Ravens are fucking *huge*. you will know if you see one because you will think "who crossbred a crow with an aeroplane?". Rooks have thinner beaks than crows and come in groups of about a billion. You are not going to see a raven in London outside of the Tower. We have a bunch of jays near me - I spotted one on the way to the gym, hopping around in the grass about 10ft away, eyeballing something very hard. They have beautiful blue eyes!

One of my fondest robin memories is watching one bully several pigeons away from the benches in the Hyde Park rose garden at Marble Arch. Also, there's at least two species of woodpeckers in Alexandra Palace's park - strongly recommend coming along at some point as it seems to be a big spot with the bird-watchers. There's loads of waterbirds in the adjacent reservoir, too.
