Autumn is when spiders

and weather conspire

to do neat stuff.

Schooling.

School buses are orange so you'll notice them and take care to avoid harming the youngsters as they exit the door helter-skelter. I almost always take a window seat on the plane, and one of my amusements is to see how long it takes to spot a school bus as we descend.

If you are a small fish in a brownwater pond, it's probably best not to be the colour of a school bus. It would be unfortunate if your progenitors had been selectively bred to be the colour of a school bus, and then a couple, specifically Mom & Dad, had been dumped into a brownwater pond.

Heron, grebe, osprey, kingfisher and so on.

A few of you may survive to keep this going.
