All day a Whinchat sat on the same piece of dock on the Wader Scrape, occasionally turning around or sallying forth after an insect, but always returning to the same perch. On the Causeway a Spotted Flycatcher paused briefly on the fence, dropping down, Robin-like, to catch an ant in the grass, before returning to the fence to eat it. It was a flying ant and I think the Whinchat was hunting the same prey. Black-headed Gulls were also hunting the flying ants, and so were squadrons of Migrant Hawkers. PS.
