But Bats Can Fly, Too…

“How’s your climbing skills?”

With a sturdy stick, a microphone, and electrical tape on hand, the self-proclaimed bat lover, Kody Wallace, prodded me to scramble the trellis of the Chase Mill. Next to me, I could hear the chuckle of my colleagues in the Conservation Science Program, ecologists Cooper Farr and Bryant Olsen, as they patiently waited for me to accept the challenge ahead: strap a recording device to a high-up, open—yet subtle—place. Despite the pain of rock climbing the day prior still pounding through every conceivable muscle in my hands and back, Kody’s keenness and endless energy motivated me to ramp up for the task. Fortunately, a quick observation of the taller height of my co-worker, Suryaveer Singh, saved my sore fingers from ascending the wall. At a cool 6-feet, he was deemed capable of raising the microphone a suitable distance from the ground for attaching the stick to the Mill.

What in Darwin’s name were we doing? We were setting up a bat monitor! This is a device that kind of looks like a large radio with a microphone attached to it. The microphone is connected via a long cable, allowing us to strap the microphone, using electrical tape, onto the end of a stick to point it toward the sky and into open air where we expect bats to fly. The recorder itself (the “large radio”) is safely stored inside a weatherproof cargo box. Once it is turned on, the recorder does what it does best: listen for high-pitched sound.


The bat monitor is programmed to record bat calls between 7:45pm in the evening and 7:15am in the morning because this is when bats are feeding.

As non-technical a stick and tape sounds, these are essential tools to take advantage of a powerful advancement in acoustic technology. Bat monitors are sensitive enough to take advantage of the noisy nature of bats by recording their echolocation. This is a special adaptation that allows bats to “see” their surroundings. They will produce a high-pitched sound—either a call or a click—and then listen for the echo. The bat monitor records these calls and allows us to translate them into “echolocation signatures.” This is akin to written language in that we can see the shape of the waveforms produced by their sounds. Each bat species has a unique echolocation signature, just how humans all have a unique tone to their voice. With practice, you can then play a matching game of the echolocation signature to the species of bat!

“But aren’t you an Aviary?”

A friend asked me this recently as I excitedly rambled on and on about Utah bats, Kody and her infectious passion for researching bats, and how fun it was to tinker with the monitors. My first thought was, “Hey, bats fly, too!” Although, with deeper thought, I realized that they were speaking to a broader question: why should the Aviary care about non-avian species? 

Aside from the commonality of bats being as capable of flight as many birds are, Tracy Aviary as a zoo certified by the Association of Zoos & Aquariums (AZA) is committed to conservation. This translates into: breeding programs that create assurance populations of threatened bird species, education initiatives that generate deeper understanding and appreciation for all living things, and protection of wild habitats and wildlife. All of these are tied to understanding, appreciating, and protecting not just birds, but the habitats in which they live. Doing this involves also paying attention to the other species—from microscopic invertebrates to large, charismatic animals—that live in these habitats. This is because, whether we know it or not, each species plays a critical role in the health of an ecosystem. For this reason, the Conservation Science Program conducts surveys all across the valley that takes a close look at not just what is going on with Utah’s wild birds, but also the status of mammals of conservation concern, such as the western grey squirrel in the valley and pika in our mountains.


Tracy Aviary’s Conservation Science Program assesses health of local wild places and wildlife by surveying birds, mammals, and plants in select locations across the Wasatch Front.


Getting batty for bats in northern Utah

In northern Utah, we are blessed with an abundance of unique species…of conservationists! There is a plethora of organizations, community groups, and individuals that are all pushing for preservation of healthy air, lands, and water. Among these actors is Kody Wallace, a community scientist with Wild Project Utah. Petite in size, Kody carries a lot of punch for investigating seemingly simple inquiries that require tenacity to navigate the complex truths that they lead to. In just a brief conversation with her, she took me on a fifteen-year long journey of volunteering with conservation organizations like The Nature Conservancy in Utah and Wild Utah Project. By lending her skills in bat acoustics and mist netting, Kody has generously volunteered alongside biologists of various specializations to pin down where in northern Utah particular bat species roost, what happened to these roosts, where the bats went to, and how to recruit fellow bat-warriors to her cause.


Did you know that bats eat up to 1,000 insects an hour? Lucky for Utah, we have 18 species of bats to keep insects like mosquitos, midges, and mayflies at bay. Featured here is one Utah’s migratory species: the Brazilian free-tailed bat. Photo credit: Kathleen Smith on Flickr

Kody is impressive in many ways, but I’d like to re-direct the attention here to the phrase “year-round bat research.” Most people believe bats to hibernate over the winter. While this is true of some bat species, others might not hibernate at all. In fact, they do just the opposite. These bats keep it moving all year round by traveling to Utah for the spring through fall and then flying south of us for the winter. Until now, most bat research takes place while these bats are accessible to us, but little to no studies have happened during the transition period into and out of the winter, when these bats are on the move.

As it turns out, the Aviary may be a destination for these flying mammals, especially for the handful of Utah’s bats that migrate south during our winter. The Aviary itself provides trees for bats to roost, while the ponds in the Aviary and on the south end of Liberty Park serve as water sources. These bodies of water also attract the insects bats like to eat. In 2015, we set out monitors that picked up on Brazilian free-tailed bats, a migratory species that is known to travel all the way to South America in the winter. Because of this detection, Tracy Aviary was selected as a pilot site. Bat monitors are up around town in other locations, too, including at the site of one of a fellow AZA-certified institution, Utah’s Hogle Zoo.

With the support of the Wild Utah Project, the bat monitors are currently being tested at the Aviary to find the best locations for recording bat echolocation and to identify an easy-to-do method for downloading data and maintaining the monitors. Eventually, Wild Utah Project would like to open this bat research to Utahns, like you, to get as bat crazy as we are by volunteering to maintain the monitors. We are so excited to see how well the monitors detect bat calls and which species we have living at and passing by the Aviary! Stay tuned with us as we wait for updates.


The Nature Conservancy in Utah is interested in the movement of migratory bats as the move from their roosting habitats here in northern Utah (spring-fall) to their winter habitats deeper south in the US, Mexico, Central America, and South America. Stay tuned with us throughout the study as we discover more!

August was a month full of great weather, fun events and baby birds at the Aviary! Among our nestlings are some newcomers that will leave you tickled pink. If you havent heard the news already, our colorful pride of chilean flamingoes have added two new additions to their flock! On August 14, our first male flamingo was born to parents green 34 and green 38. The second chick, a female, hatched just a few days later on August 19 to parents blue 60 and green 33. Our keepers Identify the parents by the bands they wear and have been monitoring them throughout nest building and incubation process to make sure they are fit parents for the chicks. They have proven their abilities throughout the preparatory stages and even more so as the chicks have arrived, keeping very careful eyes on their babies as they explore new life in their Aviary home. The flamingo babies can be identified as well, the male being far bigger than the female. Flamingo parents are able to recognize their own chick through vocalizations, which can be observed with our flock as well.




In the first days of life, the chicks remained on their nests with parents keeping them under their wing and within eyesight at all times. Within the 1st week, however, they began walking, swimming, and exploring their exhibit, still always keeping their parents close by.  As they age, the chicks will depend on their parents’ crop milk for about the first 6 months of life, but will also begin eating foods like flamingo pellets and algae on their own within the first week. These foods provide additional nutrition to the chicks as they continue to grow... and they are growing fast! They seem to be learning everything from feeding to standing on one leg after only a few days of being born. Not to mention, they get bigger and bigger every day. 



Our unique method of raising chicks involves the benefits of them living in the flock and being tended to by their parents while also keeping them safe at night.  Every night at sunset, our keeper staff will bring the chicks inside where they are kept in a warm brooder to ensure their safety and health. The keeper then returns the chicks to their parents first thing in the morning. Once they are strong enough to walk, run and swim, as well as when they are big enough (around 1000g), they will remain outside with their flock throughtout the entire night. In the wild, flamingoes form large chick nurseries also called a “crèche” where parents will leave them for periods of time while they forage for food, so being without their flock for extended periods of time is not uncommon for flamingo chicks. 



Now that the chicks are here, we have begun the name-picking process! However, we are going to need help. Our first chick will be named by a donor who had the highest bid at our annual conservation gala, Ready to Hatch. The second flamingo chick will be named by the public through a voting process on facebook. If you have ever wanted the opportunity to name one of our birds, here is your chance! Our keepers have decided to go with an Avengers theme for our second chick, because they have done "whatever it takes" to make sure these chicks have made it here safely and happily. They even went to such measures as installing netting around the flamingo exhibit prior to their birth to keep the babies safe from a family of cooper hawks that live near by. The names they have decided on are:  





You will have the opportunity to vote on a name this Thursday, September 5th, via facebook and the names will be announced along with flamingo face paint, crafts, acitivities, bird shows and keeper talks at our Let's Flamingle celebration on September 14th!

If you haven't heard already, there is a new bird on the block. Meet the newest kea and Kea Bachelorette contestant, Ikaroa! She has been causing quite the stir as the newcomer on the scene. Whether by accident or on purpose, she has earned her place as potential competition with our other bachelorette, Scarlet (silver band).

Ikaroa (black and yellow band) was born in 2014, making her one of the oldest kea among her exhibit-mates. She was born in the same year as Gonzo (blue band) and has formed a special bond with him (at least for the time being), signaling that she may prefer a more mature mate. However, she has also been seen spending time with the leader of the pack, Arthur (orange band), so it is still a mystery as to who will find courtship with the new bird. One thing is certain, she knows how to keep them all on their toes. 



This incredible bird traveled a long way to get to her new home, coming all the way from Bomlitz, Germany at Walsrode Bird Park. She made a brief stop at the Bronx Zoo before finally finding her way to the Aviary and her new role as a kea bachelorette. She believes in staying true to who she is and where she came from. Whether or not the other kea like it, her favorite thing to listen to is German nursery rhymes. Her favorite song seems to be "wheels on the bus" and she can be seen excitedly running to the speaker whenever she hears the tune. She enjoys a good meal and is quite the foodie. Papaya, mango pits, coconut, corn and nuts are some of her favorites treats, but when it comes to water, it seems she would rather play with it than drink it. Whenever given the chance, she will dump the water bowl out the second she can. She does love baths, however, and indulges in them more and more as she gets comfortable in her new home. 



If you're interested in getting to know more about our newest kea queen and how she does in her new role on The Kea Bachelorette, be sure to tune in to the drama every Friday on facebook! Find out how she does as the new lady on the scene, who is interested in who, and who is just hungry! Be sure to spot each contestant by their special band color: Arthur (orange), Steve Austin (red), Gonzo (blue) and our lovely ladies, Scarlet (silver) and Ikaroa (black and yellow). You can also spot her and her fellow show-mates every day in person at the Expedition Kea exhibit.

Tracy Aviary's conservation department has a lot of volunteer-friendly community science programs. These opportunites are unique ways for people of every age to enjoy the outdoors while taking action toward increasing their knowledge of birds and their natural habitat. We have something for people of every commitment level, with hikes and surveys for both families and for those looking for a challenge.  Dont just take our word for it, though. This is what one volunteer had to say about her experience with Tracy Aviary's Alta Bird Monitoring Project.



This spring I volunteered for the Alta Nest Box Monitoring Project.  A training session was held at Tracy Aviary before the season started and volunteers were introduced to the importance of collecting data on nesting birds in Alta and on the history of how the project began. We learned how Tracy Aviary monitors nest boxes and how to take pictures inside owl and song bird nest boxes by using a camera attached to a paint roller extension pole. We were able to practice taking pictures inside the boxes by either placing the camera in the entrance hole of the owl box or by lifting up the top of the songbird box.  We were also taught how to use a GPS to locate the nest boxes at Alta and how data is recorded for each nest box. 

The actual nest box monitoring adventure began in March, on snowshoes and we were always accompanied by Cooper, Bryant or Lucila from the conservation department at the Aviary. I have never worn snowshoes before and it was a lot of fun, but definitely more strenuous than regular walking or hiking.  I fell down every weekend, sometimes on my face but I loved every minute of it. It was so beautiful being out in the wilderness snowshoeing to the nest boxes. I was surprised at how low the boxes were to the ground because the snow pack was so high this year and I was impressed with how knowledgeable Cooper, Bryant and Lucila were in pointing out which species we were hearing and seeing in the area while we were going to each nest box. They always answered any questions we had and I learned something new every week.  Early in the season we only monitored the owl boxes and unfortunately we had no owls nesting this year, but it may take several years for an owl to decide to nest in one of the boxes. 



It was really exciting when the song birds started nesting later in the spring. We were able to learn what the different types of nests looked like depending on the species. I saw mountain chickadees and house wrens up close along with eggs and babies in the nest boxes. It was wonderful to watch the parents actively feeding the babies and to hear them inside the nest box. I really enjoyed watching a house wren chick poke their head out of the nest box waiting for the parent to come back with food.  It was very rewarding to know there was a successful nesting attempt and to see the babies grow up and eventually leave the nest.  It was great when people hiking by stopped us to ask what we were doing and we could tell them about monitoring the nest boxes.  One individual even borrowed binoculars to look at an active nest with a house wren feeding it's babies.  It was great to share the experience with them and to watch their face light up with excitement as they watched the adult feed their young. 

Volunteering for the Alta nest box monitoring project was very gratifying and I looked forward to going every weekend.  I highly recommend this wonderful experience where you can get outside, learn about the birds at Alta, get hands on experience in nest box monitoring and work with the great people from Tracy Aviary.

47995959398_398654cc54_o.jpgReady to Hatch, Tracy Aviary's garden party for a cause was last weekend, and it did not disappoint! Through the efforts and donations of everyone that attended, we were able to raise around $105,000 to support our conservation department. Events like this help fund many of our conservation science and community science projects, which do vital work in helping the wildlife and nature in our very own backyards. Along with the amazing food, drink, bird visitors, and music, the guests were able to enjoy our beautiful gardens and great company. We are grateful to everyone who came out to support this beautiful and important evening.




47995935022_a7454bc259_o.jpgEvents like Ready to Hatch are the reason Tracy Aviary can do such great work in their feild!  With citizen/community science programs like the Breeding bird surveys, Alta bird monitoring project and Project broadtail, people of all commitment levels can help make a direct contribution to the work and research of the Tracy Aviary conservation department. While helping the Aviary in their efforts, these projects allow citizen scientists to relax and have fun as they learn all about the birds and nature of Utah. They include family friendly walks, hikes, and surveys for bird nerds of all ages and abilities. These projects extend far beyond our work at the Aviary to help native birds and their natural habitats all across the state, the country and more. Not to mention, they are a great way for people to get outside and enjoy nature while increasing their scientific understanding. 



FOA_Nuthatch.jpgCitizen Science Breeding Bird Suveys: 

In partnership with Salt Lake Public Utilities and the Utah Division of Wildlife Resources, Tracy Aviary has been conducting annual breeding bird surveys in City Creek Canyon, UT, since 2011. These surveys are conducted by people of the community along-side our conservation department to better identify and understand the native birds of Utah. While doing these Surveys, community scientiests get a chance to enjoy the great outdoors while looking for, listening for, and writing down information about the birds they find. The goal of this project is to generate science-based knowledge that helps provide the nessary tools for managers of the canyon. Over time, we hope to better understand how the amount of birds relates to the quality of the habitat they live in, and how we can use this information to support bird and habitat conservation. 


PJ_50A6252.jpgAlta Bird Monitering Survey:

This survey is for the adventurous! Tracy Aviary citizen scientists join up with our expert birders in search of the feathered friends that call Alta home. Studying the birds in that unique, high elevation habitat allows us to better understand the species that live there. Our bird list and counts are continually growing, and so is our excitement! Surveys are done in summer on breeding birds and in winter, on skis or snow shoes, for non-breeding bird species.



PBT2.jpgProject Broadtail:

Project Broadtail is a family friendly community science project that helps us better understand how to protect the Broad-tailed Hummingbird, which is a bird of conservation concern in the state of Utah. Participants have the choice to go on a easy hike or walk with our conservation team to search for and document the Broad-tailed Hummingbirds that they see around their home and in surrounding recreational areas. These surveys provide important information about Broadtail distribution patterns, habitat, and migration. They are fun, healthy, and important for the survival of a beautiful and important pollinator like the hummingbird. 


38453424592_c89b0e757f_o.jpgTracy Aviary's conservation and community science projects not only help our native natural lands, but helps in the public participation and collaboration of important research to better understand the world around us. If you are interested in getting involved with our community science program, or want to learn more about these or other Aviary projects, please visit our conservation site:

May at Tracy Aviary is full of events, news, gardens and birds... and LOTS of them! Out of all of the things the Aviary is celebrating this month, the event that has us soaring is the grand opening of our newest exhibit and family play area, Eagle Ridge! It will open to the public on May 11th as part of our Urban Bird Festival. You can see the new exhibit and play area, see the eagles, enjoy activities with community partners, do crafts and learn while exploring the birds and surrounding nature we love. To kick off the weekend-long celebration, we thought it was only fitting to introduce you to the Eagle Ridge residents: the eagles! 



Eagles of all kinds come to Aviaries and Zoos a little differently than other birds. They are a federally protected species and can only come from licensed wildlife rehabilitators. The eagles you find in captivity are only there after they have been deemed unfit to live on their own in the wild. This is usually because they can’t fly due to health issues or injury. The stories of our four beautiful eagles are no different. Tracy Aviary's male golden eagle was found as a juvenile with a break in his wing in 2002. Although it is no longer practiced by wildlife rehabilitation centers today, after failing to rehabilitate the wing, it was amputated. After that, our male golden eagle was brought to the Aviary from Emery County, UT in February, 2003 as a potential mate for our resident female. 



One of the Aviary’s oldest resident birds, our female golden eagle has been here since 1990. She is 34 years old, which is older than the standard lifespan of a golden eagle! She has lived and long and happy life here at the Aviary after being found in the Daniel’s Canyon area with a left shoulder fracture.  She has had numerous chicks with her male counterpart while living at the Aviary. Two of those chicks were lucky enough to be part of a release program, and were released back into the wild in Topeka in 2006. 



Justice, our original bald eagle was caught in Gordon, Nebraska in 2008  where she was the subject of a medical research report. She underwent rehabilitation surgery to fix her right humorous and although unsuccessful, her surgery report actually got published. She was also part of the Rocky Mountain Raptor Program in Colorado before coming to the Aviary to stay. 


  1. Screen_Shot_2019-05-10_at_12.14.10_PM.png

Last but not least, meet our newest bald eagle, Liberty. She came to the Aviary from Rowena Wildlife Clinic in Balles, Oregon. She was found with a galvanized rooting nail in her left wing and was treated for metal toxicity. Although the nail was removed, the wing never fully recovered. She made her debut at the Aviary on  and although she is still getting used to her new home, she is doing very well.

You can meet Justice, Liberty and all of our eagles at the Eagle Ridge grand opening this weekend at Urban Bird Festival. Saturday and Sunday from 10am - 3pm. Event included with price of admission. Free Admission for Head Start and Early-Head Start families during the month of May. For more information visit our webiste

It is spring time which means a very busy time for the bird care department.  It is the start of breeding season for many of the birds at Tracy Aviary!  The birds do a lot of the work on their own when it comes to courtship and chick rearing, but our Aviculture team is always working alongside them, providing everything they need for a successful breeding season.



Aviculture starts off the season by placing nest boxes for waterfowl, filling nest logs with mulch for the toucans and aracari, and tilling the flamingo breeding area in preparation for nest building.  There is always a lot to do, but these steps are essential to ensuring the birds have the appropriate “exhibit furniture” to cater to their specific needs as species. It is also important that they provide these items early in the season so the birds have the time they need to build relationships through nest building. 



It might sound odd, but insects are essential to the breeding success of most of the species here at Tracy Aviary. This is because insects provide the appropriate amount of protein to ensure proper growth of chicks.  Almost all species depend on insects during chick rearing, even if their primary diet is fruit based.  During the spring and summer months insect amounts are increased to simulate a “time of plenty”.  This gives the birds assurance that there is plenty of food available for them to raise their young.  



Some of our birds prefer the privacy of our off-exhibit holding.  We use this space to cater to sensitive species or pairs that need specific attention from our Aviculture team.  For example, our superb starlings are medicated for a naturally occurring parasite that doesn’t affect the adults, but could be detrimental to the chicks.  The parents are provided a medication that is dusted on their insects, which they deliver to the chicks during feeding time. This approach ensures the chicks will receive their medication while also allowing the parents to raise the chicks with minimal disturbance.


With all there is to do around here, our staff definitely has their days full. However, we enjoy the work we put in to making our birds and gardens as thriving as they can be each spring, and the beautiful life that comes from that hard work.
