BIRDS. 



BY \V. E. D. SCOTT. 



Second Paper Icterus cucullatus. 



The individual taste of birds in the matter of their nests is so 

 well exemplified by the great differentiation in the nests of the 

 Hooded Oriole {Icterus cucullatus), which is a very common 

 breeding bird in the canon described in the former paper of this 

 series, that I propose to give a detailed description of ten nests 

 t:iken here during the past summer, and incidentally to call at- 

 tention to other nests of the same species taken in regions close 

 at hand. 



The birds arrive here about the middle of April, and are to be 

 found until the last of .September, and a few even well into
