It's that time of year again when the team at Hunter Valley Zoo, Nulkaba get down and dirty to weigh and measure their group of American alligators. 

Timed with the start of the summer feeding season, this is wet, dirty and dangerous work for the zookeepers but an essential part of their alligator management.

It is also important to ensure all of the alligators are in tip top shape leading up to the breeding season.
