Honk if You're Flying South!

I pointed out some geese honking, and flying over our heads today to Deklan while we were outside. I tried explaining to him how geese fly south for the winter.

"When it gets cold, geese will fly south to a warmer place."
He was silent.
We went to Phoenix last year and he associates that with warm weather, so I tried again.
"Once it gets cold here, the geese have to fly down to Phoenix to stay warm."
Deklan: "How do they get there?"
"They fly..." I said, to which he stopped walking, looked up at me in awe and replied "like on a Geese Airplane!?"
