Twitchers

Apparently that is a term for "bird-watchers" this is what James Anderson writes in his Travel in Europe Blog has to say about twitching in Belize:

Another glorious attraction for twitchers is Crooked Tree Sanctuary in Belize (on the west side of the Northern Highway at Mile 33), featuring 276 species of waterfowl, as well as Morelet's crocodile, black bowler monkeys and otters and all Belize's species of freshwater turtle. This mosaic of lagoons is partly surrounded by the largest continuous stand of logwood trees remaining in the country. Especially in the dry season, which peaks in April, double-crested cormorants, egrets, herons and various ducks can be seen. In November the jabiru stork, the largest bird in the Americas, may arrive to build stick nesting platforms and raise its young by June. Crooked Tree also hosts the peregrine, the world's fastest falcon, which is powerful enough to grab an adult coot right out of the water. The Sanctuary is open every day.
