Squirrels can cache as many as 3,000 nuts each season, but remembering where all the nuts are stored seems impossible. Unlike most small mammals whose brains shrink during winter due to reduced ...
A study reveals the first evidence of California squirrels eating voles. Experts explain why this phenomenon is critical to future behavioral discoveries in animals.
The observations of California ground squirrels engaging in "carnivorous behaviors" were all recorded this year. About 42% of the 74 interactions witnessed between June and July involved "active ...
Humans have also been known to eat rock squirrels, but can also view them as pests, resulting in lethal and nonlethal removal. The rock squirrel displays a variety of antipredator behaviors. When close to a snake, they make menacing movements and even throw debris at the snake. They often feed, rest, and sunbathe in trees, high rocks, and stumps.
When squirrels were almost completely eradicated during the Industrial Revolution in New York, they were later re-introduced to "entertain and remind" humans of nature. The squirrel blended into the urban environment so efficiently that when synanthropic behavior stops (i.e. people do not leave trash outside during particularly cold winters ...
This squirrel has become desensitized to humans. The distance between the squirrel and the camera was less than 18 in (46 cm). Once established in a nest, squirrels ignore fake owls and scarecrows, along with bright flashing lights, loud noises, and ultrasonic or electromagnetic devices. However, squirrels must leave the nest to obtain food and ...
A western gray squirrel eating pine seeds from a pine cone. Squirrel nests are called dreys and can be seen in trees, built from sticks and leaves wrapped with long strands of grass. There are two stick nest types made by the western gray squirrel: the first is a large, round, covered shelter nest for winter use, birthing, and rearing young.
A study conducted in 1990 of black and gray morphs of the eastern gray squirrel concluded that there was no major difference in behavior between the morphs. [20] The same study also found no difference between the morphs when reacting to either a human or canid predator. [21]
