On 13 June 2021, a video was recorded showing an adult female Asian Koel Eudynamys scolopaceus removing three Elliot's Laughingthrush Trochalopteron elliotii nestlings from a nest in a thicket on the banks of Liqiu River in Xinduqiao Town, Kangding, Sichuan, Southwestern China. This is the first record of an Asian Koel removing nestlings from a potential host's nest. Of the various brood parasitism hypotheses, this behavior is most consistent with the farming hypothesis, further suggesting that farming behavior may be a common strategy used by obligate brood parasites.

We used radio telemetry to provide the first information concerning home range size of Hainan Partridge Arborophila ardens, a vulnerable species endemic to Hainan Island, China, in both a fragmented and a continuous natural rainforest. Both the monthly and daily home range sizes of the population in the fragmented rainforest were significantly larger than those in the continuous rainforest, with no difference between males and females. Fragmentation reduced habitat quality and thus may have forced the partridges to forage over a wider range, which may threaten their survival.
