Bear River Refuge Waterbird Survey

Bear River Migratory Bird Refuge
Waterbird/Raptor Survey
Box Elder County
4/23/04

Total number of ducks is about 20,000 off from the long-term average at
about 40,000.  I think most of them are around, they're just out on Willard
Spur.  Total number of shorebirds of about 24,000 is close to the long-term
average of 17,000 for this time of year.  Shorebird migration appears to be
about a week ahead of schedule as far as the avocets and stilts.  Highest
use of the Refuge by all birds is in Unit 6 out on the spur.  New birds
this week include Forster's Tern, Prairie Falcon, Wilson's Phalarope, Sora
and a Eurasian Wigeon spotted by Mark Stackhouse in Unit 1.  That's the
most Willets I've every seen at a total of 28.
