Using Samoan traditional ecological knowledge to identify calls of the critically endangered endemic tooth-billed pigeon (Didunculus strigirostris)

The tooth-billed pigeon (Didunculus strigirostris) is an endemic and highly cryptic bird of the rainforest canopy of Samoa. According to the recently released Tooth-billed Pigeon Recovery Plan (2020–2029), one of the greatest obstacles to conservation efforts is the inability of ornithologists to reliably separate its advertising coo call from that of the common and sympatric Pacific imperial pigeon (Ducula pacifica).

IMPACTS OF PLASTIC POLLUTION ON FRESHWATER AQUATIC, TERRESTRIAL AND AVIAN MIGRATORY SPECIES IN THE ASIA AND PACIFIC REGION

This report is the result of a collaboration between the Convention on Migratory Species and the UN Environment Programme as part of the CounterMEASURE II plastic pollution programme, generously funded by the Government of Japan, to assess the impact of plastic pollution in the Asia-Pacific region. It was prepared for the CMS Secretariat by the National Oceanography Centre, UK. This report is an important addition to knowledge on the threat of plastic pollution on CMS-listed species in terrestrial and freshwater ecosystems in the region.

Despite major conservation efforts, populations of New Zealand's iconic kiwi are more vulnerable than people realise

Like many endangered species, Aotearoa’s flightless and nocturnal kiwi survive only in small, fragmented and isolated populations. This leads to inbreeding and, eventually, inbreeding depression — reduced survival and fertility of offspring.
