25th, when it is often seen in the gardens and orchards, 

 gleaning insects among the opening foliage. 



66. Dendroica canadensis Baird. Black-throated Blue 

 Warbler. Common from May 15th to 25th, and again the 

 fore part of September. Found in the breeding season on 

 Mt. Holyoke (C. W. Bennett), and along the ridges in the 

 western part of the State (B. Hosford). 



67. Dendroica coronata Gray. Golden-crowned War- 

 bler. Myrtle Bird. Yellow-rumped Warbler. Very abun- 

 dant spring and autumn visitant. Commonly arrives first 

 week in May, in great numbers, but generally passes rap- 

 idly northward, and is usually abundant but four or five 

 days. Stragglers are sometimes seen the last of April, 

 and a few as late as May 15th. Are often so abundant as 

 to seem to be in an almost continuous loose flock, equally 

 common in orchards, thickets, cultivated grounds and 

 woodlands, keeping up a constant motion northward, others 

 continually arriving to fill the places of those which have 

 passed on. In autumn they are longer in passing, moving 

 much more leisurely than in spring ; are very abundant 

 for ten days to two weeks in the fore part of October. 

 Often alights on the ground, particularly in autumn, and 

 is then rather more common about cultivated fields, flying 

 along fences and hastening from field to field, than in deep 

 woods. None breed here. 



68. Dendroica Blackburnice Baird. Blackburnian War- 

 bler. Not very uncommon. Arrives about the middle of 

 May. A few probably breed, having taken it here June 

 24th. Most common in mixed or hard wood forests. The 

 nest was found in the eastern part of the State some years 

 since, by Dr. Brewer. (Aud. Orn. Biog., vol. v., 73.) 



69. Dendroica castanea Baird. Bay-breasted Warbler. 

 Very rare. Have taken it May 20th and May 25th. One 

 taken in July, 1862, by B. Hosford. 



70. Dendroica pinus Baird. Pine Warbler. Very com- 

 mon, breeding plentifully. This is the earliest warbler to 

 arrive in spring, except perhaps D. palmar um, and remains 

 till the second week of October. In 1861, they were com- 

 mon in the pine woods April 4th, though the ground was 

 covered with several inches of snow, some of which re- 

 mained for a week after their arrival. During the last
