Frequently asked questions

Why does it look like a snake in the water?

Anhingas lack waterproof feathers like ducks, so they stay mostly submerged except for their necks. This swimming style—with only the thin neck visible—creates the striking snake-like silhouette that inspired the 'snakebird' nickname.

Will it attack me or my kids?

No. Anhingas eat fish exclusively, not people. They're shy around humans and will swim away if approached. Maintain the recommended 25-yard distance and you'll have safe, great observations.

How does it catch fish?

With precision spearing. The anhinga dives down and uses its sharp, slender beak to stab prey underwater. Its eyes are specially adapted to see clearly in water, giving it a tremendous hunting advantage.

Can I feed them?

Never. Feeding wildlife changes their natural behavior and damages their health. Observe from a distance and let them hunt on their own.

What time of day should I look?

Early morning or late afternoon offer the best activity. Fish are most active during cooler parts of the day, which is when anhingas hunt most intensively.

Why do they perch on branches with wings spread?

Their feathers absorb water instead of shedding it like ducks. After diving and fishing, they perch in the sun to dry out—this is a normal and critical part of their day.
