INTRODUCTION. 



A special interest in the little Golden-winged Warbler has 

 remained with me ever since May 2.2, 1891, when I found 

 them nesting for the first time. For a few years previous 

 I had known the bird only as a migrant, as I supposed, and 

 passed them by even to the middle of May, at which time 

 in later years I found them to be regular, — not to say abund- 

 ant, — breeders. 



Observing that no great amount has been written on the 

 life history of this species, I have undertaken the compilation 

 of this paper, as a contribution to existing knowledge, using 

 data and records personally collected during days spent in 

 their haunts. 



During the past few years, efforts were made to secure a 

 photo of the old bird on or near the nest, but after hours of 

 waiting with the anxious birds only a short distance away, I 

 was each time compelled to fold my camera and give up the 

 attempt. The mother bird is rather tame and allows a close 

 approach to the nest, not leaving until the hand is thrust down 

 almost upon her; but when once disturbed she will not return 

 until the intruder is well out of sight. At the last nest I 

 found in 1903, two attempts were made to get a photo of the 

 sitting bird but each time, just as I got the camera placed, the 

 mother became suspicious and slipped away, and although I 

 went quite a distance away and hid in a clump of briers, she 

 would not approach the nest while the camera remained near. 



In June, 1901, I got a picture of a young bird which had 

 just fluttered from the nest, and a half-tone of this is shown 

 with the plates. 



The Color Chart was prepared after a careful study of the 

 eggs and their coloration. 



The plates were made from photos by the author, and are 

 accompanied by proper explanations.
