Overall Connectivity for Willow Tit

Most movements show short-range dispersal (<500 km; usually <100 km). Most recovery data from N and E European ringing regions, specifically from the circum-Baltic region and Russia. Random dispersal from ringing area. Exceptional long-distance recoveries, e.g. a bird from Estonia recovered in Moldova, or a bird from Belgium recoveries in Spain.

Recoveries by Condition for Willow Tit

Overall, 93% of recoveries associated to ringing. Before 1960, however, ca. 20% of recoveries were due to birds found dead, sick or wounded; from 1991 to present, this proportion is less than 1%. During the 1961-1990 time period, recoveries of birds recaptured alive already reached 94%, a proportion maintained from 1991 to present.

Annual Movements for Willow Tit

Higher number of recoveries in Sep-Oct, mostly juvenile individuals during post-fledging dispersal, that join non-kin wintering flocks (Hogstad & Slagsvold 2018). Otherwise shorter distance movements almost all year long, no specific yearly pattern as species is mostly resident.
