The 60,000 daffodils planted by children along the edge of the Serpentine are beginning to flower.
A pair of Robins near the bridge, temporarily united by the mating season but still wary of each other, were sitting a safe distance apart, carefully not looking at each other as that might be seen as a challenge.
The Redwings had apparently gone from the Parade Ground, but there was a pair of Mistle Thrushes, again not too close to each other. While one foraged on the ground, superbly camouflaged against the bare earth and dead leaves ...

The Great Crested Grebes on either side of the bridge were also feeling the call of spring, which they expressed by restarting the territorial dispute which they had enjoyed so much last year. Here is one in the typical threat posture, with head held low and ready to shoot forward in a ramming run if the other bird comes too far forward.
Their territorial call sounds like 'Go back, go back', which is exactly the message they are conveying.
The male Tawny Owl was inside the nest tree after a rainy night, but when the sun came out in mid-afternoon he emerged for his daily photo opportunity.
