Variable Oystercatcher - Kaikoura, South Island, New Zealand
Magellanic Oystercatcher - Falkland Islands
Blackish Oystercatcher was also photographed the same day (Boxing Day 2007) but being pursued by a Falkland's Skua, it looks rather like a blurred stick being thrown into the sea.
Sooty Oystercatcher - Cape Leeuwin, Western Australia
Black Oystercatcher - Cape of Good Hope, South Africa
I'm not going to use the 'O' word in case I upset both myself and others, but I just don't know how I get so much information mixed up (maybe that's why my World Bird List stands at 12,800?) The pictures of Chesil beach, below, have no connection whatsoever with Spring Tides, or any other tides for that matter. The erosion and movement of the beach was caused by the storm of 9th February 2009, as the histogram above adequately highlights. My apologies to all and sundry.
