Eggs of the White- crowned Sparrow are of a broad oval shape 

 and moderately glossy. They are pale greenish- white, mottled with 

 brick-red and some underlying grey spots. The density of the 

 markings varies considerably, some eggs having the ground-colour 

 almost entirely concealed, whereas in others it is plainly visible,
