four thousand feet alwve the sea. In one instance a pair was found by Dr. Ludwig 

 Iloltz occupying the deserted nest of a Hooded Crow, built ou a bush near the sliore, 

 ten feet from the ground. Tlie same pair was said to have nested there during sev- 

 eral successive years, in another instance Mr. CuUett observed a pair near Troud- 

 hjem, in the summer of 18G8, which had taken possession of the nest of an old Crow, 

 on the top of a tir-tree. The eggs when removed were replaced by another set. 



Dr. Key informed Mr. Dresser that a careful measurement of fifty specimens gave 

 as the average size of the egg of tliis bird, 2.o0 by 1.G3 inches, the largest measuring 

 2.55 by 1.62, and the smallest 2.11 by l.GO.
