I got up a little late this morning so the bird population at the Green House had to wait for their breakfast. I had just put the feast out and by the time I got back in the house my deck was covered with hungry birds. And to my surprise and complete joy, among them was Papa Bluebird and four of his babies. Mama showed up a bit later. The little ones had their mouths open and Papa was feeding as fast as he could. I was watching from my kitchen widow, where my computer is conveniently placed, and they were no more than 10 feet away. Needless to say, not much got done around here this morning.
Bluebirds are not seed eaters so if you want to attract them usually you have to buy meal worms. Other than that you can plant bluebird friendly shrubs and vines, which is a good thing to do, and I have planted several but have never noticed if the bluebirds are partaking. Quite by accident I found out they will eat suet. One morning about two years ago I happened to be looking out my front window and saw a male bluebird trying to get suet from the suet feeder I had put out for the woodpeckers. I noticed there were two little ones waiting impatiently on the power line just above. Papa bluebird was having a tough time, bluebirds are not clingers. I decided to chop up a suet cake and place it on a feeder tray, my version a clay pot bottom on a plant stand. It worked. Since then I have been placing chopped suet on my deck rail, not a good idea if you care about a clean deck, and I've had bluebirds ever since. They prefer the no melt variety, I buy orange or peanut, whichever I can find, but they will eat the regular kind, too.
I love all my birds but there's something special about bluebirds. Their population was in decline but they are now making a comeback thanks to a "network of birding enthusiasts" and backyard bird nuts like me.
