Adopt a Bird Spotlight: Acorn (Eastern Screech Owl)

Acorn's Story

Species: Eastern Screech Owl (Red Phase)
Hatched: 1995

Acorn is a real crowd pleaser. Whenever he comes on stage the comment is usually, "Isn't he cute!" but don't let his looks fool you. For their size, Eastern Screech Owls are among the feircest predators in nature.

Acorn is a verteran performer and has participated in presentations at Sea World Ohio near Cleveland among other venues. He is currently a favorite of the thousands of children who meet him in schools and auditoriums during one of our Raptor Awareness or Fur Feathers and Scales programs.

Return of the bats!

Every spring we see a sudden return of the only flying mammal in the world. In North America, bats are one of our most precious and misunderstood natural resources. Not only do they feed on mosquitos and other insects, the natural ecology of cave life depends on them to provide the nutrients needed to sustain life. Here in Missouri, bats congregate in the spring to form nursery colonies, producing offspring (one to four bats, depending on the species) in May or June. The young are fed milk until they are able to forage for themselves.

Destruction of habitat, pesticides, and disturbance has contributed to the alarming decline of bats in recent years. In addition, human fear and misunderstanding of bats has contributed to their decline. Bats are in fact carriers of rabies, but transmission of the disease is very rare. Their shy nature leads them to avoid human contact. Should a bat become trapped in your house, close off the room and call your local Department of Conservation. Someone will be sent to remove the bat safely.

The truth is that we depend on bats in ways that are crucial, not only to the environment, but to the economy. Respecting their habitat and educating others on the importance of these amazing and fascinating animals is the first step toward maintaining and recovering a healthy bat population worldwide.

Here are photographs of some of the many species of bats in Missouri, courtesy of the Missouri Department of Conservation.

Adopt a Bird Spotlight: Timber (Eastern Screech Owl)

Timber's Story

Species: Eastern Screech Owl (Red Phase)
Hatched: Unknown

Timber arrived at the World Bird Sanctuary as a very young chick in 1999. He had suffered a wing injury when his tree was cut down. He was lovingly raised and trained by WBS staff members, who named him Timber because screech owls typically live in deeply wooded areas.

Even though he is very tiny (weight about 143 grams), Timber is fully grown with red plumage typical of the red phase of is species. In the summer of 1999, he began traveling with the World Bird Sanctuary's Education Department staff as a prime example of the impact that habitat destruction has on wildlife.

Your adoption donation will help to feed, house, train, and care for Timber so that he may continue to carry the message of the importance of preserving natural habitat to thousands of people each year. Adoptive parents who would like to visit Timber should call 636-861-3225 to make sure he is on site and to schedule a time for their special visit.

The Zen of Timber

When Timber, our Eastern Screech Owl, isn't working for habitat conservation, he enjoys sitting outside, contemplating his place in the universe. For such a tiny creature, screech owls have a dignity that is all their own.

Mischief Enrichment

Among our responsibilities to the birds at WBS, enrichment is one of the most exciting and important. By exploiting a bird’s natural behavior and curiosity, enrichment provides not only physical activity, but also necessary mental activity. Besides which, it is fun to watch!

Last week I decided to try a new entertainment. I brought a clean and empty milk carton from home and, with Mischief the white napped raven carefully observing my every move, placed several live meal worms inside. As you can see from the video, the project was a hit. Mischief, whose monikers include “Destroyer of Ankle,” lost all interest in me as she wrestled the milk carton into submission.

In the absence of planned enrichment, birds as intelligent as Mischief take it where they find it. Mischief, for example, has been known to enjoy the excitement provoked by a sharp nip to the human ankle or shin. And there is no amusement park ride to compare with clinging to a person’s leg as it tries to escape your fiendish grasp. For obvious reasons, this is not a behavior that we want to encourage. Keeping an eye on the behavior of our birds allows us to “listen” to their wants and needs and to respond accordingly.

As you can see, enrichment makes both birds and people very happy campers.

Hi Mischief!

There is little doubt that Mischief, our white naped raven, is appropriately named, but she is my favorite raven. Check out her sunny disposition:



If you are around St. Louis this summer and happen upon a large raven taking dollar bills from humans and placing them in a donation box, you are witnessing Mischief at work. She's good at what she does!

How Goblin grew...

As a follow-up to yesterday's Adopt a Goblin post, here are some pictures of the little guy growing up, courtesy of Gay Schroer.

Goblin at 33 days old. Look at the size of those feet!! At this age he was still being kept in an incubator most of the time to regulate his temperature.

Still 33 days, and Goblin spots his first eagle.

Goblin at 44 days old. He's learning to keep his balance, and has grown into those oversized feed. He's also beginning to get his "big boy" feathers.

Goblin at 55 days old. Here he is displaying a barn owl's natural hunting instinct as one of our Naturalists rustles a piece of paper inside the log.

Goblin at 55 days old displaying his beautiful new primary feathers.

Goblin at 65 days old. If you look very closely you may still spot some of his baby down feathers, but for all intents and purposes he now has his adult plumage and is almost indistinguishable from the adults of his species, although in the wild he would still have much to learn.

At 65 days Goblin has taken his place in the weathering area behind the Nature Center, and is ready to start his training as a member of the Office of Wildlife Learning. In the days to come he will learn to fly from trainer to trainer, just over the heads of audience members, as he does his part to educate the public about his species. When you visit the World Bird Sanctuary, be sure to look for Goblin.

Adopt a Bird Spotlight: Goblin (Barn Owl)

Goblin's Story

Species: Barn Owl
Hatched: 2/23/08

Goblin was hatched at the World Bird Sanctuary's breeding facility in Valley Park, MO. At a very young age he was given into the care of our Office of Wildlife Learning (O.W.L.) staff where he has captured the hearts of young and old alike. He is now being trained to participate in our education programs, where he will act as a spokesbird for his species.

Barn Owls are still considered endangered in Missouri, and the birds in our Education Department are one of the most effective education messengers available for this beautiful species. Goblin will soon be teaching thousands of audience members about the usefulness of Barn Owls in controlling rodent populations. Did you know that one barn owl family (5-7 birds) can consume up to 25,000 rodents in a single year? It would be a tragedy to lose this beautiful and useful species due to habitat destruction and the overuse of pesticides.

Your adoption fee will help pay for his favorite food--mouse tidbits!

Sex: both sexes similar in size and color; females usually larger, heavier, darker in color than males; females and juveniles generally more densely spotted; sexually mature at 1 year; mate for life

Age: high mortality in the first year; average age in the wild is 2 years; few adults live beyond 3-4 years; oldest recorded wild barn owl in North America was 15 years, 5 months; captive birds have a much longer lifespan

Length: 14-20” Wingspan: 3.5’ Weight: 8-21 oz.

Habitat: prefers open land, prairies, grasslands and agricultural area for hunting; nest in natural hollows in trees, cliffs, caves, nestboxes, barns and other structures

Status: legal status across the entire US as a whole is “Not Endangered”; however, legal status in many states, including Missouri, is “Endangered”; causes of mortality are: loss of nesting sites, grasslands and pastures; great horned owl predation; vehicle collisions; shooting; poisons used to kill rodents which the owls eat; other factors which affect the rodent population

Range: every continent except Antarctica

Behavior: breeding season March through October; mating and courtship involve much chasing and screaming; nest is a scrape lined with pellets and debris; not extremely territorial; may nest within ½ mile of other pairs; usually 4-6 solid white eggs, sometimes more; one egg laid every 2-3 days, but incubating starts immediately hence there may be as much as two to three weeks difference in age of chicks in same brood; generally 3-4 young survive; incubation period 29-45 days; young fledge at 7-10 weeks, but do not leave the area until 3-5 months old; may lay a second clutch of eggs when young start to leave the area; usually hunt from a perch; also known to fly low over open fields in a quartering flight pattern to locate small rodents in their runs
Diet: majority of prey is small rodents , but will also hunt birds, fish, reptiles and insects

Vocalization: does not hoot; communicates with grunts, raspy hisses and drawn out hissing screams; male’s courtship call is a shrill repetitive twittering; adults returning to a nest give a low, frog-like croak; when disturbed at the roost or nest it makes hissing and rasping noises along with snapping sounds known as bill snapping


INTERESTING FACTS ABOUT BARN OWLS


√ A barn owl family (5-7 birds) can consume 25,000 rodents a year; one pair may take as many as 1,000 mice during the nesting season alone to feed their brood

√ 200 pellets from a pair of barn owls roosting above the Smithsonian Institute Building contained 444 skulls, including 225 meadow mice, 179 house mice, 20 rats, and 20 shrews—all caught in the city

√ Can catch prey by hearing alone in total darkness due to asymmetrical location of the ears which allows them to triangulate sound

√ Because barn owls tend to live in damp areas, a fungus grows on their feathers, giving them a phosphorescent glow at night—hence the often used name “ghost owl”

√ Common nicknames: ghost owl, monkey faced owl, white owl, night owl, Sweetheart Owl, church owl,

√ Throughout history, barn owls have been associated with omens, witchcraft, and death; they were used as symbols, in myths and as part of superstitious potions

√ The female’s breast spots are believed to be a stimulus to the male, indicating the quality of the female. When a female’s spots were experimentally removed, the male fed the nestlings at a lower rate than if the spots were left alone

We never get tired of the eagle owls...

Further adventures with the tennis ball (with a little nudge from me).



Eurasian eagle owls are the largest owls in the world. They pose a significant threat to the dreaded tennis ball and work ceaselessly to rid the office of this round yellow pest. That is, when they aren't napping or eating (or napping).

Adopt A Bird spotlight: Sirrocco (Peregrine Falcon)

Sirrocco's Story

Species: Peregrine Falcon
Hatched: Unknown

Sirrocco is a captive bred bird who came to us from another facility. In 1996, he was working at Scott Air Force Base as part of the Bird Air Strike Hazard program (B.A.S.H.). This program saves many lives every year by using falcons to deter other birds from flying in the vicinity of airfields, thereby preventing midair plane/bird collisions.

That year, while chasing a dove that flew toward a chain link fence, he was unable to veer off in time and collided with the fence, breaking both wingtips. At first it was thought that he would never fly again. However, after his wings healed one of our dedicated staff membersactually taught him to fly again, and he joined the BASH group at McGuire Air Force Base in New Jersey. Unfortunately, it soon became clear tht he would never be able to manuever well enough to resume his air force career. He was returned to WBS to join our office of Wildlife Learning and began a new career as an education bird. When he's not traveling throughout the country with our education staff as an ambassador for his species, he can be found in the weathering area behind the Visitor Information Center at WBS headquarters in Valley Park, Missouri.
