Yes, wild birds can eat cranberries. Just last week, I put out some on my feeder and on the floor, and some birds eat it, and the squirrels and chipmunks all gobble up the rest on the floor.
Most birds in the wild eat a wide variety of nuts, berries, and small insects, so yes, they do eat cranberries.
Yes
sometimes they will
There are lots of human foods you can feed wild birds, such as bread crumbs, sunflower seeds, chopped nuts and fruits (such as apples and pears), and raisins. I even have all types of birds that fly down to my dog's food bowl on the patio and eat the dry dog food, but the kinds with smaller pieces are much easier for them to eat. Anything that is raw and unprocessed is OK.
Yes they sometimes eat.

Don't feed birds cookies, it's not good for them. There are many things you can feed them. Sunflower, safflower seeds. Millet and milo seed. Nectar in hummingbird feeders. Suet. Orange slices, and raisins.
Cranberries are not a part of any animals primary food source but a variety of animals occasionally eat them such as humans, birds, rabbits, squirrels, chipmunks, mice, grouce and bears.
