  2. Respirometry - Wikipedia

    en.wikipedia.org/wiki/Respirometry

    Respirometry depends on a "what goes in must come out" principle. [6] Consider a closed system first. Imagine that we place a mouse into an air-tight container. The air sealed in the container initially contains the same composition and proportions of gases that were present in the room: 20.95% O 2, 0.04% CO 2, water vapor (the exact amount depends on air temperature, see dew point), 78% ...

    en.wikipedia.org/wiki/List_of_birds_by_common_name

    In this list of birds by common name 11,278 extant and recently extinct (since 1500) bird species are recognised. [1] Species marked with a "†" are extinct. Contents

  4. Basal metabolic rate - Wikipedia

    en.wikipedia.org/wiki/Basal_metabolic_rate

    BMR is a flexible trait (it can be reversibly adjusted within individuals), with, for example, lower temperatures generally resulting in higher basal metabolic rates for both birds [7] and rodents. [8] There are two models to explain how BMR changes in response to temperature: the variable maximum model (VMM) and variable fraction model (VFM).

    Bird Image Species Family Maximum height Details Rüppell's vulture: Gyps rueppellii: Accipitridae: 11,300 metres (37,100 feet). [1] [2] Vultures use their excellent eyesight to scan the landscape below from a relatively static aerial position. Instead of flying over a larger distance, they use elevation to expand their field of vision. [3]

  7. Emu - Wikipedia

    en.wikipedia.org/wiki/Emu

    As with other ratites, emus have a relatively low basal metabolic rate compared to other types of birds. At −5 °C (23 °F), the metabolic rate of an emu sitting down is about 60% of that when standing, partly because the lack of feathers under the stomach leads to a higher rate of heat loss when standing from the exposed underbelly.

  8. Bee hummingbird - Wikipedia

    en.wikipedia.org/wiki/Bee_hummingbird

    It is a diurnal bird that can fly at 40–48 km/h (22–26 kn; 11–13 m/s), and it beats its wings 80–200 times per second, which allows it to remain stationary in the air to feed on flowers. The bee hummingbird lives up to seven years in the wild, and 10 years in captivity.

  9. Bird measurement - Wikipedia

    en.wikipedia.org/wiki/Bird_measurement

    Bird measurement or bird biometrics are approaches to quantify the size of birds in scientific studies. The variation in dimensions and weights across birds is one of the fundamental sources of diversity among birds, and even Within species, dimensions may vary across populations within species , between the sexes and depending on age and ...
