In experimental settings, animals have demonstrated perceptual switching: visual predator would form a searching image of the most abundant cryptic prey species in their environment; as the species is more predated, its number would decrease and the search image for that species would be less useful to the predator; the predator would then ...
Animal aerial locomotion can be divided into two categories: powered and unpowered. In unpowered modes of locomotion, the animal uses aerodynamic forces exerted on the body due to wind or falling through the air. In powered flight, the animal uses muscular power to generate aerodynamic forces to climb or to maintain steady, level flight.
Animal navigation is the ability of many animals to find their way accurately without maps or instruments. Birds such as the Arctic tern , insects such as the monarch butterfly and fish such as the salmon regularly migrate thousands of miles to and from their breeding grounds, [ 1 ] and many other species navigate effectively over shorter ...
Although the term "bird of prey" could theoretically be taken to include all birds that actively hunt and eat other animals, [4] ornithologists typically use the narrower definition followed in this page, [5] excluding many piscivorous predators such as storks, cranes, herons, gulls, skuas, penguins, and kingfishers, as well as many primarily ...
Tracking in hunting and ecology is the science and art of observing animal tracks and other signs, with the goal of gaining understanding of the landscape and the animal being tracked (the "quarry"). A further goal of tracking is the deeper understanding of the systems and patterns that make up the environment surrounding and incorporating the ...
A cheetah exhibiting pursuit predation. Pursuit predation is a form of predation in which predators actively give chase to their prey, either solitarily or as a group.It is an alternate predation strategy to ambush predation — pursuit predators rely on superior speed, endurance and/or teamwork to seize the prey, while ambush predators use concealment, luring, exploiting of surroundings and ...
With Friday night expected to be the chilliest of the latest cold snap to grip the UK, photographers from the PA news agency have taken a look at how animals are coping in the snow and freezing ...
Members of this group have also been called "hawk-buzzards". [6] The proposed new genera Morphnarchus, Rupornis, and Pseudastur would be formed from members of Buteo and Leucopternis. [7] Members of the "Buteogallus group" are also called hawks, with the exception of solitary eagle species. Buteo is the type genus of the subfamily Buteoninae.
