PINE SISKIN - Did you know...

Did you know that Pine Siskins can survive in very cold temperatures? The metabolic rates of this species are typically 40% higher than a "normal" songbird. When temperatures plunge as low as -70 degrees C or -94 degrees F, they can accelerate that rate up to five times normal for several hours! (CornellLab)

Photographed in the San Juan Mountains, Colorado.
