Migration is now in full swing.  Total waterfowl around 235,000.  This is
about double the average 131,000 for this week in March.   Total shorebirds
around 1300, average for this week is about 2600.  All units are open and
ice free.  Very good observation around the tour loop of tundra swans and
waterfowl.  Oh, and gulls!

 March high counts of American Wigeon, redhead, ruddy duck, bufflehead,
great blue heron, and Bonaparte's gull.  First spring observations of
Bonaparte's gull, tree swallow, red-shafted flicker, yellow-headed
blackbird, savannah sparrow, American avocet, Baird's sandpiper, Caspian
Tern, golden eagle, dowitcher, western and Clark's grebes.

About 30% of all birds tallied were observed from units around the tour
