Wren

Model Family : Resident detectability

Summary

Wren

Resident with summer detectability collapse

Wren is classified as resident with summer detectability collapse. The fitted resident detectability target peaks around April and reaches its lowest point around August. The model indicates weak baseline presence, strong spring carry-over, strong pre-summer retention, moderate summer suppression, and moderate summer decay acceleration.
