The gathering of gulls at Swan Lake this time of year provides a good opportunity to practice identifying them.
Swan Lake
Tracking Wind
Temperatures remained quite cold, but winds diminished significantly by later this afternoon. It was interesting to see all the polished ice intermixed with thin patches of wind sculpted snow. As windy as it got here over the last couple of days, it was much stronger elsewhere.
From today’s weather synopsis:
THE WEATHER PATTERN THAT CAUSED FREQUENT WIND GUSTS OVER 50 MPH SATURDAY AND SUNDAY FROM JUNEAU TO SKAGWAY AND THE CENTRAL OUTER COAST IS GRADUALLY WEAKENING. THE HIGHEST MEASURED WIND GUST WAS 150 MPH /130 KNOTS/ AT SHEEP MOUNTAIN SOUTH OF JUNEAU AT 3540 FEET ELEVATION. HIGHEST WIND GUST AT SEA LEVEL WAS 103 MPH /90 KNOTS/ AT CAPE SPENCER IN CROSS SOUND.
Forecast is for relative calm tomorrow and winds picking back up later in the week s a low approaches the coast of British Columbia. Fortunately, temperatures are also forecast to rise.
Pictures from today were taken as I walked across Swan Lake near sunset – hence the shift towards blue and lack of brightness (though I could have neutralized these things in processing, I found the contrast on the snow made it easier to see the texture and shapes if I left it as it was).
I didn’t notice too much unusual in the way of birds today, but one thing did stand out – there were three Great Blue Herons flying south over Swan Lake as I started across it. Perhaps they had all been roosting in trees around the lake and were headed to the beach for low tide. There certainly wasn’t any open water for them to fish around the lake.
Return of the Sun
The forecast was for cloudy to mostly cloudy skies with a chance of snow. Instead it ended up partly cloudy with the sun only occasionally being partly obscured by a small cloud. After lunch I was thinking the kids and I would go for a walk around the park, but the sun was nicely warming … Read more
Rainy Day Birds
Rainfall was continuous today, though the intensity varied from moderate to heavy. All told, over an inch of it was recorded at the airport recording station. No doubt more fell in some of the wetter areas of town. Temperatures dropped slightly, falling into the upper 30s after spending the past several days in the 40s. … Read more
Snow Returns
After catching the free brown bag concert put on by the Jazz Festival the kids and I got caught in a little snow squall. We waited out the strongest of it at the Crescent Harbor shelter as the snow, mostly in the form of graupel, fell. The forecast had called for snow with no accumulation, but by the end of the day the snow on the ground was approaching an inch deep.
The ice at Swan Lake continues to retreat. There were three Ring-necked Ducks, quite a few Glaucous-winged Gulls, at least one Thayer’s Gull, as well as Mallards and scaups. Today’s mix of scaups was different than yesterday’s, with two male Greater Scaups hanging together while another group of 5 Lesser Scaup males dove repeatedly at the edge of the ice. After the Greater Scaups moved around the peninsula to where the Lesser Scaups were, it was interesting to be able to compare them more directly and see some differences.
I noticed a Common Ragwort (Senecio vulgaris) with flowers still present. It was under a pine tree at the town end of the Lincoln Street green belt. Presumably the cover provided by the pine kept the plant from being significantly damaged by the frost. It seems unlikely the flowers will be able to produce seed, but I guess as temperatures rise in the coming months it will be interesting to see.
Swan Lake Visit
The kids and I stopped by Swan Lake again today to see if the swans might be there. The weather was much more pleasant than yesterday, so we stayed a little longer, but did not see the swans. We did find three Ring-necked Ducks and around 10 Lesser Scaups hanging out in the open water near the peninsula. All but one of these birds seemed fairly wary of us (the exception was a scaup who swam up close to shore near where the kids were sitting on a bench) – but the relatively small area of open water kept them close enough for a decent chance at observing them.
Scaups can be difficult to identify, and I’ll probably write up a separate post on why I think these were Lesser Scaups. I mentioned earlier in the week the mystery of the Ring-necked Ducks, but I suppose it’s also fair to say the Lesser Scaups present a similar mystery. I guess in the case of the scaups it’s easy to imagine they are just blending in with the Greater Scaups in the channel while the lake is frozen – they’re usually far enough out that it would be difficult to identify them – but I don’t really know that this is the case.
After the winds of yesterday, the prevailing calm today was a nice change. There were periodic showers, but nothing too extreme. Temperatures were in the lower 40s for much of the day. This afternoon the dew point was up between 39F and 41F, only a couple of degrees cooler than the air temperature. As a consequence of this and the lack of wind, a ground fog/mist formed over the surface of Swan Lake where there was enough ice remaining to cool the still air above it below the dew point.
