With six years of phd work on theropod dinosaurs behind him, Darren Naish mostly spends long hours in the library, hunched over his laptop. But he gets out sometimes, and picks up litter and pursues exotic lizards across the British countryside, aiming all the while to publish his technical work on obscure Cretaceous dinosaurs. He also messes around with pterosaurs, swimming giraffes, British big cats and stuff like that. He has given up on the stupid idea of being a dedicated academic and ekes out a living as a technical consultant, editor and author. He can be contacted intermittently at eotyrannus (at) gmail dot com. For more biographical info go 
Yes, I thought that birds didn't eat millipedes on account of their toxicity. Most millipedes (including the little species we have here in Britain) secrete noxious liquid through glands on their sides, and substances such as chlorine, iodine and cyanide are involved. As is obvious from the photo here, these chemicals don't make millipedes immune to attack from birds. After checking the literature I see that toads and hedgehogs also don't seem deterred by millipede toxins. However, other predators probably are, and toads and hedgehogs are actually unusual in being able to eat to tolerate highly toxic prey.
The photo shows a bird dropping on the top of our compost bin and, no, I can't identify the dropping to species. The millipede seems to have been eaten whole. It's a White-legged snake millipede or Black millipede Tachypodoiulus niger: we have a pretty good little colony in our garden. They're very neat little animals.
Comments
While living in the Congo, I noticed that while most of the chickens we kept did not eat the millipedes, every now and then there would be a chicken that ate them more or less regularly.
Those were the giant millipedes.

Did anyone dare to eat such a chicken…? Do they manage to accumulate the poison?

wow, I never knew millipedes were so toxic, I thought they were the friendly 'cousins' to millipedes. I know a couple of people who keep millipedes as pets too :/

Dendrobatids not only eat 'em, but sequester some of the alkaloids in their own skin:

Red Ruffed Lemurs actively hunt millipedes - not for food but to protect their young. They chew them up and smear the result on their small young before leaving them parked on a branch - presumably rendering their babies bad tasting to predators like the fossa.

Saw a meerkat eat one on TV.

The one thing I'm sqeamish about is bird poo. I find it deeply ugly and queasy-making. I happily point out mammal crap to my girlfriend and am unphased by ice-cream tub squirrel corpse mash body farming pics.
But that millipede squit means I'll be checking Tet Zoo gingerly for a week. I am weak.

Oh well. You win some, you lose some. Not sure why I'm replying - you won't be reading :)

The bird appears to have voided the millipede before digesting it completely. Perhaps digestion was too unpleasant. No benefit to the victim, but might the bird have learned to avoid such nasties in the future? (Recalling the famous picture of a bluejay eating a monarch butterfly and almost immediately vomiting it up.)
