522 AQU1LA 



lined with twigs, grass, wool, or other soft material, or with 

 green leaves, and in April or May 2 eggs are deposited, w r hich 

 are dull white somewhat sparingly clouded with pale purplish 

 red, and blotched with pale rufous, and average in size 2'95 

 by 2'28. 



I still believe that Gmelin's Falco mogilnik is referable to 

 this species, but as ornithologists hold such different views on 

 this subject I have deemed it advisable to use Savigny's name 

 heliaca about which there can be no doubt.

In habits and nidification it does not differ from A. heliaca
