repeated several times, and at a distance sounds somewhat like that 

 of a Jay (H.F.W.).

 and makes a scanty nest of juniper bark and willow-fibre, but does 

 not use moss, hair or feathers. Eggs. — Usually 7 or 8, occasionally

 49 eggs, 15.2x12.1 mm. Breeding-season. — About mid-May in 

 south Scandinavia and a week later in the north. Incubation. — 

 Probabl}' similar to that of British race.

Distribution. — England. — One, Tetbury (Gloucester), March, 1907. 

 Also thought to have been seen at Weh^yn (Herts.), Jan. 12, 1908 

 [ut supra).
