Another day, another displaying Sparrowhawk - this time an exuberant male flying in elaborate, slow-flapping circles over tea-time Cardonald. As with yesterday's female, the white of the undertail coverts was very obvious, almost suggesting a white rump. According to Leslie Brown, display can take place at any time of year, but away from the breeding season may have more to do with defining territorial boundaries than impressing a mate. Whatever the purpose I have no doubt that these birds were tempted to display by the glorious, sunny afternoons on both days.
