Coal Tit
Model Family : Resident detectability
Summary
Coal Tit
Resident with summer detectability collapse
Coal Tit is classified as resident with summer detectability collapse. The fitted resident detectability target peaks around May and reaches its lowest point around July. The model indicates weak baseline presence, weak spring carry-over, moderate pre-summer retention, moderate summer suppression, and strong summer decay acceleration.
