Then suddenly we noticed that the air above the river was full of house martins, swallows and possibly sand martins (the two species of martin can be difficult to tell apart when they're speeding past in low light!). It was amazing to be caught up in the middle of all their activity as they zoomed over our heads in their circling round. I've seen loads of swallows andmartins this year, I'm wondering whether they've had a particularly good year or whether I've just been lucky with my sightings? What about swallows and martins in your area (if you're in northern Europe!).
There were also a lot of pied wagtails and goldfinches running and flying around and seeming also to be flocking together (though they're not species that I would normally see together).
Then we walked onto the beach, which had a wonderful autumnal feel to it, though it was warmer here than it was by the river. There were curlews and oystercatchers wandering around and a few mute swans too. A skein of geese flew overhead.
