A recent posting showed a few characteristics of fog: fog wave. However, fog offers a far richer variety of features than those I showed there. Here is one more: fog drops that have collected on a spider’s web.
Similar pictures offered on the web are almost always described as being dew drops on a spider’s web. This is patent nonsense. For dew to condense on an object, there must be a marked temperature difference between that object and the air. The thread of a spider’s web is much too narrow to sustain such a temperature difference. Dew does not form on a web.
However, as a collection net for fog drops drifting past, a spider’s web is superb. While large obstacles distort the movement of the air flowing past them so that the fog drops are merely carried around them, the threads of a spider’s web are so tiny that they intersect and collect the fog drops.

Lucy has a new gosling
Lucy was hatched at least a decade ago. She is the only local Canada Goose that is a recognizable individual.
Normally, when we wish to identify an individual animal, we have to mark it with something ranging from a metal band, to an ear tag, or a tracking collar. This is because one individual looks much the same as the next (an exception being the humpback whale which is easily identified as an individual by the markings on the underside of its flukes).
To our eyes, Canada Geese all look alike (with the males being slightly larger than females). Is the goose that visited today, the same one that visited yesterday, or last year? Who can tell?
However, Lucy is leucistic (thus, her name): some of the black feathers on her crown and nape lack pigment. She has been instantly recognizable as an individual since she was first spotted in 2012, already with a mate. Since then she has been seen a number of times along the West Arm, sometimes with chicks. This morning, she was seen again along with her mate and a new chick.
Canada Geese are monogamous and can live for a couple of dozen years. Lucy may have a few more broods.
