IL PIRO PIRO BOSCHERECCIO TRINGA GLAREOLA IN ITALIA È UNO SVERNANTE REGOLARE
2019
The Wood Sandpiper,Tringa glareola, is a regular wintering species in Italy. We revised wintering status of Wood Sandpiper analysing 75 sightings (99 individuals) from December 2001 until January 2019. Data were collected from direct monitoring in Latium and Sicily and integrated by bibliography and national/regional data base. The species is regularly wintering with an estimate population of 1-9 individuals per year (mean value 1.32 individuals/sighting; DS=0.71). Tringa glareola was recorded in 40 sites, 20 Provinces and 10 Regions. Preferred wintering places are in Latium, Sicily and Sardinia. Utilised sites during last wintering seasons are increasing.
Migration patterns and fat reserves of Curlew Sandpipers Calidris ferruginea at a stopover site in southern Italy
2006
The Volturno Plain, southern Italian coast, is a regular stopover site for Curlew Sandpipers during northward migration. During 1992–1998, 2,177 Curlew Sandpipers were ringed and measured on northward migration; numbers trapped each year fluctuated. Peak passage was during the period 6–10 May, with 94% of birds trapped in the period 1–20 May. Median date of passage of males preceded females by about five days. Using a new visual method to evaluate fat deposition in waders, there was a strong correlation between body weight and visually estimated fat deposits. Birds showed a mass increase of 2.8 g/day. The mean stopover duration was 2.2 days. Only 0.9% of the total catch of Curlew Sandpipers…

Behavioural responses of breeding arctic sandpipers to ground-surface temperature and primary productivity
2021
Most birds incubate their eggs, which requires time and energy at the expense of other activities. Birds generally have two incubation strategies: biparental where both mates cooperate in incubating eggs, and uniparental where a single parent incubates. In harsh and unpredictable environments, incubation is challenging due to high energetic demands and variable resource availability. We studied the relationships between the incubation behaviour of sandpipers (genus Calidris) and two environmental variables: temperature and a proxy of primary productivity (i.e. NDVI). We investigated how these relationships vary between incubation strategies and across species among strategies. We also stud…
NOTE SUI LIMICOLI SVERNANTI NELLE ZONE UMIDE COSTIERE DELLA PROVINCIA DI TRAPANI
2016
Notes on wintering waders in the coastal humid zones of province of Trapani (Sicily). The coastal wetlands of Trapani still are of great national importance for migratory and wintering waders despite the dramatic reduction occurred in the last hundred years. During this research the author carried out surveys in coastal wetlands from Trapani to Mazara del Vallo, in order to estimate qualitative and accurate quantitative values of wintering waders. The census includes four winters, from 2012-13 to 2015-16 and was carried out in the months of December and January. Noteworthy is the wintering for three consecutive years of the Terek Sandpiper Xenus cinereus, the wintering of Oystercatcher Haem…
