COSI Connects Supported By:
Monday, August 24
American Museum of Natural History co-curator Ana Luz Porzecanski was on-air with La Mega Columbus 103.1 to share more about her work on COSI's ¡Cuba! exhibit.
Monday, August 31 Food: Cuban Sandwich
It's the first day of COSI's Digital Cuba Week! We will be joined by Pablo Taura, owner of Pablo's Havana Café in Powell, as he shows us how he makes a fan-favorite from his menu - the Cuban Sandwich! The Cuban sandwich is a variation on a ham and cheese sandwich, and originated from Cuban immigrant communities in Florida.
Tuesday, September 1 Art: Cuban Art
Michael Reese tells his story in this video. He was first exposed to Cuban art after a visit to the Pizzuti Collection. Since then, he has been regularly traveling to Cuba as a curator and consultant.
Wednesday, September 2 Dancing: La Guantanamera
Dancer and instructor Griset Damas-Roche from Plain City's U Will Dance Studio shares choregoraphy for Celia Cruz's "Guantanamera" for Day 3 of Cuba Week!
Thursday, September 3 Food: Black Beans Recipe
Lourdes Barroso de Padilla, Director of the Latina Mentoring Academy, shares her family's recipe for authentic Cuban black beans for Day 4 of Cuba Week.
Friday, September 4 Music: The Alonso Brothers, Mambo No. 5
For the final day of Cuba Week, watch pianist Orlay Alonso and his brother, Orlando, duet "King of the Mambo" Pérez Prado's Mambo No. 5. Prado was a pianist and composer known for popularizing the mambo in the 1950s - Mambo No. 5 was one of his greatest hits!
Cuba is teeming with amazingly unique wildlife and we are fortunate to be able to display a few live specimens for an up close look.
Cuban Tree Frogs
The Cuban tree frogs were brought in for the Cuba exhibit, but will be absorbed into our permanent collection once Cuba finishes its run. They love soaking in their water dish and are always active during feeding time when crickets are added to their display.
These frogs were collected from a wild invasive population in the southern United States. While they are an important species in their native range, they are much larger than native U.S tree frogs and they not only out compete them for food, but will eat native frogs outright!
Genus/Species: Osteopilus septentrionalis
The anoles in the Cuba exhibit are on loan from another institution for the run of the exhibit. The bearded anole loves to be misted and enjoys drinking from his dripping plant, but otherwise prefers for us to leave him alone.
Bearded anoles are also known as false chameleons due to their similar physical appearance. One of the main differences are his toes which are adapted to climbing in the canopy of the forests in Cuba.
Genus/Species: Anolis barbatus
"Montoya" - Boa Constrictor
Montoya is currently on display in our Cuba exhibit and came to us from a reptile rescue where he had been surrendered. While this species is common in the pet industry, most people don’t realize how big they can get with females reaching 10 feet. This can result in them finding their way to a rescue or sometimes even being introduced to the wild where they pose a threat to native wildlife.
While this boa species is found on the mainland from Mexico to Ecuador, his Cuban cousin is found exclusively in Cuba and has been observed hunting fruit bats collectively at the mouths of caves.
Genus/Species: Boa Constrictor
The anoles in the Cuba exhibit are on loan from another institution for the run of the exhibit. The smallwoods anole not only has beautiful colors that help him blend in to his environment, but they will change depending on his mood. He also has a flap of skin on his chin called a dulap which he will flare to make himself appear bigger. It also lets us know that this individual is a male.
This species is a “crown-giant ecomorph”; crown - they are found in the crown of the tree; giant – they are very large for an anole species; ecomorph – a species that occupy the same niche in the same microhabitat.
Genus/Species: Anolis smallwoodi
Did you know that COSI is home to several animals, including snakes, opossums, chickens and turtles? We have around 40 different species in house averaging 60 individuals and 11 separate colonies. You can meet some of them here through our virtual wild experience.
"Big Sis" and "Little Sis" Eastern spotted turtle
Big Sis and Lil Sis are in fact both boys. They received their names before being identified as such and the names just never changed. What they lack in size (adult spotted turtles stay under 6”), they make up for in attitude. The “Napoleon complex” would be a fitting term for these feisty little turtles. They can be “spotted” in our Lily Pad exhibit.
Spotted turtles are a federally endangered species. Reasons for their population decline include the loss of wetlands where they live, an increased number of their top predator – the raccoon, as well as the black market pet industry. If you “spot” one of these turtles in the wild, be sure to keep that location to yourself so you don’t accidentally tip off an illegal pet trader.
Genus/Species: Clemmys guttata
Chum" and "Bucket" Eastern Box Turtle
Bucket has been with us for many years and was donated by a family who had kept her as a pet. In 2016 during a routine vet check, we discovered that she started carrying unfertilized eggs. Given her popularity with our guests, we decided to add another rescued box turtle to our collection to give Bucket some space while she laid her eggs. This is when Chum joined our team. Both turtles live together harmoniously.
Regulations regarding housing of this species have changed over the years as their populations have declined. It is currently illegal to house any native Ohio species without appropriate permits in an effort to protect and restore populations.
Genus/Species: Terrapene carolina carolina
"Arrchimedes" Eastern Screech Owl
Arrchimedes is an Eastern screech owl that was found injured in the wild and was brought to a wildlife rescue to be rehabilitated. Unfortunately, she is unable to catch live food as a result of her injuries and is therefore unreleaseable. She has adjusted well to living here at COSI and is a solid little program bird that allows for a rare opportunity to see one of these owls up close.
These owls are common here in central Ohio, though they are very difficult to find! Instead of looking up into the trees to try and find them, look around the base of the tree for castings (pellets) and droppings (distinctive white urates). Once you find these identifiers, that’s the tree you will want to keep an eye on.
Genus/Species: Megascops asio
"Patches O'Houlihan" Virginia opossum
Patches O’Houlihan was rescued from being attacked by a dog but suffered a spinal injury that affects his mobility. His injury resulted in him being non-releasable which is how he found a home here at COSI. He enjoys walks out in Big Science Park and is part of various animal programs we offer. Virginia opossums are fascinating marsupials (!) with terribly short lifespans of only 2 years. This August, Patches will be considered an old man.
Genus/Species: Didelphis virginiana
"Toothless" Eastern Hellbender
Toothless is a 2018 hatchling on loan from the Ohio Division of Wildlife. He is a part of a conservation effort to help save this endangered species here in Ohio. He is currently on display in our Lily Pad exhibit.
Hellbenders are the largest amphibian in Ohio reaching up to 2’ in length! They also have some of the best nicknames in the animal kingdom: Snot otter, Allegheny alligator, Grampus, and Old lasagna sides, just to name a few.
Genus/Species: Cryptobranchus alleganiensis
