The Versicolored Barbet, also known as the Eubucco versicolor, is a small, brightly-coloured bird species that can be found primarily in South America. With their vibrant colours and unique appearance, they are a favourite among birdwatchers and nature enthusiasts alike.

In this article, we will explore some of the key characteristics of this fascinating bird species.

Identification

Field

Identification:

The Versicolored Barbet is easily identified by its brightly coloured plumage. The male bird has a red head with a yellow breast, whilst the female bird has a green head with a yellow breast.

They have a stout, hooked bill, which is black in colour, and a long tail that is also black. They measure between 15 and 17.5 centimetres in length and have a wingspan of around 26 centimetres.

Similar Species:

Although the Versicolored Barbet is quite unique, it can sometimes be confused with other barbet species such as the Lemon-throated Barbet. However, the Lemon-throated Barbet has a yellow throat and lacks the red or green head and yellow breast of the Versicolored Barbet.

Plumages

The Versicolored Barbet is known for its bright and beautiful plumage. However, their plumage can change depending on their age and gender.

Molts:

The Versicolored Barbet undergoes two molts each year – a pre-basic molt and a pre-alternate molt. The pre-basic molt occurs after the breeding season, and the birds shed their breeding plumage and replace it with their non-breeding plumage.

The pre-alternate molt occurs before the breeding season, and they shed their non-breeding plumage and replace it with their bright and colourful breeding plumage. It’s worth noting that juvenile birds have different plumage than adults.

Juvenile males have a green head and a yellow breast, while juvenile females have a green head and a greenish-yellow breast. In conclusion, the Versicolored Barbet is a unique and beautiful bird species that is easily identified by its brightly coloured plumage.

Whilst sometimes confused with other barbet species, the Versicolored Barbet is easily recognizable with its red or green head and yellow breast. It’s fascinating to learn about the two molts the bird undergoes every year, and how it changes its plumage depending on its age and gender.

These characteristics make the Versicolored Barbet a favourite among birdwatchers and nature enthusiasts alike, and a true wonder of the bird world. Systematics History:

The Versicolored Barbet was first described in 1847 by Johann Jakob von Tschudi, a Swiss naturalist.

The species name, Eubucco versicolor, comes from Greek roots, with eu meaning good, bucco meaning cheek, and versicolor meaning variously colored. This refers to the birds bright, multi-colored plumage.

Geographic Variation:

The Versicolored Barbet has a wide range, spanning from western Colombia and eastern Panama all the way to the eastern slopes of the Andes in Bolivia, Peru, and Brazil. This range also includes parts of Ecuador and Venezuela.

Within this range, the bird exhibits geographic variation in its plumage, though this variation is not always easy to discern.

Subspecies:

There are three recognized subspecies of the Versicolored Barbet.

E. v.

versicolor: This is the nominate subspecies found in the eastern Andes of Colombia, Ecuador, and northeastern Peru. E.

v. zonatus: This subspecies is found in the Andes of central and southern Peru.

E. v.

furviventris: This subspecies is found in the western part of the species range, in the Choc region of Colombia and western Ecuador. Related Species:

The Versicolored Barbet belongs to the family Capitonidae, which includes over 50 species of barbets found throughout the New World tropics.

They are closely related to other brightly colored barbets such as the Five-colored Barbet and the Scarlet-banded Barbet. Historical Changes to Distribution:

There have been some historical changes to the distribution of the Versicolored Barbet.

In particular, there has been a decline in the birds population in some areas due to habitat loss and fragmentation. As more land is cleared for agriculture, logging, and other human activities, the birds habitat is becoming increasingly fragmented, making it difficult for populations to persist.

In Colombia, for instance, the bird is known to occur in forested areas of the Magdalena Valley, Cauca Valley, Western and Central Andes, Huila, Cundinamarca, and Santander. However, these areas have undergone significant deforestation over the past few decades, leading to a decline in the birds population.

A study conducted in 2012 by the University of Tolima found that the bird has disappeared from some areas of the country where it was previously known to occur. In Ecuador, the Versicolored Barbet is known to occur in the western part of the country, particularly in the Choc region.

This area has also experienced significant deforestation, leading to a decline in the birds population. According to the IUCN Red List, the bird is classified as Near Threatened due to these threats to its habitat.

In Peru, the Versicolored Barbet is known to occur in the Andes, although the extent of its distribution is unclear. The bird is not listed as threatened in Peru, but it is likely that populations are declining due to habitat loss and fragmentation.

As these threats to the birds habitat continue, conservation efforts are becoming increasingly important. In some areas, reforestation efforts and the creation of protected areas can help to preserve important habitats for the Versicolored Barbet and other species.

The bird’s ranges should be closely monitored for conservation purposes, to ensure that populations remain healthy and stable.

In conclusion, the Versicolored Barbet is a unique, brightly colored bird species found throughout the New World tropics.

With its wide range, geographic variation, and unique plumage, the bird is a favorite among birdwatchers and nature enthusiasts. However, habitat loss and fragmentation have caused declines in populations, leading to concerns about the future of the species.

As such, it is crucial to monitor the bird’s ranges closely, create protected areas and engage in conservation practices to help preserve this beautiful species for future generations. Habitat:

The Versicolored Barbet inhabits humid tropical and subtropical forests, including primary, secondary, and gallery forests.

These birds are primarily found in areas with tall, mature trees, where they can feed on insects and fruit. They can also be found in fragmented forests, although this is less than ideal, and the birds prefer large, contiguous forests.

In the wild, they have been observed at elevations ranging from 300 to 2000 meters. However, different subspecies have slightly different habitat preferences.

E. v.

zonatus, for example, is found at higher elevations than the other subspecies, in the Polylepis forests of the Andes. Movements and Migration:

The Versicolored Barbets are generally non-migratory throughout their range, meaning they do not undertake long-distance migrations to breed or overwinter.

However, there is some evidence that birds in certain areas undertake seasonal movements, likely related to changes in food availability or climatic conditions. In a study conducted in the Ecuadorian Andes, researchers found that the birds move to different elevations depending on the season.

During the rainy season, which runs from December to May, the birds move to the lower altitudes, where there is more fruit available. During the dry season, from June to November, they move to higher elevations, where insect populations are more abundant.

Similarly, in the Magdalena Valley of Colombia, researchers found that the birds moved between different forest types during the year, seeking out areas with more fruit and nectar. One possible explanation for these seasonal movements is the availability of fruit.

Insects are the primary food source of the Versicolored Barbet, but fruit is an important supplement to their diet, providing necessary vitamins and other nutrients. As different trees bear fruit at different times of year, the birds may move to different areas to take advantage of these different food sources.

Another possible explanation is related to changes in temperature and humidity. In the Andes, for example, the temperature and humidity vary depending on altitude, so the birds may move to different elevations to stay within their preferred temperature and humidity ranges.

Overall, while the Versicolored Barbet is generally non-migratory, there is evidence that some populations undertake seasonal movements, likely related to changes in food availability or climatic conditions. Further research is needed to better understand the timing, extent, and causes of these movements.

In conclusion, the Versicolored Barbet is a fascinating bird species that largely inhabits humid tropical and subtropical forests throughout its range, with slight differences among the three subspecies. Whilst generally non-migratory, there is some evidence that the birds undertake seasonal movements between elevations or within forests to take advantage of different fruits and food sources, or to avoid temperature and weather extremes.

Further study is needed to fully understand the patterns and causes of these movements, but they suggest that these bright, colourful birds are adaptable and flexible in their behaviour. Diet and Foraging:

Feeding:

The Versicolored Barbet feeds primarily on insects, including beetles, ants, and termites.

They supplement their diet with fruit and nectar, especially during lean insect times. They usually feed alone or in pairs, although during fruiting events, they may gather in small groups.

Diet:

The diet of the Versicolored Barbet changes seasonally in response to the availability of insect prey and fruit sources. During the breeding season, when insects are more plentiful, their diet is largely composed of insects.

In the non-breeding season, they rely more on fruit to supplement their diet and provide necessary vitamins and other nutrients. Metabolism and Temperature Regulation:

Barbets have a unique metabolism known as torpor.

Torpor is a short-term reduction in metabolic rate, which conserves energy during periods of low food availability or inclement weather. During torpor, the bird’s body temperature drops, and their breathing and heart rates slow down.

Barbets are able to enter torpor quickly and easily, and can remain in this state for up to 16 hours per day. This adaptation allows them to survive in environments with unpredictable food supplies.

In addition to torpor, barbets are also adapted to thermoregulate. This means that they are able to maintain a constant internal body temperature despite changes in their external environment.

Their feathers, for instance, can fluff up to trap warm air near their bodies, helping to keep them warm in cold weather. They can also dissipate heat through their beaks and feet when the weather is hot.

These adaptations help the Versicolored Barbet to survive in the dynamic environment of tropical forests. Sounds and Vocal Behavior:

Vocalization:

The Versicolored Barbet is a noisy bird, with a variety of calls and songs.

Its vocalization is a high-pitched whistle, which is often described as “tsee-tsee-tsee.” The bird also has a variety of other calls, including a chattering chirrrrr and a guttural krroooo. Barbets are thought to have some of the most complex vocalizations of all bird families.

In addition to their calls, they may also engage in territorial drumming rapid repeated drumming on a branch. This is usually performed by males, who drum to establish territorial boundaries and attract mates.

Female barbets may also drum to signal readiness to mate. In conclusion, the Versicolored Barbet is a fascinating bird with unique adaptations that allow it to survive in the dynamic environment of tropical forests.

Its diet changes seasonally in response to the availability of insect prey and fruit sources, and it is able to enter torpor and thermoregulate to conserve energy and maintain a constant internal body temperature. The bird is also a noisy one, with a variety of calls and songs.

Its high-pitched whistle dominates, but it has other calls, including a chattering chirr and a guttural krooo. As we continue to study this bright and colorful bird, we’re sure to learn even more about its unique physiology and vocal behavior.

Behavior:

Locomotion:

The Versicolored Barbet is a perching bird, as are most birds in the order Piciformes. They move around by hopping, climbing, and flying short distances from branch to branch.

Their strong, hooked beak and sharp claws help them to grip tightly onto branches and bark. Self Maintenance:

Barbets have a unique grooming behavior.

They use their beaks to preen their feathers thoroughly, working their way from the head down to the tail. The birds may also use their beaks to scratch and remove any parasites that have lodged themselves on their skin or feathers.

Agonistic Behavior:

The Versicolored Barbet is generally non-aggressive towards other members of its species. However, during the breeding season, males may exhibit agonistic behavior towards other males to assert dominance and secure a mate.

This behavior can include vocal displays and physical confrontations, such as chasing and pecking. Sexual Behavior:

Breeding:

The Versicolored Barbet breeds from March to August, with peak breeding activity occurring in May and June.

The birds form monogamous pairs during the breeding season, and both the male and female are involved in building the nest. The nest is usually located in a cavity of a tree or a hollow bamboo stem, and it is constructed using twigs, leaves, and other plant materials.

After the nest is built, the female lays a clutch of 2-3 eggs. Both parents share the task of incubating the eggs, which takes around 15-18 days.

Once the chicks hatch, both parents are involved in feeding and caring for the young birds until they are ready to fledge, which takes around 21-24 days. Demography and Populations:

The Versicolored Barbet has not been extensively studied in terms of its demography and population dynamics.

However, like many tropical species, the bird faces threats from habitat loss and fragmentation. As forests are cleared for agriculture, logging, and other human activities, the bird’s habitat is becoming increasingly fragmented, making it difficult for populations to persist.

According to the IUCN Red List, the global population of the Versicolored Barbet is currently considered stable, although declines have been reported in some areas. However, the bird is classified as “Near Threatened” due to concerns about the future of its habitat.

Conservation efforts, such as creating protected areas and reforestation projects, can help to safeguard these birds and their habitats for future generations. In conclusion, the Versicolored Barbet’s behavior is fascinating and unique.

From its perching and grooming behaviors to its agonistic and sexual behaviors, this bird is a complex creature that is still being studied by researchers. The breeding behavior of the bird reveals that it is a monogamous species, with both parents sharing the tasks of nest building, incubating, and raising the young.

The bird’s demography and population dynamics are poorly understood, but there are concerns about its future due to habitat loss and fragmentation. Protecting the bird’s habitat is essential to the conservation of this beautiful and colorful species.
