There is much yet to be studied in the habits of these birds, 

 and much that requires the attention of a specialist. Even the 

 ornithologist who devotes his time to his proper pursuit is too 

 much occupied in May and June to make the necessary obsei'- 

 vations. Few monographs in Natural History could be more 

 interesting than one of the Cow-birds.

 marshes, either on the ground, when it is generally placed upon 

 a tussock, or in a bush, the alder being frequently chosen for 

 this purpose. Says Mr. Maynard : " I have found the nests 

 on an island in the marshes of Essex River, placed on trees 

 twenty feet from the ground ! In one case, where the nest was 

 placed on a slender Sapling fourteen feet high, that swayed 

 with the slightest breeze, the nest was constructed after the 

 manner of our Baltimore Orioles, prettily woven of the bleached 

 sea-weed called eel-grass. So well constructed was this nest, 

 and so much at variance with the usual style, that had it not 

 been for the female sitting on it, I should have taken it for a 

 nest of I. Baltimore. It was six inches deep." The nest of 

 the Red-winged Blackbird is generally constructed of dry grass- 

 es or partly hairs ( — occasionally also of roots), which are 

 firmly attached to any neighboring branches or stalks, or which 

 form a very neat hollow in the grass. In Eastern Massachu- 

 setts it is finished soon after the middle of May. The eggs of 

 each set are four or five, average I'OO X "75 of an inch, and
