Bluebirds of a feather

This feathered foursome caught in a US snowstorm are eastern bluebirds, the most widespread of the three types of bluebird. They’re found in in grasslands, forest clearings and meadows across a huge area from southern Canada to Central America.

All bluebirds are cavity nesters, making their homes in the hollows of trees, often in holes vacated by bigger birds like woodpeckers. Nest boxes have also played a big part in helping the eastern bluebird population rebound after a steep decline in the early 20th century, due to reduced habitat and the introduction of non-native species, which compete with them for nesting holes.
