It's nesting season. In April, the Reptile Discovery Center's Cuban crocodile Blanche built up a large mound nest. She constructed the nest by kicking up the mulch in the exhibit into a central location.

In March, female Cuban crocodile Rose underwent a series of tests to determine if she is still capable of producing healthy eggs. It all began with an egg — a perfectly smooth, white, oval-shaped, normally-sized egg — that Rose laid two months early. Nesting season for Cuban crocodiles does not...

The Reptile Discovery Center’s research on Cuban crocodiles continues! Currently, the team is listening for and recording vocalizations.

Keepers at the Reptile Discovery Center, including animal keeper Lauren Augustine, are upholding that proud tradition with ground-breaking research on social behavior, reproduction and play in a species not typically associated with any of those words: a crocodile.

Breeding season for our Cuban crocodiles ended in March, but staff continue to train the crocodiles to shift off exhibit. The hope is that when a keeper calls aloud for the crocs to shift, all of them will walk to the holding area in the back of their exhibit. Once they are in the holding, the doors...

By Lauren Augustine Remember those really important eggs we got back in May from Dorothy our 57-year-old Cuban crocodile? Well, we are now about half way through incubation. Five of the ten eggs are continuing to develop. We track development through a process called candling, this involves taking a...

By Lauren Augustine Summer has officially arrived in DC! And while visitors to the Zoo often flock to shade or the air conditioned buildings (like the Reptile Discovery Center), some animals are reveling in the heat—like our crocodiles. Crocodiles are ectothermic, meaning their body temperature is...

By Lauren Augustine I bet you didn't know that we train our crocodiles—that's right crocodiles can learn! We use operant conditioning techniques much like the mammal and bird keepers at the Zoo. There are a few reasons keepers at the Reptile Discovery Center use operant conditioning to train the...

She used her back legs to kick all the mulch, leaf litter and dirt in the exhibit into a large mound for her nest. This morning she looked as though she...
