Some British Columbian orca are facing food shortages - not only does there appear to be less food for the Northern resident orca of the Pacific Northwest, but they are travelling in much smaller groups and communicating less amongst themselves compared to what has typically been observed in previous years. These orca eat Chinook salmon almost exclusively and Chinook numbers are much lower this year than expected.
