Breeding birds in Sardinia (Italy). Status, distribution and population updated to 2016.
This is an update to the "Status, distribution and population of breeding birds in Sardinia (Italy) to 1995" published at the end of the last century by the same author. This work examines the species that have been breeding in Sardinia since the nineteenth century (or just before) up to 2016. For each species it highlights status, size of population and map of distribution in the most recent period (about the last 5-10 years). It also analyzes: a) the possible breeding species; b) the supposedly extinct species; c) the species considered for a long time as more or less regular breeding in the island, but which lack recent evidence and therefore can be regarded as "likely extinct"; d) the dynamics of the population and the variation of the distribution of each species in the most recent period (trend). In 2016, the breeding species in Sardinia are 167. The most represented Order is that of the Passeriformes with 67 species (40.1% of the total), followed by Charadriiformes with 17 species (10.1%), the Accipitriformes with 14 species (8.3%), by Anseriformes with 13 species (7.7%) and the Pelecaniformes with 10 species (5.9%). Less represented orders are those of the Phoenicopteriformes, of the Ciconiiformes, of the Otidiformes, of the Caprimulgiformes and the Bucerotiformes, each with one species (0.59%). On the contrary, the most represented families are those of Anatidae and Accipitridae with 13 species (7.7% of the total), followed by the Fringillidae with 9 species (5.3%), from the Sylviidae and the Muscicapidae with 8 species (4.7%), and the Ardeidae with 7 species (4.1%), the Rallidae and the Corvidae with 6 species (3.5%) and Laridae, the Sternidae, the Falconidae and Hirundinidae with 5 species (2.99%). Out of a total of 143 species that we have evidence of breeding in a recent period, 132 (79% of the total) can be considered regular breeding, 11 species (6.5%) are irregular breeding, and 14 species (8.3%) are occasional breeding species...........................(continued).

Black-winget Stilt, Sardinia (Giuseppe Sedda)

Changes in distribution and population numbers of water birds in the Molentargius – Saline Regional Park (South Sardinia).
Changes in distribution and population numbers of water birds in the Molentargius – Saline Regional Park (South Sardinia).
The
Parco Naturale Regionale Molentargius-Saline, in southern Sardinia, Italy, is
considered one of the most important areas for water birds in the island. The
reserve comprises of a wide variety of habitat, including saltpans, freshwater
ponds and Reed beds. Our study investigated the changes in spatial distribution
of twenty-two bird species over the post-breeding and wintering season in three
areas of this wetland in 2013. We have analysed the segregation of bird species
inside the reserve and their movements across the seasons; namely, waders and
Greater Flamingos are commonly found in relatively stable numbers in the
saltpans, while Anatidae, Rallidae and Ardeidae species,
including several rare ones (e.g. Night
Heron, Purple Heron), favour the canals on the wetland border.(* maralt2@yahoo.it)
Bearded Vulture, Corsica (Jean-Fançois Seguin)
Jean-François Seguin* & Marcello Grussu
Regarding the origin of Bearded Vultures recently recorded in Sardinia.
The Bearded Vulture disappeared in the 1970s from Sardinia (Italy) as breeding bird. Nevertheless, in the following years there have been repeated sightings of the species on the island, with 11 records regarding 12 birds in the period between 1980-2014. Sightings are distributed in the whole time period and all seasons except summer. The majority gravitates in the central and northern part of the island and four sightings are coastal. Age of birds, observation dates and changing status of the species in Europe show that the majority, if not the totality, of these birds belong to the near (7 Km) island of Corsica. In Corsica a small population of Bearded Vulture is still existing (5 pairs in the 2015) geographically isolated since the overall decline of this species during the 20th century in Europe. Sardinia being an island where scavenging birds of prey have difficulties to survive due to poisoning, these movements threaten Bearded Vultures from Corsica. This may reduce the survival of individuals and endanger the low numbers of birds in Corsica. (*jfseguin@pnr-corse.fr)

Notes on the distribution of the Goshawk in Sardinia.
In order to assess the distribution of the Corso-Sardinian Goshawk Accipiter gentilis arrigonii in Sardinia, we collected a series of data on breeding pairs status and localization: a) from our own observations relating to the period 2000-2011, b) from the literature and technical reports relating to the period 2000-2011, c) from existing data-sets (MITO2000, Ornitho.it) relating to the period 2000-2016 and d) from field surveys carried out in 2012 (and occasionally in the period 2013-2016). We found a minimum of 58 breeding pairs (38 confirmed, 10 probable, 10 possible); 38 pairs were detected at least once in the period 2010-2016, 11 pairs were observed in the period 2006-2009 and 9 pairs before 2006. Our data confirm the previously recorded distribution and substantially agree with the recent estimate of about 70 breeding pairs in Sardinia.(*londi.guglielmo@gmail.com)

Adult with ducklings of Marbled Teal, Sardinia (Massimiliano Podda)
Marcello
Grussu*& Massimiliano Podda
New
data on the breeding of Marbled Teal in Sardinia.
After
the first case of nesting in 2013, the Marbled Teal regularly bred in Sardinia
even in the period 2014-2016. Reproduction occurred on the same site with a
pair per year, but with a progressive increase in the population: two adults in
2014, five in 2015 and eight in 2016. Individuals remain in the breeding area
from May to September, the hatching of the eggs occurs in the period 14-23
June, the clutches consist of 4-15 chicks while 4-10/ pair were reared (an
average of 8 chicks/ pair). The breeding habitat is a permanent pond with fresh
water and rich vegetation of Phragmites australis, Juncus sp., Typha
latifolia, Typha angustifolia and Carex sp
. The site is located in a highly polluted area due to excessive load of
nutrients and heavy metals from the nearby mining areas and threatened by
uncontrolled human pressure. But the regular summer presence of the species in
2012 and the breeding in this area show that in Sardinia there are habitats and
ecological characteristics suitable for the stay of the species. In 2015, one
of the adults had been ringed in captivity in Spain and released on the island
of Mallorca (Balearic Islands) in February 2009. (*porphyrio@tiscali.it)
