Day 13.262: Lunchtime sighting

I don't often have any interesting bird sightings on work days, but today as I was arriving back at the office after lunch, I saw this fly by and land in a bare tree. I stopped to take a few photos:

It seems to be an immature accipiter - possibly a northern goshawk (the white line above its eye suggests this - although they are rarer than their cousins Cooper's hawk and sharp-shinned hawk both of which look quite similar in their immature plumage). A nice sight in any case.
