Feeding ducks bread can even prevent them from flying. A high-carb, high-protein diet of mostly bread can cause a wing deformity known as “angel wing” or “airplane wing” that causes the end feathers to stick out sideways instead flat against the body, so that it can’t fly.

Still, humans love feeding ducks. It brings us joy to be able to connect and interact with wildlife in such a way.

Luckily, the Canal and River Trust says we can still feed the ducks, in moderation, with healthier foods that are closer to their natural diet.

The charity even conducted a taste test to see which healthy foods ducks like best. Here’s the list:

1. Frozen peas and pea shoots (don’t cook the peas, but let them thaw)

2. Sweet corn (canned, frozen or fresh)

3. Lettuce or cabbage (kale is their favorite!)

4. Oats (rolled, steel-cut, or instant, they’ll love this treat in moderation)

5. Seeds (bird seed or seeds from the health food market)

6. Rice (cooked or uncooked, in moderation)

To our rescue comes this exquisitely filmed and choreographed “Waltz of the Snowflakes” by San Francisco-based Post:Ballet and members of the Berkeley Ballet Theater. Yes, that is an airport tarmac at the shuttered Naval Air Station Alameda, and the dancers are clearly wearing sneakers rather than ballet shoes.
