\nlight morph
\n– moult gap in primaries typical for 2CY birds in spring
\n– light grey head and tail are the lightest parts
\n– light bases of the outer primaries diagnostic<\/p>\n

\nBIF1457, 20\/04\/2011, Sauran, Kazakhstan, Patrick Franke
\nlight morph
\n– typical long-winged silhouette

\"\"<\/a>
\nLong-legged Buzzard Buteo rufinus cirtensis<\/em>, AD<\/strong>
\nBIF1461, 27\/12\/2012, Morocco, Mathias Putze
\nlight\/intermediate morph
\n– unmarked fox-red tail with slim subterminal band
\n– scaly pale fringed lesser and median coverts contrasting to uniform dark greater and primary coverts

\"\"<\/a>
\nLong-legged Buzzard Buteo rufinus cirtensis<\/em>, AD<\/strong>
\nBIF1462, 27\/12\/2012, Morocco, Mathias Putze
\nsame as BIF1461
\n– less distinct dark carpal patch as in ssp. rufinus
\n<\/em>– aged by plain tail and wings with distinct broad dark trailing edge and very fine barring
\n– wings held in slight ‘V’ when soaring<\/p>\n

\nBIF1463, 27\/12\/2012, Morocco, Mathias Putze
\nsame as BIF1461
\n– note contrast in remiges from broad dark trailing edge to fine bars
\n– outer primaries without barring (-> Common Buzzard<\/a>)
\n– slightly different proportions than ssp. rufinus<\/em> (e.g. shorter winged)<\/p>\n

\nLong-legged Buzzard Buteo r. rufinus<\/em>, AD<\/strong>
\nBIF1450, 27\/01\/2015, Quba, Azerbaijan, Michael Hei\u00df
\ndark rufous morph
\n– dark iris
\n– pale primary patch (more distinct than in ssp. rufinus<\/em>)
