Across the street from our house, in the lights of the tennis court, is the nesting grounds for a flock* of ospreys. Every evening you can see them wheeling in the sky and hear them calling, impressive vocalizations of interest and power. Though they are a common bird here in central Florida, its always a bit amazing to see them (and the owls, and the occasional hawk) in my very urban neighborhood. They like to stay very high, but they are so distinguishable that you never have any trouble knowing what it is you're looking at. And if you have a young puppy or kitten in the neighborhood, you need to stick close to it!
Especially at this time of year, when they're visibility (and the noise level) suddenly skyrockets. I think it has just a little something to do with those smaller heads peeking out of the nest. I also suspect the fact that I walked in to the backyard last night in to a shower of soft, downy feathers from a songbird may be connected. But, we won't think too much about that reality of the natural world playing out in my neighborhood.
*There has got to be a better word to use when describing a large group of birds of prey. Flock just feels so...well, sissy. It's the word for the cardinals or the mockingbirds, not these creatures with powerful beaks and huge talons.
