January 30, 2010 – A pair of Trumpeter swans surrounded by a number of Canada geese and a a few Mallard ducks were taking advantage of the open waters near the boat docks at the headquarters at the Willow Slough Fish and Wildlife Area near Morocco Indiana this past week. A submerged aerator system sending bubbles of air to the surface keeps some small pools open and ice free. The open water attracts waterfowl during the winter when the rest of J.C. Murphey Lake is locked in ice. Getting a close look at the pair of swans, that have been seen at the lake for some months now, show that one of the birds does not have the usual black legs and feet that is normally seen on an adult Trumpeter. While photographing the Trumpeters at some distance this past August I noticed the yellow colored legs on one of the birds and assumed it was a juvenile. I was told at the headquarters at Willow-slough this past week that the swan with yellow legs was believed to be leucistic. Leucism is a genetic mutation that causes a reduction of pigments. We see the abnormality in mammals, birds, and even in reptiles. A few times a year while great flocks of Starlings are feeding in fields it is not uncommon to see a flash of white from the wings, tail, or the head of one of the birds in the flock. The birds with white feathers are missing the normal dark colors of the Starling and are considered leucistic. The young cygnet (baby swan) that is leucistic is bright white and the non leucistic young Trumpeter is gray. The leucistic birds end up with yellow legs and feet as adults Trumpeters. These rare leucistic Trumpeter swans have been reported and are still occasionally seen in Ontario. The leucistic swans are bit more common in the Rocky Mountain population and are also seen in the Yellowstone summer population.
March 13, 2019 – The elegant and quite handsome male Northern pintail duck in its’ full breeding plumage stands out among the other waterfowl. During the breeding season the male pintail has elongated tail feathers and a striking overall enhanced and well defined coloration of gray, bright-white, coal-black, and chocolate- brown. The breeding male pintail is a sleek long-necked duck with a blue bill outlined in black, with iridescent green or an almost black speculum on the secondary wing feathers that are visible in flight.
The Northern pintail is a long distance migrant with a winter range stretching from Central America, Mexico, Cuba, and coast-to-coast across the southern half of the United States. During the breeding season pintail ducks nest on the Great Plains east across the Great lakes and north throughout Canada and Alaska. According to the National Wildlife Federation “In general, pintails breed in prairie habitats-open country near lakes, rivers, and wetlands dominated by low vegetation and small, shallow water bodies, such as prairie potholes of the Midwestern United States.”
This is the time of the year, late winter, when we see those migrating Northern pintail ducks in our area. Most often flocks of pintail are in the company of many other migrating species of ducks and geese that are slowly working their way north waiting for that exact moment to continue that journey to their summer nesting habitat. Staging can last a number of weeks, the ducks use the open shallow waters of our wetlands and the flooded agricultural fields for resting, feeding, and pairing up for the nesting season. This is when we have the opportunity to see that beautiful plumage of the male Northern pintails as they swim, feed, and rest and try to impress the females.
