We were able to get within about 100’ or so before dad decided we were too close and got a little concerned. So he dove and came up behind us and proceeded to put on his ‘look at me, I’m hurt’ display to draw us away from his mate and the two chicks.
It was also about this time that the missus discovered she had a stowaway in her kayak. A small (24” or so) garter snake had, we assume, been quietly chasing insects in the kayak when we came along and disturbed his hunt with an unexpected boat ride. Needless to say the return trip was much quicker than the leisurely paddle out into the middle of the lake. And the snake wasn't too happy either.
I think a very thorough inspection will be in order before our next trip.
But all’s well that ends well. We saw the loons and got some photos, the snake has a new story to tell the snakettes, we had a nice paddle – at least the first half, and once again we got to realize just how fortunate we are to live where we do.
