Black bellied whistlers across the marsh in the fog.

Later I could see some of them fighting.

I can’t stop taking pictures of these charismatic ducks. They are very loud when they are all whistling across the marsh. They were very busy the morning I was at Circle B Bar Reserve in late December.

Coming in for a landing.

Above is a short video I took recently of the whistlers. You can hear the sound all over the park when they are active early in the morning.
