In pursuit predation, predators chase fleeing prey. If the prey flees in a straight line, capture depends only on the predator's being faster than the prey. [40] If the prey manoeuvres by turning as it flees, the predator must react in real time to calculate and follow a new intercept path, such as by parallel navigation, as it closes on the ...
Crepuscular, a classification of animals that are active primarily during twilight, making them similar to nocturnal animals.; Diurnality, plant or animal behavior characterized by activity during the day and sleeping at night.
Predators may identify their prey by sound as well as sight; mimics have accordingly evolved to deceive the hearing of their predators. Bats are nocturnal predators that rely on echolocation to detect their prey. [32] Some potential prey are unpalatable to bats, and produce an ultrasonic aposematic signal, the auditory equivalent of warning ...
The various species have many predators: while forest hedgehogs are prey primarily to birds (especially owls) and ferrets, smaller species like the long-eared hedgehog are prey to foxes, wolves, and mongooses. Hedgehog bones have been found in the pellets of the Eurasian eagle owl. [15] In Britain, the main predator is the European badger.
Fishers are generalist predators. Although their primary prey is snowshoe hares and porcupines, they are also known to supplement their diet with insects, nuts, berries, and mushrooms. They have been observed eating small apples during winter. Since they are solitary hunters, their choice of prey is limited by their size.
[77] [154] Divers, diving ducks, penguins and auks pursue their prey underwater, using their wings or feet for propulsion, [68] while aerial predators such as sulids, kingfishers and terns plunge dive after their prey. Flamingos, three species of prion, and some ducks are filter feeders. [155] [156] Geese and dabbling ducks are primarily ...
Experiments on blue jays suggest they form a search image for certain prey.. Visual predators may form what is termed a search image of certain prey.. Predators need not locate their host directly: Kestrels, for instance, are able to detect the faeces and urine of their prey (which reflect ultraviolet), allowing them to identify areas where there are large numbers of voles, for example.
Blue jays can also copy the cries of local hawks so well that it is sometimes difficult to tell which it is. [43] Their voice is typical of most jays in being varied, but the most commonly recognized sound is the alarm call, which is a loud, almost gull -like scream.
