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.
LUKE: It’s not biologically natural for people to mate for life. Animals don’t mate for life. Well, ducks do, but who the hell cares what ducks do?
In fact ducks don’t mate for life – most duck species, such as mallards, are monogamous, but for only for a single breeding season (a possible foreshadowing of the length of Max and Lorelai’s bond).
Some sea ducks are thought to return to the same partner when they make their way to the breeding grounds, but this is hardly the same as what a human marriage is generally like. In a few species of stiff-tailed duck, polygamy is the norm, with one male mating with several females.
Furthermore, even within pair-bonded duck couples, promiscuity is reasonably common – they are socially monogamous, not necessarily sexually monogamous.
RORY: God, look at that. It’s like he’s eating her face [of Tristan and Summer].
PARIS: Okay, that’s it. I’m getting the fire hose.
Paris means to use the hose to force Tristan and Summer apart – a common way to separate fighting dogs is to spray them both hard with water from a safe distance, so she’s comparing them to animals.
We learn from Lorelai that Jackson cultivates his own mealworms to help fertilise his plants.
Mealworms are the larval form of the mealworm beetle (Tenebrio molitor), a type of what is called “darkling beetles”. Originally from the ancient Mediterranean region, they have spread all over the world.
Mealworms can be raised to produce composted garden fertiliser from their castings (manure), in the same manner as worm farms. This seems to be why Jackson is cultivating them.
Emily tells Lorelai that the cover of the latest Chilton newsletter is a picture of a spotted owl, and that Chilton is taking donations to help them; she sent a donation in Rory’s name.
The spotted owl (Strix occidentalis) is a species of bird that lives in old growth forests on the west coast of North America, ranging from Canada to Mexico. Due to destruction of its natural habitat by logging, it is currently classified as a near-threatened species, with numbers continuing to decrease.
