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

– most common on migration are single or fast series of dissimilar elements<\/em>
\n– calls usually consist of noise parts and slightly modulated elements with harmonic partials<\/em>
\n– clear, screechy or scratchy impression – depending on the length and quality of the calls
\n– series of calls may resemble Dunlin<\/a> or Curlew Sandpiper<\/a> – especially at greater distance or under bad acoustic circumstances<\/p>\nhttps:\/\/birds-in-flight.net\/wp-content\/uploads\/2019\/03\/BIF2870-1_PFR10840-2_0-00_150406_BIO_eoyscat-ostralegus-FL-FC_psandp-4-EC_d_sh_cuxh_kugelbake_MS_C_D.mp3<\/a><\/audio>\n
