Regarding the behavior, the Saddle billed Stork is noted to be silent apart from bill cluttering at the nest. They fly with outstretched necks just like other storks not like the heron that is retracted. During the flight, the bill keeps dropping below the belly height which gives the bird a unique appearance to those who view it for the first time including the travelers on safari in Uganda. But for the expert birders, this enables them to easily distinguish it.
