LORELAI: What are you people doing?
LADAWN: We’re watching hummingbirds.
WOMAN: They’re still out there if you wanna scooch in.
MAN: They’re the darndest things. Flap their wings a hundred times a second. It’s an engineering marvel.
The hummingbirds the B&Bers are watching are most likely Ruby-Throated Hummingbirds (Archilochis colubris), the most common hummingbird in the eastern states of the US, and found during the summer months. Other species of hummingbird have only been rarely sighted in Connecticut. Unfortunately for this episode, Ruby-Throated Hummingbirds are solitary and aggressive towards others of its kind, so there would not be multiple hummingbirds to see all at once.
This species of hummingbird can flap its wings up to eighty times a second – quite close to a hundred times a second.
