SOME SUGGESTIONS FOB BIRD STUDY. 



fork of the tail is not so marked as in the Swallow. 

 The nest is placed in the upper corner of a window or 

 similar sheltered situation, and is composed of mud, grass, 

 and feathers. Unlike the Swallow's, it is built close up, 

 with only a small hole left for entrance and exit. The 

 eggs, 4 to 5, are pure white, about f inch long.

 also type of bill. 



The feeding habits of the Martin are similar to those of 

 the Swallow, and the remarks made with reference to their

 distribution is more local. It is greyish brown above, 

 brownish white below. Eggs rather smaller, also white.
