Great Blue Herons fly with their necks folded - Sandhill Cranes and Roseate Spoonbills fly with their necks extended.

I used to keep a small houseboat at Sweetwater Resort - a now defunct fish camp. There was a problem once.... fish were disappearing from the bait tank every night. The bait tank was a fairly large cement structure outside, by the canal. At first we thought that some fisherman must be sneaking up at night and stealing bait. Day after day they would restock the tank, but every morning the fish would be gone.
