Even if a predator may wish to eat its prey, locomotive animals may be extremely difficult to catch. Animals living in groups have increased vigilance, and even solitary animals are capable of rapid escape when needed. Even if it does make a capture, its prey may attract competing predators, giving it a chance to escape in the struggle.
Much of the communication between predators and prey can be defined as signaling. In some animals, the best way to avoid being preyed upon is an advertisement of danger or unpalatability, or aposematism. Given the effectiveness of this, it is no surprise that many animals employ styles of mimicry to ward off predators. Some predators also use ...
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 ...
Zoologists have repeatedly compared aggressive mimicry to the wolf in sheep's clothing strategy of fable, [42] including when describing jumping spiders, [2] [3] lacewings, [43] ant-mimicking aphids, [44] hemipteran bugs mimicking chrysomelid beetles, [45] bird-dropping spiders, [4] orchid mantises, [4] cichlid fish, [46] [47] and the zone ...
Animals rely on signals called electrolocating and echolocating; they use sensory senses in order to navigate and find prey. [22] Signals are used as a form of commutation through the environment. Active signals or other types of signals influence receivers behavior and signals move quicker in distance to reach receivers.
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 ...
Birds may also have a role in the dispersal of propagules of plants and plankton. [117] [118] Some predators take advantage of the concentration of birds during migration. Greater noctule bats feed on nocturnal migrating passerines. [23] Some birds of prey specialize on migrating waders. [119]
The imitating species is called the mimic, while the imitated species (protected by its toxicity, foul taste or other defenses) is known as the model. The predatory species mediating indirect interactions between the mimic and the model is variously known as the [signal] receiver , dupe or operator .
