  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/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 ...

  6. European robin - Wikipedia

    en.wikipedia.org/wiki/European_robin

    The larger American robin (Turdus migratorius) is a much larger bird named from its similar colouration to the European robin, but the two birds are not closely related, with the American robin instead belonging to the same genus as the common blackbird (T. merula), a species which occupies much of the same range as the European robin. The ...

  7. 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).

  8. Java sparrow - Wikipedia

    en.wikipedia.org/wiki/Java_sparrow

    The Java sparrow (Lonchura oryzivora; Japanese: 文鳥, bunchō), also known as the Java finch, Java rice sparrow or Java rice bird, is a small passerine bird.

  9. Barn swallow - Wikipedia

    en.wikipedia.org/wiki/Barn_swallow

    Barn swallow nestlings have prominent red gapes, a feature shown to induce feeding by parent birds. An experiment in manipulating brood size and immune system showed the vividness of the gape was positively correlated with T-cell–mediated immunocompetence, and that larger brood size and injection with an antigen led to a less vivid gape. [71]
