Abstract

We summarized 13.5 years (2011- 2024) of Common Yellowthroat (Geothlypis trichas) captures: 758 banded and 109 recaptured (14.4%), with spring - fall tick screening from 2011 to 2020 at the Chippewa Run banding station, Empire, Michigan. Age and sex composition was consistent between years, and capture phenology followed a repeatable sequence (After Hatching Year [AHY] males most common in spring, AHY females most common through summer, and Hatching Year [HY] individuals most common in late summer to fall). AHY males were largest, exhibiting bimodal distributions in both mass and wing chord, with fall individuals showing longer wings than those captured during spring and summer. Oldest recaptured individuals were at minimum 4 yr 11 mo. Tick prevalence was 7.3% (involving 43 Ixodes scapularis and five Haemaphysalis leporispalustris) with seven reinfestations.
