i spent 90 minutes there. I don't go by the river, so I can't comment on water fowl.
notables noticed at the park:
pileated woodpeckers x 2. Ah...its been a long time coming. Spotted the male hammering away at some trees on the hill near the bridge. A northern flicker came and fought with it and chased it away. It eventually landed 2 feet off the ground (!!!) and gave a group of spectators some great views. 5 minutes later, i heard the hammering and spotted the female near the river. Its funny - the male took off north west towards Royal York. The female took off south east.
northern flicker x 2. They were really noisy. looks like they're nesting off the trail.
red-bellied woodpecker x 2. They're also building a nest right along the walking path. Fun to watch. They're up high, so not photo worthy but nice to watch.
Gold-crowned kinglets x lots. They were really active in the shrubs between the sloppy walking path and the paved by-the-river path. Can't tell you how many there were, but they would be flying in groups of 2-4 and flitting around.
of course, lots of other woodpeckers and other fun things.
