What's New at the Zoo
Scaly Tales - Dave and Heather!
Heather and Dave are the two noise makers who greet you when you first enter the zoo. They are responsible for the beeps, chirps, and whistles you hear as you walk through the exhibits. They mimic the phone then answer "hello," they beep like the keys on the cash register while you're in the gift shop and confuse the employees who aren't quite sure if there's already someone helping you, and they repeat the sound of your camera shutter after you take a picture. When they're all alone and think no one is paying attention to them, Heather practices some of the many words she has learned over the years and Dave hones his cricket impression.
Dave arrived as a surrender after already having been through two owners. We decided to keep an ear out for another African grey to give him a friend, and eventually a friend of the zoo gave us Heather. Greys, like many other parrots, are social birds and tend to bond to a life partner. Without a permanent bird buddy, we would risk Dave bonding to a staff member. If the staff member left for any reason, the separation could be very traumatic for Dave.
African grey parrots are common pets, and live to be about 50 years or older. They are extremely intelligent, and it's important to keep them thinking. You'll often see toys hung up in their enclosure to give them something to play with and destroy. We love to get our visitors in on it by offering craft activities that allow people to build enrichment items with treats hidden in them for our African greys and macaws on special occasions. The most famous example of African grey intelligence is Alex the parrot. Dr. Irene Pepperberg studied Alex's capability to learn language through a variety of tests. Alex had learned over 100 words, showed an understanding of the concept of zero, and had just started being tested on optical illusions and his comprehension of written English sounds when he died suddenly at 31 in 2007.
African grey parrots' conservation status has been elevated from Least Concern to Vulnerable because of trapping for the pet trade. It is believed an estimated 20 percent of the African grey population is caught from the wild and sold in the pet trade. There is no sure way of telling whether your parrot is captive bred or wild caught, though a solid metal band around their legs can help indicate the bird was captive born. This band is slipped onto the parrot's leg when it's only a few days old, during a time when the bird is already rapidly growing. A few days later the bird has grown enough that the band can't come off. You can see Heather's band around her leg, but Dave's band fell off when he was younger. They are both captive born birds.

Scaly Tales - Akili!
Akili is another one of our residents who had been owned by a college student before coming to us. When he arrived 4 years ago he was about 30 inches long, and now he's about five feet from nose to tail and 30 to 35 pounds.
Akili is another staff favorite. They love him for his lazy, goofy, and sometimes clumsy personality. He's well known for finishing his meal and then falling asleep, mouth open and drooling, right over his food bowls.
Black throat monitors are native to Tanzania where they live in dry habitats, and they are the second longest and the heaviest species of monitor in Africa. They are terrestrial animals that will climb trees to escape predators, the heat, and to snooze, as Akili often does. They are a subspecies of rock monitor, meaning they tend to be a shorter and stockier type of monitor. Rock monitors, as well as most monitors in general, are noted for holding their ground in a confrontation and often will not try to hide when humans approach them. They will puff up and hiss when they feel threatened, and use their long tails as whips in addition to their sharp claws and teeth to defend themselves.
Monitors may actually be quite intelligent. Dr. John Phillips of the San Diego Zoo found that they could potentially count to six. Maybe behind that drooling, sleepy exterior is the mind of a monitor brainiac.

Scaly Tales - Spot!
Spot is another rescue story. A local college student owned Spot, and moved away during the semester without taking Spot with him, leaving him in less than ideal conditions. When we got him about a year ago the end of his tail had been damaged as a result of poor circulation, which was likely caused by inadequate heat. He was also a little underweight. However, as you can see, he's very happy in his new home.
Veiled chameleons like Spot are common pets, though by no means are they considered a beginner pet for reptile enthusiasts. They require specialized care, as well as a large enclosure they can have to themselves. They are a more aggressive and territorial species of chameleon. They are native to the mountains of Yemen, the United Arab Emirates, and Saudi Arabia. They are omnivores, and Spot is fed a regular diet of cockroaches, crickets, and salad. They are also ambush predators, like many other animals we have, and they will hold perfectly still for extended periods of time while they wait for a prey item to wander into view.

Scaly Tales - Sherman!
Sherman the savannah monitor came to us as a surrender about two years ago. GLZS staff love him for his quirks and calm demeanor. He is about 10 years old, and he is, unfortunately, a fraction of the size he should be.
Sherman didn't receive the best care, and is one of several residents we have here that highlight how the difficulties that can come with caring for a reptile pet can lead to health problems in the reptile - namely, poor nutrition and insufficient heat and humidity. He had trouble shedding completely due to poor nutrition and low humidity, and he is missing the ends of some of his toes as a result. He is partially blind as well. His vision has improved since he came into our care, and because of this we speculate it may also be related to nutrition. He loves eating - and who doesn't? - but due to his poor vision he occasionally needs to be tong-fed speedy cockroaches.
Sherman is living the good life at the zoo now. He's known for getting into strange and amusing positions while sleeping, sprawled out under his heat lamp, after a big meal.
Savannah monitors tend to be between two and five feet long. They are native to Africa, and often eat molluscs and arthropods in the wild. They may also give clues to how dinosaurs breathed. They can extract oxygen from the air when they're both inhaling and exhaling, a trait that was assumed only to belong to birds. It was thought that this method of breathing was developed in birds as a result of the high-oxygen demand of flight, and a marker of the evolution of warm-bloodedness as dinosaurs evolved into birds. In 2010, it was discovered alligators used unidirectional breathing, and later savannah monitors were found to use unidirectional breathing as well! Read more at National Geographic.
Sherman is up for adoption and needs an experienced owner that can provide the quality of care a monitor lizard in captivity requires. Sherman needs a large enclosure with deep bedding that will allow him to dig. He would most likely need a custom built enclosure, as a typical glass enclosure one would find in a pet store would be too small. He eats a varied protein diet that includes crickets, eggs, superworms, snails, and cockroaches.
Stop in sometime and say hi to Sherman!

Scaly Tales - Winston!
Winston is a staff favorite here at GLZS. He is a black and white Argentine tegu, which are the largest of the tegus. Many of you may remember that Winston arrived over a year ago after being left on our doorstep in a cardboard box one morning. He spent a long time in the biggest enclosure we had available - a 110 gallon tank, which was too small for him - he barely had room to turn around! Another enclosure opened up though, and now Winston has a much larger space to explore! He spends his days digging and napping in his log or under his lights.
Argentine tegus are known for being a more dog-like species of lizard in that they are friendly, inquisitive, and tolerant of being handled. Winston has charmed the staff here at the zoo with his big jowls and docile personality, as evidenced by the love notes on the door to his enclosure.
We are currently testing his disposition to see if he would make a good educational animal in the future to be used in our birthday party or field trip presentations. He has already made a few appearances and has been very well-behaved, so he may soon join our regular roster of educational animals!
Argentine tegus tend to live 15 to 20 years in captivity. They are omnivores and will typically consume insect proteins (as opposed to mice and other rodents) as well as fruits and vegetables. Black and white tegus live throughout Argentina and have adapted well to a temperate climate. They will often hibernate in groups during the winter. They are adept swimmers and have even been found far out at sea by fishing boats.
He would wave good bye, but those lights are... so... warm.... zzzzzzzzz...

Scaly Tales - Lawan!
One of our most popular exhibits by far is Lawan (pronounced LA-wan), our reticulated python.
Lawan has been a resident of the zoo since it opened in 2011. The man who donated her to us designed enclosures for large snakes for a living, and was well-versed in the care required for an animal like Lawan. He was kind enough to donate her so we could use for our exhibit and for educational purposes. In nature, reticulated pythons tend to exhibit a dark greenish brown and black pattern - Lawan's yellow coloring is known as a tiger morph. Pythons in captivity are often specially bred to exhibit a variety of colors. You will not find Lawan's coloring in a python in the wild. Reticulated pythons are native to Southeast Asia.
Lawan's size is the first thing everyone notices about her. Reticulated pythons are the longest snake species in the world, with anacondas being the heaviest. The longest reticulated python recorded in captivity measured 33 feet in length. We haven't weighed or measured her since we received her, but we estimate that she is 19 feet long and weighs near 150 pounds. We speculate that Lawan may still grow another 10 feet before she finally slows down. All snakes will grow throughout their lives, though they hit a certain length when their growth slows considerably.
We feed her a large rabbit once every two weeks. Snakes have a much slower metabolism than people, and they will typically consume a large meal once every few months. Reticulated pythons are known as ambush predators, meaning they tend to sit and wait for prey to walk by instead of hunting it. Her thick body shape in indicative of this, and can be observed on a smaller scale by comparing our sand boa (also an ambush predator) and our king snake, who has a lean body designed for seeking out and occasionally pursuing prey.
Sitting coiled and perfectly still for extended periods of time is something Lawan would be doing regularly in the wild while she waited for a large deer or pig to pass near her.
We don't quite know Lawan well enough to judge her temperament. She seems more curious than aggressive, but we still take many precautions when caring for her. The doors leading into her enclosure are padlocked and only the senior zoo keeper and curator are allowed to access it. Snakes' teeth tend to curve backward to help facilitate moving its meal down into its throat. The curved teeth also make it very difficult to spit out anything that's securely held in the snake's mouth, therefore, we tend to only clean her enclosure when she has her mouth full. We typically have about 20 minutes to clean up until she swallows her rabbit.
Lawan is easily our largest and most impressive resident. She is fortunate enough to have come to us from a good home, and she continues to thrive here while entertaining and educating our visitors. Stop by the zoo and meet Lawan!
