Here in the States, we have an idiom: "Pigeonholed,"
which means "typecast," or "stereotyped." In this
case, I am calling this image Pigeon Hold because it's
a bit of a pun, and because each pigeon in the picture
seems to have a hold on the roof in his or her own
little space. Lesson to building designers: don't make
the pyramid shaped roof out of glass, or if you do,
don't give pigeons something to hold! If you do, you'll
have a mess, like this!
