There are various colour-ringing schemes being carried out in different countries on Sanderling, the colour of the flag should give an indication as to which country the bird was ringed in. I could not find a blue flag mentioned and so have emailed to organiser, but it may be that this bird is one of those that was ringed at Sandy Point on Hayling Island a few years back.
The second species that I recorded was a Knot. A single bird had been reported earlier in the week and I had hoped it might still be around. This bird was feeding in the middle section of the sea defences, and again was very confiding, although it did take flight when a large dog came skidding along towards it. This bird was also a first winter with the contrast between the adult and juvenile feathers very evident. The juvenile feathers are the grey brownish ones with a dark subterminal band.
There were at least 11 Purple Sandpipers feeding in the central and western parts of the sea defences. Initially the were quite close in, but as the tide receded they mover further out. Photographing them was tricky as I was having to shoot into the sun most of the time, and it was not possible get really close to them as the ground was too slippery.
There was only one Rock Pipit present and this bird was picking amongst the cracks . This bird also appeared to be a first winter bird; this was based on the fact that the two outermost greater coverts appear to be more broadly fringed, buff coloured and longer. The juvenile feathers appear shorter and fringed whitish.
