The adult greater scaup is 39–56 cm (15–22 in) long with a 71–84 cm (28–33 in) wingspan and a weight of 726–1,360 g (1.601–2.998 lb). It has a light blue bill with a small black nail on the tip, yellow eyes, and is 20% heavier and 10% longer than the closely related lesser scaup. [ 16 ]
When male turkeys inseminated female chickens, no hybrids resulted; however, the unfertilised chicken eggs began to divide. According to Olsen, [20] turkey-chicken crosses produced all males. A supposed turkey × pheasant hybrid was reported by Edwards in 1761. [22] A hybrid between a turkey and Ocellated turkey was reported in 1956. [23]
Chickens remained primarily to provide eggs, mostly to the farmer (subsistence agriculture), with commercialization still largely unexplored. Farm flocks tended to be small because the hens largely fed themselves through foraging, with some supplementation of grain, scraps, and waste products from other farm ventures. Such feedstuffs were in ...
A study of female greater prairie-chickens in Kansas found that their survival rates were 1.6 to 2.0 times higher during the non-breeding season compared to the breeding season; this was due to heavy predation during nesting and brood-rearing. [16] One problem facing prairie-chickens is competition with the ring-necked pheasants. Pheasants lay ...
Scaup is the common name for three species of diving duck: Greater scaup, or just "scaup", Aythya marila; Lesser scaup, Aythya affinis;
[34] From 1969 to 2002, the number of family farms dropped by 39%, [35] yet the percentage of family farms has remained high. As of 2004, 98% of all U.S. farms were family-owned and -operated. [ 36 ] Most meat and dairy products are now produced on large farms with single-species buildings or open-air pens.
Hens give the namesake discordant scaup, scaup call; in courtship drakes produce weak whistles. Hens vocalize more often than those of the greater scaup—particularly during flight—but their call is weaker, a guttural brrtt, brrtt. [2] [7] [8]
Tympanuchus comes from Ancient Greek roots and means "holding a drum"; it refers to the membranous neck sacks and the drum-like call of the greater prairie chicken. The two prairie chickens are particularly closely related and look extremely similar. But their taxonomy and the evolutionary relationships of the Tympanuchus is yet to be ...
