|The traps at Fringilla|
Last year’s A.R.G. report included an article by Richard Mooney on his visit to Rybachy with Bob Gifford and Andy Welch for a week in October. In 2000 Richard returned to Russia, this time for 2 weeks in September with Alan. Whilst on the first visit they spent more of their time at the Rybachy ringing station, this time the entire period was spent amongst the dune area of Fringilla situated in the centre of the Courish Spit. This site uses the characteristic ‘Rybachy’ (Heligoland) traps rather than mist-nets and offers considerable more freedom to visiting ringers.
The weather was changeable during the period covered. At the start of the visit the weather was generally mild and westerly, moving more southerly and getting windier and wet on the 13th and 14th. On the 15th the weather improved and the wind moved easterly, resulting in mass movements of finches (mostly Chaffinches and Siskins, and Bramblings from 16/9).
Although birds could be seen or heard constantly passing over the woods, it was only by watching from the dunes that the extent of the passage could be appreciated. Sample counts suggested that at there peak as many as half a million finches were passing overhead in a single day. Flocks of Jays and large numbers of tits were also moving over, but the most spectacular migration for us was the raptors, especially on the 15th and 16th. Few birds were seen on the inland lake, but from the 16/9 the numbers and variety of birds on the sea or flying south also improved.
3 Rybachy (heligoland) traps were in use each day, although traps 5 and 8 which faced SW caught nearly all the birds (trap 4 faced NE). Daylight was about 7:00 a.m. and it was dark at about 8:00 p.m., after which we amused ourselves either trying to catch owls or drinking vodka. The first drive of the traps at 7:00 a.m. was usually rather disappointing unless there were numbers of Robins moving, such as on 12/9 and 15/9, with most birds starting to move as the sun became brighter. The strong easterly winds were better for observing birds than trapping them, as birds generally fly higher and faster with a tail wind.
On most nights a line of high nets were set with tape lures playing Reed Warbler and Pied Flycatcher song. These produced some warblers, Robins and bats even in high wind. On several mornings some of the nets were left open for a few hours, and these produced both Bluethroats and the 1st Black Redstart.
On two afternoons 3 nets were opened around a small pond in the wood, but these generally only produced retrap tits (including Crested and Marsh), although some excellent birds such as Red-breasted Flycatcher were seen in the area but avoided capture.
There were 4 Russian scientists based at Fringilla for most of the period (Misha Markovets, Leonid Sokolov, Anatoli Shapoval and Marc Shumakov), but 2 German students were also present for some of the time (Julia Delingat and Pia Reufsteck). At Rybachy we met the Director (Casimir Bolshakov) and his main assistants (Nikita Chernetsov and Nadejda Zelenova). The nocturnal netting at Fringilla was carried out by Andrei Mukhin and Vladimir Fedorov.
A total of 108 species were recorded, of which 45 were ringed or retrapped. The total number of birds ringed whilst we were present was 1,556, the most common species being Goldcrest, Robin, Willow Warbler, Chaffinch and Great Tit. The weather was certainly not ideal for ringing during our visit, but it did give us a chance to witness the most remarkable visible migration you could ever see. The residents welcome visiting ringers and the potential that the site has for mass ringing is second to nowhere. As an example in our last few days we caught a few Long-tailed Tits, but by the end of October they had ringed a total of 19,800, a site record.
Every trip has its special memories. For me it was watching vast numbers of finches and raptors migrating along the coast, collecting amber from the tideline and of course, handling some unusual species such as Hen Harrier, Merlin, Cuckoo, Woodcock and Black Redstart. I have no doubt we will return, maybe in spring next time?
