Celebrating International Vulture Awareness Day at the Dallas Zoo

Help us #SaveOurScavengers

 

Known as “nature’s clean-up crew,” vultures have a pretty dirty job. But they play such a vital role in their ecosystems, and they help out humans too! Unlike other birds of prey vultures are scavengers, which means they eat carrion (aka, dead animals). This helps prevent the spread of diseases such as rabies, anthrax, cholera, botulism, and tuberculosis, which can often be found in those animal carcasses.

What a thankless job. Luckily, vultures are equipped with adaptations that help them thrive in this role.

  • Vultures’ highly acidic stomach acid and super strong immune system allow them to eat decaying and potentially infectious meat that would make most other animals sick.
  • Some vulture species rely on keen eyesight to locate their food; others rely on their keen sense of smell to search out hidden carcasses by detecting gasses that are released during decomposition.
  • Vultures will vomit up semi-digested food to ward off predators, or to help lighten their weight if they need to escape from a predator quickly.
  • Many species of vultures have bald heads – there is speculation that this helps them stay clean, but this may also help them with temperature regulation.

Unfortunately, these amazing birds are under siege when it comes to survival.

  • 16 of the 23 vulture species in the world are considered threatened, endangered, or critically endangered.
  • Vultures have been disappearing from Africa at an alarming pace over the last 30 years, having declined between 62-95% across the continent.
  • Globally, vultures are the most endangered group of birds.

Vultures are being poisoned by the thousands, especially in Africa and Asia; sometimes indirectly by farmers who poison large carnivores that threaten their livestock. The vultures consume the poisoned carcasses, and die as a result. More alarming is that poachers have begun intentionally poisoning the carcasses of poached animals to kill off vultures who may give away their location to authorities.

Which is why the first Saturday of September is now known as International Vulture Awareness Day, to help raise awareness about vultures and the conservation issues they face around the world.

Vultures at the Dallas Zoo

We love our vultures here at the Dallas Zoo! We care for eight different species, and we take pride in educating our community about the importance of saving these amazing birds.

You may have seen our black vulture, Baldwin, strut his stuff on the Wild Encounters Stage. Baldwin has been making our guests fall in love with vultures since 2016, when he came to us from a local rehabilitation facility. Fittingly enough, his third birthday falls on International Vulture Awareness Day this year.

“We love introducing Baldwin to our guests!” says Robin Ryan, Supervisor of Animal Encounters. “He has such charisma and personality, which I think can inspire people to see vultures in a more positive way.”

We’re also celebrating International Vulture Awareness Day throughout the weekend, during our special Member Mornings events this Saturday and Sunday. Members can join us for a private Vulture Keeper Chat both days at 8:30 a.m. in front of the vulture habitat, and we’ll have special vulture-themed arts & crafts projects.

We hope you’ll join us in wishing Baldwin the happiest of birthdays. And use International Vulture Awareness Day as your incentive to help us change this species’ reputation – toss out some of the fun facts above and tell others about these crazy-cool birds.

Chicks galore! Another epic breeding season for bird team

Dallas Zoo’s bird curator, Sprina Liu, guest blogs on ZooHoo!

It’s been another banner breeding season for the bird department and I’m here to share some of our successes! Each species has their own specific breeding season timeframes, so to truly say we’re done is not accurate. As I compose this, there are still more than two dozen eggs in incubators and nests. So while we’re not quite done yet, things are slowing down. We have a great team that works hard throughout the year and they’re the reason we are as successful as we are.  Here are just a few of the highlights:


_MG_1935-Caribbean flamingo chick-CB _MG_8812-lesser flamingo chicks-CB

Flamingos: Some of my favorites! We kicked off 2016 with another productive season with our lesser flamingo flock welcoming four chicks. More recently, we had an addition to our Caribbean flamingo flock in late June. Hopefully everyone caught the little cutie on social media!


_MG_3836-King vulture chick-CB
King vulture: We hatched this little one at the end of April. He/she has not left the nest yet but you might be able to catch a glimpse of this now large white fluff-ball peering out from the nest box in ZooNorth’s Wings of Wonder.


_MG_9920-spoonbill chick-CB
African spoonbills: A record year for Dallas Zoo! We welcomed eight chicks – the most we’ve ever hatched. The breeding flock surprised us this season after they fledged their first five chicks. Normally once they’ve reared, they haven’t wanted to nest again. But we spotted the birds exhibiting nesting behaviors, so we encouraged them and three additional chicks hatched! This is unprecedented. Great observation skills by our keepers made this our best year yet. Although the main flock is off exhibit, you can see African spoonbills in our lesser flamingo habitat in the Wilds of Africa.


_MG_3856-Fulvous whistling duckling-CB _MG_8762-Ruddy Shelduck ducklings-CB

Waterfowl: We bred two species of waterfowl this year: a clutch of fulvous whistling ducks (left), and ruddy shelducks (right). Who doesn’t love ducklings? They’re still off-exhibit at the moment but you can see fulvous whistling ducks in the Zoo North flamingo pond and ruddy shelducks in the Wilds of Africa forest aviary.


_MG_8071-two baby penguins 2-4-16 CB
African penguin: Another one you may have caught on social media! Resident breeders Tazo and Tulip raised two chicks this season. Our two boys are doing well and have joined the rest of the flock on exhibit in Penguin Cove.


_MG_2161-marabou stork chicks in nest 4-19-16
Marabou stork: Dallas Zoo is making huge contributions to this zoological population. With 15 birds, we hold the largest population of this species in the North American region and bred three chicks this year, more than anyone else! Our management strategy and daily efforts with the birds paid off—one additional female that has never bred before raised a chick, and a second female that hadn’t bred laid two clutches of eggs. Though her eggs were not fertile, we have high hopes in the coming years! Look for these birds on the Wilds of Africa Adventure Safari.


_MG_1127-Yellow-billed stork-CB

Yellow-billed stork: Dallas Zoo continues to play an important role with this species as well. This group is currently off exhibit, but we’re working on getting some on exhibit for everyone to enjoy. The group has produced two chicks this season. The interesting fact about this year is that they’re still not done! Like the spoonbills, the pairs, after rearing their chicks, are nesting again and this is unprecedented behavior for our group. The success of this bonus nesting period isn’t seen as we have eggs incubating and other pairs back nest building. Though we won’t know if the eggs are viable yet, it is a success in itself that the birds are still wanting to nest this late in the year.


_MG_2137-white-backed vulture chick-CB

White-backed vulture: Facebook goers should know about this one, too! Our little boy is not so little anymore. He hasn’t left the nest yet, but he’s working on figuring out his wings. Like his older sister in 2015, he is the only one of his species bred this year in North America. This important little guy brings the current U.S. population to 12 and for this critically endangered species, a successful breeding program may be crucial to aid their wild counterparts. We are very proud and honored to have received special recognition earlier this year from the AZA Avian Scientific Advisory Group for our achievement with this species. He can be spotted with his parents in the Wilds of Africa aviary across from the Simmon’s Hippo Outpost area currently under development.


As you can see, we’ve had quite the year so far, and these are just the highlights. We bred quite a few other species in cooperation with SSP recommendations and other facilities that were not even mentioned above but we’d be here all day! We’re looking forward to a short break (shorter than usual!) before this fall when we’ll be starting it all back up again. More updates to come!
