Activity of the ringing station of Capo Spartivento (Sardinia) in the period 2001-2009.
Activity of the ringing station of Capo Spartivento (Sardinia) in the period 2001-2009.
The paper reports the
results of the first nine years of activity of the ringing station of Capo
Spartivento (38°53’ N – 08°51’E) (Domus de Maria, Cagliari, Italy). A total
number of 10,676 birds and 64 species were trapped during the study (including
2,442 retrapped birds), with a yearly average of 1,186.2 and 38.8,
respectively. The most common species were the Robin (overwintering) and the
Sardinian warbler (breeding and dispersal during summer), and secondarily the
European Greenfinch (resident), Sardinian warbler (resident) and Blackcap
(Palearctic migrant). In order to evaluate the differences the community
structure during the year, we subdivided the 12 months period into six
phenology classes (wintering, two pre-reproductive, breeding, two post-reproductive
periods). The dominant and sub-dominant species of each period were quantified

The reproduction of the Greater Flamingo Phoenicopterus roseus in Algeria in 2005 and 2006.
The western Mediterranean population of the Greater Flamingo is structured as a metapopulation with a relatively small number of breeding colonies. North Africa has traditionally been perceived as a wintering ground or a kind of "crèche" for immature birds. Starting from 2002, a systematic survey of the wetlands complex of the Algerian Hauts Plateaux revealed an important wintering and aestivating population of greater flamingos (30,000 + birds). More search led to the discovery of a breeding colony at Garaet Ezzemoul. Protective measures ensured the successful reproduction of the Greater Flamingo, the first so far recorded in Algeria, in 2005 (6,000 pairs) and 2006 (4,750 pairs). In August 2006, a total of 208 chicks were banded and their movements monitored across the Mediterranean Basin. Preliminary data have revealed extensive exchange between the Ezzemoul and European colonies and dispersal of some Algerian chicks to Europe. The future of the Ezzemoul colony, like its counterparts in the western Mediterranean, is however far from secure being especially threatened by human disturbance, hydrological changes and habitat loss.

On the breeding of Bearded Vulture in Sardinia.
We report the data concerning a nest of Bearded Vulture in the Codula di Luna valley/ Urzulei (Sardinia), occupied by the species in 1926 and rediscovered in 2005. The photos of the individuals (adult and juvenile) at nest, taken in 1926 by the Swiss naturalist Carl Stemmler, are the only photographical evidence of the species breeding in Sardinia, as well as the first one related to the Italian autochthonous population. It is an unusual nest, as it is placed in the lower third of a wall at 4.5 m from the ground level and at a height of 600 m above sea level; whereas in the Western Palearctic region the species usually breeds at a great altitude and anyway at least at 10 m from the ground and 700 m above sea level. Moreover, the nest from Urzulei is exposed to potential predatory mammals. The use of this particular nest, despite the near presence of alternative breeding sites, could be explained by especially favorable conditions of the breeding area, such as shelter from the prevailing winds and other inclemency of the weather or the relative peace of the site.

Notable winter records of Wood Sandpiper and Temminck’s Stint in Sardinia.
Wintering presence of Wood Sandpiper and Temminck’s Stint have been recorded during the winters 2004-05 and 2005-06 in Southern Sardinia, Italy, where single or small flocks of up to three (Wood Sandpiper) and five (Temminck’s Stint) individuals have been recorded in the in Santa Gilla Lagoon. This data represent an interesting record for the island, where single and single-two wintering individuals of the two species, respectively, were irregularly recorded in the past.

The Rook in Corsica (France).
The Rook was never recorded since 1960 in Corsica (Mediterranean France). But, a wild individual, was watched in December 2003. This record was obtained in the context of a partial extend of this species in Southern Europe, but is still the first to the beginning of 2009. We indicate also the other hypothesis that can explain such record.

On the origin of Common Crossbills Loxia curvirostra invading Sardinia.
In spring 2003, I discovered in two mountain ranges (Monte Limbara/ Monte Masiénnera, North Sardinia) larger groups of crossbills. It seems highly likely that some of them were also breeding in this year. An analyse of their vocalisations revealed that these crossbills came originally not from Corsica, but from the European mainland.

First record of White-rumped Swift in Sardinia.
An individual of White-rumped Swift was observed on June 21st 2008 in northwestern Sardinia near Bosa. It is the first record in Sardinia. Discussion follows about identification and distribution of this species in the Western Palearctic Region
