A couple of years ago, I was at the London Wetland Centre when I noticed some lapwings behaving in an unusual manner. After watching for a short while, I realised that they were dive-bombing one of the innumberable grey herons that inhabit the LWC in much the same way that crows will mob birds of prey such as buzzards. The heron in question, instead of standing immobile as per usual, was moving resolutely through the terrain. I presume that the lapwings had a nest in the area and the heron was looking for a cheap meal. The process went on for quite a well and resulted in a victory for the lapwings; the heron feeling distinctly uncomfortable under the barrage of aerial attacks. Here's a few photos that show what went on.
