THE GREY HERONS. GENUS ARDEA. 



Ardea, Linn. Syst. Nat. i. p. 283 (1766). 



Type, A. chierea^ Linn. 



In the genus Ardea the tail-feathers are twelve in number, 

 but the middle toe is not so long as in Phoyx, the tarsus being 

 longer than the middle toe and claw combined. The claw on 

 the hallux, or hind-toe, is curved and is not half so long as the 

 hallux itself. The edges of the mandibles are distinctly serrated 

 and there is a faint trace of a notch just before the tip of the 

 upper mandible. This notch, however, is often obsolete.
