Veer! Ilahay! You’re back!
Kya and Tierra were all over the nest area today, but didn’t leave it. Their siblings returned and hung out with them, joined at times by a parent, until the late evening, when Veer flew off again.
I asked the peregrine group if that could damage the fledgling’s feathers, given my experience with the bleaching effect of bird poop even when washed off right away and Stephanie‘s experience once with it actually weakening the fibers in her yarn. I was assured that birds’ feathers have a protective coating on them and not to worry.
So I guess it doesn’t harm them after all. Just makes them easy to spot.
