Canada's annual average temperature over land has warmed by 1.7 °C (3.1 °F), with changes ranging from 1.1 to 2.3 °C (2.0 to 4.1 °F) in various regions, since 1948. [4] The rate of warming has been higher across the North and in the Prairies. [ 4 ]
The typical height of an adult human is between 1.4 and 1.9 m (4 ft 7 in and 6 ft 3 in), although this varies significantly depending on sex, ethnic origin, and family bloodlines. [ 239 ] [ 240 ] Body size is partly determined by genes and is also significantly influenced by environmental factors such as diet , exercise, and sleep patterns .
Prevalence of obesity in the adult population, top countries (2016), the United States has the tenth highest rate in the world. The CDC defines an adult (a person aged 20 years or greater) with a body mass index (BMI) of 30 or greater as obese and an adult with a BMI of 25.0 to 29.9 as overweight. [4] Obesity in adults is divided into three ...
Temperatures in March and April were slightly lower than in autumn at 39.6 to 51.3 °F (4.2 to 10.7 °C). Indiana bat populations increased over time in hibernacula that had stable midwinter temperatures averaging 37.4 to 45.0 °F (3.0 to 7.2 °C), and declined in hibernacula with temperatures outside this range.

A steer. The Texas Longhorn is an American breed of beef cattle, characterized by its long horns, which can span more than 8 ft (2.4 m) from tip to tip. [4] It derives from cattle brought from the Iberian Peninsula to the Americas by Spanish conquistadors from the time of the Second Voyage of Christopher Columbus until about 1512. [5]
An adult groundhog can eat more than 1 lb (0.45 kg) of vegetation daily. [37] In early June, woodchucks' metabolism slows, and while their food intake decreases, their weight increases by as much as 100% as they produce fat deposits to sustain them during hibernation and late winter. [ 38 ]
The slowing of the metabolism is accompanied by a decreased heart and respiratory rate, as well as a drop in internal temperatures, which can be around ambient temperature in some cases. For example, the internal temperatures of hibernating Arctic ground squirrels can drop to −2.9 °C (26.8 °F); however, the head and neck always stay above 0 ...
The frigatebird's high speed is helped by its having the largest wing-area-to-body-weight ratio of any bird. 8 Rock dove (pigeon) 148.9 km/h (92.5 mph) [15] Flight Pigeons have been clocked flying 92.5 mph (148.9 km/h) average speed on a 400-mile (640 km) race. 9 Spur-winged goose: 142 km/h (88 mph) [16] Flight 10 Grey-headed albatross
