I realized after standing there for a while on the trail and watching the black bellied whistling ducks flying around in circles what they were doing. The groups of juveniles would take off together and fly around in a small circle and land back in the marsh near their parents. They were practicing for that flight back up north in the spring. They would all whistle together as they flew around me and landed. It was fun to watch them in the early morning fog.
Lots of activity the morning I was there in early January. I hadn’t seen that many whistlers together in the marsh in a long time. They were all very busy feeding and flying around. There were a few young ones left that still had their pin feathers in. I hope some of them stay over through the spring. I miss hearing that whistling sound when they are not here at Circle B Bar Reserve.
