Another nice morning. I'm not a bird watcher who goes out with binoculars to spot them, but I do like to watch them. They say they are the last of the dinosaurs. I think that's kind of neat, although it's sort of hard to think of a hummingbird as a dinosaur.
They are super efficient. They don't require as much water as mammals because they don't excrete waste as liquid urea, but as solid uric acid. The hummingbirds are an exception. I've seen them squirt as they fly away from the feeder and there are lots of drops of their poop on my patio.
Birds have an extra air sac beyond their lungs, so air blows through the lung on both inhale and exhale. That's why some of them can fly over the Himalayas. And their brains are wired more efficiently too. That's why birds like crows and parrots are so smart.
I used to wonder why the bird bath went down so fast. Then I noticed that when they bathe they splash it all over, especially the larger birds. They really get into it.
One of my favorites is the California Towhee, a brown bird with an orange butt. They will get within several feet of me if I sit still while they hop around looking for whatever they eat, making little peep sounds. Here's a drawing I got off the web. They hop, but they can also run like little road runners.
I rolled my scope out last night to take a peek at Saturn. Its rings are edge on right now so it looks like a ball with a line through it. I hardly use my scopes. I should sell them, but maybe I'll get interested in astronomy again some day. Here they are.
