Yesterday we recaptured two Ruby-throated Hummingbirds (Archilochus colubris) from previous years here in Costa Rica for the first time. Both of these females were banded last year and returned to the exact same location. They traveled most likely over 4,000 miles round-trip since the last time we saw them. Weighing less than a penny it is incredible what these small tenacious birds can do.
