For Sunday's afternoon tours, we traveled to Haro Strait where we met with the transients again. We also met up with Tucker, a local whale researcher of the canine variety. Tucker spends his time sniffing for whale feces, which is studied by human whale researchers to indicate stress levels, state of reproductive hormones, exposure to toxins and diet. The two male whales were active this afternoon and it was a thrill to have such an intimate encounter. We even saw one of the whales swimming upside down at the surface! Our afternoon trip ended with a great tour of the near shore waters of Chatham Island and Great Chain Island.
