call-note, which our best field-naturalists render as " tchick 

 or "chink." It is certainly a peculiar call, and, when one 

 recognised, is not likely to be mistaken. Mr. Seebohm ah 

 states that it has a second note like " the syllable tra." Thi 

 I have not noticed, but the other resounding note may oftei 

 be heard in our woodlands, though the bird itself will be rai 

 observed. In the spring-time both this Woodpecker and it 

 smaller cousin, D. minor, produce a loud noise by drumming 

 with their bills on the branches or twigs of a tree, and thes 

 vibrating taps are generally supposed to be a signal or call-nc 

 between the sexes. Certainly this noise can be heard at 

 considerable distance. The food of the Great Spotted Woe 

 pecker consists of insects of all sorts, which it procures aft< 

 the manner of its kind by hammering at the bark of a tree ai 

 prising it off. It also feeds on fruit and nuts, acorns, berrit 

 &c. It is the only British Woodpecker which is a migrant 

 and nearly every year considerable numbers cross the oces 

 When I was in Heligoland with Mr. Seebohm, five your 

 D. major were brought to us alive one Sunday morning, having 

 been caught by boys in the potato-fields, where they had 

 dropped to rest, in an exhausted state. 



Nest. None. As with other Woodpeckers, the eggs are laid 

 on chips or powdered wood at the end of a hole, hollowed 

 in nearly every case by the birds themselves. The eggs are 

 laid about the middle of May, and both birds are said to assist 

 in their incubation. 



Eggs. From five to seven in number, sometimes eight being 

 known. Axis, ro-ri5; diam.,
