Playing With a Feather
When was the last time you played with a feather?
I found this one sticking out of a patch of grass; I think it once belonged to a pigeon. So I picked it up and have been playing with it.
Close-up, the structure is beautiful – delicate and perfectly stripy. I really wanted to hear the noise it makes when two stripes are pulled apart. It’s a sound I remember from childhood. It’s rather gentle, yet distinctive, very quiet and very lovely.
Each stripe is actually a very thin hair-like structure which is joined to its neighbouring stripes by incredibly tiny hooks. It works a bit like velcro.
And today, through my physical examination of this feather I discovered something new!
I had always thought that once the stripes were pulled apart it was impossible to put them back together, meaning that the feather was irreparably damaged and fairly useless for flying – a terrible state of affairs if it’s still being used by a bird.
But this is not the case at all. They stick right back together again, they just need to be brought together at the right angle.
I feel very relieved to have discovered this, and have been happily pulling the stripes apart and sticking them back together ever since!
Kudos on your “thought that once the stripes were pulled apart it was impossible to put them back together” confession; likewise, I was in my 40s before I realised that the hit beat combo from Liverpool were the BEATles, having always thought of the Fab Four as the BEETles.
A good deal of avian preening is dedicated to zipping back together those feathery barbules that have become separated by the vortices that flight creates as a byproduct.
