I am new and was motivated by seeing an amazing bird in my garden this morning. Where I live is about a mile from two rivers (one is the THames) in a suburban area which is a haven for birds. lots of old trees and gardens. Apart from the parrot and woodpeckers and our local robin, this morning I saw a bright green plumed bird, with a red tufty head and long flatish beak which pointed upwards walking in circles in the garden trying to scoop up some worms. He or she had a couple of flashes of bright yellow on his back. Larger than a pigeon (quite a bit larger!) I can't find any similar birds on any web identifiers. Any ideas?
