What do we do with this boring brown bird? We cannot even see the head!

We assess what we can see on the bird. The quiz bird has a long wing, with the primaries extending well beyond the tertials. That might rule out a few options, depending upon what species one has in the set of possible solutions. There also seems t be something of a black collar. Perhaps that is something; perhaps it is nothing but lighting and how the bird is holding those feathers. Then there are those white-tipped primary coverts. What is up with those? Well, those are very important.

What species is represented here?
