Aims Dujiangyan is located in a regional hotspot of biodiversity, which has significantly high avian diversity. However, a comprehensive list of bird species is still lacking there. Therefore, we conducted fixed-line transects bird surveys in Dujiangyan from May 2016 to August 2019 to map the avian diversity of the region.

Methods Comprehensive surveys have been done to evaluate diversity of breeding birds by using the fixed line transects method. A total of 10 survey lines were set up inside and outside protected areas in the Dujiangyan, covering a wide range of diverse habitats at different altitudes. Based on historical document catalogs, infrared camera data, and data from the China Bird Report (, an updated list of the Dujiangyan was created in this study.

Results Combined with historical documents, a total of 311 species of birds were recorded in Dujiangyan. The birds belong to 17 orders, 61 families which including 184 residents (59.2%), 68 summer visitors (21.9%), 35 winter visitors (11.3%), and 24 passage migrants (7.7%). Breeding birds are 252 species (81.0%) and passerine birds are 212 (68.2%) species. Fifteen species (4.8%) are endemic to China and 9 Class-I (2.9%) and 50 Class-II (16.1%) nationally protected birds were recorded in this region, respectively. Most of the birds were found in the shrubs, evergreen and deciduous broad-leaved mixed forest habitats, while the evergreen coniferous forest and bamboo forest had fewer. The elevational richness of birds in Dujiangyan displayed a bell-shaped pattern with the highest species richness occurred at mid-elevations (1,580-1,890 m) and the lowest species richness at high elevations (1,890-2,200 m).

Conclusion Dujiangyan is a global biodiversity hotspot, as well as a famous national tourism destination, in order to maintain the high diversity of birds in this area, we should reduce the area of monoculture commercial forests and the control human disturbance from tourism, as well as keep monitoring, studying, and conserving the diversity of birds into the future.
