How long does it take for birds to find a newly hung bird feeder?

I live in Vermont and I have just put up a bird feeder at my new apartment. I live in a rural area so there are lots of trees etc. for the birds to live in.How long does it take for birds to find a newly hung bird feeder?
usually only takes a day or 2 make sure you feeder is near some small trees or bushes for cover. birds like to be able to hide a bit if they can.How long does it take for birds to find a newly hung bird feeder?
my dad always told me to hang new bird feeders when its cold outside (and if there is snow on the ground its even better)... so, i am betting that they will find them right after you have a cold wave
It seems like birds can smell food (maybe they can). I have a feeder hung from a tree, a freestanding feeder on a pole, a Finch feeder bag and two hummingbird feeders. As soon as they are refilled in the spring, I have birds all over the place.
not to long but i guarentee the squirrels will find it first lol
Mix some cheese or fat with the feed. you get lot of bird's pretty soon.
