General notes on North American cuckoos, followed by an 

 account of the examination of one hundred and fifty-five stom- 

 achs of botli species. Food was found to consist almost exclu- 

 sively of animal matter. Nearly fifty per cent, of the whole was 

 composed of caterpillars, of wiiich, contrary to the usual habits 

 of birds, hairy species were in the majority. The percentage of 

 Orthoptera ranged from tlnee per cent, in May to forty-three in 

 July, mostly urboreal forms, and there were from five to six 

 and one-half per cent, of miscellaneous insects, beetles and bugs 

 respectively. No particular support was found to the accusation 

 that they are in the habit of sucking eggs of other birds.
