We got word that a very large group of Bigg's (transient) Killer whales were hanging out in Rosario strait, so off we went! We have had rather large groupings and mixing of various matrilines in the area this spring. Exciting stuff for sure! In this particular grouping we had multiple matriarchs and their offspring partying it up! Lots of social behavior as they travelled along. It was very exciting to watch. We had the T11's, T65As, T65Bs, T93, T97, and a I think a few others though we mainly hung out with the T11's a mom and adult son pair.
