Dig some earth and a resident robin might come close to see what food you\u2019ve uncovered. Robin-to-robin interactions are often less amicable. Strongly territorial, a robin will sing, posture by puffing its red chest and \u2013 if necessary \u2013 fight to hold its ground. <\/p>\n\n<p class=\"article-full-body sans-serif\">Researchers from Anglia Ruskin University and Ko\u00e7 University in Turkey used a robin model and recordings of songs to measure aggression between territorial robins and intruders in rural and urban settings, reports <em>Behavioral <\/em><em>Ecology <\/em><em>and <\/em><em>Sociobiology. <\/em>This showed that urban robins are typically more aggressive than rural ones. <\/p>\n\n<p class=\"article-full-body sans-serif\">Adding traffic sounds to the mix made urban robins reduce their call rate and didn\u2019t affect their aggro, but rural robins became more quarrelsome. <\/p>\n\n<p class=\"article-full-body sans-serif\">The researchers suspect that urban robins have learned to dial down their threat displays during temporary increases in noise, whereas rural robins compensate with increased aggression. Lead author \u00c7a\u011fla \u00d6nsal says, \u201cSignals are extremely useful because they can deter an intruder without a fight that may be costly to both the territory owner and the intruder, but if the songs can\u2019t be heard by the intruder the robins may have to resort to physical aggression.\u201d <\/p>\n\n<p class=\"sans-serif article-byline\"><strong>Kenny Taylor
