25th September

Another quiet start in the continuing warm sunshine kicked into gear mid-morning with a fly-over Red-throated Pipit proving to be the exciting prelude to a busy period of overhead passage that saw in excess of 2000 House Martins, together with lesser totals of Swallows and Sand Martins, descend across the Bill before continuing their journey southbound. Sadly, the Red-throated Pipit was - very typically for Portland records of this most tricky to catch up with species - a blink and you miss it event, with only a lucky few within earshot as it flew westwards over the Obs. Not that there was much time to dwell on what we missed as the almost simultaneous arrival of the House Martins saw all ringers called to action for a busy couple of hours that saw 341 new birds ringed - the highest day-total since the heady days of 1985-86 when a huge catching effort saw annual totals in excess of 1500 achieved. All of this activity helped disguise the fact that it was otherwise a quiet day for migration, with a meagre tally of Chiffchaffs and Blackcaps and a Common Snipe the only other grounded migrant of note. The sea fared somewhat better, with another 2,000 auks plus 19 Balearic Shearwaters, 6 Arctic Skua and a Great Crested Grebe also logged.

Following on from yesterday's blogpost regarding all of the recent Lesser Emperor activity, another exciting event over the last few weeks has been the discovery of multiple Large Conehead bush-crickets holding territory around the Bill. After the first island record of a single in a moth-trap back in the middle of August, there had been no further sightings by day; however, some nocturnal wanderings during the recent calm weather uncovered three singing males in the Crown Estate Field and a further individual at Culverwell. Whilst there has been no confirmation of breeding, it seems highly likely that we will see more records in the coming years as they spread outwards with a warming climate. This is the first individual from a moth-trap back on 15th August...


...with further individuals located by song at night including a more unusual brown morph individual:
