Status, distribution and conservation of Kentish plover <em>Charadrius alexandrinus</em> (Aves, Charadriiformes) in Sicily
2021
The Kentish Plover Charadrius alexandrinus is a sensitive species whose national breeding population has been undergoing a sharp decrease, up to 50%, in 2010 compared to the previous decade. Due to the lack of updated data and fragmented knowledge about its current status and distribution in Sicily, a specific and accurate monitoring of this species was carried out during the years 2018 and 2019. About 230 km of coastline and 64 UTM squares 10x10 km were investigated during the breeding seasons, and a total of 205-287 pairs have been estimated for the whole region, distributed in 41 UTM squares (including the island of Favignana). Pairs are mainly concentrated in the complex of “Saline di T…
Indagine comparativa sulla popolazione nidificante di Fratino Charadrius alexandrinus (Aves, Charadriiformes) nelle saline della Provincia di Trapani
2016
Comparative survey on the population of the Kentish plover Charadrius alexandrinus in the salt pans of Trapani province. This paper deals with a 2016 census of the breeding population of the Kentish plover in the saltpans of trapani and of the Stagnone di marsala. In the same area a previous census of this species was carried out forty years ago by Massa (1977). the comparison between data collected in the 1970s and in 2016 reveals that the population of the Kentish plover has been dramatically declining, with 70% decrease in the overall area (ca. 1,230 ha). Although responsibile for an additional 8% reduction of wetlands in the last few decades, direct human intervention is not likely to b…
Nest Site Selection by Kentish Plover Suggests a Trade-Off between Nest-Crypsis and Predator Detection Strategies
2014
Predation is one of the main causes of adult mortality and breeding failure for ground-nesting birds. Micro-habitat structure around nests plays a critical role in minimizing predation risk. Plovers nest in sites with little vegetation cover to maximize the incubating adult visibility, but many studies suggest a trade-off between nest-crypsis and predator detection strategies. However, this trade-off has not been explored in detail because methods used so far do not allow estimating the visibility with regards to critical factors such as slope or plant permeability to vision. Here, we tested the hypothesis that Kentish plovers select exposed sites according to a predator detection strategy,…
