A brisk west wind was moving the floating baskets of plants at the Serpentine island, allowing views of places that are usually hidden, and this revealed a curious sight. There is one Great Crested Grebes' nest on the northeast corner of the island. But now I could see that there is another one just 20 ft to the west of it, with a rather bored-looking bird on it ...
... and another one 20 ft to the east, around the corner of the island.
It is not at all usual for grebes to nest so close together: they have a comfort zone of at least 50 yards, and even at that spacing have frequent territorial disputes. Also, you would think that there are plenty of other places behind these baskets where a grebe could nest (unless these are occupied too, which would be wonderful but most unlikely).
A juvenile Lesser Black-Backed Gull was eating a pigeon on the shore of the Serpentine.
We already have two adult Lesser Black-Backs that kill and eat pigeons. It didn't look as if this pigeon had been taken by one of those, as the gulls eat them down to the bone, and there was still plenty of meat on this one. It seems that the hunting behaviour is spreading; gulls are intelligent birds and are known to copy another bird's successful feeding strategy. If so, the park pigeons are going to have a tough time in a few years. They are already predated by the local Sparrowhawks and Peregrines but there are only a few of these, while there are lots of big gulls, especially in winter.
One of the small Moorhen chicks on the Italian Garden pond was behaving oddly. There is a line of water lily flowers, and it climbed on to the end one and walked from flower to flower right along the line.
To judge by this picture, it found something to eat on the way. But I think it may have made this excursion simply out of curiosity. Moorhens love climbing on things, particularly difficult and challenging objects such as branches, wires and chains, and I am pretty certain that they do it for fun.
I wouldn't normally publish a picture of a grey squirrel, but sometimes you just have to.
