Due to its limited range and vulnerability due to habitat loss and fragmentation, it is crucial to ensure the conservation of their habitat and its availability for the future population of the Arabian woodpecker.

Behavior

Locomotion

The Arabian Woodpecker moves around trees via climbing, hopping, and clinging. Its sharp, recurved claws help it to cling onto bark while it is searching for insects, and its zygodactyl feet are specially designed to provide a stable grip on tree trunks.

In flight, their wings make a distinctive undulating pattern that helps distinguish them from other species.

Self Maintenance

Woodpeckers molt their feathers every year and rely on preening to keep these feathers in good condition. The Arabian Woodpecker preens itself by collecting oil from a gland near its tail and spreading it on its feathers.

Preening helps to keep the feathers clean and aerodynamic, improving the bird’s ability to fly.

Agonistic Behavior

Intraspecific agonistic behavior, or aggressive behavior towards other individuals of the same species, is common among woodpeckers. This behavior serves to establish and defend territories, attract mates, and establish social hierarchies.

The Arabian Woodpecker will use a variety of displays, including wing flapping, bill-pointing, and fanning of tail feathers, to communicate aggression or dominance to other woodpeckers.

Sexual Behavior

During the breeding season, the Arabian Woodpecker engages in courtship behavior, including drumming on trees to establish a territory and attract a mate. The male bird will also communicate with the female through calls and posturing.

The birds form monogamous pair bonds, and both parents will engage in nest building and raising offspring.

Breeding

The Arabian Woodpecker is a cavity-nesting bird, using natural tree cavities or excavating its own hole in a tree to build its nest. The bird’s nesting season typically begins from February to April.

The male Arabian Woodpecker will select a suitable tree and excavate a hole in which the female will lay eggs. After hatching, both parents take turns incubating and feeding the chicks.

The nest cavity is deep enough to keep the eggs and chicks out of sight, thus providing protection against predators. The eggs are incubated for about two weeks, and after they hatch, the chicks are fed insects by both parents.

The young birds will remain in the nest for several weeks until they are ready to fledge, after which they will leave the nest.

Demography and Populations

The Arabian Woodpecker is considered a vulnerable species, and its population is decreasing due to habitat loss and fragmentation. The bird’s restricted range has made it susceptible to environmental stressors, such as water scarcity, climate change, and habitat fragmentation.

Its vulnerability to habitat loss has led to conservation efforts focused on habitat protection and restoration.
