SAN JUAN ISLANDS, Wash. -- The absence of southern resident orcas in inland waters this year is stalling the science researchers say help shape policy, but it also shows what they already know: There's not enough food -- and their poop proves it.
Eba, a rescue dog owned by researcher Deborah Giles, has a nose for orca scat. She proved it the first weekend in July when the southern residents came inland for two days before jetting back out to the ocean.
