The most fascinating thing about watching Bebe and Flash Bare-eyed Cockatoo raise their chick, Star, is that their behaviors change as does the growing inventory of Star’s exploratory actions. Let’s look at some examples.
The Power Struggle
In my last blog episode, I mentioned the power struggle that exists between Flash and Bebe, first over who would brood the eggs, then feed the chick, and now feed and stay near the fledgling, Star. I’ve consulted with an experienced cockatoo breeder in Australia about what is, in my eyes, unusual behavior. He could not give me an answer.
He did mention, though, that in captive breeding situations cockatoos can be quite difficult, as some males show intense aggression towards their mates before going to nest. I was aware of that conduct, having bred cockatoos myself. What I haven’t observed before is anything like this constant changing of who’s “in charge” of Star.
I’m thinking that this may be a natural behavior, distorted by captivity. In the wild, while one bird broods the egg or chick, the other would typically be out for some length of time finding food. When the far-ranging mate returns, the length of time has been such that the at-home mate is ready to leave the nest box, thus letting the returned cockatoo take over brooding duties.
In the aviary, food is conveniently only a few wing-beats away. When one mate leaves the fledgling’s side, the other swoops in to take over, regardless of whether enough time has elapsed.
This is all just conjecture on my part and may well make no sense at all. I could not find detailed descriptions of wild Bare-eyed Cockatoo nesting behavior, so this is the best explanation I can come up with at this time. If anyone has any other ideas or information regarding this behavior, please leave a comment. I would love to hear from you.
Feeding and Foraging
Star, at 13 weeks of age, is still being fed regurgitated food by her parents, so whoever is on Star-watch will feed her. When I fill up the food station, the controlling parent at the time will not allow the other admission to it.
Again, I ask “Why is this?” How does this relate to cockatoo behavior in the wild? Do paired cockatoos keep their mates from accessing food in nature? Most likely not, since there is probably food readily available elsewhere.
That there is an “argument” between Flash and Bebe over food access in the aviary is probably due to limited availability, since there has been only one feeding station. Providing only one food station in a captive environment can cause resource guarding. We may see it between two companion dogs when they are fed their dinner. We can see it in a group of horses when fed communally in a paddock. I answered my own question by providing one more feeding station and the resource guarding ceased.
Free Flying Behavior
Another change in parental behavior involves Flash and Bebe’s free flying. While the pair was brooding the chick and continuing until a few days after Star had fledged, it was typical that both birds would go out to fly when I opened their door. Off they’d go, sometimes at great length and other times just for a short stretch of the wings.
While her parents were out flying, Star would sit quietly tucked in or behind the birch tree that grows in the back of the aviary. At this time of her life she did no exploratory flying in the aviary on her own.
When I offered Bebe and Flash an opportunity to free fly one morning not too long ago, neither took me up on it. Okay, that wasn’t too unusual. What was unusual is that in the weeks following, going out to free fly wasn’t part of Flash and Bebe’s agenda.
As Star’s exploratory behaviors have increased, so too have the parents’ intense surveillance over her. In other words, as she becomes more independent, the parents’ concern about her whereabouts grows.
It seems that it should be the opposite; that is, as Star’s independence grows, so should the loosening of parental apron strings. Again, I’ve come up with another hypothesis.
Even though Star is becoming quite competent at negotiating the aviary by flight, she has not acquired adult capabilities. Her flying is not as physically robust as her parents. Even her ability to walk on a perch is not up to adult standards yet. However, she doesn’t hesitate to fly about the aviary with as much gusto as she can muster.
I compare this extra Star attention by Flash and Bebe to human parents whose baby is learning to walk. Once some competency has been achieved by the toddler, parents are more acutely aware of her movements, as she can quickly get herself into a pickle from her new walking ability. So it may be for Star’s parents, while she is in her “toddler” stage. In the wild, her new flight skills could easily lead her into dangerous situations.
Raptors are keenly aware of juvenile birds. Fledgling parrots have all the characteristics of defenseless youngsters. Fledgling vocalizations sound different from their adult parents. Their flight skills are certainly different from those of mature birds. Their size may be different. Their mannerisms may be more awkward and so on.
Raptors pick up on these youthful characteristics with ease and understand that an effortless meal is available for the taking. Hence, Flash and Bebe watch Star even more closely during this “toddler” stage of her development, even though she is safe in the aviary.
Behaviors I see displayed by Star and her parents are no doubt colored by their captive environment. However, observing Flash and Bebe raise Star is fascinating in and of itself, regardless of where it’s done.
Latest News About Ellie
Ellie continues to settle into life at Cockatoo Downs. She seems to have grown fond of having the flyers visit her while she is in her aviary on the deck. She shows excitement and watches intently as the small flock gathers around her aviary.
The flyers and Ellie eagerly take treats from me as we all hang out together. When they fly away, she calls after them, which I take as a healthy sign that she is becoming a bit more cockatoo- oriented, rather than just people-focused.
Just for Fun at Cockatoo Downs!
Alex Collins is a young man who attended our Exotic Bird Rescue workshop we held a few weeks ago. When I saw Alex work with a couple of the cockatoos at the workshop, I was impressed by his skill and demeanor around the birds. I invited him back for some one-on-one training time with me and the cockatoos.
Alex is calm and focused around the birds and pays attention to their body language. When there is a misread, he doesn’t get flustered and is ready to try again. Alex spent some time working Flash and Bebe in the aviary while Star watched from her perch. Bebe was all about Alex, but Flash, not so much. But with Alex’s calm persistence, Flash came around and was soon targeting and taking treats from him. It was a good day.
Chris Shank’s love of parrots and knowledge of animal training began several decades ago. Her professional experiences include a degree from the Exotic Animal Training and Management Program at Moorpark College in California, an internship at Busch Gardens’ parrot show, work as a dolphin trainer at Marriott’s Great America in Santa Clara and later in Hassloch, Germany.
Her love for cockatoos came after a relocation to the Philippines. Once back in the United States, she established her aviary Cockatoo Downs, where she has regularly offered training and education to parrot owners for many years now. She is an internationally-recognized expert in free flight.
