The birds are restless, with 250 species of the land's 660 known breeds migrating over, around and through town, starting now. Hardest to identify are the fall warblers, all nearly the same size and all losing their summer plumage now, with the black-throated blue as dun-colored as the orange-crowned warbler. Really, it's easier to leave the city parks and the small birds behind and go out on the water for a last Indian summer look at the birds.

Canoeing allows for intimate viewing, with the local rivers still warm and tame enough for looking up instead of ahead for white water. You can see owls, though rarely at midday. A family of barred owls gave us a good look as they flew from bough to bough above Virginia's wooded upper Rappahannock. A bonus was a wild turkey on the road back from the take-out near Sperryville.

A single barred owl, prey in talons, was hounded by crows above Goose Creek, also in Virginia just outside Middleburg. This little bywater fairly teems with songbirds, but they're quieter now because they're not defending territory. And there are lots of drab juveniles that make identification more difficult.

Patuxent River Park in Maryland offers a good float and some easier birding. You'll see osprey nests when putting in at Jugs Head Bay. Use the ramp below the park's official entrance and, with luck, you may see one of these elegant white birds flashing its black-tipped finger feathers. Then head out of the open water and paddle toward the marshy Merkle Tract. It's quiet now that the redwing blackbirds are no longer harassing paddlers. There are egrets and little green herons and, at dusk, you might still see a night heron. If you canoe quietly, you're apt to come upon great blue heron at a bend in the river. The wood ducks here have followed us for bits of sandwich.

In the eerie Pocomoke Cypress Swamp, near Cambridge, Maryland, the gnarled red knees of these fabulous trees poke up from the tea-colored water. Here, with luck, you may glimpse a glossy ibis. A naturalist friend, calling it a fluke, saw a flock of bobolinks there last week. There were woodies, too. Prothonotary warblers, which in summer put on a long display not three feet from the bow, were shy, he said. But even without a single sighting, this is a wonderland. The swamp, northernmost of its kind in the United States, lies outside Cambridge. There are put-ins off many back roads. Watch for leeches and no-trespassing signs.

In the same vicinity is the Blackwater Preserve, which you can canoe with permission from authorities, but not during hunting season. Last October, though, it was windy and cold when we made the trip up for the Canada geese. A naturalist traveling with our party turned chilly when someone called the huge buff-and-brown birds Canadian Honkers, a field mark of the beginning birder.

Honkers they were, though. We heard them, sounding like a brass band as big as Kansas, long before we saw them up close, although V-shaped formations were landing in a blitz. On the ground, the view of thousands and thousands of migrating geese is awesome.

On the way to Blackwater, there are herds of cattle egrets foraging in the cornrows. There are also snowy egrets and bald eagles, which you can view at your eye level from a tower in the Blackwater preserve.

The raptors are also moving along with the shorebirds at Chincoteaque and Assateague. The backwaters behind the dunes are navigable and there are plenty of sightings to keep binoculars busy. For the fall season finale, the whistling swans take to the flyway near here. Last year, so many traveled the coast over Cambridge and on to Bombay Hook that visitors driving up from the Carolinas mistook the flocks for a freak snowstorm.
