Feed the birds.

"Come, buy my bags full of crumbs;
Come feed the little birds,
Show them you care
And you'll be glad if you do
Their young ones are hungry
Their nests are so bare
All it takes is tuppence from you"

This guy was quite content to sit there and feed the birds with the remains of his sandwich. As I framed to shot I noticed the other fellow in the distance feeding the swan. I assume he was feeding the swan, as they can be temperamental things.
