"Where'd you get the coconut?"
"We found it."
"In Mercia?"
"Yes."
"Coconuts are tropical."
"So?"
"This is a temperate zone!"
"The swallow may fly south with the sun, or the house marten or the plummer may seek warmer climes in winter, but these are not strangers to our land..."
"Are you suggesting that coconuts migrate?"
"Not at all; They could be carried."
"By what? A swallow?"
"It could grip it by the husk."
"It's not a matter of where it grips it. It's a simple question of weight ratios: a 5 ounce bird can NOT carry a 1 pound coconut."
This whole skit popped into my head when I imagined migratory mammal coconuts.
