Sexual Behavior:

The Brown-backed Woodpecker is a monogamous species, meaning that they form pair bonds during the breeding season. Males will engage in courtship behavior to attract females, usually by drumming on trees and singing.

Once pair bonds have been established, the birds will work together to construct a nest. Both the male and female take part in nest construction, with the male being responsible for excavation and the female for lining the nest with materials such as grass, feathers, and other soft materials.

Breeding:

The Brown-backed Woodpecker breeds once a year, typically from April to June. The male and female birds work together to excavate a nesting cavity in a tree, usually around 5-8 meters above the ground.

The cavity is lined with soft materials such as grass, feathers, and other materials. The female will lay 2-3 eggs, which she will incubate for around 12 days.

During this time, the male will bring food to the female and help to incubate the eggs. Once the eggs hatch, both parents will take turns feeding and caring for the young.

The chicks will fledge from the nest after around 30 days and become independent from their parents after a few weeks. The Brown-backed Woodpecker may breed in abandoned nest cavities of other bird species, such as barbets or woodpeckers.
