contained not only the outside of the nest, but also a reflection of 

 the inside. 



The reflection of light with mirrors has also been used suc- 

 cessfully in photographing Chimney Swifts' nests twenty feet 

 down in dark chimneys: Barn Swallows* nests fastened to the 

 rafters inside of buildings ; Cliflf Swallows' nests fastened beneath 

 the eaves of a bam ; Bluebirds' nests within holes in trees ; Water 

 Thrushes' nests in dark crevices in the banks of streams ; and 

 many others.

PHOTOGRAPHING BIRDS BY FLASHLIGHT. 



The photograph shown in Fig. 6 is that of a female Prairie 

 Horned Lark siting on her nest with feathers ruffled up to shield 

 the young from the chilly night air. It is a flashlight photograph 

 and was taken about nine o'clock at night. The effort to obtain 

 this night picture was made in order to learn whether the mother 

 or father brooded the young at night and if the other parent re- 

 mained near the nest. The result proved that the mother bird 

 takes care of the children and that the father bird spends his 

 evenings out. This pair of birds were accustomed to seeing a 

 camera near their nest and so settled down for the night as usual. 

 A flashlamp was placed near the nest beside the camera and ar- 

 ranged so that a flash could be obtained by pulling a string.
