Good point. I guess it is a bit like the catapults on the aircraft
carriers, or submarine launched missiles.
It would be interesting to see high speed movie footage of a quail taking to flight - how far does it jump up before its wings take over?

Most ground living flying birds jump up as a start to each flight. Many ducks do too. Some perching birds do also. Sure that is not very dramatic and that is up to you whether you call that "a noticeable capacity". Many years ago when I kept finches and quails I confined the father King Quail to a wooden cage when he was being aggressive to new chicks. That proved his doom when my father came around the corner and looked at him closely and he got frightened and jumped up and either broke his neck or smashed his head on the wooden roof of the cage and died in a shaking mess almost instantly. That tells me that King Quails are capable of very powerful jumps. I suspect that is a common thing of things like quail, and consistent with the way they fly off so quickly in the wild. After that I padded the roof of thecage.

There were some week old ducklings in the cascadesection. One was at the bottom, while its siblings were in the uppersection. From a standing start, the duckling leapt up the 30 cm to the next level. Leaping up is not an activity you see often from birds. Flying yes. Walking yes. Running yes. Jumping down yes. Leaping up? I've seen footage of penguins "jumping" out of the water onto the ice (from a swimming start), and I've seen ducks hopping out of the water, but I've never seen a bird jump up three times its body length. I doubt there would be many people who could jump onto a ledge abovetheir body height and land on their feet from a standing start withoutusing their hands. (The people who jump up more than their height have a run up and they don't land on their feet. People who jump three times their height are using a long pole to lever themselves up). Are there any birds that have a noticeable capacity to jump up? Regards, Laurie.
