BIRDS OF NEW YORK STATE 99 



Swallow, Bank (continued) 



Call no. 

 Nu SuB4 Several Nest Entrances in Sandbank, Near View 



A pair of birds has a nest at the end of each burrow. 



Nu SuB6 Five Adults Hovering before Nests Allen 



Note the various positions of the wings. Are the wings used 

 for anything but propulsion? Their shape is characteristic of 

 swallows. 



Swallow, Barn (Hirundo erythrogastra) 



The most generally distributed swallow of New York. This 

 species is very beneficial, being insectivorous, but not uncom- 

 monly the farmer unwisely knocks down the nest built in his 

 barn and sheds. 6-7 



Nu SuC Adult Resting on Perch. (September 1914) Bailey 



This perch was used as a resting place between flights over 

 the pond near by. A distinguishing feature of the barn swallow 

 is the forked tail, the outer feathers showing like knitting needles. 



Nu SuC2 Nest of Mud and Straw Attached to Beam Supporting 

 Ceiling in Old Barn. Near Pembina, N. D. (June) 



Peahddy 



Nu SuC4 Adult with Wings Fluttering, before Nest with Young. 

 (June 1915) Allen 



This photograph was made by flashing light from a mirror 

 through a crack in the barn. Observe the size of the mouth. 



Swallow, Cliff {Petrochelidon lunifrons lunifrons) 



Found in sparsely settled portions of the State, especially the 

 Adirondacks and Catskills. It is not only a very interesting bird 

 but also a very useful one. It seems to be disappearing from 

 New York, however, partly from the disposition of farmers to 

 encourage the destruction of its nests. 5-5.5 



Nu SuE2 Many Nests along Side of Cliff. Idaho Hamilton 



This is the natural nesting site of this bird.
