\nPallid Swift Apus p. pallidus<\/em>, 2CY<\/strong>
\nBIF0580, 11\/02\/2015, Sur, Oman, Mathias Putze

\n– in good lighting the overall colour is greyish to milky brown (not sooty as in Common Swift<\/a>)
\n– underside appears scaly<\/p>\n

\nPallid Swift Apus p. pallidus<\/em>, 2CY<\/strong>
\nBIF0887, 11\/02\/2015, Sur, Oman, Mathias Putze
\n– contrast between darker underwing coverts and paler remiges more clinal and not as distict as in Common Swift
\n– plain head with dark \u201aeye-mask\u2018
\n– broader \u201ahips\u2018<\/p>\n

\nPallid Swift Apus p. pallidus<\/em>, 2CY<\/strong>
\nBIF0888, 11\/02\/2015, Sur, Oman, Mathias Putze
\n– before first moult all larger feathers with narrow white fringes (to lesser extend also shown by 1CY Common Swift<\/a>)<\/p>\n

\nPallid Swift Apus p. pallidus<\/em>, 2CY<\/strong>
\nBIF0889, 11\/02\/2015, Sur, Oman, Mathias Putze
\n– rather blunt wing tip
\n– darker back and lesser wing coverts slightly contrasting (can form a fairly distinct dark \u201asaddle\u2018 in AD)<\/p>\n

\nPallid Swift Apus p. pallidus<\/em>, 2CY<\/strong>
\nBIF0890, 11\/02\/2015, Sur, Oman, Mathias Putze
\n– body somewhat more robust than Common Swift but can be hard to judge in field<\/p>\n

>> ACOUSTIC ID >>>>><\/strong><\/p>\n

– most common a two-syllabled<\/em> piercing ‘scream’
\n– the first part is a sustained<\/em>, fine modulated overslur<\/em>
\n– the second part is a phrase<\/em> of fast similar vertical elements (trill)
\n– the trill is narrower spaced in males (faster)
\n– initial, peak and final frequency lower than in Common Swift<\/a><\/p>\nhttps:\/\/birds-in-flight.net\/wp-content\/uploads\/2016\/06\/BIF2877-1_PFR15288_1-11_190220_BIO_pallswift-100-M-F-FC_isr_metzoke-dragot_MP6_REF-S_C-E.mp3<\/a><\/audio>\n
