Trees & birds

Recently walked down the street in NYC and noticed that a tree was chirping. A lot. I looked up and there were little brown chicks throughout the tree, each was chirping. Like a playground full of young children, a beautiful high pitched collage.

Trees are amazing: most trees & plants leaves will wilt in response to drought. Why? So that the leaf has less surface area for sun absorbtion. How does that relate to water? Because water for the most part gets to the leaves via the roots, replenishing what the sun dries out in the photosynthesis process. And here's a secret: tree leaves are usually brighter on the top than the bottom. I had not noticed this until it was pointed out, and now I see it everywhere...

And, strolling through the park one day, in the very merry month of --June, sorry-- a remarkably colored bird landed in front of me: it had a sleek gray body, white tail, black head, and red crown. And then it flew off before I could ask its name. Does anyone know?

So trees & plants are more ingenious than I realized, not just ---forgive me here--- for the birds.
