THE GREY HERONS. GENUS ARDEA. 



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



Type, A. cine?-ea^ Linn. 



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

 but the middle toe is not so long as in F/ioyx, 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.
