This is a WOW thread. →[More:]
While I was waiting for the bus this morning, I watched a pair of crows building a nest. They were building it about 30 feet up in an ash tree that's just now budding out. In the immediate vicinity, there were several other equally tall trees that were already fully leafed out, and several that kept their leaves all year round.
But these crows, even though they prefer their nest concealed in order to protect their eggs and young from predators, were building in a bare tree.
I was kinda thinking, "Heh, stupid crows," until it dawned on me that these crows KNOW that the tree will be green and leafy by the time they start to brood.
And I went, WOW.
This is knowledge that they only have to use once a year, and it's not something they have to know, instinctually, in order to survive (as in, that owl is swooping for me, must fly off now). It's a bit of pretty arcane learned trivia for a bird: This tree is bare now, but within the next week or two it won't be anymore.
Wow.
What's made you go 'Wow' lately?
