The Black-headed Woodpecker, or Picus erythropygius, is a stunning bird species that can be found in the Asian continent. These woodpeckers are fascinating creatures with unique characteristics and behaviors, making them of great interest to bird enthusiasts.

Identification

Field Identification

The Black-headed Woodpecker is a medium-sized bird that measures up to 24 cm in length. Males typically have a bright red crown and a black hood on the head, while the females lack the red crown and have a brownish-black hood instead.

Both sexes have a white belly, a black back, and wings with white spots on them.

Similar Species

One of the birds that are often confused with the Black-headed Woodpecker is the White-backed Woodpecker, which is very similar in appearance. However, the White-backed Woodpecker can be distinguished by its black back and white rump, while the Black-headed Woodpecker has a completely black back.

Plumages

The Black-headed Woodpecker undergoes two molts throughout its life – the juvenile molt and the adult molt.

Juvenile Molt

During the juvenile molt, which occurs when the bird is about 3 months old, the young birds lose their down and grow their first feathers. At this stage, the young woodpeckers have a duller plumage compared to the adults.

Their crowns are brownish-red instead of bright red, and their hoods are brownish-black instead of black.

Adult Molt

The adult molt takes place once a year in the fall, during which the birds replace their old feathers with new ones. This is often when the red crown of the males is at its brightest, making it one of the best times to observe these incredible birds.

Conclusion

The Black-headed Woodpecker is a remarkable bird with unique physical characteristics that make it stand out from other bird species. With its striking coloration, it is a bird that is easy to recognize, but it also has its own set of challenges when it comes to identification.

Diet and Foraging

Feeding

The Black-headed Woodpecker is primarily an insectivore and relies heavily on insects for its diet. They also consume other invertebrate prey, such as spiders, centipedes, and snails.

Additionally, they occasionally feed on fruits, nuts, and seeds. The Black-headed Woodpecker is an active forager that uses its strong, chisel-like bill to drill into trees and branches in search of prey.

They also use their long tongues, which can be up to four times longer than their bill, to extract insects from crevices and holes in wood.

Diet

The Black-headed Woodpecker’s diet varies depending on the season and availability of prey. In the breeding season, they tend to consume more insects, including ants, beetles, and caterpillars, while in the winter months, their diet shifts to include more fruits and seeds.

In some areas, the Black-headed Woodpecker has also been observed feeding on pine and spruce seeds, particularly during poor insect years. They have also been known to feed on the sap of trees, which may be an important source of nutrients during times when insect prey is scarce.

Metabolism and Temperature Regulation

The Black-headed Woodpecker has a high metabolism and requires a constant supply of food to maintain its energy levels. They are able to regulate their body temperature through several mechanisms, including panting, gular fluttering, and perching in the shade.

Panting is a common behavior observed in woodpeckers during periods of intense heat, where they open their bills and rapidly move their tongues to increase air flow across their respiratory surfaces, which helps to dissipate heat. Gular fluttering is another mechanism used to dissipate heat, in which the bird rapidly vibrates the muscles in its neck, causing heat to be released from the body.

Finally, perching in the shade is a behavior used to seek cooler temperatures during periods of intense heat, where the bird positions itself in the shade of a tree or other object.

Sounds and Vocal Behavior

Vocalization

The Black-headed Woodpecker has a distinct and recognizable vocalization, which is characterized by a series of loud and distinctive “klee-klee” calls. These calls are often heard during the breeding season when the birds are establishing territories and communicating with each other.

In addition to their “klee-klee” calls, Black-headed Woodpeckers also have a variety of other vocalizations, including drumming and rattling sounds. Drumming is a rapid and rhythmic tapping sound that is produced by the woodpecker striking its bill against a tree or other object.

Rattling sounds are produced by a rapid series of low-pitched calls and are used primarily during courtship and territorial disputes. Black-headed Woodpeckers may also engage in visual displays during the breeding season, including tail-fanning and head-bobbing.

Tail-fanning is a behavior where the bird fans its tail while perched, displaying the white feathers on the underside of its tail. Head-bobbing is a behavior where the bird bobs its head up and down repeatedly, which may be used as a signal of aggression or as part of the courtship display.

Conclusion

The Black-headed Woodpecker is a fascinating bird species with unique characteristics and behaviors. Their diet of insects and other invertebrates helps to control populations of these organisms, making them important in their ecosystem.

Their ability to regulate their body temperature through various mechanisms is also fascinating, and their distinctive vocalizations and displays add to their charm. Overall, the Black-headed Woodpecker is an important bird species that deserves our attention, respect, and protection.

Behavior

Locomotion

The Black-headed Woodpecker is an arboreal species, meaning that it spends most of its time in trees. As such, it is well adapted to moving vertically up and down tree trunks, using its strong legs and claws to grip onto the bark.

Black-headed Woodpeckers are also able to move in any direction on the tree trunk, including headfirst. Their stiff tail feathers provide additional balance and support while climbing.

Self Maintenance

Black-headed Woodpeckers are fastidious about maintaining their feathers and keeping them clean. They spend several hours a day preening their feathers with their bill, removing dirt and debris and redistributing natural oils to keep their feathers in optimal condition.

Agonistic Behavior

Black-headed Woodpeckers are fiercely territorial birds and will defend their territories against other birds of their own species as well as other species. Agonistic behavior includes vocalizations and physical displays, such as holding the feathers on their heads erect.

They also engage in drumming and rapping sounds on deadwood or trees, which can be heard for long distances and is a way to communicate with other woodpeckers.

Sexual Behavior

During the breeding season, Black-headed Woodpeckers engage in courtship displays, which include head-bobbing and tail-fanning. Males may also engage in aggressive displays, such as chasing and gripping each other’s bills, to establish dominance and defend their territory.

Once a pair bonds, the male will help the female excavate a nest cavity in a tree trunk or branch. Both male and female will take turns incubating the eggs and feeding the young.

Breeding

Black-headed Woodpeckers breed once per year, typically in the late spring or early summer. Males attract females using vocalizations and displays, and pairs will bond for the breeding season.

The nesting site is typically a natural cavity in a tree trunk or branch that has been excavated by the birds themselves. Females lay 4-6 white, oval-shaped eggs, which hatch after about two weeks.

Both parents will help raise the young, bringing them food in the form of insects and other prey items. The young birds will leave the nest after about 3-4 weeks and will be independent shortly after.

Demography and Populations

The Black-headed Woodpecker is considered a species of least concern by the International Union for Conservation of Nature (IUCN), although some subspecies may be threatened due to habitat loss and fragmentation. Populations of Black-headed Woodpeckers have declined in some areas due to habitat loss resulting from deforestation, particularly in Europe.

In Russia, the population is stable, but the species may be affected by changes in land use practices and other threats. Conservation efforts aimed at protecting the Black-headed Woodpecker should focus on preserving and restoring its habitat, particularly mature forests with plenty of old trees and deadwood.

Maintaining forest connectivity and protecting key habitat areas is also important for ensuring the survival of different subspecies of the Black-headed Woodpecker. Additionally, understanding the behavior and breeding ecology of the species is crucial for conservation efforts and the long-term survival of the Black-headed Woodpecker.

Conclusion
