The Marsh Hawk is one of our most common 

 summer hawks. It arrives here from the south 

 about the first of May. Color, bluish-cinereous 

 above ; beneath, reddish-white. Nests, on the 

 ground ; eggs, four or five, of a dirty white color. 

 Feeds upon field mice, principally, and the num- 

 ber of these destructive little animals which it 

 devours during the breeding season is almost 

 incredible. It is consequently entitled to the 

 protection of the farmer.
