Why birds eat so much

As many of you have noticed, birds have been attacking the feeders like there is no tomorrow. And there won't be if they don't bulk up now to prepare for a harsh Michigan winter or a long journey south. Birds change into a “superbird” state when their internal clock is triggered by shorter days and cooler weather at the end of summer.

Right now a bird needs to increase their fat reserves by as much as 1-10% per day. This feeding frenzy is called hyperphagia. In human terms, this would mean I would have to gain 12 pounds per day. That gives "eats like a bird" a whole new meaning. But remember that their fat increase is vital for the extreme energy required to survive the coming months.

To help the birds, you can feed them high energy, high fat foods. Wild Birds Unlimited is dedicated to offering fresh, top-quality seed. Our no-waste bird seed blends are made from 100% edible seed and have been exclusively formulated for the feeding preferences of our local birds. No cereal fillers—just fresh, high-quality seed your birds will love.
