Since its birth, citizen science has gradually become a scientific activity that the whole society participates in. In bird research, research results based on citizen science data are increasing, but there is no comprehensive and systematic analysis of the status of research in this field. This paper uses CiteSpace software to visually analyze the application status of citizen Science data in bird studies by means of keyword timeline evolution map, keyword clustering map and hot spot emergence analysis, based on 925 literatures from 1984 to August 2024 in the core database of Web of Science. The results show that: (1) The development of the discipline has gone through three stages, and the number of published papers has successively gone through a trend of constant increase, exponential increase and fluctuation decline. (2) At present, foreign scientific research institutions are relatively active in this field, and the research content of these institutions has undergone a transformation process from the descriptive research of basic data to the upgrading of algorithms, model development, and then to the expansion of data application and the introduction of new technologies. (3) The research topic clustering results show that this field can be divided into 20 clusters, such as population dynamics, species distribution, agricultural environment policy and bird breeding survey, and four general directions of bird population research, external impact research, bird medical research and bird physiology research. "Citizen science", "range shift", "biodiversity" and "climate impact" will be future research hotspots in this field.
