The trade in Asian songbirds is contributing to declining populations of many species in the wild. The Chinese Hwamei Garrulax canorus is a popular songbird endemic to Asia that is traded both domestically and internationally. The songbird trade in the USA, particularly involving Asian songbirds, has not been well studied. We hypothesised that despite Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) Appendix II regulations, Chinese Hwamei are traded illegally in the USA. We scrutinised the CITES Trade Database, US seizure and confiscation records, publicly available records, and websites to assess the imports and availability of Chinese Hwamei in the USA. Since the species was first listed in CITES Appendix II in 2000, there have been three reports of Chinese Hwamei imports into the USA, one of which included four live birds, compared with approximately 40 records of illegally imported birds. Online advertisements of Chinese Hwamei for sale show that both wild-caught and captive-bred birds are easily available. We believe this indicates that there is both legal and illegal trade of the species in the USA. Based on these findings we concluded that more research into the songbird trade, and specifically songbird trade in the USA, is warranted. We recommend additional assessments of CITES and non-CITES songbird species and encourage additional species protection when illegal trade is occurring. We also recommend that the relevant authorities in the USA better scrutinise the trade in non-native songbirds and take meaningful action against anyone found unlawfully importing and trading in illegally sourced songbirds. Finally, we recommend that the International Union for the Conservation of Nature (IUCN) Red List of Threatened Species includes international trade as a threat to the Chinese Hwamei in order to raise concern and motivate action for this songbird.

The hypersaline Lake Urmia, located in Iran, has undergone a significant reduction in size and is currently facing the risk of desiccation. The decrease in water levels, coupled with elevated salinity levels, has initiated ecological degradation, leading to a substantial decline in the region’s waterbird population. This study employs breakpoint analysis to determine the year when the drought event affecting the lake commenced. Additionally, canonical correspondence analysis (CCA) is utilised to elucidate the interaction between environmental parameters and the waterbird assemblages in Lake Urmia over the period 1970–2018. Our investigation identifies the year 2000 as the initiation of the water crisis in Lake Urmia, synchronously coinciding with the decline in the waterbird populations. This finding highlights a significant connection between the majority of waterbird species and the axes of CCA, intricately linked with water availability within Lake Urmia. This revelation underscores the pivotal role of fluctuations in water levels in shaping the dynamics of the lake’s waterbird assemblages. Furthermore, our observations emphasise the importance of even minor improvements in hydrological conditions of the lake, resulting in substantial positive impacts on waterbird populations.

We report how artificial nests can be utilised at scale in nest site-limited areas of Mongolia to create a managed population of Saker Falcons (Falco cherrug), an “Endangered” species that is harvested for international trade. The provision of 5,000 artificial nests created an average annual saker population of 602 (SE ± 59) breeding pairs, producing an estimated 1,735 (SE ± 272) fledglings per annum over the period 2013–2015. Our regular monitoring enabled us to identify the effects of climate and vegetation on breeding performance. A warm and dry climate prior to breeding was associated with earlier egg-laying dates, while warmer conditions during the breeding season increased fledging success. Greater vegetation biomass in the previous growth season was positively related to breeding density and earlier clutch initiation, which was associated with larger clutch size and larger fledged brood size. Furthermore, using small mammal remains from saker pellets collected at artificial nest sites, we found that higher breeding density, earlier egg laying, larger clutch size, and increased nest survival were associated with areas with a higher proportion of small mammal prey in the diet. Our results provided evidence of the role of temporal and spatial variation in climate and prey availability on breeding performance, demonstrating the requirement for dynamic modelling of variable demographic parameters to be incorporated within an adaptive management framework for the sustainable management of the Saker Falcon.
