I returned to South Norwood lake last week to see how the parakeets were doing that we saw mating a few weeks ago. I hung around their nest hole for a while with no sign of them, but then the male appeared and perched near the hole, before having a look inside. Then the female popped her head out for a look, before they flew off together.
I met a bloke who feeds the birds there every day (the ducks spotted him a long way off and ran out to him), and he was saying that parakeets roost near his house.
I also got a nice close view of a singing chaffinch, also a couple of wrens, a song thrush, a few goldfinches and I heard a nuthatch singing further off. All the shovelers seem to have left, but there is a pair of great crested grebes, plenty of tufted ducks, and several young cormorants, as well as the usual coots, mallards, moorhens, blackbirds, robins, pigeons.
