![]() There is a certain amount of variability on this characters as highlighted by Corso & Scuderi (2011), this chiefly regarding Honey Buzzard with secondary pattern as on Oriental Honey Buzzard but more occasionally viceversa. SECONDARY PATTERN: barring on secondaries is also closer to Honey Buzzard rather than to a typical OHB where there should be 3 dark bars visible (trailing edge, middle and proximal bars) with the middle one pretty well marked and visible all along the secondaries reaching the body. PRIMARY PATTERN: the barring on primary seems to be closer to the one found in Honey Buzzard ( Pernis apivorus) with in fact the inner bars closer to the coverts (“hand” base) being proximally distributed near the wrist instead of distally as in typical adult male Oriental Honey Buzzard, where the inner dark bars are better distributed along the fingered primaries, so being closer to the dark tipped “fingers”. Again, this step is very important in order to may proceed in the identification process. Again, according to the barring on remiges this bird can be aged as an adult male. This is in my opinion an intergrade between the two species, which unfortunately appear to be quite common among the birds seen in the Middle-East and C Asia."ĭark hybrid Crested x Eurasian Honey-buzzard - by Albert De JongĪndrea Corso: "This dark phase is a tough one. The primary banding suggests Crested, while the band in the secondaries does not, the tail banding is not good enough for Crested, wing-formula shows a rather long sixth finger, but the hand itself is rather narrow lacking the proportions of Crested, and so on. "This bird, an obvious male, shows in my opinion mixed/intermediate features between European and Crested Honey-buzzard. This is consistent with the opinion of Dick Forsman, who we also consulted on this bird: ID conclusion: most probably a hybrid Crested x Eurasian Honey-Buzzard" Pro Eurasian is the narrow wing, primary and secondary barring, head and general jizz, second inner bar to tail. Pro Crested, it has a long P5 and P6, a bold terminal bar to tail (but not bold enough for a male), no carpal apparently (but often appears so in dark morph apivorus). This first step is very important in order to may proceed in the identification process.Īndrea Corso: "For a male, the bird shows mixed characters of both orientalis and apivorus. Chiefly because of the secondary pattern being unmarked white and very bright with almost no barring. It's not an easy one, this chocolate brown phase.Īccording to the flight-feathers pattern (barring on remiges) the bird can be identified as an adult male. But he did wanted to say a hybrid Crested x Eurasian! To quote Andrea on this one as a quick reply on the picture sent by his Italian friends: "ibrido maschiocrestato x orientale, salutami tutti i miei amici li"Īs we are not well acquainted with Italian humor, we first thought he joked it might be a hybrid crested x oriental, which is twice the same species P.p.orientalis. Let's kick-off with the most recent spring record. Hybrid male Crested x Eurasian Honey Buzzard - on by Andrea Vezzani ![]() We asked our identification-consultant Andrea Corso to review all documented records, and present you his analysis on every photographed Crested / Oriental Honey-buzzard in Batumi! We'll start with a post on the adult males, they are supposed to be easy. Now, we might have the first one documented on spring migration! But do we? Are we absolutely sure about those well documented individuals? What are the key identification characters exactly? Can we rule out hybridization or are all Cresteds actually intermediates? And during the 5 years of standardized counting in autumn, with more eyes and better understanding of the identification of this odd-looking heavy Honey-buzzard, this number increased. With caution and only if documented or very well seen, we were able to pick-out two individuals in 2009, four in 2010, eight in 2011 and at least twelve individuals last autumn season. On our first pilot count in 2007, which lead to BRC's birth, the first Crested Honey-buzzard (also referred to as Oriental Honey-buzzard, Pernis ptilorhynchus orientalis) was recorded on migration over Batumi.
