Let’s Talk Babies: Oryx vs Human

Let’s Talk Babies: Oryx vs Human


With the addition of our new scimitar-horned oryx calf, we wanted to highlight how oryx calves grow and develop. How long is a female oryx pregnant? Can the calves stand right away? How long do they stay with their mom? We are going to answer all these and more! But that isn’t all we will be doing. We are also going to see how a growing oryx baby compares to a growing human baby. It may shock you just how different the development process is for some animals when compared to humans. We don’t typically think about it, but it can be interesting to compare the two and see how similar or different they are!

Scimitar-horned oryx can breed year-round when environmental conditions are right. They have a gestation period of about 8-8.5 months and usually give birth to a single calf, which weighs around 22 pounds (that’s as heavy as a full-grown dachshund!). Similarly, humans can also have a baby at any time during the year and, with a nine-month gestation period, it is very close that that of an oryx. Did you know that most human babies are born between July and October? August is the most popular month for births.
Like the oryx, humans typically give birth to one baby, however there is the possibility of twins, triplets, all the way up to octuplets (but that is very rare)! Human babies don’t quite weigh the same as an oryx calf. The average weight for a human baby is 5-5.8 pounds, which is nowhere near 22 pounds. Overall, not too many differences so far, but let’s look at development after birth.

Oryx calves can get up and walk just a few hours after birth. But the calves don’t get to join the rest of the oryx just yet since the mothers hide them for 2-3 weeks before rejoining the herd. At around 2 weeks old, calves begin nibbling on solid food, and after 4 months they can feed on their own. At this time, they will leave their mother, but remain in the herd. Oryx are considered mature at around 1-2 years old.
Now, I’m sure you can already tell there are some major differences between oryx calf development and human baby development, but let’s compare! A baby’s first steps are a pretty big deal; but instead of them happening a few hours after birth like the oryx, it usually takes 8-18 months for a human to start standing on their own two feet. And while the oryx can eat solid food early on, it’s going to take around 6 months for a human baby to be able to eat food other than formula/breast milk. Most of us are going to remain with our guardians until we are 18 years old. But could you imagine setting off on your own at 4 months like the oryx? In most countries, we are considered adults once we reach 18 years of age, but our brains continue to develop until we are 25-30 years old! It’s crazy to think oryx are already mature at 1-2 years old. When I was 1, I barely had any idea what was going on!
Whether it be a human baby growing a first tooth or an oryx baby getting it’s adult markings, it’s exciting to watch any baby grow and reach milestones throughout their life. We hope you enjoy getting the opportunity to watch as the newest member of our oryx herd grows up!

National Wildlife Day

That’s Wild! Celebrating National Wildlife Day

National Wildlife Day is celebrated yearly on September 4th. Created in 2005 by animal behaviorist, philanthropist, and conservationist Collen Paige, National Wildlife Day is a day to educate the public on the importance of wildlife, including the wildlife in their own backyard, and bring attention the threats these animals face. It was also created in honor of the late Steve Irwin, a beloved and renowned conservationist!

It is estimated that more than 1 million species will face the threat of extinction in the coming decades. Species such as the black rhino, hawksbill turtle, and gharial are already considered critically endangered, meaning they are at an extremely high risk of extinction. But why should you care? I’m glad you asked! Wildlife is important to us for many different reasons. Here are just a few:

Ecological balance. Animals of all shapes and sizes help maintain the balance of the ecosystems they live in: predators help with population control, butterflies, bees, and even bats pollinate plants and flowers, small mammals maintain soil health, fruit-eaters disperse seeds, etc. An ecosystem must be in balance for it to function smoothly and remain healthy. Wildlife also helps maintain biodiversity within the ecosystem. Without a wide range of animals, plants, and microorganism, our ecosystems would collapse, which would be bad considering we rely on healthy ecosystems for clean air, fresh water, and food. Removing just one animal could cause the entire ecosystem to change.

Scientific value. Wildlife can be studied to learn more about the natural world and can help us create conservation strategies that will further aid in the preservation of many different species. Wildlife also has medicinal benefits!Did you know that toxins found in venom can aid in the treatment of certain medical conditions, and that there are already several venom-based medications already in use? For example, the main compound of Captopril, which is used to treat high blood pressure and reduce the risk of heart failure after a heart attack, is derived from the venom of a pit viper species found in Brazil!

Economic value. While not always obvious, wildlife can benefit farmers greatly through the ecological services they offer. Pollination is one of the most valuable ecological services wildlife can provide. Many of the fruits and vegetables we enjoy on a daily basis require pollination. The more pollinators around the better crop yield there will be! Wildlife can also be a great form of natural pest control. Some of the best pest controllers are right in our own back yards. From raccoons to bats, wildlife help keep our gardens and farms free from pests that might destroy them.

So, now you know just a few reasons why its important that we celebrate wildlife, and there are many ways you can do this. You can visit a wildlife sanctuary, go on a nature walk, volunteer and an animal rescue or conservation facility, or even plant native plants! Take some time to get out into nature and appreciate all wildlife does for us.

National Honey Bee Day

National Honey Bee Day

 

Happy National Honey Bee Day! Occurring on the third Saturday of August each year, National Honey Bee Day celebrates honey bees, beekeeping, and beekeepers. Bees are a crucial member of local ecosystems and pollinate 80% of the world’s plants, including 90 unique food crops. Honey bees who have found vital food sources will come back to the hive and preform a ‘waggle dance’ signaling the direction and amount of food available. The closer the food and the more food there is the more ‘waggle’ there shall be! The bees with the best waggle are deemed the ‘winners’ and their food source will be harvested first – imagine having dance offs to decide your dinner location.

With over 16,000 people employed across beekeeping, beekeepers and other workers are necessary to the survival and future of honey bees and the various plants they pollinate. Colony Collapse Disorder, or CCD, has led to half of the world’s honey bee colonies disappearing since the 1940s. We can help honey bee populations by planting native backyard gardens with some of their favorite flowers and plants, such as rough aster. Urban beekeeping and the beekeeping community have been able to help urban honey bee populations by providing re-homing for unwanted bees, urban hive havens, and community bee yards. 

Recognizing Our Honey Bees

 

Buzz, buzz, buzz! Though there are over 20,000 known bee species and over 4,000 natives to the United States, honey bees are recognizable by their warm amber-brown body color, striped abdomens, and heart-shaped faces. Honey bees have two unique forms of identification not found in most other bees large hairy compound eyes and the lack of tibial spurs. Hairy compound eyes large enough to see with a lens or phone camera aid honey bees allows for enhanced vision. Next time you see a bee you think might be a honey bee, try to use your phone’s camera to check out the eyes! The lack of tibial spurs (spurs on the hind legs to assist in digging) typical of nearly every other bee species is due to their housing in wax comb homes instead of holes in the ground or various cavities.

 

The Life of an Honey Bee

 

A honey bee hive, consistent of a hexagonal wax cells forming a comb, houses three types of bees – the queen bee, drone bees, and worker bees. The queen bee lives between three to four years and can lay up to 1,500 eggs a day, with her sole purpose to lay eggs which will become either worker or drone bees. Worker bees – the workhorses of the honeycomb – are non-reproductive females responsible for all tasks other than mating with the queen or laying eggs: gathering nectar, guarding the hive, caring for the queen and all larvae, cleaning and maintaining the hive, and producing and storing honey in the honeycombs. These bees will usually leave the hive around 15 times per day and visit upward of 1,500 flowers a day! Drone bees are only males and primarily exist to mate with the queen bee. These drone bees do not have stingers and never leave the hive to collect nectar and pollen. Unlike drone bees, female worker bees have stingers which provide additional self-defense when foraging or defending the hive. Though it is true honey bees will often die after stinging a human, this is only due to our softer and fleshier skin as mammals! Less than 1% of the human population is estimated to have a severe reaction to honey bee stings – what a stingingly-low number!

 

Keeping Our Honey Sweet

National Honey Bee Day is about recognizing the problems honey bees face while honoring those who keep and manage honey bee populations. Honey bees have been crucial to the survival crops and the animals which on rely on them, including us! In fact, the first alcoholic beverage ever made – mead – is made from the honey bees produce. Honey bees are hard workers and will fly up to 6 miles to gather nectar necessary for our crops and other plants! You can learn more about honey bees and National Honey Bee Day at honeylove.org, who currently manages National Honey Bee Day! You can show appreciation for our honey bees by planting native backyards and supporting beekeepers. Have a buzzin’ bee-autiful day!

National Zookeeper Week

      Every year for one week we celebrate the amazing people that are zookeepers.  A zookeeper is defined as someone who takes care of animals in a zoo setting. This is the person who interacts with the animals daily.  This person does the daily cleaning and feeding but also does so much more than what most people realize.

      These people are the nutritionists that help create a balanced diet for the animal. They are the veterinary assistants monitoring and helping in any type of procedure or exam. A zookeeper is the artist that designs, and constructs exhibits to look as natural as possible for the animals that live in them. This person is a behavioralist checking on the animals throughout the day to ensure they are exhibiting their normal behaviors and not anything that could be harmful to themselves or another animal.  A zookeeper is a trainer, teaching the animals different behaviors to help make their lives better. An example would be standing on a scale, voluntary ultrasound, even a spin behavior so the keeper can see a full view of the animal. They are the people spreading conservation messages to help save animals from extinction. A zookeeper is the person who spends more time with the animals at the zoo than they do with their own family. For a zookeeper, the animals in their care are their family.    

      For this year, we as zookeepers would like to thank all those who support and help us to do the job that we love. This week doesn’t just belong to us, it belongs to those who help us. We would like to thank all the educators who spread the message of conservation to everyone who walks into the zoo. We would like to thank the financial department and upper management who keep the zoo running so that we are able to live out our dreams as keepers. Today, the world revolves around money and without them figuring out the budgets for feeding, enrichment, tools, and any materials we need, we would not be able to do our job. Without the marketing and sales team, no one would know our little zoo exists. Guests would not be able to walk around with their favorite animal as a stuffed toy or represent the zoo by purchasing a t-shirt with our logo.  Without the Guest Service staff, guest would not be able to enjoy their time at the zoo without a clean environment. They would not be able to purchase food or drinks during their day.

      This is a true symbiotic relationship. Without these amazing people, I wouldn’t be able to do my job. I wouldn’t be able to care for the health and well-being of so many animals. Because of these people I am able to live out my passion and my life’s work.
