Many birds, especially those that nest in cavities, are known to produce a snakelike hissing sound that may help deter predators at close range. [ 44 ] Some cave-dwelling species, including the oilbird [ 45 ] and swiftlets ( Collocalia and Aerodramus species), [ 46 ] use audible sound (with the majority of sonic location occurring between 2 and ...
Thus, lateralization is possible, with muscles on the left and right branch modulating vibrations independently so that some songbirds can produce more than one sound at a time. [3] Some species of birds, such as New World vultures, lack a syrinx and communicate through throaty hisses. Birds do have a larynx, but unlike in mammals, it does not ...
Vocal Bird anatomy: Birds produce sounds through the air that passes through the Syrinx, which is shown close up in the bottom right. In order for birds to produce sound, they use an organ located above the lungs called the syrinx , which is composed of tracheal rings, syringeal muscles, Tympaniform membrane, and internal bony structures that ...
Why do migrating birds fly at night? Ms Sheridan said you can often hear geese flying over at night at this time of year, and called the "honking" noise they make "quite spooky".
Increased efficiency of sound production is important, as some frogs may produce calls lasting for several hours during mating seasons. [7] The New River tree frog (Trachycephalus hadroceps), for example, spends hours producing up to 38,000 calls in a single night, which is made possible through the efficient recycling of air by the vocal sac.

Bats and birds are taken occasionally as well. The great potoo takes advantage of the night and its natural camouflage by sitting on an exposed perch to wait until some prey flies by, at which point it darts out towards the prey and returns to the branch with it. Very often birds of this species will use the same hunting perch nightly. [14]
How do birds get their colors? Understanding bird coloration combines biology and physics. There are two primary ways that birds get their color: pigmentation and the physical structure of the ...
There are many birds that are active nocturnally. Some, like owls and nighthawks, are predominantly nocturnal whereas others do specific tasks, like migrating, nocturnally. North Island brown kiwi, Apteryx mantelli [1] Black-crowned night heron, Nycticorax nycticorax [1] Short-eared owl, Asio flammeus [1] Long-eared owl, Asio otus [1]
