|There is disagreement about the status of this species. HBW, Howard & Moore, the SACC/AOU and Ferguson-Lees give it species status though Ferguson-Lees gives it the English name of Gurney's Hawk which doesn't seem to be used by any other authority.

There is also an SACC proposal to make the two conspecific.|

wings and was found at higher elevations. However, it now seems that these
differences are clinal or gradual. The fact that vocalisations are the
same also adds to the case for treating the two as a single
There are certainly wide variations in plumage. Photo 1 shows a small portion of the rufous mantle found on many females.
