They have been nesting locally this year. They have discovered our nut feeders above our kitchen window and feed on them throughout the day.
We love seeing them and glad they have chosen Borough to make their home.
They seem to be everywhere in London. A few years ago, a huge group landed in the school playing field in New Cross and mobbed the cherry plum tree. Every single bit of fruit went in about 15 minutes. They are very noisy, and they are a nuisance because they scare off all the native birds. There's an estimated 6000 in the south of England - or so I read somewhere.
Humans are repulsive. We introduced rabbits then came up with myxomatosis, we introduced rats then convince ourselves they're dirty, now we turn our rage on parakeets. What a crappy species humans are.
