Following on from my “autumn” theme, maybe we can have some off-beat pictures showing wind direction.
usually take off and land into wind and rest with their bodies aligned) with
wind to keep feathers smoothed (although heads are turned when sleeping).
Some small birds don’t seem quite so fussed about wind direction.
birds such as Kestrels always hover into wind.
I would use that information when taking off from one of Amsterdam’s runways. The resident Kestrel (in the absence of a windsock) gave a very useful indication of crosswind (if any).
So, where/what was the origin of this smoke cloud?
