At Far Pasture there's still no sign of any Grasshopper Warblers, but has had a recent influx of Garden Warblers with at least three pairs there this morning, probably more. No sign of the Mandarin which was still there on Saturday for its third day. Clouds of midges formed in the treetops around the car park.

Not a particularly good day with the camera, the garden warblers joined the blackcaps and whitethroat in this year's most uncooperative birds competition and record shots were iffy to say the least.

I'm always fascinated by the way things in the natural world find a way to interact with each other to gain an advantage. Watching a repeat of The Nature of Britain yesterday threw up such a case, in how ants inadvertently aid the dispersal of gorse seeds.
The seeds themselves are of no interest to the ants but they come with a blob of a fatty yellow substance attached which the ants find to be a bit of a delicacy. Foraging ants stumble upon one of these seeds after they have exploded from the pods but the foragers tend to be the older members of the colony and their jaws are no longer sharp enough to cut the blob of fat from the seed, so instead they use it as a handle to carry fat and seed back to the nest, where a younger worker will snip off the yellow substance.
