HAWKS AND HAWK-LIKE BIRDS. 1ST 



CUCKOO. Plate 77. 13-14 inches. Upper parte 

 blue-gray, becoming dusky-brown on the wings and 

 blackish on the tail, the feathers of the latter spotted 

 centrally and tipped at the ends with white; neck 

 and breast paler blue-gray ; under parts white, barred 

 across with black ; bill dark, long, pointed, not hooked ; 

 feet yellow. Summer migrant 



Eggs. Very variable, but mostly of a greenish or 

 reddish -gray ground, spotted and blotched with ashy- 

 brown, chiefly at the larger end, and placed singly 

 in the nests of other birds, principally those of the 

 Meadow-Pipit, Pied Wagtail, and Hedge-Sparrow, to 

 the eggs of which, with exception of the Hedge- 

 Sparrow's, they bear at times a general resemblance. 

 Average size, '85 x '75 inch, but variable (plate 127).

 of traversing an open meadow with low, scouring 

 flight, putting up the small birds as it goes, it en-
