Great Kiskadees….Pitangus sulphuratus

Most often seen in the water fall area of my forest, but sometimes close to the lodge, were the Great Kiskadees. Always in small flocks, they were noisy, gregarious birds, with attractive chocolate-brown and sulphur-yellow plumage and masked eyes, like little bandits.
These fly-catchers are monogamous. The female lays two to four eggs in a round, ball-like nest built of sticks in a tree. The nest has a side entrance.
Kiskadees eat insects, fruit, tadpoles and fish. I’ve read that Kiskadees do not hunt in flocks, but like to hunt alone or in pairs. My observations told me otherwise.
On one occasion I sat in a canoe and watched as a small flock crept along a large branch that had fallen across a stream. They were agitated and noisy, staring at a commotion in the water below them. The disturbance was caused by a pyramid of Red-bellied Piranhas, turning and twisting their glimmering bodies, as they quickly disposed of whatever had become their prey.
The kiskadees waited above this melee. They seemed to be waiting for their share of the spoils. They appeared to be communicating with each other as they became more and more excited. Wisely, but impatiently, the kiskadees waited until the piranhas had their fill before diving straight into the water, not as deeply as kingfishers, but deep enough to take whatever scraps the piranhas left behind. Only then did they calm down.
In the first photo can be seen the splashing of the Red-bellied Piranhas as they ate their prey. Behind them on the large fallen branch the Great Kiskadees waited excitedly.




Katydid insects.Tettigoniidae


Katydids. There are about two thousand species of katydids in the Amazon. They feed on flowers and fruit and are themselves a source of protein to many different kinds of animals.
Just read in Science News that Copiphora gorgonensis katydids have ears below their knees, which are smaller then a grain of rice. They have an eardrum on each leg. Its air pressure on these drums that produce vibrations, that are picked up by sensor cells which detect frequencies. They hear in a similar, but simpler way than humans. How fascinating is that.
