Linking wetland inundation and habitat selection to Blue-winged teal survival throughout the full annual cycle
January 2023 - June 2025
- Delta Waterfowl
Compared with other dabbling ducks, blue-winged teal (Spatula discors, BWTE) migrate earlier in autumn, migrate later in spring, and winter at more southern latitudes with a broader distribution. Thus, the extent to which management decisions, particularly wetland inundation that allow other dabbling species to access food resources, benefit BWTE remains unclear. We propose to use data from BWTE marked with GPS-GSM transmitters and satellite imagery, to better understand the role of environmental variability (e.g., water availability) and land ownership on BWTE resource selection, movement, and survival during the annual cycle.
