A Series 
of Eggs 
cooperi. 
of Accipiter 
by j. p. N. 
The eggs of Cooper’s Hawk ( Accipiter coop-, 
eri ), are usually referred to as being unmarked, 
and so the majority of sets are, but well defined 
spots are not uncommon, and two sets with 
bold and heavy markings will be referred to 
below. 
The writer is indebted to the well-known col- 
lector and naturalist, “ J. M. W.” (Mr. C. L.j 
Rawson), for all the finest sets in the following- 
series, and the acknowledgement is cheerfully 
made. Without his help the series would have 
been far less complete. 
Set I. May 5, 1886. Black Hawk County, 
Iowa. Collected by G. P. Four eggs, fresh. 
Bluish-white. Three of them are entirely un- 
marked, but the fourth has a few specks of

1.81x1.41.
