Meet the Neighbors

There are many challenges when doing a zoo show program.  Weather has to be taken into account, wind speeds compensated for, and the crowd carefully monitored to make sure no one tries to stand up during the show.  These challenges I was always prepared for; one thing I never took into account was the neighbors.

By neighbors I mean the wild (or semi-wild) birds that call the zoo home.  When our birds first move into the neighborhood in the spring they are generally ignored by the wild birds unless they end up in a tree while learning their new patterns.

The biggest problem we have when we first arrive is the peafowl.  Peafowl are not native, and are intentionally released by zoos and theme parks for their guest’s enjoyment.  The fowl quickly call wherever they are released home, and rarely wander off grounds.  Both Milwaukee County Zoo and Grant’s Farm have free ranging Peacocks and Peahens that consider the entire zoo their territory.  In the winter months they have free range of the exhibits where we keep our birds, so they are often surprised and upset when they suddenly cannot cross into “their” territory.  They wander into the theaters during practices and we have to stand guard in the weathering area (the outdoor area where we keep our birds on display) to prevent Peahens from charging our poor birds.  Peafowl may look ridiculous, but they have strong kicks and they could do a fair amount of damage to our birds, especially the Peacocks, which have spurs on their legs.  After a while the peafowl start to realize they cannot enter certain areas, but we still have to stay on guard because peafowl are not the only birds that are not pleased with our birds’ presence.

Songbirds, understandably, are not thrilled when a group of predators move into their territory--especially during breeding season.  Once songbirds have eggs in their nests they begin to display a behavior called mobbing.  They will gather in groups and dive bomb large birds of prey to “encourage” them to leave the area.  Unfortunately, these birds do not realize that our birds have little interest in them or their young—our birds get three free meals a day.

The worst offenders are the Common Grackles, black songbirds that leave nothing to chance.  I am especially bitter about them because they chased a kestrel I worked with into the woods.  Every time he tried to fly back into the theater they chased him further into the woods (don’t worry we got him back…it just took a while).

The grackles this year were especially numerous.  Diablo (a Tawny Eagle), Reese (Great Horned Owl) and Clark (Bald Eagle) got the worst of it.  Both Reese and Diablo had clouds of five to seven grackles following them throughout their patterns.  We used the grackles’ natural fear of humans to our advantage, strategically placing ourselves between them and our birds or flying our birds into the crowd.  Robins, especially juveniles, will also harass our birds--often lurking in the trees above the weathering area in wait.

The scariest case of wild bird interaction however did not involve songbirds, but a wild juvenile Cooper’s Hawk who wanted to chase our Military Macaws my first year doing shows.  Suddenly instead of two birds doing loops around the theater there were three!  Luckily we were able to call our birds down to safety and we never saw the young hawk again.

Despite all of the trouble wild birds cause, I will admit there is no better way of finding a bird that has flown off or been blown out of the theater by wind.  Just follow the sound of angry songbirds and nine times out of ten we find our bird.  Although sometimes we find wild birds of prey!

There are many challenges to face during zoo show programs, but none quite as unpredictable as the local bird population.  They can be an annoyance, an amusement and even aid you, assuming they did not cause the bird to seek shelter in a tree in the first place.  Regardless, they certainly keep us on our toes!

If you live in or are visiting the Milwaukee, Wisconsin area this summer be sure to visit the Milwaukee County Zoo, and in particular the bird show presented by the World Bird Sanctuary.
