Rufous Hummingbird

In western Washington, Rufous Hummingbirds are common migrants and breeders. They are very rare in the winter—usually adult males are first seen in early March. Females appear in April (Wahl et al. 2005). Erika and I caught this male on 10 March 2021. These authors further report that Rufous Hummingbird populations have been declining in Washington since 1966. The reasons for this decline, both in Washington and elsewhere in the Pacific Northwest, are unclear and require further research (Healy and Calder 2020).
