Descripción de la metodología paso a paso:
- From January 2019 to December 2019, monthly bird surveys were conducted at each of the 12 university campuses using line transect methods. Within each campus, two fixed survey transects were established to cover a variety of habitat types including water bodies, grasslands, woodlands, educational areas, and sports fields. The length of these transects ranged from 0.5km to 2km, depending on the size of the campus, with the aim of covering the entire campus as comprehensively as possible. On days with clear weather conditions, no rain, snow, or strong winds, surveys were carried out between 07:00 and 10:00 in the morning and between 16:00 and 19:00 in the afternoon. Surveyors walked along the transects at a speed of approximately 3km per hour. Using 10x40 binoculars, they observed and recorded bird species within 50 meters on both sides of each transect using direct identification and call-count methods. In the event of flying birds, only those flying in the opposite direction of the surveyors were counted, while birds flying from behind were not counted. During the surveys, bird species and their quantities were recorded along each transect. When encountering large flocks of birds, group counting methods were used.
