Mama didn’t lay an egg yesterday or today. We are still sitting on three. It was a gray day with thunderstorms passing through this afternoon. I wondered what the bluebirds were doing during that gale and sideways rain. Our cockatiel Peaches didn’t like it. She kept calling me when the lightning was flashing and thunder crashing.

The fledglings are no longer babies, so I’m going try to quit calling them such. They are now 
juvenile bluebirds, so I’ll probably just refer to them as juvies. They visited the yard this morning. The light was so poor I didn’t get the quality pics I wanted, but you take it like you find it photographing wildlife. They made attempts to come down to the mealworm feeder, but would shy away when they saw me sitting on the patio.

A minor altercation occurred when the male mockingbird decided the bluebird box would be a good place to perch. Mama was inside at the time. Apparently Daddy was on the roof. I saw a flash of blue hit the mocker hard enough I heard it. The mockingbird went to the ground underneath the box and Daddy was on him. Mama jumped into the fray, too. Then the mockingbird flew to the Live Oak tree on the other side of the yard and traded insults with the scolding bluebirds. But in general they seem to be tolerating each other fairly well.
The male mockingbird. Looks fierce if you are a bluebird.
This morning there was another adult male bluebird sitting in the tree with Daddy. I thought it unusual that Daddy didn’t attack him. Male bluebirds are extremely protective of their territories. Maybe one of last year’s offspring? I don’t know and I don’t think being related would matter at this point. A female Painted Bunting visited one of the feeders today along with twenty or so other species.
Bluebird Diary 
Mockingbirds can be fierce in nesting season! Glad that there hasn’t been much conflict (as long as neighbors respect each others’ houses).
I had a mockingbird at my old house that would chase the neighbor’s cat and dive bomb me on the riding mower. He was definitely not scared of anything. So far these are tolerating us. They are nervous about entering the nest with new material when I’m on the patio, but they are going to have adapt. The bluebirds have.
We have a mockingbird that chased a squirrel all over our yard, and up and down a tree. The bird won.
They are aggressive. These have gotten used to me. I get a kick out of watching them spar with the crows that are used to eating here.
