#1. Pine Siskins become considerably plumper through accumulation of fat with the onset of winter. Each bird can pack enough seeds into its expandable esophagus to support itself through five hours of rest at –4º Ftemperatures.
#2. A siskin may take up a position near a bird that is eating larger seeds like striped sunflower to pick up dropped pieces and will even defend the position against other siskins.
#3. The Pine Siskin is the most common of the “winter finches” to be foundat your feeders…but not every year. An “irruption” migration usually takes place every two or three years that can bring large numbers of Siskins to
your backyard.
#4. Pine Siskins, like most northern finches, are fond of salt. They seek out natural salt licks and in the winter they can be found along highwayseating the salt used to melt ice and snow.
