Orca Conservancy regrets to inform you that seven week old L120 of the endangered population of Southern Resident Killer Whales has been declared deceased.
Ken Balcomb of the Center for Whale Research said, “L86 was seen and photographed on Friday, Saturday, and Monday, all without L120.”

….Survivorship from near the time of birth to about 6 months of age was estimated to be about 60% through 1987 (estimated a few different ways, none of which were very precise, but all giving the same answer within a few percent).
Lactating females burn two-four times as many calories as other females. It’s hard to produce enough milk when food is hard to find, and it’s hard for a calf to survive when it does not get enough to eat.
Hood Canal used to be an important feeding area for SRKWs, but they lost interest in it while restoration was in progress. Fish runs are much stronger there now than they were 30 years ago but SRKWs haven’t rediscovered it.
In about 15 years, SRKWs should see benefits from the Elwha Dam removal. We hope we’ll still have enough of them left then that it will matter. We need to be doing a lot of additional restoration work to get population growth back in the 3%/yr neighborhood that we know is feasible.
