Mountain Chickadee
Mountain Chickadees incubate their eggs almost a full week longer than their near-twins, the Black-capped Chickadees do. Some scientists think this is an evolutionary change that’s been made possible by Mountain Chickadees’ tendency to nest inside harder-walled trees, which are safer from predators.
