Elusive Nature

I admit I'm not the most patient of photographers, but I'm completely convinced that Nature herself conspires to keep me from capturing a number of what would be really great images. 

Take for example the picture at the right.  This is a photo of an upper level window in our stairwell that faces due East.  I was downstairs and calmly browsing the web a few minutes ago, trying to keep quiet so that the wife, daughter, and visiting son could sleep in, when suddenly I heard "flutter, flutter, flutter"....."flutter, flutter flutter"...repeated over and over.  As I got up to see what was going on, I found what I think was a Mockingbird flying into the window, presumably fighting its own reflection.  In the growing morning light, snapping on the light didn't make any difference, so I thought, "okay, if you want your picture taken, I'll oblige by going to get my camera."  A quick trip downstairs, a quick trip upstairs, and I'm ready.  Evidently the bird was ready too because it never appeared again from the moment I got the camera turned on.   Fink.

I've had a similar problem all Fall and Winter trying to get a picture of a hawk.  They're everywhere on the prairie in winter, watching over the fields by day for the slightest mouse-like creep or squeak.  But every time I try stopping the car or getting close enough to grab a picture with even my long-range lens, off they go.  And I've got such a good blog planned around a hawk picture.  I'd hate to waste the writing on a picture of a stark, empty tree limb.

Why, oh why, can't Nature just cooperate?
