The fastest animal in flapping horizontal flight may be the Mexican free-tailed bat, said to attain about 160 kilometres per hour (99 mph) based on ground speed by an aircraft tracking device; [24] that measurement does not separate any contribution from wind speed, so the observations could be caused by strong tailwinds. [25] Slowest.
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.
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 ...
The High-Tech Tools Scientists Use to Track Wild Animals Science in recent years has seen an explosion of wildlife tracking-devices that are enabling new insights and scientific breakthroughs.
Infrared sensing snakes use pit organs extensively to detect and target warm-blooded prey such as rodents and birds. Blind or blindfolded rattlesnakes can strike prey accurately in the complete absence of visible light, [13] [14] though it does not appear that they assess prey animals based on their body temperature.

Insectivorous aerial-hawking bats, those that chase prey in the open air, have a call frequency between 20 kHz and 60 kHz, because it is the frequency that gives the best range and image acuity and makes them less conspicuous to insects. [21] However, low frequencies are adaptive for some species with different prey and environments.
These elusive creatures are adept hunters of various prey: fish, frogs, mammals, birds, eggs, reptiles, and amphibians, and they have a penchant for fruits, insects, and forest-floor mushrooms ...
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 ...
