HABITS. 

 The song of the Indigo Bird in Massac! lu setts, is a lisping warble, ending so abruptly 

 as to appear half finished, but in Penns3'lvania, this lay is so much clearer and longer, 

 that I did not, at first recognize the author. These birds are fond of" thorny thickets 

 that border on fields grown up to bushes, and the males may l)e seen ]3ei'C.hed on the top- 

 most limb of some tree, giving tlie peculiar song. The nests are placed low, often onl}' a 

 few inclies from the uround, and tlie euiii'S are detiosited earlx in .Tune.
