I was trekking across the scrub recently and encountered a feather snagged on a Bumelia.
I'm not totally sure what bird species shed it. It appears to be a larger species, though. A Great Horned Owl hunts here. So do hawks. I'll have to run it by someone who knows more about feather identification.
Usually I find wing or tail feathers, which are a little easier to sort out. This is more of a challenge, but worth sharing.
