Female birds need to eat calcium to have enough of the mineral to lay their eggs. But it can be hard to find enough of it to eat in nature. We can help our backyard birds by offering them some extra calcium in bird feeders and by recycling our used egg shells.

Most of the time, a Ruby-crowned Kinglet is neither ruby nor regal. A tiny songbird washed in faded olive-green, the male shows a hint of crimson atop of his head — hardly a ruby crown. But don’t forsake the kinglet for flashier birds. When courting a female or dueling with another male…

A typical songbird belts out its song between 1,000 and 2,500 times per day. Even though most bird songs last only a few seconds, that's a lot of warbling! A Yellowhammer, a European bunting, may sing over 3,000 times a day. But the Yellowhammer doesn't even come close to the North…

The Arctic is still wintry when male Snow Buntings return to nesting areas in April. There's a big benefit to arriving early enough to claim a prime nest cavity in a rock face or under boulders, where it will be safer from predators. Nesting in chilly rock cavities means extra care must be…
