Bruce Peterjohn bands a female Rufous Hummingbird (Selasphorus rufus) at Annandale’s Green Spring Gardens. John Kelly takes notes.
“She weighs 3.4 grams,” Bruce said. “That’s an eighth of an ounce. You could mail eight hummingbirds with one first-class stamp. Of course, getting eight hummingbirds in an envelope could be difficult.”
