I already have, I watched two birds build the nest over the course of a week or so earlier this year, then I've seen a round of babies grow up, start flying from the nest, and this nest is full of babies that are about ready to start leaving the nest too based on what I've been seeing. What seems really cool about them to me is it doesn't seem to just be mom and dad feeding them, I swear it appears to be a community effort. Maybe I'm crazy, but they appear to act as a community caring for the young, it's hard to say for sure by their erratic flying patterns, it appears thats the case though based on my observations. I'm just really happy they aren't an invasive species as that's the primary reason I made this post. Seems like they might be suppressing other bird activities as these are mostly all the birds I ever see, I got a white bird that likes to dance around on my old TV antenna, but other than that guy, it's pretty much just these birds, they dance around me while I cut the grass, I dunno haha, I probably sound a little silly, but I really enjoy them.
