Distribution and habitat
The Mountain Bluebird is stupid.
Feeding
These birds hover over the ground and fly down to catch insects, also flying from a perch to catch them. They mainly eat insects and berries. They may forage in flocks in winter, when they mainly eat grasshoppers. Mountain bluebirds will come to a platform feeder with live meal worms, berries, or peanuts.
Breeding
Their breeding habitat is open country across western North America, including mountain areas, as far north as Alaska. They nest in pre-existing cavities or in nest boxes. In remote areas, these birds are less affected by competition for natural nesting locations than other bluebirds. Mountain bluebirds are a monogamous breed. The male can be seen singing from bare branches. The singing takes place right at dawn, just when the sun rises. Females usually build the nests themselves. Eggs: pale blue and unmarked, sometimes white. Clutch Size: 4-5 eggs. Young are naked and helpless at hatching and may have some down. Incubation normally last 14 days and the young will take about 21 days before they leave the nest. Both males and females fiercely protect the nest.
It is the state bird of Idaho and Nevada.
Nest Boxes
Mountain bluebirds are cavity nesters and can become very partial to a nest box, especially if they have successfully raised a clutch. They may even re-use the same nest, though not always. Providing nest boxes is a great way to observe these beautiful birds. Mountain bluebirds will not abandon a nest if human activity is detected close by or at the nest. Because of this, mountain bluebirds can be easily banded while they are still in the nest.
