Long-staying Caspian Gull, Cromer beach
I spent an hour or so yesterday morning on Cromer beach, looking for unusual gulls. I had to walk east from the pier as far as the beach-huts and then walk back, to get beyond the roost – avoiding disturbance and ensuring that the sun was behind me. One of the first birds I came across was, what I thought, a good candidate for the long-staying 2cy (second calendar year) Caspian Gull. It immediately stood out because of it’s overall structure, white head and dark-centred tertials. I spent some time watching it before moving on to look more closely at the other fifty or so gulls along the shoreline. Not finding the hoped-for Polish colour-ringed bird, I returned to the original bird. Before long it was disturbed and briefly took flight, allowing reasonable views of the pale under-wing and tail pattern.
Mark Golley, well-known Cley larid enthusiast, had this to say about it:
Your lovely shots are indeed of a rather fine 2cy Caspian, what a handsome bird… flight shot picks up a number of classic in-flight cachinnans features ~ you’re absolutely right to pick out the underwing/axillaries; the whiteness is almost diagnostic of the species (and) are spot on for 2cy cachinnans (YLG will still show a variable degree of darkness across the same areas). The extensive smoky grey-brown shawl is shown nicely, as are the smudged flanks. The tail pattern is shown nicely too, the lovely shape of a Caspian whilst the upperwing pattern, the contrast-y look given by the greys, brown and dark blackish trailing edge to the secondaries all add up to classic Caspian Gull.
The colour-ringed bird was reported around the pier a couple of hours later!
A late afternoon walk in Felbrigg provided most of the same stuff as recently, with a couple of surprises. The first bird I saw on entering through the back gate was the juvenile Cuckoo – present for it’s seventh day now. No sign of any sandpipers, Green or Common, but the two family parties of Little Owl were calling furiously to each other – one near the ‘hollow oak’ (three birds) and the other in the south-east corner of the lake (two birds). The female Mandarin was on the lake whilst, what I assumed was probably Sunday’s female Marsh Harrier, flew over-head at 17.00. Through my binoculars I thought I could see some odd coloration, but it was mainly against the light and I had to wait to look at the photos to confirm that it was indeed wearing a red wing-tag on it’s right wing! So, definitely a different bird and possibly one from a ringing scheme in Kent – I’m in the process of checking.
