Red Squirrel’s Winter Coat

2-20-14 winter red squirrel IMG_0220There is a marked seasonal difference in the Red Squirrel’s appearance due to its two annual molts (spring and fall). In the winter, a broad rusty-red band extends along its back, from its ears to the tip of its tail. The Red Squirrel’s thicker winter coat also includes ear tufts, which no other species of squirrel in the Northeast possesses. Come spring, when the squirrel sheds again, it loses its ear tufts and its new coat is closer to an olive-green color than red.

    What a great shot of the red squirrel Mary. The detail is beautiful.
    I know the challenge’s involved getting the little buggers to stand still long enough to get a shot off! BF…

    I have a few grey squirrels in my back yard who have beautiful full coats on their bodies, but no hair on their tails (like rats). Do you know what causes this?

    • I wish I could give you an explanation, Suzanne, but I don’t have one. If anyone reading this does, it would be great to hear from you. (Mange and the start of spring shedding might contribute, but those are total guesses.)

    • Interesting! I’ve seen the same fox several times this winter, and it has the same problem you describe: a naked, rat-like tail. Hope these critters grow some new fur!

  5. Does that mean that the red hairs are longer, what are referred to as ‘guard hairs’? Great shot of Sparky!

  6. To be honest, I’m not sure, Eliza, but probably red squirrels, like a lot of mammals, have both guard hairs as well as underfur, so yes, I guess you could call them guard hairs as they protect the underfur and skin from water, snow, etc., which guard hairs do. Talk about a run-on sentence!
