I N TH E W I L D SEAR CHING FOR A SIGN Work continues to track both the released and wild pygmy hogs across the tall grasslands of the Himalayan foothills. Over the last year, the team have been monitoring populations of this threatened species in four protected areas covering their entire range. The field team surveyed each region looking for signs of pygmy hogs and other native species such as the hispid hare and hog deer. The presence of nests and droppings are the leading indicators that an area is being used by the hogs. The surveys covered a total area of 36km2, with almost 240 hours spent searching. Based on the results of these surveys, 50 camera traps were installed in three major grasslands in Manas National Park. The cameras managed to capture pygmy hogs in three different locations, as well as many other native species that rely on this unique grassland.
CAUGHT IN THE ACT
A FINCH SAFETY NET
One of the main threats to the endangered white-breasted thrasher in Saint Lucia is predators taking young birds from the nest. Camera traps have been installed to monitor nest activity to identify which species pose the most severe risk to the chicks and eggs. In particular, whether they are natural endemic predators such as the Fer-de-Lance or introduced alien species, such as the small Indian mongoose. This information will help the team to develop a predator control programme that will hopefully increase the fledgling success rate.
An island-wide eradication of invasive predators is due to begin on Floreana in the Galápagos Islands in 2020. Five species of Darwin’s finches have been identified as being at potential risk during this period, including the medium tree finch which is found only on Floreana. To guarantee the safety of these birds, individuals of each species will be held in captivity throughout the eradication and monitored post-release. Captive trials have identified the needs of the finches to establish best practice guidelines to ensure their survival in captivity. The first step will be to improve the holding facilities by extending the aviary. This will allow birds to be kept in appropriate densities that guarantee good health and welfare.
