The youngest elephant seal pup came back ashore, on the east side of the island. She is easy to identify from the scar below her right eye. She spent the evening and night on the southeast side of the house, where she spent several weeks in February and March once she weaned from her mother. Today she had moved around to haul out on the boat ramp and swim in the sheltered water by the jetty.

A new sub adult male elephant seal has joined the other elephant seals. He is a bit smaller than the other sub adult male that joined the last week.

Yesterday there were two visitors, Guy and Corey, in the college boat Second Nature. There were no other boats in the ecological reserve.

The fog signal sounded for an hour this morning, before the sky cleared. It hasn’t sounded for almost two months. The fog signal is (3) 60 s, which means three blasts sound and repeat every minute. The more detailed version is blast 2 s; sil. 3 s; blast 2 s; sil. 3 s; blast 2 s; sil. 48 s.
