Ruffed Grouse Nostril Feathers

12-16-14 ruffed grouse nostrils IMG_2376Ruffed Grouse have adapted to cold winter months in a number of ways, from growing “snowshoe” pectinations on their toes to having their legs covered with fine feathers. Equally effective are the feathers covering a grouse’s nostrils, which are thought to heat cold air as the bird breathes in. (Thanks to Sara and Warren Demont for photo op.)

  1. I’m not sure whether your “which” refers to feathers or nostrils. The feathers can’t heat the air being breathed in, since I doubt they have active blood flow in them, but the nostrils with their blood flow can and the feathers would reduce heat loss at that point.

    • Yes, I believe the feathers just slow the air down, certainly they don’t heat it!

    Imagine growing snowshoes on your feet for winter – wish Petunia could do that!

    Hope all is well up there. The weather sounds disappointing though. Are we going to have a white Christmas?! Chilly here, but there are pansies in bloom. XXOO

    I found a ruffed grouse in my dooryard garden a few years ago. Had no idea what it was, since I’d only ever seen them in motion! It was such an amazing feeling to hold its body in my hands. Eventually I took a few photos and gave it a proper burial.
