This week’s photo has been stolen from Marcus Stensmyr’s Facebook page. Marcus is in the Deparment of Evolutionary Neuroethology in Jena, and works on olfaction in Drosophila (and land crabs). And the great thing is, I have no idea what the answer is, unless Marcus tells me!
Looks like a Black-throated thrush (Turdus atrogularis).
Two votes for T. atrogularis, probably a first year male:

I’ve been struggling for a while to come up with an example of a “nonadaptive” radiation (that is, one not driven by ecological specialization). Turdus might be a good candidate.
Neil and Ben you are both wrong, that is very obviously a bird.
