Yeah, I saw a lot of that yesterday as well. Seems like they're flapping, hopping, and seeing how the wings help with that. I was wondering what would happen if one jumped to that perch and then fell off?? A day with some good wind would also give them some confidence. As of this moment ( 5/29 13:04:20 in your video), one actually separated about from that limb extension by about 8-10 inches. Getting close!!
