smaller colony in a large grass field near Plainsboro. By April the last 

 stragglers have left for their more northern breeding grounds. 



76 (368). Barred Owl. Syrnium nebulosum {Forst.). 



A rather uncommon resident except in the swampy timberland near 

 Monmouth Junction and at Bear Swamp, where I have frequently seen 

 individuals at dusk. I have never found the Barred Owl breeding, but 

 Mr. Scott secured a nest and three eggs April 3, 1878, and another nest 

 containing one &gg partly incubated April i, 1879. Another nest was 

 taken by Prof. Phillips. 



77 (372)- Saw-whet Owl; Acadian Owl. Nyctala 



acadica (Gniel.'). 



A rather erratic and very local winter resident. Arriving from the 

 north in December they retire to the shelter of some cedar grove where 

 they remain until early spring. I have met with this species but once 

 and quote the following from Mr. Scott in the Bulletin of the Nuttall 

 Ornithological Club, Vol. IV, No. 2, p. 85, for April, 1879. — "I have 

 never noticed this species here before ; it appears to be very common 

 this season." Mr. Scott collected during that winter about twenty-five 

 individuals, all of which are now in the University Collection. Mr. 

 C. F. Silvester of the University tells me that one was shot on Mt. 

 Rose during February 1901. >^ 



78 (373)- Screech Owl. Megascops asio {Linn.). 



A common resident breeding early in April in nearly all the 

 orchards. The grey phase of plumage seems to predominate through- 

 out this section, but during 1898 seven of the nine owls that came under 

 my observation were in the red plumage. 



79 (375)- Great Horned Owl. Bubo virginianus 



{Gmel.). 

 At present this species is rather uncommon, but not as infrequent 

 as Syrnium nebulosum. One is occasionally seen in the big woods near 

 Cedar Grove, where an adult was recently shot and is now in the Uni- 

 versity Collection. During the past winter (1901) Mr. D. Miner Rogers 

 saw one near the Millstone, and although but two nests have been found 

 during the last five years, they undoubtedly breed every spring at Cedar 

 Grove and Sorrel Mountain. Mr. C. F. Silvester took a nest early in
