01
Species Richness
Breeding Bird Survey Taiwan vs. eBird
Comparing species richness at standardized duration between the two largest avian datasets in Taiwan.
02
Benchmarking Bird Community
Neotropical Birds
We analyzed long-term monitored sites to assess the change in bird communities in Central and South America.
Species Richness
It is common to see studies overlook the importance of comparing biodiversity measurements at the same sampling effort, which results in biased data interpretation.
In this project, we compared species richness from the Breeding Bird Survey (BBS) and eBird Taiwan datasets at a 60-minute duration. Plus, we applied a species richness estimator (Chao1) on both datasets to calibrate imperfect detection and variable sampling efforts.
We found that BBS outperforms eBird in species richness. Even though we calibrated species richness in eBird, BBS still had higher species richness. We speculate observers in the BBS program possess skilled identification, aiming to detect more species. In addition, BBS sites are distributed to cover diverse habitats within a 2×2 km area, which may contribute to a higher diversity of birds. Our insight highlights the importance of incorporating variable sampling effort when comparing different datasets.

Big Bird Plots
We analyzed more than 500 research articles focused on bird communities in Central and South America. Birds in Panama show higher abundance and species richness than plots from Amazonia and Guianan plateau. We propose future continuation collaboration with ForestGEO long-term monitoring program.
