Breeding Season Males: During the breeding season males season male and female salamanders are attracted to each other by their sense of smell. It is apparent that the skin of the females possesses definite odors which attract the males, while the males have scent glands located at the base of the tail and on the under side of the head to attract the females.
Grebes are 9 to 29 inches (23-74 cm) long. e males are usually larger than the females, : the sexes are alike in coloring. They are ally gray, brown, or black above; most are ite below with a white bar (speculum) on the )er surface of the wing. Brighter body plu-ge and elaborate head plumes are present dur-the breeding season males season.
As with fox, mink, and chinchilla, nutria became an item for breeding season males-stock promoters. In the early 1960's, however, the ballyhoo subsided and the raising of nutria settled down to a serious occupation. The advantage of farm-bred nutria, as with other ranched animals, is the ability to produce uniform colors and qualities which facilitate marketing.
breeding season males and Pelting.—The usual breeding season males season for mink is early March, when the females enter their estrous cycle. Mink reach sexual maturity during the first year, at the age of about 10 months. There is only one breeding season males season during the year. A widely practiced breeding season males system is to mate each female twice at an interval of 7 to 10 days. An analysis of ranch data shows better production obtained from those animals mated twice. |
