This Robin, for example. He turned up in our front yard, and the kids called me over to watch with him. We did a much better job of observing him - Hero spontaneously started using some of the techniques we've learned recently - and it was really cool to see how much more we could notice about him than what we did before.
We saw him run around the grass a while looking for food. They especially like the spots on his back, and thought that they look like a Creeper's face, so we dubbed him "Creepy". Which cracks me up, because he's so not creepy.
In addition to noticing his coloring, we also got to watch him eat, and (we think) mate -- with two different birds! And the kids were much more aware of the way that he moves: he was doing more running than the hopping that many of the other birds in our yard do. It was really interesting to watch both the bird, and also my kids as they applied the things that we've been talking about and learning over the past little while. I think that was my favorite part: seeing the growth that we're all having in this area right now.
