Here are some videos that were captured just today (May 5th).
In this one you can see just how big they are. You can't see them all in this video, but I promise there are 5 little birds crammed into this nest:
In case you didn't believe me, here is a good view of all 5 of them in the nest as they jockey for a fresh position:
Finally, I think this is a good example of how close they are to leaving the nest. Lots of wing flapping going on in this video, getting those little flight muscles warmed up and primed. There's also some wing extending and tail bobbing going on here:
We'll have the camera going bright and early for the next few days in hopes of catching them when they leave (they took off in the morning last year, right before we left for work). I'll keep you posted with the news!
