Why Do Squirrels Squawk in the Tree?

Red squirrels are very vocal animals.

The most common species of squirrel in North American is the Red Squirrel. These nest in trees, most commonly in forested areas, but can also live in garden trees. When new animals start to appear in the garden they are accompanied by a new range of noises, which they make as part of mating, defense and general talking. Red squirrels are no different; they emit a wide range of sounds in different situations.

Birds

If you can hear squawking from a tree where there are squirrels, there is a good chance it is not squirrels. Birds may also be nesting in the tree and trying to fend off squirrels from eggs or chicks. Some squirrels species, along with other tree-climbing rodents, will steal eggs for food. When birds and squirrels are in the same area there is also competition for food sources, such as nuts and seeds.

Warning predators

As with other animals, squirrels are at their most talkative when a predator is threatening its territory. Red squirrels will make a squeaking sound when agitated, commonly when a predator -- like an owl -- is seen. This can then be followed by a barking or chirping noise. If other rodents or non-predatory animals are in its territory, squirrels chatter or rattle. This noise is also used as a recognition signal.

Growls

Along with barking, squirrels also make other dog-like noises such as growls when they are fighting or chasing away other squirrels during mating season or animals encroaching on thier territory.

Screeches

Squirrels will sometimes screech and this can be for a couple of reasons. First, it is another way of defending its territory. This is also the kind of noise a squirrel makes when it is by itself.

Mating Calls

During mating season, which is during the early spring, male squirrels will emit a buzzing noise when approaching a female.
