Carrion Crow

Thanks everyone for your suggestions. It was in Hyde Park, London. I think you all are right. Additionally I noticed in the pictures that ravens have bigger beaks. So I am gonna go with Carrion Crow. Thanks.

the common raven is enormous,in a park like Stian says ,it's a carrion crow and like Karen says it as not the big shaggy appearence of a Raven

i think is a corvus corone,very common in my area i se then every days:-)

The common raven and the carrion crow are very similar, hard to say.. Your picture looks like it is from a park? I would say it's a carrion crow if this is in the city.

I think these are carrion crows http://en.wikipedia.org/wiki/Carrion_cro...
They lack the shaggy appearance of a raven.

Thanks. I thought they might be ravens, but I decided to keep the name open for suggestions. I will ID them after I get a good name suggestion, or I find out the species name myself.

looks like Ravens? great pic!
