It’s Valentine’s Day, and love is in the air! Whether it’s love for your partner or a friend, or it’s love for your own wonderful self, you probably won’t be able to escape thinking about it for at least a few minutes (…sorry!). In the spirit of love, we wanted to use today’s blog to hone in on the Association of Zoos and Aquariums’ Species Survival Plan (SSP), with a spotlight on our screaming hairy armadillos, Lenny and Rizzo.
In captivity, the screaming hairy armadillo population is dwindling. There’s a whole host of reasons for this, but the main ones are that there aren’t enough successful breeding pairs out there, coupled with low reproductive rates. Per the recommendation of the Association of Zoos and Aquariums (AZA), we’re crossing our fingers that Cupid’s arrow will fly and find its mark with our armadillos. Lenny, who you can find on exhibit in our Discovery House, and Rizzo, our back-of-house armadillo, are a part of a very detailed strategy for successful captive breeding.
During Rizzo’s ovulation cycle, which occurs during only two seasons of the year, the armadillos are given up to two months together in hopes that the spark of love will ignite. Lenny will even spend his evenings in the back-of-house so that he and Rizzo can have more time together. Since gestation takes from 60-80 days, and if conception were to occur early on in her mating period with Lenny, Rizzo could give birth while still in the company of her mate. This leads to a high level of stress for the potential mother and could lead to her eating her offspring. To avoid these things, a pregnant Rizzo would have to be moved entirely out of Discovery House and taken to a low-stimulation environment in which she wouldn’t even be able to so much as smell her mate, Lenny.
When and if babies are successfully produced, litter size is small – consistently yielding twins. The two are initially quite fragile, as babies are. So along with the obstacles leading up to a successful pregnancy, keeping the babies healthy and sustained can be a trial in itself.
The odds could seem insurmountable, but our keepers are doing everything they can to ensure the possibility of a successful breeding with our screaming hairy armadillos. With the help of AZA and our partners in other accredited zoos, we are learning how best to guide this species to a better future.
