Homicide: Life on the Street1993

[Bolander sees bird droppings on his car]

Det. Stan Bolander:
Would you look at this? Pigeons!

Det. John Munch:
Not from a pigeon, it's from a waterfowl.

Det. Stan Bolander:
A what?

Det. John Munch:
A waterfowl. From a mallard.

Det. Stan Bolander:
A duck?

Det. John Munch:
A well-fed duck.

Det. Stan Bolander:
Right, like you can tell the difference. That couldn't come from a seagull, I suppose?

Det. John Munch:
No, gulls have a milky white splurter. Notice the lobular pattern, these splays within splays.

Det. Stan Bolander:
Munch... why do you know these things?
