I’ve noticed a few of these little fungi, the Yellow Fieldcap, recently. I photographed this example yesterday.
A very striking species almost buttercup yellow and with a glossy coating. But this only lasts a short while and I went back and re-photographed it today and already nearly all the colour has gone.
At the lake this afternoon a Sparrowhawk shot low over my head, followed a few moments later by a second bird. They then proceeded to climb, dive, tumble and chase each other for some minutes.
If it had been spring I might have thought this was some form of display (other than the fact they appeared to be the same sex). Perhaps they were siblings and just enjoying the feeling of flying in the wild winds?
