The Wheatear. 



It is generally well concealed. The eggs are from four to seven in number, 

 greenish blue or greenish white, with sometimes a few purplish-brown spots 

 round the larger end. 



This is a large Chat of very pale and sombre colour, which 

 IHE ISABELLINE might be mistaken for a female or young of the Common 

 Wheatear, but may always be distinguished by its longer leg, 

 the tarsus measuring i-2 inch instead of 1-05 as in the 

 common species. The sexes are alike in colour, being of an earthy-brown, more 

 or less ashy, and the under surface is light isabelline-rufous, becoming sandy-white 

 on the throat and abdomen ; the axillaries and under wing-coverts are creamy-white.
