A different nest at Ynys-hir has two chicks at a much earlier stage of development, with 'contour' feathers just appearing among their insulating down.
Watch one of them battling to eat a rabbit leg.
Chris Packham and Kate Humble explain how a buzzard chick has a digestive tract adapted to cope with awkward food.
The buzzard chick is looking a lot more like its parents now, with most of its grey down replaced by brown flight feathers.
The buzzard chick is developing and has now been observed feeding itself when the parents deliver dead prey. Recent kills have included a squirrel, a great tit and possibly a young meadow pipit.
Another change in behaviour was a brief period when both adults were together at the nest.
RSPB Ynys-hir in Mid Wales is the location for Springwatch 2011. Among the birds featuring on the webcams is a buzzard nest.
Two adults are taking care of the one chick, which is already walking around and stretching its wings. They quite often leave it alone on the nest for long periods. He or she will probably stay in the nest until July.
Snakes, moles and the young of other birds (mallard, moorhen) have all been served up to the growing infant.
Something else that the buzzard chick ate was, er, its own sibling, when they were less than two weeks old.
Springwatch pointed webcams at two tree-top buzzard nests. Read the diary and watch as the various chicks grow towards fledging.
