Peter, the last shot with the Toronto skyline is one of my favorites of your many masterful BIF images. Cities have to be considered a part of the natural world at this point; after all, we have commandeered a lot of hectares for our steel, concrete and glass nests. I love the feeling of getting far enough away from obvious human engineering to think I'm "in the wilds", and I fight to protect the degree of "unspoiled wilderness" that still exists (at least given a narrow look at it), but it's also important to recognize that animals and plants have to find ways to coexist with the voracious appetites of human society, and in many cases they are surprisingly successful. (Just look at insects and rodents, not to mention bacteria.) Anyway, that's a long winded way to say that I like seeing free flying birds in a setting that is clearly connected to the urban landscape.
(I like the occasional shots of "rock doves" in the actual city canyons, too.)
