I have a big problem with crows in my bird feeder, how do I get rid of them, without taking the food away?

I do not want to take the bird feeder away because I like to watch the birds, but the crows and ravens now, scare all the other poor birds and eat all the food. Help please!I have a big problem with crows in my bird feeder, how do I get rid of them, without taking the food away?
Change your feeder for one that the larger birds can't use.I have a big problem with crows in my bird feeder, how do I get rid of them, without taking the food away?
Instead of laying your bird food out on a table, pack it into nylons (pantyhose) with some holes strategically poked through. Then hang the nylons into hard to reach spots which the crows are too big to get at. Your other (smaller) birds will still be able to get at the food.
get a scarecrow.
