Despite the obvious movement of migrants throughout the day, there were still no scarcities amongst them. The more noteworthy sightings of the day included the pair of Turtle Doves, a Cuckoo, a Tree Pipit, a smart male Black Redstart, a Lesser Whitethroat and a Garden Warbler. Eight Swifts, six Sand Martins, 102 Swallows and 22 House Martins represented a steady passage of birds throughout the day, whilst 24 Sedge Warblers, 26 Whitethroats, 19 Blackcaps, two Goldcrests and 11 Spotted Flycatchers were amongst a small number of Willow Warblers and Chiffchaffs.

 A few weeks ago, a single Gannet was seen prospecting for a nest site on the east side, as it dropped several times onto the grassy slopes. In the last few days, there has been a pair flying back and forth along the east side, although its probably a bit late for nesting now

The moth traps are finally yielding some more Lepidoptera recently, with last night’s totals including the first Small Magpie and Green Carpet of the year, and this stunning Treble-bar. This is the first record for the island, and was separated from the similar Lesser Treble-bar by the distinct shape of the tip of the abdomen when viewed from below. In males (such as this one), the tip has long, pointed claspers, narrowing down to quite a small point; in Lesser Treble-bar, the claspers are shorter and curved, with the tip being blunter.
