The eggs of the Brazilian Caracara are normally of a short 

 oval form, but some are pyriform and others spheroidal. The shell 

 is smooth but without gloss. The ground-colour varies from 

 cream to pale buff and reddish buff, and this is marked with spots, 

 smears, and blotches of different shades of reddish brown. The 

 markings sometimes cover only one-third of the ground, and some- 

 times nearly conceal the whole of it. The eggs measure from 2-05 

 to 2*5 in length, and from 1-7 to 1-95 in breadth.
