Our eastern hog-nose snake animal sign next to its exhibit at the Zoo will tell you the snakes’ natural range, diet, threat level and some other interesting facts. What no sign can convey is how theatrical these snakes really are: if there was an Academy Award for the most dramatic snake, the hog-nose snake would go home with the Oscar.

If a hog-nose snake is threatened, it has quite the repertoire of movements and behaviors to distract and evade an attacker. The first tactic the hog-nose snake will use is to flatten out its head, giving it the appearance of having a hood, like a cobra. It then will take a very deep breath to inflate itself and then release the breath causing a loud hissing sound. If this had not deterred its irritant, the hog-nosed snake will strike. The snake does not open its mouth to bite, it only strikes at the attacker by hitting the attacker with its nose and face. A lot of other snakes will use these same types of scare tactics to ward off an attacker; however, other snakes will typically bite when they strike. The rest of the hog-nose snake’s dramatic tactics are specific to this species.

When hooding up, hissing and mock-biting will not deter a threat, the hog-nose snake will flail around, appearing to be having convulsions. The convulsive fit includes the snake thrashing around with its mouth open with its tongue hanging out. This performance is ended by the hog-nosed snake rolling onto its back and playing dead with its mouth open and tongue hanging out. The snake will even go as far to appear to have blood coming from its mouth and anus, as well as defecating and excreting a foul odor. When the snake is picked up, it will be limp. If the snake is set back down with its belly down, it will quickly flip over so it is upside down on its back again. After some time has passed, the snake will pick its head up and check for danger. If the threat is gone, it will roll over and scurry away.

The eastern hog-nose snake gives the best performance when evading an intruder. There are other snakes out there that have their own tactics when being confronted by a threat, but none give the convincing dramatic performance like that of the eastern hog-nosed snake. The eastern hog-nose snake in the ECO center at the Zoo typically will not put on this dramatic performance because they have a pretty easygoing life and don’t have the need to act out. They are capable of it, however, and would give the performance of a lifetime if needed.

Listening to bats

New York bats are trying their best to bounce back from “white-nose syndrome,” a fungal disease first identified in 2006 in their overwintering caves near Syracuse. The mysterious disease has since spread across the eastern half of the United States & Canada killing more than 6 million bats. The little brown bat, once the most populous bat in New York State was decimated.

Zoo volunteers have for the past five years been assisting NYSDEC in monitoring bat populations after white-nose syndrome first appeared. We use a car-top mounted microphone and a lap top to record bat acoustics along 12, 20 mile routes in Western New York during June and July.

Each bat species has a specific echolocation “voice print,” allowing a safe and non-invasive way to characterize bat species diversity.  The bat populations being monitored travel every spring from the cave systems affected by the white-nose syndrome fungus, spending summers in Greater Rochester, Buffalo and the Southern Tier where our “batmobile” recordings take place.

Each recording session begins exactly at sunset. We then drive 20 miles-per-hour, recording bats as they echolocate their mosquito and moth prey above designated routes, from Canandaigua and Letchworth to Holland, New York.

The white-nose fungus originated in Europe where bats have, over time, developed an immunity. Let’s hope our New York State bats eventually share the same immunity attributes of their European counterparts!

As researchers study the disease process in the laboratory and caves, our Seneca Park Zoo batmobilers are providing NYSDEC with critical data on bat population trends in their summer homes across Western New York.  We thank Seneca Park Zoo “batmobile” volunteers for advancing science to save bats.

How can you help? Add a bat house to your yard providing a roost. Garden without pesticides and plant moth attracting wildflower gardens.

As many of you know, two elephants from Jacksonville, Florida now reside here at Seneca Park Zoo! Upon their arrival, I was given the opportunity to be the primary trainer for Moki to smooth her transition into her new home. As part of this duty, I had to learn what behaviors Moki knew so that I could ask for them while properly meeting the criteria of the behaviors. It has been very exciting to see the variations in behaviors that Moki and Chana know in comparison to Genny C and Lilac. More exciting than that, was to see Moki’s ability to “sit up,” even though she tips the scale at 8,600 pounds! Although this  behavior was trained to be performed on command many years ago, elephants in their natural ranges perform similar behaviors all the time. They will sit up in order to reach high branches to eat or when they are taking a bath, or even just to take a break! So next time you are at the Zoo, come say hello to our new residents and maybe catch Moki in a training session to see her amazing “sit-up!”   –Blog and photos by Jenna Bovee, Elephant Handler

In past blogs, I’ve tried to answer a few of the most common questions we get asked at the African penguin exhibit. Today I thought I’d tackle another one: “Where do the penguins go at night?”

Our penguins do not stay out on exhibit all night. During the warmer months, they come inside around 4 p.m., not only so we can thoroughly clean the exhibit for the next day, but also for their own safety and well-being.

  • During heavy mosquito months, penguins are susceptible to mosquito-born diseases such as Avian Malaria, Encephalitis and West Nile Virus. Though these diseases pose little risk to humans, they can be deadly to our penguins. Therefore, all standing water in and around the exhibit is removed, replaced or chlorinated every day during the time when penguins are off exhibit.
  • Bringing them in at night allows us to better control their environment. Although penguins can adapt to a range of temperatures thanks to their tightly overlapping feathers, it should be noted that the nightly low temperature on the coast of south Africa seldom drops below 50 degrees fahrenheit. The same cannot be said for many of our Rochester nights!
  • Because the Zoo is located within Seneca Park, there is always the possibility of a predatory animal intrusion into the exhibit. Such animals could include coyotes, foxes, raccoons and cats.
  • Lastly, returning them to their indoor holding area aids in pair bonding by allowing pairs to spend the night in their nesting boxes.

If you’ve ever visited the Zoo in the winter, you’ve probably noticed our penguins are seldom on exhibit. That’s because, while most people associate penguins with ice and snow, our African penguins would never encounter snow in their natural habitat and are not fond of the cold weather.

Therefore, as the days get colder, their time outside is limited. And once the temperature drops below 37 degrees fahrenheit, our penguins do not go outside at all.

For a behind the scenes look at our indoor holding facilities and how our birds get there, check out this video:

Bornean orangutan Bella and her parents Kumang and Denda have just been enrolled in an enriching research program where their decision-making and mathematical skills will be scientifically assessed on exhibit for Zoo guests to observe.

The University of Rochester Cognitive Sciences research lab of Dr Jessica Cantlon will be expanding its ongoing research with our olive baboon troop to include 36-year-old Kumang, 12-year-old Denda and 2-year-old Bella. Earlier this week, Denda demonstrated impressive finger and tongue dexterity skills in his first trial, starting with games and treats. The tasks will become more engaging and technical over time, advancing to double sided touch screens where Zoo guests will be able to watch the orangutans demonstrate cognitive skills.

“Bella is curious and playful,” says zoo keeper Mike Wemett. “As a zoo keeper, I have the privilege of watching her grow up and learn from her mother, and this research will track some of that development.”

Engaging science to better understand orangutan intelligence will help us advance novel approaches to designing new programs and exhibits that are stimulating and enriching.

Recently this year I was asked to help out a few of our ZooTeen Leaders by getting footage of the otters to be used in a conservation film.

Jack Fox, Aditya Tangirala and Eli Wipf then put together this video to educate people about the importance of the river otter to local ecosystems.

Our two female river otters, Heather and Sara helped by hamming it up for the camera and showing off their natural behaviors!

 

 

ZooTeen Leaders have  submitted their film to the Rochester Teen Film Festival. Finalists’ videos will be screened at 5:30 p.m on Wednesday, August 5, 2015 on the main screen at the Little Theatre in downtown Rochester. Good luck to the ZooTeen Leaders and we hope to see you at the festival!

In the fall of 2014, the Zoo’s fire-bellied toads were getting a new home located in the Oak classroom in the Z.O.T Zone. The idea was to give them a more natural habitat through a BOCES distance learning program.

The class would research the needs of the fire-bellied toads (Bombina orientalis), sketch out a design for an exhibit, and then build the exhibit to the specs that the team came up with. The kids learned about the natural behaviors of the toads and made sure that parts of the design to encourage these behaviors were included in the exhibit. Soon after, the toads moved into their new home.

The exhibit was a little over five times bigger than the previous one with new, improved habitat features. It incorporated a land area with moss, live plants, and plenty of hiding spots, including a coconut shell. There was a small waterfall which gently spilled flowing water back into a larger water area than they have ever had before.

There were plenty of vines tangled around the exhibit, too. The frogs were often hiding, but could be seen from time to time going from one side of the exhibit to the other. At feedings, they would always come out in the open.

The new exhibit, with all of the great features, created some unexpected results: it made it harder for educators to locate the toads to take on education programs. The waterfall was sometimes getting taken apart to gain access to them. So in an effort to simplify, we decided to buy a one piece waterfall with the pump housed inside. In order for the pump to run, we had to raise the water level a couple of inches higher than normal. Once the waterfall was in place and working, it made it much easier for educators to access the toads.

The water level rise also had another unforeseen consequence. The toads started to breed! They were often seen in amplexus, a type of mating behavior exhibited by some externally fertilizing species. Soon after, they laid their first clutch of eggs on May 13, 2015.

The tadpoles in the eggs quickly developed, and within a few days they were moving inside the eggs. A few days later they would all hatch and were about one centimeter in length. The tadpoles grew quickly!

I’ve read that fire-bellied toads take from one to five months to make the transformation into froglets. Ours have taken a little less than a month! The change in water level must have triggered the toads to start breeding. Who knew that such a subtle change in their life could make such a big difference!
