The return of winter catches

The return of winter catches

As usual (some say…), autumn is giving way to winter, and the MIGRATLANE team is changing targets. Although the solstice is still a long way off, the last migrants are passing through and wintering birds are gradually making their way to our shores.
After the autumn dotterels, the team has targeted migrating/wintering short-eared owls. A difficult harvest this year, with relatively few birds reported on the Atlantic coast. Three owls were nevertheless equipped in Brittany by Yannig and 2 in Charente-Maritime by Fanny. Sophie on the Island of Ouessant was less fortunate, despite the help of many volunteers who were on hand to help with the field work – thank you to them!
The cold weather also brought us fieldfares, another of the programme’s target species. Yannig and Julie have already caught 8 individuals in Finistère. The data collected, unprecedented in Western Europe, will provide a better understanding of the migration of these northern species and their ability to cross maritime areas. Thrushes are among the migratory species most regularly heard at sea in autumn.

In a different atmosphere these days, a large part of the team is on the Quiberon peninsula for a few days to start catching wintering seabirds at sea. So far, they have proved particularly difficult to find in the dark, drizzly conditions of Brittany. The weather has been a bit vexatious, causing a swell that has been hard on the stomachs and making it difficult to spot the birds in the thermal binoculars! To be continued…
