While working at World Bird Sanctuary’s Stone Zoo bird show in Boston, I have learned to make three major distinctions indicative of raptors: excellent eyesight, strong grasping feet and a sharp, curved beak.
Steven Spielberg’s Jurassic Park has made Velociraptors famous, but what do these prehistoric “raptors” have in common with modern raptors? They certainly don’t have a curved sharp beak or grasping feet.
It turns out Velociraptors and other theropod dinosaurs with raptor in their name such as Oviraptor or Eoraptor aren’t even closely related. However they are united under the Maniraptoran clade, which means “seizing hands,” a nice parallel to extant (meaning living today) raptors’ seizing feet. They are defined as being more closely related to birds than other dinosaurs.

Dromaeosaurs, or “running lizards,” are a group of Maniraptors containing Velociraptors and other “true” prehistoric raptors defined by their large grasping hands, a stiffened tail and one large, slashing claw on each foot. Modern birds of the Aves class are the sister group to Dromaeosaurs. You can compare an artists’ rendition of an extinct raptor to our extant raptor, Diablo the Tawny eagle below.
Today we have many different raptors within Aves, which belong to different groups as well. The orders Accipitriformes, Strigiformes and Falconiformes are an example of convergent evolution and each produced unique raptor species.
Accipitriformes is the most diverse raptor order consisting of many different families of eagles, hawks, harriers, kites, osprey, the secretary bird and Old World vultures. New World vultures of the Americas are not related to Old World vultures of Africa, Europe and Asia. They have merely evolved to fulfill similar ecological niches.

New World vulture phylogenic placement has proven to be difficult with DNA evidence supporting their inclusion in both the bird orders of Accipitriformes and Ciconiiformes or storks. Old World vultures are true raptors, while New World vultures lack the strong grasping feet of raptors. You can make this comparison between Osiris the Egyptian vulture (Old World) and Baton Rouge the King vulture (New World) at our Stone Zoo bird show.

Strigiformes consist of two main families of owls; barn owls and typical owls. Owls are mostly nocturnal and are therefore more sound sensitive than other raptors. Barn owls belong to the family Tytonidae. Their face is heart-shaped and their legs are longer than that of Strigidae owls. Typical owls belong to the more varied family, Strigidae. You can see these distinctions on Riley the American Barn owl and Reese the Great Horned owl at our Stone Zoo bird show.

Naturally, Falconiformes are falcons, which are more closely related to songbirds and parrots than they are to any other raptor (believe it or not). Falcons are the speedy and agile birds of prey that use their tomial tooth at the end of their beak to break their prey’s spine. You can see the notch that is the tomial tooth on this Peregrine falcon on exhibit at Stone Zoo.

Even though extinct and extant raptors are hardly related, you can see all these fascinating predators possess many adaptations. Their unique characteristics allow for a wide variety of species to share the generally speedy seizing and grasping raptorial name in prehistoric times and up to modern day.

In the spring and early summer months, it is enjoyable to watch birds nesting and raising their young. If we’re lucky enough, we get to watch the juveniles grow from eggs into copies of their parents; however, some witness the occasional oddity: a bird feeding a chick that is clearly not its own. This is a result of nest or brood parasitism.
Male Brown-headed Cowbird (photo: Wikipedia)
Brood parasitism occurs when a parasitic species, such as the Brown-headed Cowbird (Molothrus ater), lays its eggs in another species’ nest. In this host-parasite relationship, the parasite receives all the benefit, and the host incurs all the costs. Since the parasite doesn’t have to worry about building and defending its own nest, it can put all of its energy toward producing eggs. The female of the Brown-headed Cowbird, which is considered North America’s most common brood parasite, can lay up to three dozen eggs in a single summer, none of which are raised by the Cowbirds themselves.
For the host, the cost of being parasitized can be great. The host’s own nestlings may grow more slowly due to a more competitive parasite nestling, or the host may lose its entire clutch due to nest abandonment or the destruction of the host’s eggs or hatchlings by the parasite.

One has to wonder how the host parents could not notice the presence of a parasitic egg or hatchling, but some do. Some host species are able to recognize eggs that are not their own and destroy them, but for most the distinction is difficult to make, since some nest parasites’ eggs mimic those of the host species, or the parasite’s egg is too difficult to destroy due to its size or harder shell.
If the parasite’s egg is not destroyed, it usually hatches before the host’s own eggs. Shorter incubation times insure that the parasite grows more quickly to gain advantage over the other nestlings. Even at this stage, it is possible for some species to recognize a chick that is not their own and discriminate against it; however, the vocalizations of the parasitic nestling can actually stimulate higher rates of feeding from the host parents, enabling it to out-compete the host nestlings.
Brood parasites can be dangerous to bird species that are already in decline. It is for this reason that entrance size of nest boxes is so important. For cavity-nesting species like Eastern Bluebirds, keeping the opening to the box at a specific size decreases the odds that a parasite like the Brown-headed Cowbird will be able to fit into the box and lay its egg in the nest.

A Bluebird house can provide hours of enjoyment in your backyard.
However, bluebirds can be picky when it comes to settling into a new home. They can also become victims of predators if their nesting places are easily accessible. If you wish to hang a new home for the Bluebirds in your yard, here are some helpful tips to successfully attract a Bluebird family.

Bluebirds enjoy open areas, so choose an area that is at least 200 feet away from heavy woods. However, 1 or 2 trees located within 50 feet of the Bluebird house will be useful for your Bluebird family. This will help fledglings go from tree to tree during their first flights. Try to hang the house near locations where you know Bluebirds enjoy perching. This includes fence and telephone wires and posts.
Attempt to hang the house on a smooth metal post. This will keep predators, such as snakes and raccoons from climbing up to invade the Bluebird’s home. A good rule of thumb is to hang the house 5 to 15 feet up from the ground. Hang the house so that it is facing an area with short grass that is frequently mowed. This will help the bluebirds find food around this area, such as crickets and spiders.
If you choose to provide food for your new family, you will want to consider a few options. Bluebirds are capable of learning to eat from feeders, but prefer mealworms and berries to traditional bird seed. Mealworms can be obtained through pet stores, bait shops, and feed stores.
Hanging a Bluebird house can be a fun and educating experience. Watching a new family settle and grow in your own yard can provide more entertainment than any piece of digital equipment. Enjoy your new friends!

The water you drink . . . .it is full of stuff, even when you drink filtered water -- and that is a good thing!
The water that you bathe with, the stuff that comes out of the tap, the stuff that was deemed ‘safe’ by the local water company for you to drink, is full of stuff, too -- and that’s a good thing!
Dissolved oxygen .jpg
The water that we call ‘rain’….it may have traveled thousands of miles from the ocean where it was picked up. It may have floated over many hundreds of smoke stacks before it landed in our gardens and is also full of stuff, but this “stuff” may not always be a good thing if it has turned into acid rain. Chances are, the rain also picked up a bunch of other stuff like soil and particulates, and that is usually a good thing!
Yes, the first thing that comes to mind is that water -- that clear, effervescent, necessary ‘gold’ that, unfortunately, we take for granted -- is usually full of stuff like minerals and microscopic life that is needed to keep us humans and other critters alive.
Water, even purified and bottled water, is full of dissolved minerals, necessary for us humans to take in for all of our nutrients. These minerals occasionally add flavor to the water when you taste extra iron or calcium. And it might scare us modern humans to think that we are swallowing microbes, afraid that they could make us sick when, occasionally, these microbes DO make us sick. Who knows what else was in that innocent-looking, plain, colorless glass of water that went so far to keep us alive, that satisfied our thirst, that got brewed into that delicious cup of java in the morning?
Most of us who took chemistry class in high school learned that the formula of “ H2O ” was supposed to represent water -- 2 atoms of Hydrogen was bound together with one atom of Oxygen. Most of us were taught about the chemical bonding, the chemical ‘attraction’ between these atoms, which always set up this wonderful ratio. But if this was all that was ever in the water we drink, it would not be enough to help sustain life.

Now, most of us are well aware that chemicals, minerals, soil, and all kinds of stuff can be dissolved into that water and that we need all that stuff to stay healthy. Most of us have learned that fish can filter the life-giving oxygen out of the water across their gills as their version of ‘breathing.’ Most of us have learned that aquatic plants even pull oxygen out of the water to make the simple sugars that keep the plants alive, the microscopic organisms, the next level of creatures, etc., all the way up the predator chain.
But sometimes, it is not so much what was in that mouthful of wet that you just swallowed. A large part of this story is about what it wasn’t.
What happens when you don’t have enough dissolved oxygen in the water? Yes, unfortunately, you can have a whole pond or other large body of water -- all wet and wonderfully cool and surprisingly dead -- that is lacking in enough oxygen in the water. It is a condition called ‘Low Dissolved Oxygen. It is a rather dangerous condition too, causing massive fish kills or unwanted algae growth and other out-of-balance conditions to the environment that affects both plant and animal life, both upstream and downstream, of the body of affected water.
Dorothy Falls, Lake Kaniere, South Island, New Zealand…falls such as this help to introduce extra oxygen into the downstream water (photo: Gay Schroer)
The ‘dissolved oxygen’ that we need in water is actually extra oxygen free floating in the water and it has a separate chemical symbol, shown as “ O2“. It is a chemical bond between two oxygen atoms, bound only to each other and not to any hydrogen atoms. It is this ‘dissolved oxygen’ that the microbes, plants, and fish grab out of the water to perform their bodily functions. The “ O2“ molecules (more than one atom) get put into the water by a variety of mechanisms: most generally from the photosynthesis of plants releasing leftover oxygen into the water; bubbling and babbling brooks add extra oxygen from the turbulence, and even rain and lightening will help add extra oxygen back into the water.
We humans, particularly the environmentalists and engineers, have learned that there is a measurable quantity of “ O2“ that must be present in the water in order for it to be considered healthy. If the amount of oxygen is too low in the water, then the plants can’t fully take up the soil’s nutrients, the microbes won’t process the chemicals, and the fish will suffocate.
Ultimately, we all know what that means -- no fish, no raptors and many other birds.
Check back with us next month when we have to start putting the oxygen back into the water......

Did you know that the World Bird Sanctuary has a Junior Volunteer program? Some of our best and most valued volunteers began volunteering as a “Junior” volunteer.
Shayne Sifford, for instance, began as a “Junior volunteer” back in February 2012. Junior volunteers are not allowed to handle the Birds Of Prey. However, Shayne and all junior volunteers are able to handle many of our mammals and reptiles during Junior Volunteer years.

Once a Junior Volunteer reaches the magic age of 16, and has been volunteering for over 40 hours, they are eligible to begin handling the Birds Of Prey on a case-by-case basis. Much of it depends on the person’s understanding of how their body movements and actions affect a bird behaviorally. If a person is calm and can read the bird’s behavior then progress can be made.
Shayne began handling Birds Of Prey under the close supervision of staff members. The pictures of Shayne with Oliver the Eastern Screech Owl, shows how much Shayne has advanced. I love Shayne and his big heart. I am glad to see this young man make such great progress.
Shayne is now 18 and will be a Senior at Lindbergh High School in August 2015. His enthusiasm and strong work ethic never ceases to make me smile.
If you are between the ages of 13 and 16 you, too, can be a Junior Volunteer! If you are 16 or older you can become a full-fledged volunteer eligible to handle birds of prey. No prior experience with birds is necessary. All training will be provided under the close supervision of our experienced staff.
If you are interested in volunteering, go to our website and fill out the junior volunteer application and then be ready to attend our once per month Volunteer Orientation.

The arrival of summer at the World Bird Sanctuary can mean only one thing--zoo shows are here! And by Zoo Shows I of course mean those educational and entertaining programs WBS staff and birds present at zoos around the nation.
With every new zoo show season we have a new class of rookies ready to make their mark. This year is an especially large graduating class so to speak, because not only do we have brand new birds, but an old pro that has come out of retirement.
Zeus, a young Golden Eagle is one of our new fliers (photo: Gay Schroer)
This year we have one rookie flyer at our Stone Zoo show and five at the Milwaukee County Zoo, plus one returning flyer after a six year vacation. It is always exciting teaching new birds to fly. Most new flyers do what I like to call “prong horning,” where they hop straight up into the air and then make a horizontal flight. This is very common the first several times they take off until they learn how to better control their flights. Many new fliers also overshoot their landing spots, since they have not yet learned how to apply their brakes or to properly calculate distance. Discerning the distance to and from a perch and other objects is a skill that birds obtain through practice.
When we first started practicing Zeus our Golden Eagle he would fly away from his stumps if they appeared to be too close to the bleachers. We moved the stumps and over several days and flying sessions we gradually pushed them back to their original positions. Now Zeus loves his stumps wherever we place them on stage.
Technically this is Evita's debut year (photo: Flannery O'brien)
Even birds that don’t do a whole lot of flying, like Evita the Red-legged Seriema, have to start out slow so that they can get used to new situations. Technically Evita was in two shows at the very end of the season last year, but this year is her big debut season. We started out slowly, gradually leading her closer and closer to the stage. Her first time on the stage she wandered around for five minutes exploring everything the theater had to offer. After carefully checking out all three sets of bleachers she was ready to exit and hasn’t really wandered since.
The key with rookies is to start small, get the birds used to the behavior or pattern first and then transition it to the theater. The audience must be built up gradually until they are used to people. They often need time to check out their new surroundings, either by wandering or sitting on a high perch and just scoping out the area. Giving a bird time to do this is very important because it makes them feel safe. They learn the surrounding area, determine that there are no predators and make a mental map so they can get back in case they ever leave the theater.

Sherlock an African Pied Crow is currently practicing his recycling routine in his enclosure, but soon we will be able to practice him in the theater. Chique (a Blue-fronted Amazon parrot) is just starting to do her vocal cues on the hand rather than in her cage. Once she is comfortable on the hand, she will also move to the stage.
Azizi the White-bellied Stork rounds out our rookie line-up (photo: Flannery O'Brien)
Our last MCZ rookie is Azizi the White-bellied Stork. He is learning to follow us, and our trail of meat, wherever we go. This includes short walks outside of both his indoor and outdoor enclosures.
Skinner the Turkey Vulture is our returning veteran (photo: Flannery O'Brien)
The returning champion is Skinner the Turkey Vulture, who has already proved he is an excellent homing vulture.
Every new zoo show season means a new crop of rookies. Be sure to visit the Milwaukee County Zoo this summer and see Zeus, Azizi, Evita, Sherlock, Chique and Skinner. Also be sure to pay a visit to Roderigo the Common Buzzard up in Boston. Come see all of their hard work pay off.

They say time flies when you are having fun. This year, I am having more fun than ever working at the World Bird Sanctuary’s Milwaukee County Zoo Bird Show.
Duncan, the Wedge-tailed Eagle executes a beautiful flight (photo: Flannery O'Brien)
However, the birds and time are not the only things that are flying at the bird show. Blood. Guts. Poo. Slobber. All of these things are constantly soaring around those of us who work these amazing programs. Unfortunately, sometimes these soaring pieces of “gunk” find their way onto our arms, face, and even into our mouths.
I like to talk--a lot! (photo: Ian Wright)
I like to talk; a lot. It’s kind of my thing. My job sort of requires that I talk constantly and nine times out of ten my sentences seem perfectly timed for my mouth to be open just as the bird is sending a slobber, blood, or meat filled shower my way. I can talk my way through a lot of unexpected situations, such as a bird deciding it wants to take the scenic route to its perch. However, when an unwanted bird shower ends up in my mouth, it’s impossible to not be taken aback for a few seconds.
Whiskey Sam Adams, our African Augur Buzzard (photo: Flannery O'Brien)
Earlier this year, our African Augur Buzzard, Whiskey Sam, decided to become a part of the Africa section of the zoo by hanging out in a tree within the Bongo exhibit. After running out of my long list of “Fun Fowl Facts with Flannery,” I decided to ask the audience for questions. Of course, the first hand into the air was a little girl in the front row. She obviously had been itching to ask me the question for a while. I called on her and she eagerly opened her mouth and asked, “What would happen if a baby was crying and a bird flew over and pooped in that baby’s mouth?”
I love kid questions. They are so creative. However this was by far the most creative and unexpected question I have ever been asked. After hesitating for a moment and rewording the question so everyone could hear, I came up with the only answer I could think of, “Well, the mom would probably run to the bathroom and rinse that baby’s mouth out.”
At the time, that was probably the worst scenario I could have imagined happening with flying bird “gunk.” Until, that is, a couple of weeks later. At the end of the show, as I am delivering a particularly delightful conclusion, Clark, our Bald Eagle, decided that the piece of meat he was in the middle of consuming, needed to be shared. He shook his head and sent a shower of slobbery, disgusting, gooey meat directly towards my face and into my mouth!
All was going well until Clark decided to "share" (photo: Ian Wright)
As mentioned earlier, I can usually pretend the situation never happened and keep talking--but a piece of meat flying into my mouth was not a situation I can handle with much grace. Instantly, I started sputtering, trying to get the gunk out, but to no avail. The only thing that resulted was that the speakers were echoing my sputtering into the stands, and that was not professional. My left hand was in a glove that Clark was seated on top of, and my right was covered in blood and gore from handling food for the rest of the birds. So I did the only thing I could do. I took a deep breathe, thought, “Yep, I’m doing this,” swallowed as best I could, and continued with the rest of the conclusion. The second that show was over, and I had joked with several people about being more patriotic now that the Bald Eagle had given me that deliciously disgusting piece of food, I gracefully put Clark down, and did exactly what I had told the little girl. I ran to the sink and rinsed my mouth profusely with water.
When you work with animals, you sign up for the fun things like speaking shows and watching a bird problem-solve on its own. You also sign up for the not so fun stuff, like scrubbing poo and apparently sometimes sharing their dinners. It was easily the most disgusting experience of my life, but that was the moment I knew that I was hooked on this career and that I found where I belong. Because if I can suck it up, eat a ball of slobber and gore, and still keep a smile on my face, I can do anything that this job throws at me. Literally.

As most of you may know, the World Bird Sanctuary, in conjunction with Ameren Missouri and the Missouri Department of Conservation, has monitored a Peregrine Falcon nest box from first egg laid to fledging of the young birds.
Securely located 168 ft. above the ground on the Ameren Missouri Sioux Energy Center scrubber stack, the nest box was constructed with a design from the World Bird Sanctuary. Personnel at the Ameren Missouri facility operated and maintained a live view camera that allowed viewers to watch the fascinating behaviors of these amazing birds.
Our Falcon family has now set flight. The live camera stream was viewed more than 80,000 times and peaked at nearly 2,000 views per day in early April and May when the eggs were laid and the chicks hatched.
One of the behaviors you did not see on the live view camera was the behavior of the parents when we banded the babies. Staff member Trina Whitener captured that behavior for us and it may be viewed Here. If you have a problem viewing the video by clicking on the link, just copy and paste the following link into your browser window.

There are many ways of attracting songbirds into one’s backyard.
An easy method is, of course, to put up bird feeders and watch the feeding frenzy that occurs. Bird feeders are important because they help birds get the nutrients they need to survive, especially during migrations. If you want to encourage birds to stay in your backyard, though, you might consider putting up birdhouses, or nest boxes.

Birds that nest in boxes or other such hollows are called cavity nesters, meaning they nest in tree hollows or other such spaces that have already been created. There are quite a few cavity nesting species in Missouri; our state bird, the Eastern Bluebird, is among them.
Now, you could put up any old birdhouse and see what decides to nest there, but some species are pickier than others. The Eastern Bluebird, for example, much prefers something akin to a box on a post than a box hanging from a tree. Carolina and House Wrens will nest in just about anything.
Another determining factor for a nesting pair of songbirds is location, location, location. Eastern Bluebirds can be especially picky about this. They prefer edge-like habitats – grassy areas with a few trees. Golf courses seem to be great places to attract nesting bluebirds.
The size of the box will also determine what type of bird you attract. Possibly the most important aspect of this is the size of the opening to the box. It must be large enough to admit the bird, but small enough to deter larger competitors, nest parasites (Brown-headed Cowbirds), or would-be predators.
If you want to attract smaller birds, like wrens and chickadees, the opening should be approximately one and one quarter inches in diameter. For slightly larger songbirds, such as bluebirds, the opening should measure about an inch and a half across.
Woodpeckers are also cavity nesters (photo: Gay Schroer)
Certain birds of prey are also cavity nesters, such as the Eastern Screech Owl and American Kestrel. To encourage these birds to nest near your yard, you’ll need a larger nest box, with an opening of three inches in diameter.
If attracting a certain species of bird to nest in your yard is your goal, it is important to do your research first, remembering that the type and size of the box as well as its location can be important to nesting pairs.
Not handy enough to build your own nestbox? To begin your career as a “birdy landlord” stop by the World Bird Sanctuary’s Wildlife Hospital where we have nestboxes available for purchase at a minimal cost.

This year there is one bird that I hear everywhere, but I don’t see it. Not once have I seen this bird! As soon as I hear it I start looking everywhere! I probably look like a crazy person, but I don’t care.
In my defense, every time that I hear this elusive bird I am caught without my binoculars. I’m usually at work with the World Bird Sanctuary show and display at Grant’s Farm, holding an eagle for the family photo opportunity that we are a part of this year. Often times I’m busy getting the display area all spiffed up for the day or getting ready for show time.
The Northern Parula (photo: wikipedia)
But, I digress. The point is that I hear these birds singing all day long and by golly I would love to see one! They have such a sweet little song and they’re such dapper little gals/guys. Even with binoculars, though, they would be pretty difficult to find unless you know where and what to look for.
Northern Parulas, Setophaga americana, are warblers that have a blue head and wings, a yellow chest, a white belly, and a green back. You would think that they would be pretty easy to find with all those pretty colors, but the blue and yellow are great colors for camouflage. The colors help to break up the outline of the bird’s body so that it might look like a leaf blowing in the breeze while the sun shines on it. It’s helpful if you can zero in on its location while it’s singing. Their vocalization sounds kind of like an ascending buzz. Personally, I think it sounds like a zipper.
The reason I have such a hard time finding them, next to lack of binoculars, is that they prefer to sing in the upper canopy where all those moving leaves block my view from the ground. In mature forests near streams and swamps they can choose from the many insects that also rely on a water source to survive. When insects are sparse they will feed on available seeds and berries. It would really be a treat to view an active nest made from hanging moss and lichen, which are especially helpful for nesting.
I feel confident that I will eventually see one this summer, but let my mistakes be a lesson for birding. Never leave the house without your binoculars.
