On the trail I wonder whether anyone knows what this pattern is that I found on my north-facing window sills earlier this year? It looks like some kind of footprint and seems to come in two sizes. A few months on, it's still there...Andrew Rolph, Horley, Surrey, UK

Why is calling "cooee!" a good way to draw attention to yourself?

In Australia, the loud, shrill call of "Cooee!" is often used over long distances in rural and mountainous areas to draw attention to oneself. What is it about this word that makes it more audible over distance and is there a word more suited to drawing attention to myself should I be lost in the outback?

Plenty of speculation on this one so we're keeping the file open for a while. Thanks to those who point out that "Gooweet" was devised by Australian Aborigines for gaining long-distance attention, while a few hundred years back "hoooooha" was popular in Sri Lanka - Ed

Ice circles

In February, the tarmac roof of my office building in Hilversum was covered in hoar-frost. When I went for a walk up there, I noticed some circle-shaped patches. An outer annulus had a darker colour than the surrounding hoar-frost, an inner disk was ice-free, and in the middle of the larger patches sat a millimetre-sized ice grain, resembling a small hail stone.There were some hundred of these patches, some merged, or with multiple ice-free inner disks. The day had started out freezing, but when I noticed the pattern, it was around 10 Â° Celsius. All day, the sky had been sunny, but the tarmac was in the shadow of a building.What caused these patches?Bruno van Wayenburg, Leiden, Netherlands
