While many species are affected by trafficking in their products, some take centre stage, including elephants, rhinos, pangolins and helmeted hornbills, and we report an open trade that continued in these items in eastern Myanmar between 2015 and 2020. We surveyed Myanmar’s border towns of Tachilek and Mong La, recording volumes, prices, origins and trade routes. We observed c. 16 500 ivory items, 8 helmeted hornbill casques and 264 beads, over 100 African rhino horn items and over 250 pangolins (mainly skins and scales). In 2020, asking prices in Mong La for rhino horn tips were US$10 770, rhino horn bracelets US$5385, helmeted hornbill casques US$2424 and big ivory bangles c. US$800, with prices being stable overall since 2017. We estimate the combined monetary values at US$0.25–0.30 million for Tachilek and US$0.75–2.00 million for Mong La. Mong La’s market today far surpasses Tachilek’s, being on the border of mainland China. Mobile phones and online trading allow customers to order items without bothering to cross the borders. Commitment to address the illegal wildlife trade across Myanmar’s borders requires a greater degree of cooperation and coordination amongst the relevant authorities in Myanmar, China and Thailand.

Many hornbill species in Thailand are categorized as Endangered or Critically Endangered on the IUCN Red List. The objectives of this research were to predict hornbill distributions in Thailand and to assess the national conservation status of the species using extent of occurrence. We employed maximum entropy modelling, using 10 environmental variables that were believed to directly or indirectly influence hornbill distributions across Thailand, to predict the habitats potentially suitable for 10 of the country's 13 hornbill species. Data on the presence of hornbills were gathered from the Thailand Hornbill Project and additional field surveys in protected area complexes during 2004–2006. The results indicated that patch size is the most important factor affecting distribution, followed by latitude, ecoregion and distance to villages. All hornbill species were predicted to occur primarily in intact protected area complexes. The total extent of all hornbill habitats covers 9.3% of the country's land area. Seven of the 10 modelled species are at risk and the current distribution pattern is expected to reflect stochastic extinctions because of small population size. We recommend that the conservation status of Austen's brown hornbill Anorrhinus austeni and Tickell's brown hornbill Anorrhinus tickelli should be changed from Vulnerable to Endangered. The model identified five protected area complexes as hornbill hotspots in Thailand. These findings will help guide conservation management.
