Order STKIGIFORMES. 



The eggs of the Owls are invariably plain white when first laid, 

 but usually, after incubation has commenced, they acquire a creamy 

 or yellowish tinge. Typically they are spheroidal in shape, but the 

 eggs of some species are regular ovals and those of others elliptical. 

 The shell is frequently glossy and sometimes highly so, and in texture 

 smooth. The larger eggs, however, frequently exhibit pores and 

 granulations.
