- Specimens of the African Secretary bird(Sagittarius serpentarius), a long-legged,crested, eaglelike bird, may have been bought to the Philippines by traders.
- Sonnerat might have heard secondhand accounts of the Philippine eagle (Pithecophaga jefferyi), which was unknown in the eighteenth century.
