Thanks for your explanation. It certainly makes sense. I'm getting
ready to head out right now and see what's out and about in this
storm. The Purple Finch has moved on, as we haven't seen it in
several weeks now.
I posted a photo yest. in the photo section of a Black-capped and
Mountain Chickadee together on my suet feeder - I'm kinda proud of
it. This is the first year we've had both together at our place.
