Abstract:
We used audiovisual point counts on eight subplots per plot to record birds in the warm dry season (December to March) and in the cold dry season (July to October). We established circles with a 20-m radius in densely vegetated habitats (savanna and all forest habitats) and 35.5 m × 35.5 m squares at Helichrysum plots, covering the same sampling area in all habitat types. All birds heard or seen in one subplot were counted for 10 min and identified to species level. Point counts started 15 min before sunrise and were completed before 09:00. All 480 point counts (30 plots × 8 subplots × 2 seasons) were conducted by the same observer (Ferger S. W.) to reduce inter-observer variability. This dataset contains also bird individuals that were recorded higher than maximum canopy height at the respective subplots in the respective season (see publication for details).

Comment:
Point count data of birds for all 60 plots plus 4 sun-coffee-plantations. Be aware that this dataset contains also bird individuals that were recorded higher than maximum canopy height at the respective subplots in the respective season. If you do not know what this means in terms of suitability of this dataset for your intended analyses, you should definitively contact the data owner and maybe consider the alternative dataset "SP6 PointCountsBirds_BirdsBelowMaxCanopyHeightOnly".
