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

– very vocal
\n– a variety of calls to be heard during migration
\n– during spring migration AD birds utter several calls related to courtship and breeding too
\n– AD flight call is 0.3-0.4 sec in length, slightly downslurred<\/em>, screechy
\n– the AD flight call is similar to ‘KIRR’ calls (breeding grounds) but lack voice break<\/em> and harsh terminal elements<\/em>
\n– during spring migration AD F begging calls are not uncommon
\n– AD F begging calls are similar to 1CY ‘KIT’ calls and often uttered in long, fast, regular series
\n– most common call of 1CY birds in autumn is a 0.05sec long overslurred<\/em> quite variable ‘KIT’, often uttered in long but mostly irregular series
\n– 1CY birds regularly utter begging calls during migration too, often in short fast series
\n– most calls are distinctly higher pitched than similar Common Tern<\/a> calls<\/p>\nhttps:\/\/birds-in-flight.net\/wp-content\/uploads\/2017\/02\/BIF0103-1_PFR04084_1-11_100806_BIO_atern-AD-FC-JUV-BC_geez_mv-hydrogr_MS.mp3<\/a><\/audio>\n
