Welcome our new baby sloth!

We are so proud to welcome a new addition to the Upland Tropical Rain Forest exhibit – a Linne’s two-toed sloth was born in late August! The baby is the first born to Ivy, one of the four sloths in the exhibit, and is the third sloth born at National Aquarium.

During a daily routine checkup, National Aquarium staff observed Ivy carrying a newborn. The baby was born fully haired and already had its trademark claws! Staff are keeping a close eye on the two and have spotted the baby actively nursing. Upon initial observations, the baby sloth seems strong and healthy, and is actively clinging and crawling about on its mom. Animal care staff suspects the baby will continue to cling to its mother for the first several weeks of life. Sloths can remain dependant on their mothers for up to a year. As time goes on, the young sloth will begin exploring its immediate surroundings and eating solid foods.

Linne’s two-toed sloths are commonly found in South America’s rain forests, where they spend their entire lives in the trees. They are nocturnal by nature, fairly active at night while spending most of the day sleeping. Adult sloths are typically the size of a small dog, approximately 24–30 inches in length and about 12–20 pounds in weight.

Sloths have been an ongoing part of the animal collection at National Aquarium. The two oldest sloths currently living in the rain forest, Syd and Ivy, were acquired in May 2007 from a private captive breeder in South Florida. The other two sloths, Howie and Xeno, were born at National Aquarium in 2008 and 2010, respectively.

“Despite the fact that the two-toed sloth is a fairly common animal, many of its most basic behaviors are still a mystery because they are rarely observed,” commented Ken Howell, curator of Rain Forest Exhibits at National Aquarium. “We’re thrilled to welcome the new baby to our family and we hope that it will increase awareness and interest in this group of most unusual mammals.”

Ivy and her new infant are free roaming in the Upland Tropical Rain Forest exhibit and will be particularly good at hiding in the trees for at least a few weeks.

Stay tuned for more updates about our newest addition! 

We Have ANOTHER Spiny-Tailed Monitor Baby!

On Monday, a spiny-tail monitor baby hatched in our Animal Planet Australia: Wild Extremes exhibit backup area! We are so excited to have another baby spiny-tailed monitor join the one that hatched on July 6!

These babies will stay in our backup area in the care of our staff. Although our guests won’t be able to see the young, you can see their parents in the front.

Animal Update – August 17

Between our Baltimore and Washington, DC, venues, more than 17,500 animals representing 900 species call the National Aquarium home. There are constant changes, additions, and more going on behind the scenes that our guests may not notice during their visit. We want to share these fun updates with our community so we’re bringing them to you in our weekly Animal Update posts!

New baby screaming piha!

We have a new baby screaming piha in our Upland Tropical Rain Forest exhibit!

Screaming piha chick

Our screaming piha chick is the first to be born in captivity in North America. After a month of patient waiting by our rain forest aviculturists and exhibit curators, the baby chick hatched at the end of July. Our staff is very excited to be able to share the news of this successful birth!

Very little is known about the biology of the screaming piha when it comes to reproduction, and we hope to learn and share with others in the community as much as we can about these Amazonian birds.

Laying eggs can be difficult for pihas due to their poor nest-building skills. They create tiny nests. Ornithologist (the branch of zoology that studies birds) Alexander Skutch once described a piha nest as being “the most meager arboreal nest that I had seen.” Our female’s nest was about 2 inches by 2 inches and was constructed of curling vines from around our habitat. To help support the structure of the nest, our staff added two additional branches. Soon the female began to sit on her nest and after a couple of days we had our first spotting of a light brown, perfectly camouflaged egg!

In the wild, camouflage is an essential part of the piha’s survival. As a single parent, the female piha often has to leave to gather food while the chick relies completely on camouflage to stay safe in the nest. Through this hatching, we’ve learned that piha chicks lay motionless with their wings at their side while the mother is gone. The chick doesn’t peep or beg (behaviors we traditionally associate with baby birds), so as to not give away its location to any predators.

In the last month, our baby piha chick has grown tremendously. Thanks to a great mom, the chick has had plenty to eat and is completely feathered. Our new family is currently under the observation of our staff and is not on display yet in our Rain Forest exhibit, but we can’t wait for you to meet our new addition!

New Baby American Alligators at Our Washington, DC, Venue!

Our Washington, DC, venue has added four baby American alligators! They’ve traveled from Savoie Alligator Farm in New Orleans to stay with us for a year. These alligators are one of only two species that don’t spend their whole lives at the Aquarium because of their size. American alligators can grow to a length of up to 15 feet; we can only accommodate them until they reach about 5 feet in length. Once they’ve exceeded that size, we transport them back to their home and return with four new babies!

After going through standard precautionary measures to ensure their safety and the safety of our other species on exhibit, these gators are finally ready for their public debut. A brief quarantine period is essential to make sure that every animal in our care is stress-free and healthy. Animals that come to us from the wild are known to carry disease and parasites that could spread to other animals and even our staff, so it is very important to keep a close eye on all animals when they first arrive. Once our veterinarians and herpetologists determine that they have successfully finished their quarantine period, the alligators are given an exit exam and moved into their new habitat.

During the exit exam, our staff takes weight and length measurements, checks the flexibility of their limbs, and makes sure all those gator teeth are growing in properly. As of now, our baby gators each weigh about 3.5 pounds and are between 30–35 inches long.

Don’t let their size fool you! These baby alligators are strong; it takes more than one staff member to keep them calm and still to complete their exit exam.

The American alligator, a species once considered endangered, is now thriving in the southeastern United States thanks to state and federal protections and habitat preservation efforts. Fully grown, they can weigh 1,000 pounds and pulse through freshwater rivers, lakes, and swamps at speeds up to 20 mph.

We are excited to welcome them and hope you can come meet them in person soon!

Turquoise Tanager Chicks

We have two new turquoise tanager chicks in our Upland Tropical Rain Forest exhibit. This is the first time these birds have hatched eggs with us!

Turquoise tanager chicks

Turquoise tanagers are found in humid tropical forests throughout northern and central South America, as well as in Trinidad. Our exhibit houses two males and one female. Our turquoise tanagers began building a nest in one of the exhibit Cecropia trees in April 2012. Because the nest was high up in the tree, we were unable to confirm the number of eggs in the nest, but knew the female was sitting on at least one. After a short time, we were able to visually confirm that two chicks had hatched.

It is known that all adults within a turquoise tanager flock assist in feeding the nestlings and we were able to observe all three of our adults attending to the chicks.

Recently, we noticed the young birds’ growth and interest in leaving the nest. We covered both pools near the waterfall with netting to prevent their first tumble from the nest resulting in an accident. Once out of the nest and on the ground, we were able to transfer them to the corner cage where the adults continued to care for them. Our DNA tests have told us that one chick is a male and one is a female.

Both chicks are on exhibit (and still soliciting food from the adults) and we are very happy to announce that our turquoise tanager flock has grown from three to five!
