Bearded woodpecker

Dendropicos namaquus

Photo by José Kemp (PBase)

Common name:
bearded woodpecker (en); pica-pau-de-bigodes (pt); pic barbu (fr); pico barbudo (es); Namaspecht (de)

Taxonomy:
Order Piciformes
Family Picidae

Range:
This species is found in sub-Saharan Africa, from the Central African Republic and Sudan to Senegal and south to South Africa, only being absent from the dense rainforests of the Congo basin.

Size:
These birds are 25-28 cm long and weigh 67-98 g.

Habitat:
The bearded woodpecker avoids dense forests, typically being found in deciduous woodlands, dry savannas, wooded grasslands and dry scrublands with some large trees. They are present from sea level up to an altitude of 3.000 m.

Diet:
They probe the bark of the trees in search of beetle larvae and pupae, caterpillars, termites, and spiders. They are also known for occasionally hunting lizards.

Breeding:
Bearded woodpeckers can breed all year rounds, varying between different parts of their range. The nest is an oval-shaped hole excavated by both sexes on a large tree, either dead or alive, usually 2-20 m above the ground. There the female lays 2-4 eggs, which are incubated by both sexes for 13 days. The chicks are fed by both parents and fledge around 27 days after hatching, only becoming fully independent 1-2 months later.

Conservation:
IUCN status - LC (Least Concern)
This species has a very large breeding range and is reported to be widespread and locally common but seldom numerous. The population is suspected to be stable in the absence of evidence for any declines or substantial threats.

Red-cockaded woodpecker

Picoides borealis

Photo by Matthew Hacker (Wikipedia)

Common name:
red-cockaded woodpecker (en); pica-pau-de-faces-brancas (pt); pic à face blanche (fr); pico de Florida (es); kokardenspecht (de)


Taxonomy:
Order Piciformes
Family Picidae


Range:
This species is endemic to the Unites States, with scattered populations being found in the south-eastern parts of the country, especially in Florida and South Carolina but as far north as Virginia ans as far west as eastern Texas and Oklahoma.


Size:
These birds are 18-23 cm long and have a wingspan of 34-41 cm. They weigh 40-56 g.


Habitat:
The red-cockaded woodpecker is found in fire-sustained open pine-forests, mostly longleaf pine Pinus palustris, but other species of southern pine such as shortleaf P. echinata, slash P. elliotti, or loblolly P. taeda pines are also acceptable. They are present from sea level up to an altitude of 500 m.


Diet:
They are omnivorous, eating adult and larval arthropods, especially beetles and ants, but also seeds, nuts and fruits.


Breeding:
Red-cockaded woodpeckers are cooperative breeders, lives in small family groups composed of one breeding pair and several helpers. These helpers are usually the male offspring from previous breeding seasons and help incubate the eggs and feed the chicks. They breed in April-July, nesting in cavities excavated into old living pines, often selecting trees infected with the red heart fungus, which softens the wood. The female lays 2-5 white eggs, which are incubated for 10-13 days. The chicks fledge 25-29 days after hatching, but remain with the family group for at east 5 months.


Conservation:
IUCN status - VU (Vulnerable)
This species has a large but fragmented breeding range. The population was originally distributed throughout the south-eastern united states, but it is now restricted to about 30 populations totalling 9.000-11.000 individuals, having undergone a large decrease of 26% per decade over the last 4 decades. However, some of the populations are now stable or increasing as a result of intensive management. The main threats to the red-cockaded woodpecker are habitat destruction and fragmentation caused by long-term clearance, inbreeding depression due to the small size of some of the small and isolated populations, and infestations by southern pine beetle Dendroctonus frontalis, which increase food availability, but kill the tree reducing the available nesting sites. Competition by pileated woodpeckers Dryocopus pileatus and reduced fire management due to expanding human populations may also have a negative impact.

Common name:

Taxonomy:
Order Piciformes
Family Picidae

Range:
This species is endemic to the island of Hispaniola, in the Caribbean, being found in both Haiti and the Dominican Republic.

Size:
The Hispaniolan woodpecker is 20-25 cm long. Males tend to be larger in this species, weighing 83-92 g while females weigh 65-75 g.

Habitat:
These birds a found in virtually any wooded habitat within Hispaniola, from sea level up to an altitude of 2.400 m. They can be found in both wet and dry forests, in pines and hardwoods, in thorny scrub, coffee plantations, palm trees, cacti and mangroves. This species achieves its highest densities in woodlands interspersed with agricultural land, especially where crops are associated with scattered palm trees.

Diet:
Hispaniolan woodpeckers mostly eat insects and other arthropods, including beatles, butterflies, ants, scorpions and spiders. They also eat small Anolis lizards, fruits and seeds. They typically forage alone or in pairs, searching for food in the trees, 7-20 m above the ground.

Breeding:
These birds breed in February-July. They nest in loose colonies of 5-20 pairs, with both members of each pair digging holes in dead palm trees or in the trunks of live trees, cacti or even telephone poles. They are also known to nest in hollow cliffs. The female lays 4-6 eggs which are incubated for 13-14 days. The chicks are fed by both parents but the fledging period was not yet recorded.

Conservation:
IUCN status - LC (Least Concern)
Although the global population size is yet to be quantified this species is described as common over its restricted breeding range. This species may be the target of persecution by farmers and plantation workers due to the damage they can cause to cocoa plantations.

Range:
This species cccurs in the United States, the mountains of extreme southwestern New Mexico and southeastern Arizona, and in Mexico through the Sierra Madre Occidental of Sonora, Chihuahua, Sinaloa, Durango, Nayarit, Jalisco, Colima, Zacatecas, and Michoaca.

Size:
This small woodpecker is 18-20 cm long and has a wingspan of 36 cm. They weigh 34-51 g.

Habitat:
The Arizona woodpecker is restricted to Madrean woodland and forests riparian areas, where they are especially dependent on evergreen oaks and adjacent riparian woodland, occuring in mountain oak or pine-oak habitats. They are found at altitudes of 1.200-2100 m.


Diet:
They mostly eat adult and larval insects, especially beetle larvae. They also take fruits and acorns.

Breeding:
These birds breed in April-May. They nest in cavities, excavated by the male and possibly also the female, in dead wood in evergreen oaks, sycamores, maples and cottonwoods, riparian walnuts, and occasionally in agave stalk. There the female lays 2-4 white eggs which are incubated by both parents for 14 days. The chicks are brooded and fed by both parents and fledge 24-27 days after hatching. In the first weeks after fledging the chicks may continue to receive food from parents.

Conservation:
IUCN status - LC (Least Concern)
Although this species has a restricted breeding range, the population of 200.000 individuals is believed to be increasing, so the Arizona woodpecker is not threatened at present. This species is dependent on healthy oak and riparian forests and being one of the primary cavity nesters in the area, it is responsible for providing nest sites for a large number of additional species.

Range:
During the breeding season this species is present throughout Europe, with the exceptions of Ireland and Iceland. They also breed along the southern regions of Russia, all the way to the Pacific coast. In Asia they are also present in northern China and Mongolia. An isolated population breeds in the Kashmir region both in India and China. The European population winters in Africa, along the Sahel belt, south of the Sahara. The Asian populations winter in the southeast of the continent, from India in the west, through Myanmar and Thailand, and into southern China.  The populations in northern Morocco, Algeria and Tunisia are resident and stay in that region all year round.

Size:
This small woodpecker averages 17 cm in length and has a wingspan of 26 cm. Males and females are similar in size and weigh around 38 g.

Habitat:
The wryneck mostly uses woodland and farmland, avoiding steppes, deserts, mountains and wetlands. It does not favour dense or tall forests, preferring fringes, open woodlands, clearings, or, especially, parks, orchards, cemeteries and large gardens. Prefers deciduous to coniferous trees, and is less interested in trunks than in branches, often fairly close to ground. During migration these birds can use a variety of sandy habitats, even deserts, where they forage on ants. While wintering, these birds can be found in broad-leaved or thorn scrubland, semi-desert, and cultivations.

Diet:
Feeds almost exclusively on ants, both adults and larvae. Uses its long, glutinous tongue to remove the ants from their holes.

Breeding:
Wrynecks usually nest in a natural hole in a tree, but they will also make use of holes in walls and nest boxes. They lay up to 10 pale grey-green eggs, most commonly in May, which are incubated by the female for 12-14 days. The chicks are fed ants by both parents and fledge about 3 weeks after hatching.

Conservation:
IUCN status - LC (Least Concern)
The species has a very wide range, and a global population of over 5 million individuals. Although the population may be suffering a small decline, there are no significant threats afecting its survival at present.
