Normally from my apartment I can see the typical array of pigeons that pollute this city, and even a few seagulls as I’m near the East River. Recently, however, I’ve noticed a murder of crows—yeah, that’s right! Murder!—hanging about my neighboring rooftop. To add to this equation, some hawks have also been buzzing my windows. Now I’m not saying that these birds are starting to organize and are planning humanity’s imminent destruction, but it seems pretty obvious to me.
