In the dim light of daybreak at first glance I thought the diminutive duck was somehow related to the female mallard. Both were inconspicuous and camouflaged amongst the cattails. Mrs. Mallard was preening and standing on one leg, a thing birds do to regulate their body temperature, and Mystery Duck was actively diving all around her. As the light grew brighter with the rising sun it was easy to see that they weren’t at all akin; Mystery Duck’s bill was shorter and chunkier when compared to the Mallard’s bill, Mystery was half her size, and its perky cotton white tail feathers were unmissable. The Mallard flew off eventually and our Mystery then traveled away, deeply diving and then reemerging some distance further, staying close to the shoreline and always well hidden.
Side-by-side comparison: Pied-billed Grebe, left, female Mallard, right.
The Pied-billed Grebe is rarely seen breeding in Massachusetts any longer and is listed as endangered in nearly every New England state. Rhode Island considers the Pied-billed extirpated (locally extinct). The reason for their decline is low breeding numbers and wetland degradation. Their feathers are thick and soft and were used to make hats and earmuffs during the 19th century. Wantonly hunted to near extinction, Pied-billed Grebes never fully recovered in our region. As wetlands have given way to development, the Pied-billed Grebe’s numbers continue to decline dramatically. They are extremely sensitive to human disturbances, and, too, are less likely to be seen as it is a nocturnal bird, traveling mostly during the night.

A fun fact about the marsh-nesting Pie-billed is that both male and female contribute to building what at first appears to be a floating nest in vegetation, near open water. The nest is actually a platform anchored to plant stalks.
I wonder if this Pied-billed is a fall migrant or if on Niles Pond, Pied-billed Grebes were nesting this season. Has anyone else documented or seen a Pied-billed Grebe at Niles Pond during the past few months?
