Tiny tech tracks hummingbirds at urban feeders.

The study, conducted September 2016 to March 2018, recorded about 65,500 visits to seven feeding stations across three California sites. These included the UC Davis Arboretum Nursery, a private home in Winters and The Gottlieb Native Garden in Beverly Hills. More than 60 percent of the tagged birds returned to feeders at least once -- some immediately, some months later. During spring and summer, most visits occurred in the morning and evening hours.
