Too Bad About the Neighborhood

We have new birds at our bird feeders.

They are Common Redpolls and Pine Siskins.

They are very pretty birds,
but they are so aggressive that they are keeping the
chickadees, goldfinches and cardinals away.

Our established residents are not happy with the new arrangement.
This waiting in line for dinner is "for the birds!"

I read in my Kitchen Table Bird Book
that the Pine Siskins and Common Redpolls rarely visit,
but when they come, they bring the entire community with them.

I wonder how long they will visit before they are on their way?
Not soon enough, according to my current residents!
