Kleiber found that an organism's basal metabolic rate could be predicted by taking 3/4 the power of the organism's body weight. This finding was noteworthy because the inversion of the scaling exponent, between 0.2 and 0.33, also demonstrated the scaling for both lifespan and metabolic rate, and was colloquially called the "mouse-to-elephant ...
Kleiber's plot comparing body size to metabolic rate for a variety of species. [1]Kleiber's law, named after Max Kleiber for his biology work in the early 1930s, states, after many observations that, for a vast number of animals, an animal's Basal Metabolic Rate scales to the 3 ⁄ 4 power of the animal's mass.

In that book, Ackerman posits that, contrary to popular metaphors such as "bird brained," birds are actually quite intelligent and think in complex ways. [2] Called a "peppy survey of the science of bird intelligence" by The Guardian, the book was a New York Times best seller in 2017. [3] She followed up on this idea in her 2020 book The Bird ...

New York City is a key factor of birds adjusting their songs in response to loud background noises which results in low frequency in their songs. Additionally, some birds engage in mutualism , contributing to plant pollination , an interaction between the birds of the New York City recently enforced green spaces [ 14 ] as habitats, [ 15 ...
