The Black-headed Siskin is extremely plentiful in the Ajo 

 district, and usually frequents the Tala and other woods, where 

 its delightful little song can be heard throughout the year. 



The nest is an extremely neat little cup-shaped structure 

 composed of wool and thistle-down and lined with hair, and 

 four eggs appear to be the complete clutch, though three are 

 often found. It is placed in a bush or in the fork of a tree, 

 and is not always easy to detect. 



The eggs vary somewhat in shape and colour : some are of 

 a very delicate semitransparent blue, others are more opaque, 

 and some are more or less spotted on the obtuse end.
