Thanx Carla for your additions to the discussion. Especially the thinking 
about carrying capacity. I think its why so many of (hopefully!) put up nesting 
and feeding stations in an effort to mitigate somewhat the artificial quality 
of the planet. I wonder then how much of our observations in our urban world 
have any scientific validity. I suppose it doesnt matter. I was visiting a 
friend in her office on the 24 floor of a building on Market street when the 
Perrigrines bombed by. Ok they live in the skyscrapers as do the redtails of 
Manhattan. Nevertheless, the thrill is, however non scientific, just as valid. Just 
as when the cooper hawks of Canyon Trail Park in el Cerrito are nesting and 
hunting through my back yard. When i step out of my back door and am literally 
face to face( 4 feet!!!) with one perched on a pedestal of the retaining wall in 
our back yard.We stare at each other. How much does a Cooper weigh?? It didnt 
matter as I felt as small as the finches it was taking....
