[obol] Tundra Swan- Departure Dates

[Henry Horvat]

Does anyone know the average departure dates for Tundra Swan?

Birds of Oregon, a General Reference is not very clear about departure
dates.

It has been quite awhile since the large numbers of Tundra Swans have
left

the mining ponds in Scappoose Bottoms.

Yet on Wednesday 4/30, I saw a single Tundra Swan flying north over

Freeman Road. Is this sighting that unusual?
