Gray days

Yesterday was a gray but pretty day. Everything was gray. The sky was gray. The trees were frosty gray. It looked like something out of a fairytale. Today it's just gray. Everything is still. No movement. I finally saw some birds sitting on the telephone wires. I enjoy seeing an entire line of them sitting there and always wonder why? Here's what I read:

"It fits their claws easily, and they are high enough to see things- with no branches for predators to climb up. Hawk populations increase where there are telephone poles to perch on."
