The male Tawny Owl is back in his usual place, the broken trunk of the hollow tree where the pair nest. The nest is farther down the same hole. It is a fine place for an owl, since there seem to be several places to stand and he can go right up to the edge or huddle down out of the cold wind, and there is enough room for his mate to stand beside him when she takes a moment off from the eggs or the young owlets.
The male owl is gingery brown and rather round-looking. His mate is paler and taller, with high eyebrows that define the shape of the top of her head. She is also greyer than her mate, though it does not seem so from the fine photograph below by Paul Sawford, as it was taken in bright sunlight. It is from 30 March this year, when the family was camped out near the Albert Memorial.
The Great Crested Grebes near the bridge are giving their family a varied diet. This seems to be some kind of freshwater worm.
But I have no idea what this irregular black lump might be.
However, the young birds are thriving, and I saw one of them already charging across the water trying to fly.
