They prefer sites that provide safety from predators and elements, usually choosing cavities at varying heights, often between 5 to 30 feet off the ground.
Nest Construction
Unlike many birds that build elaborate nests, White-breasted Nuthatches take a simpler approach by utilizing existing cavities. However, they line the interior with soft materials such as bark strips, grasses, fur, and feathers. This lining provides insulation and a soft cushion for the eggs and chicks. The male and female typically work together to prepare the nest, with the female arranging the interior.
Egg Laying and Incubation
The breeding season generally begins in early spring. The female lays between 5 to 9 eggs, which are creamy or white with reddish speckles. She is the primary incubator, staying with the eggs for about two weeks until they hatch. During this period, the male plays a crucial role in feeding the female and defending the territory.
Fledging and Parental Care
The chicks are hatched blind and featherless. Both parents are actively involved in feeding the chicks a diet rich in insects, which provides the necessary protein for rapid growth. Fledging occurs approximately 14 to 18 days after hatching. After leaving the nest, fledglings continue to depend on their parents for food and protection for several weeks as they learn to forage and navigate their environment.
Multiple Broods
In some cases, the White-breasted Nuthatch may raise more than one brood per season, particularly when food resources are abundant and environmental conditions are favorable. This capability allows them to take advantage of good conditions and increase their reproductive success.
