Article summary

After a Spring that was unusually warm, dry and sunny, early June marked a return to more variable conditions. July 2011 was unseasonably cool. August also was rarely sunny, mostly cool and very wet. A few pre-breeding migrants were still seen in June, including two male Common Rosefinch Carpodacus erythrinus seen in Luxembourg. On 15 – 16 June three Griffon Vultures Gyps fulvus stopped over in South Luxembourg. The months of June and July are also the time where the results of nesting become evident. Among waterbirds, at Harchies, a Squacco Heron Ardeola ralloides was seen and there was some indices of Spoonbill Platalea leucorodia nesting. In marshy habitats, breeding of Savi’s Warbler Locustella luscinioides is probable and numbers of the Sedge Warbler Acrocephalus schoenobaenus continue to recover. Apart from the Hen Harrier Circus cyaneus, harrier breeding was not successful this year. Grey-headed Woodpeckers Picus canus seem extremely rare. Reproduction of the Black Grouse Tetrao tetrix was probably affected by the spring fires that happened across a large part of the Fagnes bog (reduced food supply, loss of nests). Two Short-toed Eagles Circaetus gallicus were seen in July, a young Red-necked Grebe Podiceps grisegena was seen in August. There were unusually early sightings of Merlin Falco columbarius in mid-August. There were also two ringing captures of Aquatic Warbler Acrocephalus paludicola and three captures of Barred Warbler Sylvia nisoria.
