Egyptian Geese: fledglings

It has been so difficult to choose what to blip today: I took pictures of dandelion clocks, a bee visiting a daisy, very new cootlings on Clapham Common (they weren't there on Thursday...), and lots of interesting gosling photos (including one flapping its little wings: awfully cute, and definitely my favourite picture...).
BUT, the big news is that they're now (almost) fledglings; they have started to produce contour feathers and are no longer just downy. It is still a very patchy thing, but I thought it needed blipping. It is harder to see at this size, but they've feathers on their fronts and sides, but also one or two at the top of their "wings".
This is (almost) the whole family; the father was chasing away the riffraff pigeons.

I love the way that the elegant goslings enter the water: as adults they slide gracefully in, often using their wings to ensure that it is a smooth process, but as goslings they seem basically to plummet or fall in once they've decided that the water is the place to be. If they're on a beach or slope it is easier, and they can just walk in, but if there is any edge or lip involved, they do seem pretty much to reach the edge and just switch off and hope for the best... Most amusing.
I also like seeing them leave the water, because the goslings now reckon they're pretty much big birds, so get out of the water and flap their wing[let]s to shake the water off their, um, plumage/wing feather.

They seem to be providing me with endless intrigue and enjoyment. Many other people seem to be following their progress too; I've chatted with quite a few different followers (who've said, amongst other things, "when did the ninth one disappear; do you know what happened; did someone take it?", "they're usually over there by the traffic lights, not on this side of the pond by the grass..." &c.).

p.s. one gosling/fledgling was obviously camera shy...
