Even though the hobby had initially closed on the scream from the west, it climbed right past before suddenly turning and stooping from the east 'out of the morning sun', momentarily blinding its victim and causing a fatal delay before the swift commenced evasive action. Whether the hobby found the best angle of attack by accident, from experience or on instinct, such fine margins spell the difference between success and failure, life and death.birdman_eustonhttps://www.blogger.com/profile/09232990514600770658noreply@blogger.comtag:blogger.com,1999:blog-16314333.post-56810679625709001962012-08-27T12:16:14.952+00:002012-08-27T12:16:14.952+00:00This comment has been removed by the author.birdman_eustonhttps://www.blogger.com/profile/09232990514600770658noreply@blogger.comtag:blogger.com,1999:blog-16314333.post-17663529636188863832012-08-14T14:02:04.462+00:002012-08-14T14:02:04.462+00:0014 Aug:

I barely had time to wonder where the two new ones had come from when they were followed in by the Hobby, which gained height on approach before choosing its victim. The most impressive thing about this aerial feat was how little energy the Hobby expended: it simply used gravity to boost its speed advantage, caught up to one of the fastest birds in the world a few twists and turns later, and exited the Park stage right within two minutes of its arrival, trailing swift feathers in its wake. Truly awe-inspiring... I turned back to find the remaining swifts had rapidly gained height to form a scream of eight 150-200m up - no doubt a survival strategy of 'safety in numbers' at sufficient height to hedge against another 'death by stoop'.<br /><br />Gadwall 1 (drake in breeding plumage off area 2 at 06:20; first of the 'autumn').<br /><br />Swift 9 (then 8).<br /><br />House Martin 2.<br /><br />Chiffchaff 6+ (three among the roses in SW corner of Queen Mary's Gardens, area 19 at 07:10; singles calling in areas 10, 19 and 40).<br /><br />Willow Warbler 2 (with the Chiffchaffs in QM Gardens).birdman_eustonhttps://www.blogger.com/profile/09232990514600770658noreply@blogger.comtag:blogger.com,1999:blog-16314333.post-42744752325186682792012-08-14T13:51:09.717+00:002012-08-14T13:51:09.717+00:00This comment has been removed by the author.birdman_eustonhttps://www.blogger.com/profile/09232990514600770658noreply@blogger.comtag:blogger.com,1999:blog-16314333.post-59647475152071455292012-08-13T20:30:45.753+00:002012-08-13T20:30:45.753+00:00Buff Tip caterpillar seen crawling rapidly across ...Buff Tip caterpillar seen crawling rapidly across the path next to the Bird Sanctuary at 1pm.
