on a naval air base we have a breeding pair of buzzards in a wood near one of our gates, About this time of year they'll have a youngster they lost last years, It flew into the razor wire severing a wing my daughter came out to put it to sleep, Such a fine bird too. They do this kind of tumbling act now & then, sort of re establishing the bond they get right up high & you'd think they were going to hit the ground but they soar back up & repeat it, Real nice to watch on a quiet day.
