First reported by others 3 days ago, small tern much like whiskered but with strong headphone pattern on head. White underneath, and a mix of grey and black on upper wings. Non-breeding. Hawking low over the water of the back pond for the entire period of observation (>1.5hours) without rest. This involved feeding up and down in a wave like pattern low over the water from right to left before flying high back to the right, then repeating the sequence. Visible from the road near wetland offices, well lit by the afternoon sun. Pursued by a (much larger) silver gull on a number of occasions, but unperturbed by the whistling kite unlike the gulls. Photos to come
