\u201cOur \u2018resident\u2019 male Large-tailed Nightjar (Caprimulgus macrurus bimaculatus<\/em>) has been with us for more than 4 weeks and my wife has affectionately named him ‘Clockwork’ in line with his fixed routines. It has been wonderful to show this bird to \u2018non-birdwatching\u2019 visitors who visit our home; all have been amazed that such birds exist (more budding bird watchers in the making). We have now extensive observations and would like to share a few.<\/p>\n <\/a><\/p>\n \u201cGular fluttering by nightjars as a means to regulate temperature is well known. This is however my first personal observation of this behaviour. Fowler and Miller, 2003, say \u2018Nightjars dissipate heat by gular fluttering, during which the mouth is opened, the rate of blood flow to the buccal area is increased, and the moist gular area is rapidly vibrated<\/em>.\u2019<\/p>\n
