Hainan leaf warbler biology
The diet of the Hainan leaf warbler is unknown, but is presumed to mainly comprise small leaf-dwelling insects and their larvae, as in other warblers of the Phylloscopus genus (4). Foraging may occur singly or in pairs, but has been recorded in flocks of up to 30. Mixed-species flocks are also sometimes joined (3).
Fledged young and a nest with nearly full-grown young have been found in late April, and breeding is believed to be over by late May, as no signs of breeding activity or territorialism have been observed at that time (3) (4).
TopHainan leaf warbler range
Known only from seven localities in the mountains of Hainan Island, China (2).

Hainan leaf warbler status
Classified as Vulnerable (VU) on the IUCN Red List 2007 (1).
Hainan leaf warbler threats
The Hainan leaf warbler is considered threatened due to its highly restricted range and the ongoing deforestation on the island (2) (3). Timber extraction, the replacement of forest by rubber plantations, slash-and-burn agriculture and the unrestricted cutting of wood for fuel and other uses has destroyed and fragmented Hainan’s forests, and left much of the remaining forest disturbed and modified (2) (4).
TopHainan leaf warbler conservation
The Hainan leaf warbler has been recorded in Bawangling National Nature Reserve, Jianfengling, Baishuiling, Nanweiling, Wuzhi Shan, and Jiaxi Nature Reserves and Limu Shan Forest Park (a proposed nature reserve). A number of studies on the species have been conducted in recent years, helping to provide crucial information on its distribution and abundance (2).

- Larvae
- Stage in an animal’s lifecycle after it hatches from the egg. Larvae are typically very different in appearance to adults; they are able to feed and move around but usually are unable to reproduce.
- Primary forest
- Forest that has remained undisturbed for a long time and has reached a mature condition.
- Secondary forest
- Forest that has re-grown after a major disturbance, such as fire or timber harvest, but has not yet reached the mature state of primary forest.
