Eastern Bluebird

Notes:

I feel blessed to share the yard with these guys every year. I look forward to seeing them each spring.

I've read that volunteers take care of a number of bluebird houses in a nearby park. Maybe these guys are an offshoot of that group.

Most of the trees in my yard are still pretty small. But some of the neighbors have large native trees that probably produce a good number of caterpillars. I'm working on adding many more native plants. Together, they should help make a stable supply of food for baby bluebirds.

I think the environment should be put in the category of our national security. Defense of our resources is just as important as defense abroad. Otherwise what is there to defend?
