Freshwater and Terrestrial Turtle Survey – Year Two

/0 Comments/in , , , , /by

by Eric Munscher

This year, we, members of the TSA – North American Freshwater Turtle Research Group (NAFTRG), had a team of ten people fly down to trap turtles on the BFREE private reserve in southern Belize. If you have never been to Belize, I highly recommend it. The country is beautiful and the people are wonderful. Working with the people at the BFREE Field Station on this project has been so much fun.

This is our second year of a planned 10-year survey of freshwater and terrestrial turtle species on BFREE’s 1,153-acre private reserve. Last year, we identified several species range extensions and caught seven of nine freshwater and terrestrial species known in Belize. The survey is valuable information not only for the TSA, NAFTRG and BFREE, but for the country of Belize where very little data exists on many of these species.

During the first 12 days we caught 221 turtles representing 8 species. The holy grail capture of this trip was finding our first Narrow Bridged Musk Turtle (Claudius angustatus), which is a really cool and understudied species of musk turtle. One that is not known from southern Belize. We ended up catching a dozen including some juveniles and a hatchling indicating a viable breeding population.

Our team also helped kick off a new grad student project for Collin McAvinchey who will be staying in Belize for most of the month of July tracking Tabasco Mud turtles (Kinosternon acutum). Collin’s project started off slow due to weather conditions. Finding adult Tabasco Mud Turtles was more of a challenge this year than last year. Still the data he is gathering is surprising and amazing. As of yesterday, he is now tracking ten of these turtles all over the rainforest. For a mud turtle they seem to act more like box turtles….

I am really looking forward to generating our first manuscripts from this work and seeing Collin’s thesis come together. I’m also excited to return next year! A valuable and exciting part of this program was the opportunity for citizen scientists to contribute to a long-term dataset. There will be opportunities next year for additional participation.

Thanks to an amazing crew Arron Tuggle, Madeleine Morrison, Nicole Salvatico, Stephen Ross , Tabitha Barbree Hootman, Luke Pearson, Becca Rádio Cozad, Georgia Knauss, and Collin McAvinchey. Also to the BFREE team: Thomas Pop, Barney Hall, Jonathan Dubon, Heather Barrett, Jacob Marlin, and many others, thank you for all of your efforts and hospitality and making this project such an early success! Finally, thanks to Tyler Sanville for supporting our travel logistics and to Eddie Pop who kept us well fed and always ready to get back out into the field.

Agami Heron Study

/0 Comments/in , , /by

Since 2016, I have served on the Agami Heron Working Group. This is a group of scientists and conservationists from throughout Central and South America working together to better understand a very secretive and therefore under-documented bird. My role is to ensure that we collect and submit annual nesting data on a small colony of Agami herons. Because the lagoon acts as nesting habitat for Boat-billed herons and Anhinga, we include them in our observation data.

In order to minimize disturbance of the colony, we make infrequent, short visits to the lagoon. Our goal is to determine if nesting has begun for the Agamis. The Boat-billed herons and Anhingas generally nest earlier in the year – March through May. Around the time that they finish their season, individual Agami herons begin to arrive and appear to investigate the area but do not stay.

In late June or early July, pairs of Agamis arrive and begin rebuilding their nests. They use the same nest trees and often the same nests as the Boat-billed herons. They do not appear to use the Anhinga nests which are usually situated higher in the nest tree.

Data Collection

The instructions for documenting the Agami nesting habits are straight-forward, but the timing of their nesting always has made the process a bit tricky. Our data collection begins when the birds are on the nest; however, we can’t visit too frequently. So, it is sometimes difficult to identify the most accurate start date. When we observe the birds on the nest, we document the date, number of nests, number of birds, and other habitat data and then quickly and quietly depart. We return ten days later to do another count.

When eggs begin to hatch and hatchlings grow, we continue to our count: focusing on number of eggs and number of hatchlings. We also look for evidence of parental care, possible predation, and growth stages. At the end of each successful year of data collection, reports are submitted to the Working Group for review.

Students from Keene High School participated in the first bird count at the lagoon for 2022. They documented 20 Boat-billed Herons – most on nests, 2 Anhingas on nests, and 1 Agami Heron.

About the Agami Heron Working Group

The Agami Heron Working Group established an action plan for the conservation of the Agami Heron in 2015. The plan can be accessed in English, French or Spanish. The Group will continue to provide an information exchange and coordination point for those interested in research and conservation of the species. 

New Rearing Pond at the Hicatee Conservation & Research Center

/0 Comments/in , , /by

Designed to study the reproductive biology and to determine if the Central American River turtle could be bred in captivity, the Hicatee Conservation & Research Center opened in 2014 and was met with immediate success when, in the summer of 2015, the first seven hatchlings emerged. This was followed by five hatchlings in 2016, 84 hatchlings in 2017, and 179 in 2018.

The extrusion welder was used to join hard plastic pond liner

The HCRC originally included two large breeding ponds, an overflow pond and several rearing tanks. The small rearing tanks at the center quickly reached capacity and HCRC staff identified an urgent need to provide the necessary space and improved environment for the 2018 hatchlings and the soon to arrive 2019 cohort. After much discussion, it was determined that converting the overflow pond into a large rearing pond for hatchlings and juveniles was the most cost effective and quickest solution to housing all the expected hatchlings now and in the foreseeable future.

We secured funding from Oklahoma City’s Zoo’s Care Grant Program and from Zoo New England to begin pond modifications. Additional support was provided through funding for supplies offered by Jacksonville Zoo and Gardens in 2018 and the purchase of a very important piece of machinery was made possible thanks to proceeds from the Turtle Survival Alliance’s 2018 fundraising auction.

Pond modification was slow to get underway due a very wet rainy season. However, during February and March construction took place and 140 turtles were placed in their new home in April. The rearing pond (Pond C) is forty-feet in diameter and approximately six-feet deep at the center. A six-foot perimeter fence will encircle the pond and fresh water is provided by solar powered pumps which were already in place at the facility. We will modify Pond C in the coming months to include a floating island and the planting of food trees and grasses as has been done in Ponds A and B. Our hope is that the facility will offer a healthy environment for all hatchlings produced at the HCRC until they are ready for release into the wild.  

Thanks to the Turtle Survival Alliance for their continued partnership on the Hicatee Conservation and Research Center. Thanks also to project sponsors: Oklahoma City Zoo, Zoo New England and Jacksonville Zoo and Gardens.

Team Hicatee Competes in La Ruta Maya

/0 Comments/in , , , /by

By Jaren Serano

The La Ruta Maya 2019 Belize River Challenge is considered one of the most gruesome races in Belizean history and it is the longest canoe race in Central America:  a four- day event covering over 180 miles of Belizean river. Paddlers from all corners of the country and internationally converge at the banks of the Macal River – the starting point of the race.

La Ruta Maya means “The route of the Mayans.”  This route was used by the ancient Maya for quicker access to the coast and, in the mid-1600s, by loggers to move logwood to the coast. On March 9, 1998, the La Ruta Maya was conceptualized by Richard Harrison of Big-H Enterprises when he launched a new brand of purified water. Since then, the race has evolved into an annual competition that brings together people from all over Belize and also raises consciousness about various environmental issues happening around the country.

Tom Pop, Scottie Trevino, and Rony Jimenez paddled for Team Hicatee during La Ruta Maya

This year BFREE decided to join in the action and partnered with Belize Wildlife Referral Clinic (BWRC) to create Team Hicatee. The primary reason for our participation was because this four-day river event is a major time when Hicatee turtles are harvested heavily for human consumption. We believed having a race canoe titled simply “Save the Hicatee” in this historic race  would be a strong message and a great platform to raise awareness for this critically-endangered species.

Team Hicatee consisted of three paddlers: Scottie Trevino, Rony Jimenez, and Thomas Pop of BFREE. Although this was Team Hicatee’s first time to compete together, they placed 31st overall and 3rd in their respective category (Mixed Category- one female and two males).

When asked about the race, Tom had the following to say: “It was tough and challenging but a very fun race. I did it for conservation to raise awareness for the Hicatee. If it wasn’t for them I wouldn’t travel that 180 miles.”

Team Hicatee placed 31st overall and 3rd in their category.

“This race is important because it helps locals to be more aware of the different conservation  issues around the country and it shines a light upon these issues.”

“Team Hicatee gave a challenge even though it was our first time, at the end of the day we were competitive. And I felt that my goal of raising awareness was completed because at the start of the race people didn’t even recognize us as competitors. But as the four days progressed we started hearing on-lookers yelling from the banks of the river “Go Hicatee Go!”  and that made me feel even more happy. They didn’t have to know who I was but the fact that they recognize our canoe and acknowledge that we were Team Hicatee made me feel like a proud conservationist.”

We at BFREE would like to extend a special thanks to Derric Chan of Friends of Conservation and Development (FCD), and Justin Ford, Belize Wildlife and Referral Clinic (BWRC), for their coordination and support of Team Hicatee.

Spring ’19 Hicatee Health Assessments

/0 Comments/in , , , , /by

 

Team Hicatee Spring 2019

During the early March Hicatee Health Assessment, a total of 214 turtles were assessed at the Hicatee conservation and Research Center (HCRC). The primary purpose of the spring health assessment was to perform a basic exam of the overall health of the captive population at the HCRC. Because oviposition takes place between the months of November and February, it was also relevant to check for the presence of additional eggs. 

Prior to the Health Assessments beginning, a small team of volunteers arrived to help prepare the site. The team cleaned hatchling tanks and moved the 140 hatchlings from the 2018 cohort from the soft release cage where they had been housed since December. They were placed there during the coldest months of the year because the water in Pond A maintained higher temperatures than in the smaller, above-ground tanks where they live during warmer months. Hatchlings were counted and given a quick check before being transferred back to the tanks where they acclimated until their assessments a few days later.

The three day processing started off with adult turtles being netted from the pond A, then placed in their respective holding area awaiting assessment. On day two, Adult turtles from Pond B was then netted and assessed. Day 3 commenced with a scanning of both pond perimeters for nest cavities which showed signs of eggs. Followed by the assessment of hatchlings from the 2018 cohort. Results from this year’s spring health check are still under analysis.

Cayle Pearson and Sarah Cristoff of Jacksonville Zoo and Gardens isolated several adult male turtles to collect additional data that will help them troubleshoot issues relating to the Hicatee turtles held in captivity at their facility.

We were grateful to receive support and assistance from the following participants in our spring health check: Dr. Isabelle Paquet Durand, Veterinarian at Belize Wildlife and Referral Clinic, Cayle Pearson, Supervisor of Herpetology, Jacksonville Zoo and Gardens, and Sarah Cristoff, Veterinary Technician, Jacksonville Zoo and Gardens, Heather Alford, Missy Belmer, Laurie Haven, Doris Dimmitt, Rodney Dimmitt, Tim Gregory, and Emily Gregory. We would like to express our gratitude to Jacksonville Zoo and Gardens for their financial support for this spring’s Hicatee health assessment.

The Hicatee Conservation & Research Center is a joint protect between BFREE and Turtle Survival Alliance. The bi-annual Assessments help ensure the health of captive animals at the HCRC and also contribute to our ongoing research of these critically endangered turtles. #savethehicatee

/0 Comments/in , , , /by

Next June, the International Herpetological Symposium (IHS) will held at the Best Western Plus Belize Biltmore Plaza in Belize City.  The mission of the IHS is to provide a forum for the dissemination of information and results of such research pertaining to the natural history, conservation biology, and captive management and propagation of amphibians and reptiles. Each year the IHS is held in a different location and is hosted by a Zoological, Herpetological, or Herpetocultural institution.

BFREE staff are scheduled to give several presentations and to participate in the conference which will take place from June 19-22, 2019.

Recent BFREE Volunteer and Wildlife Enthusiast, Brett Bartek, on the Bladen River

The International Herpetological Symposium in partnership with the Belize Zoo and the Crocodile Research Coalition are offering scholarships for young, Belizean wildlife enthusiasts to attend. The application can be found here.

For attendees looking to explore more of Belize either before or after the Symposium, there are several opportunities. BFREE is offering a post-symposium volunteership to work alongside the critically endangered, Central American River Turtle at our Hicatee Conservation and Research Center. This immersive opportunity is from June 24 – June 28 (1-week) or June 24 – July 5 (2-weeks). Volunteers will assist in all aspects of animal care for the captive population of adult turtles, juveniles and hatchlings. Email, tsanville@bfreebz.org for more information. 

Prior to the workshop, there is an exciting wildlife-focused 8-day Field Trip which includes three nights at the BFREE Field Station. Activities will include an in-depth tour of the Hicatee Conservation & Research Center and lots of hikes (both day and night) to search for cool reptiles and amphibians!

 

Celebrating Belize’s National Treasure – the Hicatee Turtle

/0 Comments/in , , /by

This October, BFREE, Turtle Survival Alliance, and our partners are observing the second annual Hicatee Awareness Month. Throughout the month, activities and events will celebrate the beloved Central American River Turtle – locally known as the Hicatee. This year’s message encourages national pride of this rare and unique species by seeking to establish the Hicatee as the national reptile of Belize.

As stated in the Belize 2016-2020 National Biodiversity Strategy and Action Plan (NBSAP), “Belize harbors a total of 118 globally threatened species (9 critically endangered, 32 endangered and 77 Vulnerable) and a further 62 near threatened / of least concern (IUCN, 2016). Of these, the critically endangered Central American river turtle (“hicatee”) is considered at highest risk of local extinction.”  

The Hicatee’s main predator is man. In effect, this turtle is being eaten to extinction across its limited range. Although it is believed that the Hicatee still exists in very small populations in northern Guatemala and southern Mexico, its stronghold is in Belize. Therefore, the future of the species depends on the actions of those who live in and visit Belize.

As the country’s national reptile, the Hicatee’s public status would be elevated and the stage would be set for national pride of this rare and unique species. Just as the Tapir and Toucan are revered and protected due to their status as the national animal and national bird, the Hicatee would be revered and protected if recognized as the national reptile.

To help prepare teachers for October, BFREE distributed educational packets to 100 preschools and primary schools in Cayo and Belize Districts. These are areas in which Hicatee have historically been found. Packets included classroom resources like activity pages and fact sheets about the Hicatee and other valuable and endangered wildlife found in Belize. “Herbert the Hickatee,” a book written by Ms. Gianni Martinez, a teacher at St. Mary’s School in Belize City, is featured in the packets. Also included is a national competition for students to design the 2019 Hicatee Awareness Month poster.

Camya Robinson, Research Assistant, and Jaren Serano, BFREE Science & Education Fellow and Author of “I am a Hicatee Hero,” posing with hatchlings 

On October 1st, BFREE emailed packets to principals of every school with a valid email address (540+) in Belize. These packet materials are available online for download at https://www.bfreebz.org. Special additions to the online packet include a poem for kids “I am a Hicatee Hero,” by Mr. Jaren Serano, alumnus of Sacred Heart Junior College in Cayo, and the 1 ½ minute video trailer for “Hope for Belize’s Hicatee: Central American River Turtle,” created by wildlife filmmakers, Richard and Carol Foster, of Belmopan.

With the second Hicatee Awareness Month, we are encouraging our Belizean and global partners to unite to help save this species from extinction. By making this our national reptile, future generations and leaders will recognize the important cultural and historic value of the Hicatee turtle – Belize’s National Treasure.

The hicatee is disappearing, but together we can save it.

 

Bi-annual Hicatee Health Assessments at BFREE

Dr. Isabelle and Dr. Jacobson do a full health review of a one-year-old Hicatee turtle

A team of veterinarians, zookeepers, researchers, and wildlife enthusiasts traveled to BFREE to perform health assessments on the turtles at the Hicatee Conservation and Research Center.  Our fall health check occurs when females likely have eggs, which allows the team to perform ultrasounds and determine the reproductive status of the turtles.

Day 1 Examinations were performed on the 2017 and 2018 hatchlings. Under the guidance of Dr. Isabelle Paquet-Durand, a veterinarian at Belize Wildlife and Referral Clinic (BWRC), and Dr. Elliott Jacobson, professor and veterinarian emeritus at University of Florida, each juvenile was weighed, measured and given a thorough exam which included careful assessment of warts and abscesses identified during previous examinations. Overall, turtles showed positive growth rates and reduction in skin problems.

The 2018 hatchlings were examined next – the veterinarians reviewed each of the 169 turtles which had already been weighed and measured on the 4th of September. Hatchlings also showed positive growth and good overall health.

Day 2 Adults and sub-adults were netted from Pond B in the morning and Pond A in the afternoon. Forty-four animals were measured and weighed and given general health examinations. All breeding sized females also underwent ultrasounds to determine the presence of follicles and eggs. One of the adult turtles eluded the nets, as did all the captive-born three and four-year-olds.

Gianni Martinez, teacher at St. Mary’s School in Belize City and author of “Herbert the Hickatee” joined the assessments on Day 2. 

Day 3 –  Because Dr. Jacobson was on-site to offer professional development training to HCRC staff, he presented a talk on “Zoological Medicine,” to the group.  Other lectures he gave throughout the weekend included “Animal Husbandry,” and “Reptile Collecting and Field Methods.”

Data collected during these assessments will add to the ongoing data set being constructed by staff of the HCRC.

Thanks to the Turtle Survival Alliance for providing funding for the Fall Health Assessments, Jacksonville Zoo and Gardens for loaning the portable ultrasound machine, and Columbus Zoo and Aquarium for providing turtle diet for continued feeding experimentation on the hatchlings. Additionally, thanks the team who contributed time, energy and knowledge to this fall’s assessment: Dr. Isabelle Paquet-Durand, Dr. Elliott Jacobson, Thomas Pop, Jaren Serano, Nichole Bishop, Saul Bauer, Cayle Pearson, Stephanie Verhulst, Gianni Martinez, Richard Zerilli, Eric Anderson, Jacob Marlin, Heather Barrett and Hyla Marlin.
