Sound like the birds are experiencing some of the samething we see here on clutch bbs sometimes. Link Runway Scarecrow Machine Lost in Translation Wed Mar 23,10:24 AM ET Oddly Enough - Reuters BEIJING (Reuters) - China imported a U.S.-made scream machine to scare away the birds at Beijing airport -- except they didn't recognize the noises and refused to budge. The bird-dispersing equipment had recorded the screams of American birds or the sounds of the birds' natural enemies, the Beijing Evening News said. "Local birds did not understand the foreign language," the newspaper said. So Chinese experts "translated" the U.S. bird noises into those of their Chinese counterparts. "The workers have already recorded six or seven bird screams which are common in Beijing," it said, adding that the new scare tactics were undergoing tests.
