This is a great time of year to see mating chases of red squirrels in the woods. You can see from this fabulous image by James A Moore of Black Isle Photography Hides that you can seem some remarkable acrobatics and some very fast moves!
Red squirrels will also start to repair or build their dreys in preparation for raising their families of kittens. The female will wean 3-5 kittens in the drey which is located high up the tree and sometimes along a branch. They usually build new dreys each year as the winter storms usually damage last year’s dreys. The dreys are made up of sticks, twigs, leaves and lined with soft moss and feathers.
You can see from this video that they make some extraordinary noises too when they are chasing each other!
