White-tailed Deer near Schiff Lake in The Colony, Texas.
Here is what Wikipedia has to say about White-tailed Deer:
The white-tailed deer is highly variable in size, generally following Bergmann’s rule that the average size is larger further away from the Equator. North American male deer (also known as a buck or stag) usually weighs 60 to 130 kg (130 to 290 lb) but, in rare cases, bucks in excess of 159 kg (350 lb) have been recorded. Mature bucks over 400 pounds are recorded in the northernmost reaches of their native range, specifically, Minnesota and Ontario. In 1926, Carl J. Lenander, Jr. took a white-tailed buck near Tofte, MN, that weighed 183 kg (400 lb) after it was field-dressed (internal organs removed) and was estimated at 232 kg (510 lb) when alive. The female (doe) in North America usually weighs from 40 to 90 kg (88 to 200 lb). White-tailed deer from the tropics and the Florida Keys are markedly smaller-bodied than temperate populations, averaging 35 to 50 kg (77 to 110 lb), with an occasional adult female as small as 25.5 kg (56 lb). White-tailed deer from the Andes are larger than other tropical deer of this species and have thick, slightly woolly-looking fur. Length ranges from 95 to 220 cm (37 to 87 in), including a tail of 10 to 36.5 cm (3.9 to 14.4 in), and the shoulder height is 53 to 120 cm (21 to 47 in). Including all races, the average summer weight of adult males is 68 kg (150 lb) and is 45.3 kg (100 lb) in adult females
