(Tetrathopius ecaudatus)


The word "bateleur" is French for "street performer."

Bateleur Eagles are a medium-sized eagle, weighing 1.8 - 2.9 kilograms (4 - 6.5 pounds) and having a wingspan of 168 - 190 centimeters (about 5 - 6 feet).  They're distinctive rocking flight and low, searching passes while hunting allow for wonderful viewing in the wild.

Bateleurs are uncommon among raptors in that males and females are physically very different from each other -- something known as "sexual dimorphism."  Both sexes are mainly black with a rusty chestnut back and ashy grey wing coverts, but females also have grey secondaries with a trailing black edge.  This makes it very easy to differentiate males from females, whether they are perching or in flight.

Bateleurs are primarily silent, except when threatened or anxious.  When they do call out, their voices can be loud and carrying.

Although Bateleur Eagles have a wide range throughout Africa, their population has been falling since the 1970s.  The primary cause of their decline is believed to be deliberate poisoning by large-scale commercial farms.  Conservation actions include awareness campaigns to reduce the use of poison baits, and continued monitoring throughout the Bateleur's native ranges.
