The night\u2010migratory black\u2010headed bunting (\n                    <jats:italic>Emberiza melanocephala<\/jats:italic>\n                    ) is day active under short photoperiods (8 h light: 16 h dark, short day sensitive). Under long photoperiods (16 h light:8 h dark), the buntings are initially day active (long day premigratory) but subsequently become intensely night active (long day migratory) and after few weeks again return to a day active pattern (long day refractory). However, it is unclear how the daily expression of circadian genes changes during photoperiod\u2010induced seasonal life\u2010history states (LHSs). We measured period 2 (\n                    <jats:italic>Per2<\/jats:italic>\n                    ), cryptochrome 1 (\n                    <jats:italic>Cry1<\/jats:italic>\n                    ), brain and muscle arnt\u2010like protein 1 (\n                    <jats:italic>Bmal1<\/jats:italic>\n                    ), and circadian locomotor output cycles kaput (\n                    <jats:italic>Clock<\/jats:italic>\n                    ) mRNA expressions in various neural and peripheral tissues of buntings in different LHSs and discovered differences of \u223c2 to 6 h in the phase and 2\u2010 to 4\u2010fold in amplitude of circadian oscillations of\n                    <jats:italic>Per2, Cry1<\/jats:italic>\n                    , and\n                    <jats:italic>Bmal1<\/jats:italic>\n                    between photoperiod\u2010induced LHSs. Phase relationship in mRNA oscillations was altered between oscillator components in the circadian pacemaker system (retina, pineal, hypothalamus) as well as in the peripheral (liver, muscle) tissues. These results show for the first time altered waveforms of clock gene expressions in all tissues in parallel with behavioral shifts and suggest the involvement of circadian system in photoperiod induction of seasonal LHSs in a migratory species.\u2014Singh, D., Trivedi, A.
