This is the Dusky Moorhen - Gallinula tenebrosa - a close relative of the common Moorhen, which is found all over the world. "Moor" in this case is an old term for a swamp - so this is a swamp hen - which is just about as accurate a name as you can find.
I'l just post some pictures of this bird - hopefully showing that while it may be Dusky, it's not without some charm.
Now its over to you - click on the link below and off you go! (It's been a long day, and I have just got back from a school Christmas event - hence the brevity of the post!)
