The last time I was at my parent's house, my Mom told me I should take my camera, go outside, and try to capture a pair of bluebirds nesting in her birdhouse at the end of the driveway. I was up for it, obviously :)
After about ten minutes, I had some shots of small blurry birds. Then, I noticed that Dad had come outside and was getting his tripod out of his truck. "Hmmm, maybe he's going to bring that over here?" I wondered. Yep, here he comes, the tripod attached to his camera, the camera attached to a supermondo lens. But the birds weren't cooperating too well, and it was cold, and Dad grew impatient. I was more than happy to take over the operation from him. This is the only picture I have where both male and female are in the shot at the same time.
Judging by the number of caterpillars going in, and the amount of "waste" carried out, the happy couple's eggs had hatched and hungry mouths were being fed.
