  • In the afternoon, one large eco-tour boat came through the reserve.

April 12

As the sun set, the wind shifted around to south-southeast after blowing about 10 knots  from a westerly direction most of the day. The snow line across the Strait is very low and the chill in the air continues. Although there was some sunshine today producing a high solar radiation reading of 1,000 watts/m2, there was also a lot of cloud. The barometer reached a high of 1020 hPa mid-day and then began to fall. The forecast is for southeast showers switching back to westerlies tomorrow afternoon.

Only one tour boat was observed in the Ecological Reserve today and although there were dozens of sports-fishing boats all around the reserve none were observed inside.

American Pipits have been spotted bobbing and flitting around Great Race and there is a photo below as evidence. Thanks go out to Rocky Point Bird Observatory for the identification confirmation.

Six Northern Elephant Seals came ashore at first light and spent the whole day sleeping in the garden. One was a tagged, with a pale green tag #5850. This same individual had two tags when I first saw it last fall, October 14.

The Canada Geese are in over-drive right now and uber-territorial. One pair tried again to take up residence in the entrance way to the de-salinator room which is just not going to work.

The Glaucous-winged Gulls are engaging in more definite pairing behaviours and also becoming more territorial. Many are nest building, pulling out chunks of grass turf for padding. Black Oystercatchers are looking broody too and I observed Black Oystercatchers eating limpets today.

 

There were no visitors today.
