For clarification:

1. Hazing of terns on Rice Island was halted this year by
court injuction, because the Corps of Engineers and NMFS
could not show a relationship between tern predation and
reduction of WILD salmon stocks.

2. The birds were deliberately relocated to Sand Island by
a combination of clearing to create habitat and attracting
birds with decoys and tern calls. This benefits the terns
by putting them closer to ocean fish, increasing and
diversifying their foraging potential, especially for high
energy species like Herring.

3. Efforts to create nesting sites elsewhere in Washington
(eg. Grays Harbor) were halted because nobody seems to want
the terns in their backyard.

are up to is found at http://www.realtimeresearch.org
