The first breeding records of the Bearded Vulture Gypaetus barbatus for more than 120 years were the highlight of the year 2007. The Montagu´s Harrier Circus pygargus bred for the first time since 1986, the Northern Shoveler Anas clypeata for the first time since 1997 and the Mew Gull Larus canus for the first time since 2000. For the second year running, a Lesser Blackbacked Gull Larus fuscus bred with a Yellow-legged Gull Larus michahellis. The Woodchat Shrike Lanius senator bred again after missing the year before. After being present for six years during the breeding season, the Moustached Warbler Acrocephalus melanopogon was not seen in 2007. As a breeding bird, the Red-spotted Bluethroat Luscinia s. svecica declined as well as the Common Rosefinch Carpodacus erythrinus. The biggest ever influx of Griffon Vultures Gyps fulvus was noted, culminating in June. During the autumn, there was an invasion of Mediterranean Gulls Larus melanocephalus and during the winter 2007/08, an invasion of Caspian Gulls Larus cachinnans at Lake Constance and an invasion of «Northern» Bullfinches Pyrrhula pyrrhula for the fourth year running. Other uncommon winter records included the first overwintering of the Bar-tailed Godwit Limosa lapponica, the second overwintering of the Little Egret Egretta garzetta, the 8th overwintering of the Black Stork Ciconia nigra and another overwintering of the Common Crane Grus grus.
