I read the piece on temporal synchrony. I tried without success to find any clue in it as to what it was all about. It's good that our universities support these really really clever people in their endeavours. Where would we be without them.

Like horses, I think they have a sort of elastic material in the joints to the hooves (must be similar to what fleas have too(, for horses in the main acts a shock absorber, but can be 'coiled/retracted' for jumping. Cats I think use leg muscles and loose bones on their jumping and landing so different techniques.
That's great, well done! Do you see any greenfinches? They used to be common but then were badly affected by a disease that's carried by pigeons and passed to the finches through drinking water and feeding stations. It's a horrible disease and has wiped out the greenfinches in many places.StoneRoad wrote: ↑13 Jun 2019, 09:46 This year, for example, two breeding pairs of greater spotted woodpeckers, several members of the tit family and at least two pairs of goldfinches, blackbirds, robins, wrens and chaffinches make up most of the rest. This year I seem to have acquired some house sparrows ...
We used to have greenfinches, but not for some years. I take care to clean my feeders and the areas concerned and I move the sites quite often as well.Tizer wrote: ↑14 Jun 2019, 10:55That's great, well done! Do you see any greenfinches?
