A new study sheds light on the significance of the so-called nest relief process, where the birds preen each other after one parent&#8217;s return from foraging duty. According to the study, this time is used by the murres to check in with their mate: if the mate&#8217;s energy and body mass is running low, they stay on brooding duty for a longer period of time, since it&#8217;s a smaller energy investment than fishing. These findings are among the first to analyse how communication\u2014not evolutionary tradeoffs\u2014affect bird pair cooperation.<\/p>\n<p><strong>Authors:<\/strong><\/p>\n<p>Linda S.
