Population size. This is one of the fundamental attributes used to assess the status of a flyway population. The sizes of waterbird populations are constantly changing, yet population size estimates are usually only measured periodically (updates once in every 3-12 years). Therefore, it is important to use metrics that provide the best characterisation of the population size until the next assessment. If the population is fluctuating, the best characterisation of the ‘current’ population size is to present the five-year mean of the population estimate +/- the 95% confidence intervals (if a sufficient number of annual surveys have taken place). In the case of populations that are clearly increasing or decreasing, the five-year mean would be a biased characterisation of the ‘current’ population size, therefore the five-year maximum or minimum is used, respectively. When the population estimate is not based on yearly counts, but only minimum and maximum estimates are available, the geometric mean of these two values is used because it provides a more robust estimate of the population size than the arithmetic mean.
Population size. With a population estimate of a few 1 000 in the 1985 population estimate for Tanzania, the country currently has less than 2 000 individuals and no real evidence to suggest that there are more than a 1 000. They are widespread across the country, with two non-breeding concentrations on the North West slopes of Mount Kilimanjaro and in the caldera of Ngorogoro Crater. Breeding has been recorded from the northern parts of the country (including Serengeti National Park, Tarangire National Park, Arusha National Park, Lake Manyara National Park and Katavi National Park) and in Usangu, which has been incorporated into Ruaha National Park.
Population size. In 1985, it was estimated that Rwanda was home to more than 1 000 Grey Crowned Cranes. The population is currently estimated to be between 300 and 500 individuals, distributed between the main wetland systems in the country. Rugezi Xxxxx is the primary site for Grey Crowned Cranes in the country, but they are also found in Akagera National Park, Kamiranzovu Wetland inside Nyungwe National Park, Nyabarongo Wetland and Akanyura Wetland. The latter two, although Important Bird Areas, have no protected area status or protection. Population trend Grey Crowned Cranes are declining in Rwanda largely due to their removal from the wild for the domestic pet trade and habitat loss primarily to agriculture. The “Peat to Power” plans for Rwanda, whereby peatlands will be removed for power generation will no doubt escalate this decline further.

Population size. The South African population of Grey Crowned Cranes is the only increasing population across their range. They have increased from a few 1 000 birds in 1985 to an estimated 6 500 in 2012. The population is found along the eastern highland grasslands of the country, with the primary population found on private land in the southern Drakensberg region, traversing the northern parts of the Eastern Cape Province and the southern reaches of the KwaZulu-Natal Province. Population trend The species is increasing in the country, with an estimated 44% increase between 2001 and 2012. However, threats to the species include habitat loss, the illegal removal of birds for the captive trade market, collisions on overhead wires, electrocutions on electrical infrastructure and poisoning.
Population size. In 1985, the population in Zambia was estimated at less than 1 000 individuals. Recent estimates put the population at more than 2 000 individuals. Key sites for cranes in Zambia include Liuwa Plains National Park and the entire Barotse Floodplain in western Zambia, Lochinvar and Blue Lagoon National Parks on the Kafue Flats, Kafue National Park, South Luangwa National Park and Tondwa Pans. Population trends The Zambian population, although potentially in decline in some areas, is likely stable to increasing country wide. This is largely due to the fact that the key areas for Grey Crowned Cranes in the country are National Parks and are afforded some degree of protection. That said, the encroachment of the alien invasive Mimosa pigra on the Kafue Flats, uncontrolled fires and human disturbance all pose a serious threat to the species.

Population size. The annual breeding population is estimated at 5 150 pairs, indicating a global population of 17 000 adults, or 33 000 individuals. The species is essentially restricted to Antipodes Island, although about six pairs also breed on Xxxxxxxx Island each year. Status
Population size. The annual breeding population of Xxxxxx'x Albatrosses is estimated at about 6 200 pairs breeding each year, perhaps 10 000 pairs in total, or 40 000 individuals. This species is restricted to breeding on three islands within the New Zealand sub-antarctic Auckland Island group: Xxxxx Island (5 800 pairs; 95% population), Disappointment Island (250 pairs; 4% population) and Auckland Island (65 pairs; 1% population).
Population size. The most abundant of the southern albatross species. Current population is approximately 682 000 breeding pairs, perhaps three million birds in total. This species is most numerous at the Falkland Islands (Islas Malvinas) (80% of global populations), particularly at Steeple Xxxxx Island where about 250 000 pairs breed annually. The smallest Black-browed Albatross populations occur on the Australian and New Zealand sub-antarctic islands. Status Black-browed Albatrosses are the most widely distributed of all albatross species and their population status varies with respect to location of colony. The status of many of the smaller populations is not known, although current studies in both the Australian and New Zealand sectors should partially redress this situation. Whilst some colonies have shown signs of increases, low rates of adult survival and juvenile recruitment at the two most intensively studied populations (Bird Island and Kerguelen Island) are causing the populations to decline.
