This is an unidentified bird from Laguna del Sonso en Colombia, 21. July 2008. The bird had the size of a Kingbird and the bill was dark and strong. It might be a common bird, but I have not managed to identify it yet. I was thinking about Hooded Tanager, but the colour of the legs and eye is wrong (it is also to high or this species). Any suggestions?
Richard Johnston suggests that this is Cinereous Becard, and I think he is right. I miscalculated the size though.
