Notes on the Food and Temperatures of 

 Cormorants.

Thanks to the hospitality of Messrs. A. G. and E. Rymill,

 March 25th, a return was made to Port Adelaide. 



Two species only of cormorants were seen — the orange

 places, though a few of the orange-faced birds are usually

 orange faced birds were secured, and their temperatures 

 taken as soon as they could be collected, none being taken 

 more than ten minutes after death, and some wounded birds 

 while still alive. The temperatures were as follows: —
