Identification

Field

Identification:

The bird stands about 40cm tall, making it one of the largest woodpeckers in Europe. Its black and white plumage is striking, with a bright red crown on the male distinguishing it from the female.

The black woodpecker also has powerful wings, broad enough to support its body. Similar Species:

The Black woodpecker shares features with other woodpeckers in the region, such as the Great Spotted Woodpecker.

Still, its size, bright red crown, and almost entirely black plumage differentiate it from these other species.

Plumages

The Black Woodpecker has different plumages throughout its life cycle, and the most prominent changes occur during molts. There are two types of molts that the bird undergoes.

Juvenile – During this period, the bird is plain black, with no white feathering. Its plumage will begin to show white feathering soon.

Adult summer – The bird’s feathers are pitch black apart from the black and white barred wings, with the crimson forehead distinguishing males from females. Adult Winter – This period sees the bird’s black and white barring become more profound, and the bird’s feathers take a slightly browner tinge on its flanks and sides.

Molts

The black woodpecker molts twice annually, with the first molt occurring from April to June, while the second molt usually occurs between September and December.

First Annual Molt

This is called the pre-basic molt and occurs during the bird’s first year of life. During this molt, the hatchling’s entire feather is replaced, which is essential for juveniles who rely on perfect feathers for first flights.

Second Annual Molt

The Black Woodpecker’s second molt is referred to as the basic molt. It occurs after the bird’s first breeding activities.

During this period, the bird’s old worn-out feathers are replaced with fresh, functional ones. The Black Woodpecker’s molting process takes a few days to weeks, during which the bird loses almost all its feathers before the new ones grow.

The molt process can affect adults in their plumage and characteristics, making it a challenge to identify them.

Conclusion

The black woodpecker is a fascinating bird to study, considering its size, plumage, and molt characteristics, and it continues to intrigue bird enthusiasts and nature lovers.
