A female Whinchat was perched on railings near the Diana fountain. Paul Turner found it and got a good clear picture.
These summer visitors are seldom seen in city centres, though she is not the first to be seen in the park.
A Reed Warbler was singing in the reed bed at the east end of the Serpentine -- the fixed reed bed, not the ones on rafts. So was one in the reed bed near the Diana fountain. It isn't clear how many male Reed Warblers there are. There might be as many as four males, since one has already been heard singing in a reed bed in Kensington Gardens. Or they might just be moving around. There is at least one female too. Here is the male from the reeds near the Diana fountain.
The first young Starlings have come out of their nests. This one -- one of several -- was in a tree at the south end of the Parade Ground.
The bereaved male Mute Swan from the Long Water was on the Serpentine, cruising around in his usual swaggering style and bearing down on some unattached young females. It is hard to tell whether he was trying to court them or chase them away, but they retreated anyway.
A Grey Heron was sitting on the post next to the one with the Moorhens' nest, looking away but occasionally glancing over his shoulder for the chance of a raid.
The Egyptians that I photographed on Saturday with six young now seem to have nine, which is far more than usual and raises the possibility that they have adopted some. They were at the Bluebird boat hire platform, but two of their youngsters had wandered off to the far side of the lake and were calling pitifully. One of them is very blond. When I came past the platform later the young ones had found their parents and all was well for the time being.
The Egyptians who bred on the Round Pond in midwinter are now nesting again, in the same tree as before. Their father was looking after the half-grown young, of which five survive.
The female Grey Wagtail was hunting insects in her favourite place near the Lido.
On a blustery, stormy day the Little Owls were staying inside their tree, and no one saw them. So here is a fine picture of the pair taken on 27 April by Michael Morgan.
