The younger chick was forced out into the heat, and died slowly.”įor this reason, the mothers often end up raising only one chick. ![]() When the parent arrived it favoured the larger chick, shading it from the sun with its wings and giving it water from its bill. ![]() “It would drive its sibling over to the side of the nest. During nesting, the adult shoebill makes awesome machine gun noises. Instead of welcoming the second chick, it’s common for the first-born to start a violent rivalry. “On several occasions the older chick attacked its younger sibling, drawing blood,” said BBC producer Alex Lanchester. The Shoebill is a large unique waterbird confined to a rather restricted set of generally extensive freshwater swamps of eastern central tropical Africa. Shoebills are mostly silent as they wait for their prey, but they produce a strange sound that is not common among birds. So, the first-born chicks are much bigger than the younger siblings. Tan with brown splotches, it's five inches wide and has sharp edges and a sharp hook on the end. They found that many of the nests had two chicks, which were often born about five days apart from each other. The shoebill is known by many names, including whale head, whale-headed stork, shoe-billed stork, and is even considered the most terrifying bird in the world. What makes the aptly named shoebill so unique is its foot-long bill that resembles a Dutch clog. Yet, one group of scientists were lucky enough to observe these young birds, and it wasn’t as heartwarming as they imagined.

The Andean condor also has a long lifespan of around 50 years in the wild and up to 80 years while in captivity, according to the Wildlife Conservation Society Peru (opens in new tab). The lunge of a shoebill for its prey is rapid and powerful. When it spots its prey, it springs into action. It often stands still for a long time and is very patient. ![]() On average, males weigh 12 pounds (5.6 kg) and females weigh 11 pounds (4.9 kg). It's generally seen either walking slowly through a marsh as it hunts or standing motionless in the water. Their length from tail to beak ranges from 39 to 55 inches (100 to 140 cm). around 15 pounds (6.8 kilograms) of carrion (dead or decaying flesh) in a single meal, according to San Diego Wildlife Alliance. Shoebills are between 43 and 55 inches (110 to 140 cm) tall. Andean condors are a species of vulture and like many vulture species, aren’t predominantly hunters and scavenge their food from dying or deceased animals. Due to their large wingspan, these birds can globe on air current with ease without expelling much energy. Along with their impressive wingspan, these birds can ascend to heights of up to 18,000 feet (5,500 meters) passing over the peaks of the Andes, according to Welsh Mountain Zoo (opens in new tab). The shoebill is by nature a solitary bird as opposed to the heron and the pelican, which are living in a colony setting. This means that captive populations are not self-sustained, and need to be replenished with wild birds if they are to be maintained. The Andean condor is the largest species of raptor on the planet and the second-largest wingspan of any bird - which spans around 10.5 feet (3.2 meters), according to the San Diego Wildlife Alliance (opens in new tab). Shoebills are highly sensitive birds, and past exports have involved high mortality during capture, transit and captivity Only two zoos have been known to produce chicks two in 2008 and one in 2009.
