(AP)—From aardvarks to zebras, the residents of London Zoo are coming forth to be counted.

Dozens of zookeepers—brandishing both clipboards and snacks to coax out reluctant creatures—are recording every mammal, bird, fish, invertebrate, reptile and amphibian as part of the 's annual animal census.

The zoo is home to 19,000 animals of more than 850 species, from 400-pound (185-kilogram) silverback gorillas to insects such as the tiny leaf-cutter ant.

New arrivals this year include a baby Malayan tapir, two flamingo chicks and the first spiny-headed lizards born in Britain.
