Diary for my daughter 30.12.2023 - Northern flicker

Hello, my beautiful daughter ❤️!

Tata here!

Hope you're well!

Tata is fine today! I have now in the morning an Amazon collection from Luton and after nothing planned. Hope that will be a quiet and relaxing day. From tomorrow I will start again 4 nights of work , so it will cach me good some rest. Unless some good offers from Amazon are coming up. Is still dark outside when I wrote this, so I can't say what type of day it will be. Hope it will be a good day. So... let's go to your today story...

Northen flicker 

The northern flicker or common flicker (Colaptes auratus) is a medium-sized bird of the woodpecker family. It is native to most of North America, parts of Central America, Cuba, and the Cayman Islands, and is one of the few woodpecker species that migrate. Over 100 common names for the northern flicker are known, including yellowhammer (not to be confused with the Eurasian yellowhammer (Emberiza citrinella)), clape, gaffer woodpecker, harry-wicket, heigh-ho, wake-up, walk-up, wick-up, yarrup, and gawker bird. Many of these names derive from attempts to imitate some of its calls. It is the state bird of Alabama (known by its colloquial name "yellowhammer").

Taxonomy

The English naturalist Mark Catesby described and illustrated the northern flicker in his book The Natural History of Carolina, Florida and the Bahama Islands which was published between 1729 and 1732. Catesby used the English name "Gold-winged Wood-pecker" and the Latin Picus major alis aureis. When in 1758 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the tenth edition, he included the northern flicker, coined the binomial name Cuculus auratus and cited Catesby's book. The specific epithet auratus is a Latin word meaning "gilded" or "ornamented with gold". The type locality is South Carolina. The northern flicker is one of 13 extant New World woodpeckers now placed in the genus Colaptes that was introduced by the Irish zoologist Nicholas Aylward Vigors in 1825 with the northern flicker (Colaptes auratus) as the type species.

Subspecies

Ten subspecies are recognized, one of which is now extinct, though it may be invalid. The extant subspecies were at one time considered subspecies of two separate species called the yellow-shafted flicker (C. auratus, with four subspecies) and the red-shafted flicker (C. cafer, with six subspecies, five living and one extinct), but they commonly interbreed where their ranges overlap and are now considered one species by the American Ornithologists Union. This is an example of what is referred to in science as the species problem.

Yellow-shafted group

The southern yellow-shafted flicker (C. a. auratus) resides in the southeastern United States. It is yellow under the tail and underwings and has yellow shafts on its primaries. It has a gray cap, a beige face, and a red bar at the nape of the neck. Males have a black mustache. Colaptes comes from the Greek verb colapt, meaning "to peck"; auratus is from the Latin root aurat, meaning "gold" or "golden", and refers to the bird's underwings. As the state bird of Alabama, this subspecies is known by the common name "yellowhammer", a term that originated during the American Civil War to describe Confederate soldiers from Alabama.

The northern yellow-shafted flicker (C. a. luteus; formerly C. a. borealis) resides from central Alaska throughout most of Canada to southern Labrador, Newfoundland, and the northeastern United States.

The Cuban yellow-shafted flicker (C. a. chrysocaulosus) is restricted to Cuba.

The Grand Cayman yellow-shafted flicker (C. a. gundlachi) is restricted to Grand Cayman in the Cayman Islands. The subspecific epithet is named after Cuban naturalist Juan Gundlach.

Red-shafted group

The western red-shafted flicker (C. a. cafer) resides in western North America. It is red under the tail and underwings and has red shafts on its primaries. It has a beige cap and a gray face. Males have a red mustache. The subspecific name cafer is the result of an error made in 1788 by the German systematist Johann Gmelin, who believed that its original habitat was in South Africa among the Xhosa people, then known as the "Kaffirs". As the origin of the subspecies designation is regarded as offensive by some, proposals to change the scientific name of this subspecies to C. a. lathami have been presented to the American Ornithological Society. The Society, in accordance with the rules governing scientific nomenclature, has as of September 2018 declined to support a change of the subspecific name, but may consult with the ICZN on the matter.

The coastal red-shafted flicker (C. a. collaris) has a range that closely overlaps that of C. a. cafer, extending along much of the West Coast of North America from British Columbia to northwestern Mexico.

The dwarf red-shafted flicker (C. a. nanus) resides in western Texas south to northeastern Mexico.

The Mexican red-shafted flicker (C. a. mexicanus) resides in central and southern Mexico from Durango to San Luis Potosí and Oaxaca.

The Guatemalan red-shafted flicker (C. a. mexicanoides) resides in the highlands of southern Mexico and Central America. It is considered by some authorities to be a separate species, the Guatemalan flicker (C. mexicanoides).

The Guadalupe red-shafted flicker (C. a. rufipileus)† is extinct and was formerly restricted to Guadalupe Island, off the northwestern coast of Baja California, Mexico. It was last recorded in 1906. It may be invalid. Vagrants of an extant mainland red-shafted subspecies (which one is unknown) have recently begun recolonizing Guadalupe Island as the habitat improved after the extirpation of feral goats.

Description 

Adults are brown with black bars on the back and wings. A mid- to large-sized northern flicker measures 28–36 cm (11–14 in) in length and 42–54 cm (16+1⁄2–21+1⁄2 in) in wingspan. The body mass can vary from 86 to 167 g (3 to 5+7⁄8 oz). Among standard scientific measurements, the wing bone measures 12.2–17.1 cm (4+13⁄16–6+3⁄4 in), the tail measures 7.5–11.5 cm (3–4+1⁄2 in), the bill measures 2.2–4.3 cm (7⁄8–1+11⁄16 in) and the tarsus measures 2.2–3.1 cm (7⁄8–1+1⁄4 in). The largest-bodied specimens are from the northern stretches of the species' range at the latitude of Alaska and Labrador, while the smallest specimens come from Grand Cayman Island. A necklace-like black patch occupies the upper breast, while the lower breast and belly are beige with black spots. Males can be identified by a black (in the eastern part of the species' range) or red (in the western part) mustachial stripe at the base of the beak, while females lack this stripe. The tail is dark on top, transitioning to a white rump which is conspicuous in flight. Subspecific plumage is variable.

Call and flight

This bird's call is a sustained laugh, ki ki ki ki, quite different from that of the pileated woodpecker (Dryocopus pileatus). One may also hear a constant knocking as they often drum on trees or even metal objects to declare territory. Like most woodpeckers, northern flickers drum on objects as a form of communication and territory defense. In such cases, the purpose is to make as loud a noise as possible, so woodpeckers sometimes drum on metal objects.

Like many woodpeckers, its flight is undulating. The repeated cycle of a quick succession of flaps followed by a pause creates an effect comparable to a roller coaster.

Diet

According to the Audubon field guide, "flickers are the only woodpeckers that frequently feed on the ground", probing with their beak, also sometimes catching insects in flight. They consume nuts, seeds, fruits, and berries, but insects are their main source of diet. They can get 45% of their food from ants alone. Moths, beetles, snails, flies, and butterflies are among the other invertebrates that are consumed. The berries and seeds of poison ivy, poison oak, dogwood, sumac, wild cherry, and grape, as well as bayberries, hackberries, elderberries, and sunflower and thistle seeds, are also consumed by northern flickers, particularly during the winter months. Like other woodpeckers, northern flickers hammer at the dirt to gain access to the nutrient-rich larvae found in underground ant colonies. They have been seen dismantling cow manure in order to consume the insects that reside there. To catch prey, their tongues can dart out 50 mm (2 in) beyond the end of the bill. The northern flicker is a natural predator of the European corn borer (Ostrinia nubilalis), an invasive species of moth that costs the U.S. agriculture industry more than $1 billion annually in crop losses and population control. As well as eating ants, northern flickers exhibit a behavior known as anting, in which they use the formic acid from the ants to assist in preening, as it is useful in keeping them free of parasites.

Influence of diet on offspring

According to an article published in Ibis, the availability of food affects the coloration of feathers in northern flicker nestlings. The article focused on the correlation between melanin spots and carotenoid-based coloration on the wings of nestlings with food stress via indirect manipulation of brood size. The article found that there was a positive correlation between the quality of the nestlings' diet and T-cell-mediated immune response. T-cell-mediated immune response was found to be positively correlated with brightness of pigmentation in flight feathers, but not related to melanin spot intensity.

Habitat

Northern flickers may be observed in open habitats near trees, including woodlands, edges, yards, and parks. In the western United States, one can find them in mountain forests all the way up to the tree line. Northern flickers generally nest in holes in trees like other woodpeckers. Occasionally, they have been found nesting in old, earthen burrows vacated by belted kingfishers (Megaceryle alcyon) or bank swallows (Riparia riparia). Both sexes help with the nest excavation. The entrance hole is about 8 cm (3 in) in diameter, and the cavity is 33–41 cm (13–16 in) deep. The cavity widens at the bottom to make room for the eggs and the incubating adult. Inside, the cavity is bare except for a bed of wood chips for the eggs and chicks to rest on. Once the nestlings are about 17 days old, they begin clinging to the cavity wall rather than lying on the floor. They can create cavities inside homes, especially homes of stucco or weak wooden siding.

Lifespan

A study from 2006 examined the mortality rates of male and female northern flickers over a six-year period using capture-tag-recapture techniques. The researchers observed that only one to two birds out of every 300 adults were 7 or more years old. This observation data correlated well with a mortality model that predicted a 0.6% 7-year survival rate. The data also illustrated that there were no significant differences between male and female survival rates for the general population. The oldest yet known "yellow-shafted" northern flicker lived to be at least 9 years 2 months old, and the oldest yet known “red-shafted” northern flicker lived to be at least 8 years 9 months old.

Reproduction

The northern flicker's breeding habitat consists of forested areas across North America and as far south as Central America. They are cavity nesters which typically nest in trees, but they also use posts and birdhouses if sized and situated appropriately. They prefer to excavate their own home, although they reuse and repair damaged or abandoned nests. Abandoned northern flicker nests create habitat for other cavity nesters. Northern flickers are sometimes driven away from their nesting sites by another cavity nester, the common starling (Sturnus vulgaris).

About 1 to 2 weeks are needed for a mated pair to build the nest. The entrance hole is roughly 5 to 10 cm (2 to 4 in) wide. A typical clutch consists of six to eight eggs whose shells are pure white with a smooth surface and high gloss. The eggs are the second-largest of the North American woodpecker species, exceeded only by the pileated woodpecker's. Incubation is by both sexes for about 11 to 12 days. The young are fed by regurgitation and fledge about 25 to 28 days after hatching.

Wintering and migration

Northern flickers are partial migrants, in which some southern populations are completely non-migratory. Those that do migrate tend to begin their spring migration towards the beginning of April and make their return between September and October. Individuals that breed farther north travel greater distances than their migratory southern conspecifics, often resulting in the convergence of northern and southern populations at wintering sites. This discrepancy likely arises from the northern flickers’ ground foraging behavior, in which prey can only be found in snow-free locations. Furthermore, females tend to winter farther north than males, suggesting that parental investment and division of reproductive labour are key factors in determining individual migratory behavior. Rising temperatures resulting from anthropogenic climate change have been shown to trigger migration prematurely in Northern flickers, as well as many other migratory bird species as evidenced in Sherbrooke, Quebec.

Northern flickers are divided into eastern and western populations by the Rocky Mountains, with each population having a unique migratory pathway. Individuals breeding in the prairie provinces of Canada, the Dakotas, and surrounding U.S. states winter in Texas, Oklahoma, and Arkansas. Those breeding in southern Ontario and Michigan to New England winter from east Texas to the Carolinas, whereas those breeding in British Columbia and the Pacific Northwest winter from central California to Baja Peninsula, Mexico.

During migration, northern flickers may form flocks. Additionally, the species’ propensity for roosting in cavities is not mitigated during migration. On average, 75% of individuals spend their nights in a cavity during migration, even in completely unknown locations. Northern flickers demonstrate a high rate of nest cavity re-use, as opposed to excavating new cavities each year. Furthermore, breeding individuals exhibit intense site fidelity, with pairs consistently returning to the specific nest cavity they used in the previous year.

And that was your today story. Monday, we will learn about New Year's Day. 

Until Monday...
