The eggs of the Western Brown Falcon are short ovals or 

 ellipses in shape, slightly rough and without gloss. They are quite 

 of the Falcon type, some eggs resembling those of the Jer-Faleons, 

 others those of F. jur/ger, while others again are as richly coloured 

 as some of the eggs of the Peregrine Falcon. They measure from 

 1-95 to 2-27 in length, and from 1-44 to 1-58 in breadth.
