Café Ursula is popular also among sparrows.

Yesterday several avian customers queued on a canopy cable waiting to be served. Some were happy with crumbs, but four of them wanted something more substantial. At a neighbouring table the humans had left a four square inch piece of open sandwich with shrimps, a piece of egg, and lettuce. Within a couple minutes most of it was gone. When a waitress interrupted the sparrows' meal to clear the table, only the lettuce remained.

And I was told at school that sparrows eat grain.
