Information about the Bird Red-breasted Goose
The red-breasted goose (Branta ruficollis) is a brightly marked species of goose in the genus Branta from Eurasia. It is sometimes separated in Rufibrenta but appears close enough to the brant goose (Branta bernicla) to make this unnecessary, despite its distinct appearance. It is currently classified as vulnerable by the IUCN. Branta is a Latinised form of Old Norse Brandgs, "burnt (black) goose and ruficollis is from the Latin rufus "red" and collis "necked".
All the species of the Branta genus are distinguished by their dark sooty colour, relieved by white, and as a distinction from the grey geese of the genus Anser. Among the species from these two genera, the red-breasted goose is the smallest at 53-56cm (21-22in) in length. This brightly marked species is unmistakable, but can be surprisingly difficult to find amongst brent geese. At long distances, the red of the breast tends to look dark.
The red-breasted goose breeds in Arctic Siberia, mainly on the Taymyr Peninsula, with smaller populations in the Gydan and Yamal peninsulas. Most winter along the northwestern shores of the Black Sea in Bulgaria, Romania and Ukraine (occasionally moving further southwest to Greece), but some winter in Azerbaijan. It is a rare vagrant to Great Britain and other western European areas, where it is sometimes found with flocks of Brent or barnacle geese. However, since it is common in captive wildfowl collections, escapees outside its usual range are fairly frequent. While incubating, the red-breasted goose stays within a 1.5km range of its nest. Male red-breasted goose tend to guard the nest of their young from a distance while the females generally hide on the nest. The main predator for red-breasted geese eggs and goslings is the Taimyr Gull which have access to nests located on river islands.
They traditionally wintered in Kirov Bay in the Caspian Sea, but in the 1960s the area became unsuitable for the geese due to the agricultural change. Vineyards and cotton replaced the cereal crops used by the wintering geese. However, catastrophic population decline was avoided because they were able to alter their migration strategy and now winters in suitable habitats in Bulgaria and the Dobrogea region of Eastern Romania.
In the late Pleistocene the species' range expanded southward to Bulgaria
Calls of red-breasted goose - ki-kui or ki-yik, shrill and staccato.
The red-breasted goose often nests close to nests of birds of prey, such as snowy owls, peregrine falcons and rough-legged buzzards, which helps to protect this small goose from mammalian predators such as the Arctic fox. The closer the nest to the eyrie, the safer the goose is from predation. Based on the size and how timid the geese are, they rely on the eagles for defense. It's extremely unusual for the eagles to attack, but is still possible. Additionally, the larger the colony the safer it is. This in turn positively influences the survival and reproductive success of the red-breasted goose. Aside from nesting close to birds of prey, red-breasted geese nest on islands on rivers which also protects them from land-based predators. However, there is evidence that the red-breasted goose will prefer to nest near birds of prey over the choice of a river island. In contrast to the birds of prey that offer the red-breasted goose protection from predators, which choose to place their nests in the open cliff side, this goose will create a cryptic nest hidden much better than the birds of prey nests. A typical red-breasted goose colony is around 4 pairs depending on nest location, food abundance, and bird of prey density.
While wintering, the red-breasted goose feeds on grasses, leaves and seeds. Since owl and buzzard populations fluctuate every few years, depending on lemming abundance, the only consistent protection from predators are river islands and the peregrine falcon.
In Autumn of 1997 the population was estimated to be around 88,000 individuals. In the Winter these numbers can shrink to around 70,000. The red-breasted goose is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies. The red-breasted goose is legally protected in many states, however hunting is still continued. The AEWA is monitoring the species and providing up to date information on the status of the species, its habitat, migrations, ecology, and conservation needs. It was considered a Vulnerable species by the IUCN. Over 80% of the population roost during the winter at just five sites, with nearby feeding areas threatened by changes in land use. In addition, there has been a strong decline in numbers in the last decades. However, it is possible that this decline may have been exaggerated, as it is possible that some birds may winter at unknown sites. The species' winter distribution has already changed significantly since the 1960s when much of the population occurred along the western coast of the Caspian Sea, in Iran, and in Iraq. Some birds may now be wintering farther west as indicated by recorded counts of 2,000 birds in Hungary as of the winter of 2014, whereas counts previously only accounted for a few hundred. As it is not clear to what extent the known population fluctuates in this species-as in other Arctic geese-and given the worsening outlook for the species as a whole, the red-breasted goose was uplisted from a species of Least Concern to Endangered status in the 2007 IUCN Red List. In 2015 it was relisted as Vulnerable. There have been attempts to conserve the species, such as in 2005-2008, a Life-funded project in Romania was implemented so that the habitat quality of an important salt water lake used by the species was increased. The Life Programme and AEWA hosted a workshop in February 2009 for the species that aimed to draft a new International Species Action Plan and report the results of the Life project.
In 2011, Ornithologists from the Bulgarian Society for the Protection of Birds (BSPB/BirdLife in Bulgaria) and the Wildfowl & Wetlands Trust enacted a project that would lead to a greater understanding of the red-breasted geese's migration patterns. Six red-breasted geese were branded and given miniature GPS transmitters. The red-breasted geese will now be tracked via satellite. Scientist and conservationists alike hope that learning about the geese's migration patterns will lead to proper conservation and more aggressive policies in the geese's territory. Some prior counts have revealed a more positive discovery, noting an increase in the geese's population. This led to a prediction which states there may be over a fifty percent increase in their population.
In February of 2013, the Bulgarian court had overturned a decision which prohibited an energy wind project from continuing their work in an important winter site for the threatened red-breasted geese. The construction of wind turbines in the area not only threaten the geese by being an obstacle that they fly into. The area they are being constructed in will also deprive red-breasted geese of a critical feeding ground. As of now, an appeal had been sent to court to convince the court otherwise.
