Red squirrels are more forgetful, and often forget where food is hidden.īuried nuts and seeds that don’t get stolen or eaten usually grow into trees and shrubs when the weather warms up. Gray squirrels often remember where they hide food and come back later to eat it. This keeps the rest of the food stockpile and squirrel nest safe. If a food thief finds a buried nut, the thief thinks that’s the whole food stash and moves on. Squirrels scatter hoard for a few reasons, but one of them is to trick food thieves in winter. This behavior is called scatter hoarding. They bring this food back and bury it around their territory, close to their nest. In fall, squirrels move around their range to collect as much food as they can. But they also have a range, or a much larger area, that they will explore during the day to look for food. Squirrels are territorial and have an area around their nest that’s theirs, and they will fight to defend it and stop other squirrels from moving into this area.

Planting trees and protecting our woods is crucial for wildlife. You can help red squirrels and other native species by caring for their habitat. If you're responsible for any trees, make sure you check them carefully for nests before carrying out any maintenance work, especially during breeding season. Only leave a small amount every few days though as it’s important they still look for natural food sources. Food sources are scarcer in spring and summer, so putting out a mix of nuts, seeds, fruit and veg can be welcome. Offer food and shelterīuying or making a squirrel box or feeder is a great way to help reds, and sizing the entry hole carefully will mean larger grey squirrels can’t get in.
