Swallow, Tree (continued!) 



Call no. 



Nu SuT4 Large Young Bird on Perch. (1912) Bailey 



Nu SuT5 Adult and Five Young Birds on Limbs of Dead Tree. 

 West marsh, near Ithaca. (June 21, 1908) Allen 



These young birds have been removed from the nesting hole. 

 The young at this age are fed like ordinary birds : namely, the 

 old bird alights and places food far down the throat of the young. 



Nu SuT54 Adult on Wing Feeding a Young Bird. Renwick, near 

 Ithaca. (June 19, 1911) Allen 



After the young birds leave the nest the old bird never alights 

 to feed them, but swings past and drops the food into the open 

 mouth. j 



Nu SuT6 Adult Flying to Its Nest in a Hole in a Dead Stub of 

 Tree. Near Ithaca. (June 26, 191S) Allen 



The bird is checking its flight, turning before alighting. 

 Observe the position of the tail. 



Nu SuT8 A Multitude of Swallows, Largely Tree, on Telegraph 

 Wires. Montezuma marshes. (July 31, 191S) 



Preparatory to their southern migration swallows gather in 

 large flocks and for weeks at a time they frequent certain points 

 while their numbers continue to increase by fresh arrivals. Note 

 the date of the picture. 



Swift, Chimney (Chcetura pelagica) 



While ordinarily called a swallow, the swift is more nearly 

 related to the nighthawks. In former times this bird nested in 

 hollow trees. Now, with the advent of man, it uses the chimneys 

 and barns for nesting sites. It is never on such perches as fence 

 posts or telegraph wires. If it alights, it does so on some vertical 

 surface. It may be noticed in flight early in the morning or late 

 in the afternoon. 4.8-5.6 



Nu SwC2 Nest with Five Eggs. (July 1906) Bailey 



Notice the materials that compose the nest. The twigs are 

 broken off by the bird while flying ; they are cemented together 

 by a gelatinous substance secreted by the salivary glands of the 

 bird. The nest is not lined.
