It is the dead of winter in the Northern Hemisphere, the Hummingbirds have gone south, and we're writing - again - about how to count them. For northerners, it's for future reference. The planet is tilting, spring will return, and so will the hummingbirds.

Last August we published a method of estimating the number of Hummingbirds you feed based on the amount of nectar disappearing from your feeders. The method we suggested came from a book about hummingbirds by Dan True who, in turn, based his methodology on a 1973 scientific study.
