In this article, we will delve deeper into the identification of the Black-breasted Buttonquail, its plumages, molts, and similar species to help you get to know this mysterious bird better.

Identification

Field Identification

The Black-breasted Buttonquail is a tiny bird, measuring about 18-22 cm in length. This bird species features a distinctive black and white barring on its wings and small legs.

The males have a brownish crown and a black breast, while the females’ coloring is more olive-brown, with a rusty-colored crown. The eyes are large and striking, with a white ring framing them.

The bird’s call is a series of short, high-pitched whistles that are hard to hear unless you are very close.

Similar Species

The Black-breasted Buttonquail’s plumage pattern is unique, making it easier to identify in the field. However, some species share some similarities that could cause confusion.

The Chestnut-backed Buttonquail is one of them. This bird has a similar size and shape, and its plumage coloration is almost identical to that of the female Black-breasted Buttonquail.

However, the Chestnut-backed Buttonquail lacks the white eye-ring found in the Black-breasted Buttonquail.

Plumages

The Black-breasted Buttonquail has two plumages, the breeding and non-breeding plumages. During breeding, the male’s plumage changes dramatically to reveal brighter, bolder colors.

This is when the males’ breast turns entirely black, contrasting with its cinnamon-colored crown. However, during the non-breeding period, the males’ breeding plumage fades, and the colors become less distinct.

The females’ plumage remains almost the same in both breeding and non-breeding periods, with the only notable difference being in the intensity of the colors.

Molts

The Black-breasted Buttonquail undergoes two molts annually, the breeding and non-breeding molts, which correspond to their respective plumages. The breeding molt occurs in May-June, and the non-breeding molt occurs from December to January.

This is the time when old feathers are replaced by new ones, giving the bird a fresh look. In conclusion, the Black-breasted Buttonquail is a fascinating bird species that is not only difficult to spot but also has a unique plumage pattern.

We hope this article has helped you identify and understand this bird better. If you happen to see one in the wild, you can marvel at its small size, striking white eye-ring, and its distinctive black and white barring on its wings.

The Black-breasted Buttonquail, scientifically known as Turnix melanogaster, is a small bird endemic to Australia. This ground-dwelling bird species belongs to a family of quails, and its systematics history, geographic variation, subspecies, related species, and historical changes to the distribution is what we will be exploring in this article.

Systematics History

The Black-breasted Buttonquail was first described in 1823 by the English ornithologist William John Swainson. Later on, in the 20th century, this bird’s systematics were studied by Alexander Wetmore and Charles Vaurie, who concluded that there were no major differences to justify separate groups.

Currently, this bird species is one of the two species within the Turnix genus in Australia.

Geographic Variation

The Black-breasted Buttonquail is found across the Australian continent, from the tropical areas of northern Queensland to the temperate southern areas. This bird species is known to occupy two subspecies, which display some variation in the intensity of their plumage colors and breast patterns.

The two subspecies are as follows:

1. Turnix melanogaster melanogaster: This subspecies is found in northern and eastern Australia, including the Cape York Peninsula and the northeastern coast.

The male Black-breasted Buttonquail from this subspecies has a black breast and cinnamon-colored crown, while the females have a rusty-colored crown and olive-brown plumage. 2.

Turnix melanogaster australis: This subspecies is distributed across southern and southwestern Australia. The males from this subspecies have a richer cinnamon-colored crown, and their breasts are less black, while the females are slightly larger and heavier than the T.m. melanogaster.

Subspecies

The Turnix melanogaster melanogaster and Turnix melanogaster australis are the only two subspecies of the Black-breasted Buttonquail currently recognized. However, in 1910, British ornithologist Walter Rothschild described another subspecies, the Turnix melanogaster clifoni.

This subspecies was basing on the fact that it only existed in the Chambezi forest, Tanzania, although it was later discovered that it was a completely different species, the Black-rumped Buttonquail.

Related Species

The Black-breasted Buttonquail belongs to the Turnicidae family, which includes species that are native to Africa and the Indian subcontinent. The Family Turnicidae is a monophyletic group, and the closest living relatives to the Black-breasted Buttonquail are the Painted Buttonquail (T.

varia) and the Barred Buttonquail (T. suscitator).

The genus Turnix is unique among the order of Galliformes, which constitutes game birds, in the sense that they share some features with rails and cranes than they do with quails.

Historical Changes to Distribution

Historically, the Black-breasted Buttonquail populated a larger area than its current range. The bird species is known to have existed on the island of Tasmania in the past, but its presence is no longer felt there.

The primary reason behind the decline in the Black-breasted Buttonquail distribution is habitat loss due to land-use changes, particularly the development of urban and agricultural areas. Moreover, the bird has also suffered from predation by introduced mammals like foxes, cats, and rats.

In conclusion, the Black-breasted Buttonquail is a unique bird species that has survived for centuries despite the various challenges it is facing. Its systematics history, geographic variation, subspecies, related species, and historical changes to distribution provide insight into the evolution of this bird species and the challenges it faces.

Studying this bird helps us understand how human actions affect wildlife and how we can better protect them and their natural habitat. The Black-breasted Buttonquail (Turnix melanogaster) is a ground-dwelling bird that is endemic to the Australian continent.

Additionally, this bird prefers areas with dense ground-level vegetation, which it uses to conceal itself and protect itself from predators. The Black-breasted Buttonquail is not known to be migratory, and it generally lives in one area throughout the year.

Movements and Migration

The Black-breasted Buttonquail is non-migratory, and it is predominantly a sedentary species. However, it is known to make seasonal movements within its habitats to find adequate food and water supply.

During the wet season, these birds shift to areas with a higher density of green vegetation and water. Conversely, during the dry season, they move to locations with deeper soil to find enough food and water.

This bird species has a home range of about 2 to 5 hectares, and during breeding, the home ranges of both males and females overlap. These movements are also influenced by geological factors like wildfires that can temporarily limit the habitat of this bird species.

In case of habitat loss, the birds shift to nearby undisturbed areas but prefer not to travel too far outside their home ranges. The Black-breasted Buttonquail has a distinctive behavior of mostly walking instead of flying.

This is partly due to their physique as they are too small and heavy-bodied for extended periods of flight. Migration is not typical for this bird species, mainly because they are already found in tropical regions, and there is limited variation in temperature between summer and winter.

With no need to travel long distances for food or to flee from harsh climatic conditions, Black-breasted Buttonquails usually remain in their preferred habitats virtually throughout the year. However, changes in weather patterns, such as extreme drought or significant weather fluctuations, may force the birds to migrate to other areas.

In such cases, only a temporary migration occurs, where they move to find more favorable climatic conditions. The seasonal movements of the Black-breasted Buttonquail are typically influenced by the availability of food and water resources throughout the year.

As such, prolonged periods of drought or excessive rainfall may lead to the birds’ local movements in search of abundant food and water. In conclusion, the Black-breasted Buttonquail is a non-migratory bird that lives in a variety of habitats throughout Australia and has seasonal movements to find adequate food and water supply.

As a ground-dwelling bird, walking is the primary mode of transportation for the Black-breasted Buttonquail, mainly due to its heavy body. Understanding the movements and migration patterns of this bird species is essential in developing long-term strategies for habitat preservation and conservation.

The Black-breasted Buttonquail, also known as Turnix melanogaster, is a ground-dwelling bird species that is endemic to Australia. This bird species has unique characteristics that enable it to survive and thrive in the various ecosystems it inhabits.

In this article, we will delve deeper into two of these features, diet and foraging, and sounds and vocal behavior.
