collectors '"'='.1° Suiaq '.ispBo.iq 

 have obtained and taken so many specimens '^1"! a-'oui b si tpied 

 that its capture is now scarcely considered de- ' lunasnjAj ui33ij3uiv 

 serving of note, yet the securing of another Juajiaaxa ui si 'sikui 

 specimen, and hearing its song many times re- '^A\ s,3ou3.ia\i!i i: aq 

 peated, drew my attention to the fact that I '1* '-'aiq-n^M « loqs j 

 had not read anything relating to its notes.' ^dan;A\s 'saoi }o 



This was early in the season (May 8th, 1889). '^"ipads pjiqx y 

 I was taking a walk into the woods for the :ymour took a male 

 purpose of observing and noting the new ar- s reported by him in 

 rivals, when my ear caught the notes of a 3ne at New Haven 

 llelminthophaga pinus. Of course I should Sage took a male 



have recorded it had not the bird at that same 



moment perched on a twig close at hand and in lO 9 



full view. Although I observed that the note ' < 



liad less of the whispered lisp of pinus, and 



more of the vocal of chrysoptera, yet the vari- ] 



ation was of such a character that in itself it t 



would scarcely have attracted my attention, 



but once noticing I readily perceived the dis- , 



tinction, and saw that it was a perfect imita- 1 



tion of the first part of the song of chrymptera 



without the concluding chatter that invariably 



terminates that of the latter species. 



My bird was (unlike my former experience) ', 



very shy, after having inspected me once to 



his satisfaction close at hand, and too near to 



be made a specimen of, and for three hours I 



followed the elusive notes back and forth 



through the forest with all the caution and 



strategy of which I was master before success 



rewarded my labors. This specimen exactly 



resembled my former capture, and it seems to 



me the distinction is altogether too marked 



and permanent to render tenable tlie recently 



advocated theory accepted by some of hybrid- 1 



ization. But I have found in ornithological I 



matters it is so easy to be mistaken tliat I only | 

 ventui-e to express my doubts by a very small \ 

 interrogation point.
