\"f\u00e5gel<\/p>\n

Jag hittade en forskningsrapport d\u00e4r n\u00e5gra forskare i USA f\u00f6rs\u00f6kt att ta reda p\u00e5 varf\u00f6r f\u00e5gels\u00e5ng l\u00e5ter annorlunda i st\u00e4derna \u00e4n i landsbygdsomr\u00e5den. F\u00e5glar tenderar till exempel att sjunga p\u00e5 en h\u00f6gre tonh\u00f6jd i stan eftersom h\u00f6gre frekvenser l\u00e4ttare h\u00f6rs \u00f6ver trafikbullret.<\/p>\n

Men det \u00e4r nog inte bara bullret som p\u00e5verkar f\u00e5gels\u00e5ngen i stan, t\u00e4nkte forskarna, och spelade in 66 manliga r\u00f6da kardinalf\u00e5glar i 9 olika skogsomr\u00e5den. En del l\u00e5g mitt i staden, andra l\u00e5ngt ute p\u00e5 landet och n\u00e5gra i blandomr\u00e5den. <\/p>\n

men \u00e4n s\u00e5 l\u00e4nge \u00e4r det f\u00e5 studier som unders\u00f6kt vilka andra milj\u00f6funktioner som p\u00e5verkar f\u00e5glarnas s\u00e4tt att sjunga.<\/p>\n

H\u00e4r finns mer om den studien. <\/a> <\/p>\n

Resultatet blev att f\u00e5glarna sjunger annorlunda, beroende p\u00e5 hur m\u00e5nga andra f\u00e5glar som var i n\u00e4rheten. Sm\u00e5f\u00e5glar i tr\u00e5nga stadsmilj\u00f6er m\u00e5ste f\u00f6rsvara sina revir mot fler potentiella inkr\u00e4ktare, och detta f\u00e5r dem att sjunga b\u00e5de l\u00e4ngre och snabbare.<\/p>\n

Detta g\u00e5r naturligtvis att \u00f6verf\u00f6ra p\u00e5 m\u00e4nniskor, som alla djurforskning. S\u00e5 nu vet jag varf\u00f6r vissa m\u00e4nniskor talar fortare, l\u00e4ngre och med ljusare r\u00f6ster, \u00e4n andra. De bor f\u00f6r centralt, f\u00f6r tr\u00e5ngt och m\u00e5ste h\u00f6ja sina r\u00f6ster f\u00f6r att bevaka reviret. Detta \u00e4r speciellt vanligt f\u00f6r en del som pratar i mobiltelefon p\u00e5 t-bana och pendelt\u00e5g samt fjortisar p\u00e5 v\u00e4g hem fr\u00e5n n\u00e5got event. <\/p>\n","protected":false},"excerpt":{"rendered":"
