I think your choice of binocular is good, but I would take a look at the 8x42. I have found that the 10X is just too big to hold steady, especially those quick glances with one hand. I've had the 8X42's for a few years now and I can't say enough good things about them. They are plenty powerfull, lighter, and much easier to hold steady, which is critical in not only identifing animals quickly, but judging them as well.
