Ecological and anthropogenic drivers of waterfowl productivity are synchronous across species, space, and time

We used hierarchical random-effects models to examine interspecific and spatial variation in annual productivity in six migratory ducks (i.e., American wigeon [Mareca americana], blue-winged teal [Spatula discors], gadwall [Mareca strepera], green-winged teal [Anas crecca], mallard [Anas platyrhynchos] and northern pintail [Anas acuta]) across six distinct ecostrata in the Prairie Pothole Region of North America (Alberta parkland, Alberta prairie, Saskatchewan parkland, Saskatchewan prairie, Manitoba parkland, US prairie). We tested whether breeding habitat conditions (seasonal pond counts, agricultural intensification, and grassland acreage) or cross-seasonal effects (indexed by flooded rice acreage in primary wintering areas) better explained variation in the proportion of juveniles captured during late summer banding. This submission comprises model code and data of banded birds by species, breeding population survey by species, proportion of ecostratum in conservation tillage (a proxy for agriculutral intensification), proportion of ecostratum in grassland, mean winter precipitation for Pacific Coast and Gulf Coast, total hectares of rice planted in the US, as well as hectares of flooded rice in the Pacific Coast and Gulf Coast.
