House Finch
My area has had a sharp decline of House Finch, I suppose due to this disease that I have witnessed in my area. I’ve been looking for a short, easily understood article to repost to my local area on Nextdoor.one that brings a quick understanding of what it does, looks like, and the importance of taking down old feeders and cleaning feeders often and properly. Can you please provide such and article? And a closeup photo of an infected bird in late stage?
