In fact, they say by tomorrow it'll be summer. Beautiful sunshine here, though the air's still cold. Non-stop bird action on the water: five cormorants out on the pilings, more than I've ever seen at once here, and a sixth swooping by! Cormorants like each other's company, and colonies can grow big, but this one seemed to get off to a slow start. So I'm thrilled. We're up to our nests in Canada geese, who have two flocks down here all summer, though only about half a dozen birds actually manage to nest. The others just swim around, and I've never known why they don't fly off somewhere else and try to find a nesting spot. I guess they travel in families, though, and they come back to where they were born. The two gadwalls who've staked a claim to this part of the river, waiting for the grass to grow -- they don't actually build nests, they just flatten some tall grass and hide in the middle of it -- are getting very aggressive, for gadwalls. They're a shy kind of duck, but these two swam right up to the single mallard who's been chasing them. The male did the territorial duck thing, sticking his head in the water and tossing water over his back a few times, then flapping his wings. The mallard didn't leave, but he didn't get agressive in response, either. I think he was impressed. Then everyone jumped upon pilings for a nap.
