Note 78 — Chapter XIII

Richardson, on Tetrao umbellus, ‘Fauna Bor. Amer.: Birds,’ 1831, p. 343. L. Lloyd, ‘Game Birds of Sweden,’ 1867, p. 22, 79, on the capercailzie and black-cock. Brehm, however, asserts (‘Thierleben,’ &c., B. iv. s. 352) that in Germany the grey-hens do not generally attend the Balzen of the black-cocks, but this is an exception to the common rule; possibly the hens may lie hidden in the surrounding bushes, as is known to be the case with the grey-hens in Scandinavia, and with other species in N. America.
