In it was decided a proactive approach to training would be implemented for the birds in Wings of Wonder. The goal was to train as many birds as possible for behaviors that would facilitate husbandry and daily care. Initially several of the vulture species were identified as excellent training candidates. The criteria used to determine this was the level of comfort in close proximity to keepers and their willingness to accept food from keepers.

A female Andean Condor Vultur gryphus was involved in the training program until her transfer to another facility. The King Vultures were successfully trained to target, shift, enter a kennel, present a foot, and allow tactile to the chest.

They also bred and raised offspring and participated in training throughout the process. The offspring also learned to target and stand on a scale. Another bird that demonstrated a high level of comfort in the presence of the keepers was a female Harpy Eagle named Killa pronounced kee ya. They can weigh from ten to twenty pounds and have a six and a half foot wingspan. Their talons are comparable in size to the claws of a grizzly bear.

They feed primarily on animals that live in the trees, like sloths, monkeys, opossums, and some reptiles and birds. Harpy Eagles are highly maneuverable fliers and strike their prey after a rapid pursuit through the trees.

Hatched in an incubator, she was then hand raised using techniques to avoid imprinting on humans. While in the brooder she was covered with a towel, set behind a curtain, and a CD of rainforest sounds was used to drown out the sounds of human voices. During feeding keepers placed a sheet over their heads and used a Harpy Eagle puppet to deliver food.

For safety purposes the Dallas zoo policy requires that a keeper is only allowed to enter her enclosure if another keeper is present. However what keepers observed was a bird that appeared quite comfortable in the presence of people.

She had never been observed to present aggressive behavior. Nor did she demonstrate a fear response. This in part may be the result of her experiences as a chick with humans at the Avian Propagation Center. Other individual birds in Wings of Wonder such as the much smaller Ornate Hawk Eagle Spizaetus ornatus would show overt aggressive behavior, flying directly at keepers.

The Spectacled Owls Pulsatrix perspicillata showed extreme fear responses and escape behavior when keepers were present.

Compared to these individuals Killa appeared to be a training candidate with excellent potential.

With the permission of the curator Killa became the next training subject for the Wings of Wonder team.

However the process of grabbing and restraining a bird against its will is contradictory to the goals of a positive reinforcement training program. Furthermore knowing the weight of an animal is not necessarily important to reaching training goals.

While the information can be of interest for evaluating health, it is not required to train an animal. Instead keepers tried to ascertain based on observations, the amount of food Killa typically ate in a day. They also observed her responsiveness to food when she was relaxed and comfortable. More or less food could be added or removed from the diet based on her response during a training session to maintain an adequate level of interest in training.

This amount changed in correlation with the time of year. Colder temperatures meant an increase in diet.

Warmer weather meant a decrease. Because Killa showed a high level of comfort around people she readily took food from keepers in the first training session. Per zoo policy the food was offered from hemostats as opposed to hands.

Training was initiated with keepers outside of the enclosure. The first behavior Killa learned was to target. The target was a blue plastic circle attached to a dog clip.

The target could be hung on the outside of the cage near the eagle. At first food was held near the target. Killa learned to touch the blue target with her beak to earn the food reinforcer. In the early stages of training, the target became a useful tool to call Killa to the front of the cage for keeper talks. This offered zoo guests a great opportunity to see the impressive wingspan of a Harpy Eagle as she flew to the front of the enclosure. Plenty of time to hang around for this little sloth.

They do move, but very slowly and always at the same, almost measured, pace. Sloths are not the only creatures in the animal kingdom to adopt a slow pace. Cold-blooded ectotherms such as frogs and snakes, are commonly subject to enforced slow movement when faced with cold temperatures, due to their inability to regulate their own temperature independently of the environment.

Just like any chemical reaction, cold muscles are slow muscles so cold reptiles are slow reptiles. This is in stark contrast to most homeothermic mammals which maintain a stable, high core temperature via a process of adaptive thermogenesisand are consequently able to move fast and effectively regardless of the ambient conditions.

But this athletic ability comes at a cost: So where do sloths fit into this dichotomy?

Sloths aren't lazy – their slowness is a survival skill

They move slowly at all temperatures and, unsurprisingly, deviate from the typical homeothermic mammalian plan by operating at lower body temperatures than most mammals, while apparently having a reduced ability to thermoregulate. The average temperature of the three-toed sloth is around Both two and three-fingered sloths have a predominantly folivorous leaf-based diet, consuming material with a notably low caloric content.

There are plenty of other mammals which specialise on a leaf-based diet, but usually these animals compensate for their low-calorie diet by consuming relatively large quantities of food. Fellow leaf-eating howler monkeys move at a normal pace but consume three times as many leaves per kilogram of body mass as sloths, digesting their foodstuff comparatively quickly. Therein lies another sloth peculiarity: Sloths appear to break this rule to an unprecedented extent. The exact rate of digestion remains unclear, but current estimations for the passage of food from ingestion to excretion range from hours to a staggering 50 days 1, hours.
