A Monitor First – Male Rosenberg’s Monitors Cover and Guard Nests

Water MonitorI remain awed by the learning abilities and complex behaviors evidenced by the Water and Lace Monitors I cared for at various zoos…spend time with any species and you’ll quickly see why.  Despite being popular study subjects, monitors are constantly surprising us.  For example, the current issue of The Journal of Herpetology (V44, N3, Sept 2010) documents an entirely new behavior for any monitor species – cooperative nest building and nest guarding in Rosenberg’s Monitor (Varanus rosenbergi).

Nest Defense by both Sexes

A 16-year-long study of this species on Australia’s Kangaroo Island has revealed that females guard their nest sites for up to 3 weeks after egg deposition, a behavior that has not been documented for any other monitor (3 species, including the Komodo Dragon, may return to the nest site on occasion, but seem not to remain nearby).  Amazingly, in 8 instances a male joined the female in protecting the eggs.

Florida Burmese Python Study – Snakes Cannot Survive South Carolina Winter

Burmese PythonIn 2008, a computer-based study by the US Geological Survey stated that Florida’s introduced Burmese Pythons (Python molurus bivittatus) might colonize up to 1/3 of the United States in time.  While the snakes’ presence in Florida is a severe problem, the release of this study generated a flood of illogical fears and predictions.  Recently, another study conducted by a noted herpetologist and utilizing live snakes has injected some sanity into the controversy.

Attracting and Collecting Earthworms – a Simple Technique

Earthworms are one of the most nutritious food items available for amphibians, and for those reptiles, invertebrates and fishes that will take them.  Collecting them (in one piece!) can, however, be frustrating, and they are quite costly at bait stores.  One trick I stumbled upon years ago has greatly simplified the task of supplying my collection with earthworms – I hope you find it useful.

Professional Herpetological Organizations and Journals – Part 1

False GharialI have belonged to local herpetological societies since childhood, and continue to be involved with several today.  A few, such as the NY Turtle and Tortoise Society, nicely serve both professional herpetologists and lay people…but whatever their leanings, all are of immense value.  Today I’d like to highlight some professional groups and journals that are open to everyone.

The Bronx Zoo’s Reptile House has copies of the “Big Three” – The Journal of Herpetology, Copeia and Herpetologica – dating back to the first issues of each, and in my 21 years working there I think I went through most of them!  Membership tends to be expensive (student rates are often available), so I summarize research notes from current issues and post them here on occasion (please see articles below).  Read More »
