Última Systematic notes on Asian birds. 44. A preliminary review of the Corvidae 16 Dickinson, E.C.; Eck, S.; Martens, J.. Certain Asian species of corvids, mainly those that have been reviewed since 1962, are discussed and attention is drawn to recommended changes in subspecific or specific status. Problem areas remain and research is suggested, some morphological, some molecular and some into voice. The rationale behind the ongoing revision of Corvus macrorhynchos is explained, but it is recommended that it be considered hypothetical and further developments awaited so that all relevant taxa can be assigned safely to species.

ABSTRACT Cyanocorax chrysops (Vieillot, 1818) and Cyanocorax cyanopogon (Wied, 1821) are widespread jays. They are considered sister species according to recent molecular phylogenies. When analyzing museum specimens of both species, we found two individuals with intermediate plumage characteristics. They were collected near the range limits of both species, and we classified them as hybrids. Based on the sites where these specimens were found, we discuss the possible factors leading the interbreeding and compare our findings with information available in the literature. This is the first documented case of natural hybridization in jays in Brazil and the second case involving sister species within the New World jays.
