Looks like a nice idea. I don't know birds; do some of them use nests in winter?

Hello Clare,
In this area,where it will get horribly windy and cold in another couple of months, I'm thinking of the stragglers who stay and have chosen not to migrate, like some of the Robins. Lots of Doves and Sparrows stay through through winter. This is for them. I will leave it up till the Spring as well, to see what happens.
Best,
PP

Hi, just saw this older post but if you are still leaving nesting material, try dog hair (if you have a dog, that is!). I've put those big fluffy chunks that come out all over in a suet feeder and it's all gone w/in a day.

Funny, when I used to brush my dog outside, I would pull the hair from the brush, and leave the fluffy clumps on the ground below trees. In the spring I would see nests with white dog fur woven into them. My dog had a terrible shedding problem. I brushed her every single day for over a year, and she still shed.

That is a nice idea! I could do that with the my Little Bluestem grasses next spring provided they grow nicely this year!
I have 4 dogs that shed spring and fall...the birds love all that downy soft fluff :)
