Here is some of the important stuff from the article.

Rather than feeding ducks bread, bird enthusiasts can instead offer them treats like:

Halved grapes (be sure to cut them in half to prevent choking)

Cracked corn

Thawed frozen peas

Barley

Oats

Birdseed

Duck pellets

Even with these healthier snacks, Norris says it’s still important to only feed ducks in moderation. If the birds, especially the ducklings, become reliant on people for their food, they may stop foraging or engaging in their other natural behaviors.

“You don’t need to bring a whole bag of seed, a whole bag of grapes,” Norris says, “You don’t want to just throw a whole bunch of stuff at them.” Instead, a handful of snacks should suffice.

This is the first time I've been alerted to a GDPR related issue. Is this becoming a common issue for people in the EU?
