Named by Lionel Walter Rothschild in 1892, the Laysan Duck is named after Laysan island, one of the Northwestern Hawaiian Islands. Environmental catastrophes such as drought, severe storms, and tsunamis may decimate populations. [Johnson and Sorenson 1999].

[Dill & Bryan 1912] RecoveryAfter many rabbits starved and the remaining ones were eradicated by biologists in 1923, the ducks began to recover, increasing to a population of about 500 individuals by the 1950s. http://www.birdlife.org on 10/12/2020. 2011); however, the species appears to have suffered a c.50% decline in its adult population on Laysan following the winter storms and tsunami of early 2011 (J. R. Walters in litt. Management strategies have been initiated on Midway Atoll that should reduce the future impact of avian botulism outbreaks, including: annual flooding of the concrete-lined catchment during the summer months; drainage and cleaning of the catchment in the autumn or winter months to remove accumulated debris and seabird remains; vegetation removal around wetlands to allow carcass detection; weekly population monitoring that includes carcass removal and searches for sick birds; wetland carcass searches daily during the summer months; and use of heavy equipment and portable pumps each year to improve water quality (Work et al. 2011). It is located 930 miles (1,496 km) northwest of Honolulu. The Midway population was created by translocations from Laysan in 2004 and 2005. Most adult birds use dense cover and hide in the terrestrial vegetation during the day. "Auk" 116(3): 792–805. Duckling survival is low on both sites. Reintroduced birds on Midway Atoll appear to breed successfully at an earlier age and produce larger clutches than birds on Laysan, probably owing to more food and a low population density. After many rabbits starved and the remaining ones were eradicated by biologists in 1923, the ducks began to recover, increasing to a population of about 500 individuals by the 1950s.

By 1860, the ducks disappeared from all but Laysan Island (the duck’s namesake), most likely due to predation by introduced rats. It once lived throughout the Hawaiian Archipelago but vanished from the main Hawaiian Islands with the arrival of rats around 800 years ago. In 2004 and 2005, … Pair formation begins in fall, and nest building begins in spring. Fish and Wildlife Service to restore a second population of ducks in the wild. Historic declines on Laysan leading to the near-extinction of the species are attributed to introduced rabbits and, more recently, the parasitic nematode Echinuria uncinata, coupled with drought (Work et al.

On Midway, individuals in their first year and produce an average clutch of seven eggs, whereas birds on Laysan nest in their second year, producing an average of 3.3 eggs (Walters and Reynolds 2013). Conservation efforts focus on maintaining the Laysan Duck population on Laysan Island and Midway Atoll and to establish … This plan includes wild translocation and the establishment of a successful captive or semi-captive breeding program using wild source eggs for reintroductions to the Main Hawaiian Islands. Prior to the tsunami, two winter storms struck in January and February, bringing high wind and extensive flooding. 2010), and an outbreak of this disease has occurred every year since (M.

Although the non-migratory Laysan Duck can fly, it does not disperse between islands.The Laysan Duck found refuge through most of the nineteenth century on rat-free Laysan Island, surviving within the smallest geographic range of any duck species worldwide (415 hectares, or less than four square miles). For example, Laysan Ducks are more likely to freeze their movement rather than flush or fly when startled— a strategy well suited for cryptic defense against Hawaii’s native flying predators, but ineffective against ground predators. If basic criteria of the recovery plan are met, the Laysan Duck could be down-listed from endangered to threatened by 2019.Notes References * (1999): Phylogeny and biogeography of dabbling ducks (genus Anas): a comparison of molecular and morphological evidence. To achieve this goal, biologists plan to establish at least five populations on a combination of predator-free Northwestern Hawaiian Islands and predator-controlled sites on Main Hawaiian Islands.

The goal of the recovery program is to conserve and recover the species to the extent that it may be down-listed from endangered to threatened in the near future, and ultimately, that the population be healthy enough to no longer require federal protection under the Endangered Species Act. Laysan ducks were extant on Lisianski as late as 1844. Fossil evidence reveals that Laysan Ducks once lived across the entire Hawaiian Island chain, but today survive only on three small, isolated islands. Additionally, the plan calls for achieving gene flow between the wild source populations through long-term inter-island translocations, and island-specific management for each population to reduce threats and improve quality of habitat.

[USFWS 2005] The second “insurance” population of Laysan Ducks on Midway has grown quickly, more than doubling in size within the first two years (USGS 2006c). The decline of the Laysan Duck began 1000-1600 years ago, with the colonization of the Hawaiian Islands by Polynesians and associated non-native mammalian predators. With the Laysan population possibly approaching carrying capacity, 42 individuals were translocated to the two islands of Midway Atoll National Wildlife Refuge in 2004 and 2005; the birds bred successfully in their first year (Reynolds and Klaviter 2006). Human disturbance may impact nesting and brooding, and landing permits to the Laysan Island refuge are granted only for official or scientific purposes. Portland, OR.

This suggests that the abundant habitat and food available on Midway has stimulated greater reproductive effort in the ducks, which contributes optimism for the success of this re-introduced population. The emphasis of the recovery plan is the distribution of additional viable populations in the Laysan Duck’s historical and prehistorical range. 2011). The spread of parasites such as the nematode "Echinuria uncinata" could be extremely pathogenic, as well as the introduction of disease by migratory waterfowl along the Pacific Flyway (such as avian influenza, avian malaria, cholera, botulism and duck plague). The Laysan duck population was recorded at 11 birds in 1911; their numbers climbed quickly after the rabbits were eradicated from Laysan in 1923.

Caleb Freeland FWE 360 10/23/20 Laysan Duck The Laysan duck (Anas laysanensis), also known as the Laysan teal, is a dabbling duck that is native to the Hawaiian Islands. Iridescent speculum appears teal green, or blue. However, population bottlenecks occurred, such as the severe 1993 El Niño drought and food shortage, which reduced the number of ducks to about 100. The newly established population on Midway lays larger clutches. Other threats faced by the species include accelerated filling of the interior lake and freshwater seeps due to alien wetland plant species, and erosion of dunes from storm impacts (M.

Population estimates for the species on Laysan Island indicate that it had been increasing between 1994 and 2010, although apparently the trend has not been consistent (Seavy et al. The cause of its extirpation from the majority of the Hawaiian islands is unknown, but is presumed to have been induced by Polynesian colonizers and the mammalian predators, such as rats, that they brought with them. The species is consequently precautionarily maintained as Critically Endangered, since although it now occurs at two locations and was recently translocated to a third island, population fluctuations have continued within the past five years. and Main Hawaiian Islands (MHI) prior to the arrival of Polynesians and occurred on the islands of Hawai‘ i, Moloka‘i, O‘ahu, Maui, and Kaua‘i.
