Acres of wetland habitat in London? Indeed, and full of migratory and native birds, and pretty endangered things from all over the world.
If you like your choice of lakeside hides and spending a winter's morning twitching, hithee. I am not a bird expert by any means. I know the names of most, not all, and I am pretty useless at spotting birds in trees and reeds.
This is where experts with industrial grade telescopes come in handy as your new best friends, spotting and sharing the rare Bittern, or telling you that that grey blob in the tree above you and out of reach of your tiny weeny binos is in fact a Green Finch.
Extras aside, there are plenty of fancy fowl to delight you. Do get there as it opens and before all the small people and buggies arrive to spoil the silence, well, sort of silence, if you can block out the planes making their approach to Heathrow.
Ashamed I have never been there until now. Rather happy that I have.
