At his fourth feeder he went to some trouble to supply peanut bits which we had read were popular with many birds and especially to bluebirds. No bird goes near them, and even the omnivorous squirrels, who raid whenever and wherever they can, avoid the peanut bits as though confronted with a noxious substance. Nor is the raccoon interested. I have never used peanuts and have no experience with them. Some quick research indicates that peanuts may be eaten by titmice, chickadees, jays, and woodpeckers.
Peanuts spoil more readily than other bird foods.
Check the smell and taste of some pieces. Every so often Jake fluffs his tail and stretches his neck and the squirrels retreat another 10 feet or so. On the morning of April 28, as I was driving to work, a mother Canada goose was showing off four fuzzy little goslings. Those were the first I've seen. I assured her that they were.
