This morning, on our usual loop through the southern portion of South Platte Park, a friend and I encountered 65 buffleheads, perhaps the largest number I have ever observed at the refuge. Easily identified by their small size, short bill, distinctive plumage and diving behavior, they are among our more attractive winter ducks.
Usually seen in pairs or small flocks, these "cute" ducks tend to be quite active, scooting across the surface or diving for their meals. The latter consist primarily of aquatic invertebrates though they sometimes nibble on aquatic vegetation as well.
Our winter guests may linger into mid April but most will be gone by then, heading north to breeding areas in Canada and Alaska. I wish them a safe journey and look forward to their return next autumn.
