Last week we banded this Gray Catbird.
This bird’s crossed bill is a physical deformity it was born with. This condition often impacts a bird’s ability to feed or preen, which can significantly affect its chance of survival.
HOWEVER, we caught this bird again today and he has put on a gram of fat in the last week! He seems to be thriving while overcoming this adversity.
Just another amazing story of resilience from one of our favorite birds.

You've seen families at the park: "Let the kids feed the ducks! They love bread!"

It's a beloved tradition. Grandparents teach it. Parks even sell stale loaves. It is slowly deforming and killing waterfowl.

🛑 THE PROBLEM: "The Bread Myth"

Bread looks like a treat. Ducks DO eat it eagerly. But here's what bread actually does to waterfowl:

- Zero nutritional value — it fills their stomachs with empty carbs while they starve of the protein and vitamins they need for feather growth and flight
- Causes "angel wing" — a permanent deformity where wing feathers twist outward and the bird can never fly again. It's irreversible after adolescence
- Uneaten bread sinks, rots, and fuels algal blooms that choke oxygen from the water — killing fish and creating botulism outbreaks that poison entire flocks
- Ducks conditioned to bread lose foraging instincts, crowd unnaturally into small areas, and spread disease through concentrated droppings

Parks that allow bread feeding see higher rates of avian cholera, duck plague, and aspergillosis. The "cute" feeding frenzy is a disease incubator.

✅ THE SOLUTION: The Safe Feeding Station

Bring a small bag of SAFE foods that match what waterfowl actually need:

OFFER THESE:
✅ Defrosted frozen peas or corn (cheap, nutritious, ducks love them)
✅ Chopped lettuce or kale torn into small pieces
✅ Plain oats or oatmeal (uncooked, no flavoring)
✅ Halved grapes (cut lengthwise to prevent choking)
✅ Cracked corn or birdseed from any hardware store
✅ Plain cooked rice (no salt, no seasoning)

NEVER OFFER:
❌ Bread, crackers, or chips (malnutrition + angel wing)
❌ Popcorn or pretzels (salt damages kidneys)
❌ Chocolate or candy (toxic)
❌ Moldy food of any kind (aspergillosis is fatal)

🔋 TIMING: Late winter flocks are at their most nutritionally stressed. Natural food sources are at their lowest right now in February — what you bring to the pond this week matters more than any other month.

💡 Pro Tip: Scatter food in the water, not on the bank. It reduces aggressive crowding and lets shy birds eat safely.
