Yellow-billed kite
species of bird
The yellow-billed kite (Milvus aegyptius) is the Afrotropical counterpart of the black kite (Milvus migrans), of which it is most often considered a subspecies. However, DNA studies suggest that the yellow-billed kite differs significantly from black kites in the Eurasian clade, and should be considered as a separate, allopatric species.
Taxonomy
The yellow-billed kite was formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He specified that the bird was found in Egypt, placed it with the eagles, falcons and relatives in the genus Falco and coined the binomial name Falco aegyptius. Unusually, Gmelin did not cite a source for his information. The yellow-billed kite is now one of three kites placed in the genus Milvus that was introduced in 1799 by the French naturalist Bernard Germain de Lacépède.
There are two subspecies:
The yellow-billed kite was formerly considered as conspecific with the black kite (Milvus migrans). A molecular phylogenetic study published in 2005 compared DNA sequences of two mitochondrial loci of the red, black and yellow-billed kites. It found that there was significant divergence between the three species, but unexpectedly, the two clades corresponding to the M. a. aegyptius and M. a.
The public source identifies “Yellow-billed kite” as species of bird. This brief keeps that definition visible, then builds a research path around Yellow-billed, kite and species.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Yellow-billed kite”, the useful work is to connect “species of bird” to the records capable of establishing context and consequence.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Apr 16, 2026. The linked authority identifier is Q32840. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1788, 1799 and 2005.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
