Commercially grown birdseed.

[pugwash52]

So much seed is grown commercially for us to feed wild birds in our garden , but how do they keep the birds from eating it before it is harvested?

Good question pugwash, i would like to think that its gwown on such a large scale that they allow for some loses, or maybe the crops are covered with nets ?

I dont know but I try not to be cynical..

I think logman is essentially correct, but, additionally, many seeds used as bird food are not eaten by many birds in the wild... by that I mean, one of the primary sources of wild bird food here in the U.S. are sunflowers. In the wild, they are eaten by only a few varieties of birds, but once shelled and often chipped, they are appreciated by many species. Same holds true with other types of seeds...
