Abstract:

Aim: Chengdu Research Base of Giant Panda Breeding serves as a significant urban park green space and an important habitat for avian species within urban ecosystems and migratory bird flyways. This study aims to provide foundational data and a scientific basis for the conservation of urban ecosystems and avian diversity by understanding the composition of bird species in this area.

Methods: This study comprehensively reviewed the records of bird species diversity in this area since 1993, using data from transect surveys, bird ringing, literature, and citizen science contributions.

Results: A total 262 bird species, representing 16 orders, 56 families, and 154 genera, have been recorded at Chengdu Research Base of Giant Panda Breeding. These species account for 45.4% of the total bird species in Chengdu City (n = 577), placing the base among the top urban green spaces nationwide in terms of avian diversity. Notably, the base has documented three Class I species of state key protected wild birds: Aythya baeri, Clanga clanga, and Emberiza aureola. Additionally, 31 Class II species of state key protected wild birds, including Otus sunia, Accipiter trivirgatus, Emberiza siemsseni, and others have been recorded. Compared to the avian checklist in historical records, the current checklist includes 95 newly recorded bird species, 11 species of which are state key protected wild birds. Aythya baeri was recorded in the Swan Lake of Chengdu Research Base of Giant Panda Breeding.

Conclusions: Chengdu Research Base of Giant Panda Breeding exhibits significant avian diversity. Employing various survey methods can yield a more comprehensive bird species inventory, which is crucial for understanding the basic characteristics of urban ecosystems.
