Central Park's 'Bioblitz'

"Biologists and enthusiastic amateurs gathered for a BioBlitz, a 24-hour-long marathon in which they count as many living things in Central Park as possible. The counting began at noon yesterday and will end at noon today, when a census of Central Park's collective life — the first ever in a spot check like this, organizers say — will be tallied. There were bird counters, insect counters, bat counters and fish and aquatic invertebrate counters, including a group of divers aiming to plumb the park's lakes and ponds."
