From 8-year old Hilda’s diary:

This afternoon Grandfather took me to Golden Gate Park. There is a pretty little lake there with boats on it and ducks swimming in it and geese too and black birds called coots and you can buy bags of bread to feed them. Grandfather bought a bag for the birds and a bag of cookies for me and then he took one of the little boats with a boy to row it and it was so much fun. The ducks and geese came right up to our boat and one duck had a row of little babies swimming in back of her single file, just the way we march in school when we have a fire drill.

Like Hilda, I have fond memories of feeding the birds at Golden Gate Park. Instead of buying it, we would bring stale bread from home.
