It is a migratory bird with an extremely sporadic winter range. The female remains on the nest continuously, fed by the male throughout brooding.Īt our cabin near Rio we are feeding a flock about 50 pine siskins. We are looking forward to counting birds including pine siskins on the Great Backyard Bird Countbeing held on February 12-15th. The pine siskin ( Spinus pinus) is a North American bird in the finch family. The only other confirmation in south central Wisconsin was a siskin family feeding at a feeder in Montello. Siskins can begin nesting in April and they protect their eggs from cold by building a highly insulated nest. In the first year of the Atlas II project Charles Henrikson photographed a nest being built at the UW Arboretum in a red pine, and Andrea Szymczak located a nest, also in a red pine, in southeast Jefferson County. In the first Breeding Bird Atlas of Wisconsin there was a record of a nesting in Dane and Columbia County. One of the largest pine siskin observations was on Octoat Cedar Grove Hawk Research Station (Sheboygan County) when Dan Berger reported 50,000 pine siskins moving south!įollowing a large irruptive winter flight, some individuals may stay near a dependable food source and breed far south of the normal breeding range. Banding data suggest that some birds may fly west-east across the continent while others move north-south. Though they’re erratic, these movements may not be entirely random. Every couple of years, pine siskins make unpredictable movements called irruptions into southern and eastern North America. Sam Robbins wrote in Wisconsin Birdlife that pine siskins in southern Wisconsin are uncommon to fairly common winter residents, and rare in summer. The energy in that amount of food could get them through 5–6 nighttime hours of sub-zero temperatures. Pine Siskins can also temporarily store seeds totaling as much as 10% of their body mass in a part of their esophagus called the crop. When temperatures plunge as low as –70☌ (–94☏), they can accelerate that rate up to five times normal for several hours. They also put on half again as much winter fat as their Common Redpoll and American Goldfinch relatives.

Pine Siskins get through cold nights by ramping up their metabolic rates-typically 40% higher than a “normal” songbird of their size. At our bird feeders, they prefer sunflower fines or hulled sunflowers. Pine Siskins have a fondness for the seeds of pines and other conifers like cedars, larch, hemlock, and spruce. They are about the same size as American goldfinches, and frequently feed with them. Sometimes you hear them before you see them since they are gregarious, foraging in tight flocks and twittering incessantly to each other, even during their undulating flight!

The Siskin is a year-round resident primarily in the coniferous forest in parts of southern Canada, northern New. It is distinguished by brown streaking and yellow patches at the base of its tail and wing flight feathers. Pine siskins are brown and very streaky birds with subtle yellow edgings on wings and tails. The Pine Siskin ( Carduelis pinus) is one of the small thistle-seed loving finches that flock to bird-feeders in the winter.
