It's not uncommon at all to see a deer along the river banks, as one traverses the Greenbelt. And any regular cyclist will attest that occasionally you find yourself slowly zig-zagging among the abundant Canada geese. (For me it invokes the haunting final scene in the Hitchcock classic, The Birds, when Rod Taylor drives his Aston-Martin into the sunset, as millions of birds slowly clear a path for him.)
But a few wildlife viewing opportunities have been a little less common.
I've ridden the Greenbelt out to Eagle Road a couple times this spring. And on the most recent trip, I saw several swans taking rest in the dredge ponds. Beautiful!
And a bit farther downstream, it's nesting time for the cormorants... hundreds of 'em perched in the trees.
Even more uncommon in these parts is a giraffe viewing. Which should convince even the most ardent global warming skeptic. There was a time when giraffes were rarely spotted outside of Africa. But Africa's too warm for 'em nowadays.
