Spring Goldfinches

I'm not sure why this year and no other years that I can remember, but as it has warmed up this spring, I suddenly have swarms of goldfinches perching on my home office windows, and pecking at the glass. Odd. But nice.

Goldfinch friends

They are numerous, persistent, and don't scare off easily.

At one point a couple days ago I had 5 at one time. Very odd indeed...
