This study assessed the distribution of suitable habitats and ecological drivers for 47 waterbird species in eastern and southern China (south of the 800 mm isohyet), revealing a clear coastal‐to‐inland gradient, with NDVI and DEM identified as key environmental variables. Different ecological groups exhibited distinct habitat preferences.

Nest-site habitat partitioning by Arctic, Common, and Roseate terns
When closely related species that share aspects of their habitat niches nest in sympatry, selection is expected to favor species-specific differences in nest-site selection that allow birds to partition habitat. We tested habitat-partitioning theory in a

Patterns in tern trophic diversity in a region experiencing rapid climate change
Foraging plasticity provides a mechanism for long‐lived species to adapt to rapidly changing environments. When shifts in food availability occur, individual variation in plasticity can lead to an increase in within‐species trophic diversity.
