A census was carried out using the method of transects along stretches of coast of the Province of Trapani in order to estimate the wintering population of Common Sandpiper and Ruddy Turnstone. Although the International Waterbird Census (IWC) provides accurate estimation of wintering waders in Italy, the number of wintering individuals of Common Sandpiper Actitis hypoleucos and Ruddy Turnstone Arenaria interpres are strongly underestimated. The reason for this underestimation lies in the type of habitat they are used to populate along with the solitary life habits of the Common Sandpiper. To address this issue, we inspected 46.9 km of coastline where we recorded to 92 Ruddy Turnstones and 56 Common Sandpipers. For both species, the sites (coast) where bird-sightings occurred were marked with georeferenced data and classified as harbour area, sandy, rocky (including vermetid reefs) and posidonia banquettes. For each species, the IKA (Index of Abundance per Kilometer) was calculated, both global index and relative to each type of coast. As for the Common Sandpiper we observed 87 individuals, between transects and spot observations in the province of Trapani, which is the 22% of the whole wintering population estimated in Italy. Notably, even greater is the importance of our observations of the Ruddy Turnstone, which accounting for up to 154 individuals corresponds to the 71% of the whole Italian wintering population. Projection of these data to the entire Italian coast allows estimating a wintering population in Italy much larger than that reported so far, especially for the Common Sandpiper, which uses not only the sea cost but also inland wetlands and rivers as suitable wintering habitats for wintering.

Levels of nesting site selection were identified: landscape level is related to birds’ choice of landscape with yellow, pink, white, and green aspects. Ecosystem level corresponds to the detection of a water body by birds. The birds detect a station with the necessary vegetation association, where grasses and meadow halophytic associations are the basis of vegetation. The local (point) level is caused by the presence of a necessary host plant, which is a protector of birds’ nests. The main signals for the selection of nesting conditions for yellow wagtails as a reflection of semiotics are (in order): landscape – habitats of predominantly yellow, less frequently pink, white and green aspects; ecosystem – proximity of a water body (river, lake, etc.); statistical – halophytic associations. The following aspects of the nesting habitats are considered: ecosystem – proximity to a water body (river, lake, etc.); statistical – halophytic vegetation and grasses on sandy loam, loamy, solonchak soils suitable for nesting holes; local (point) – presence of host plant to protect the nest. Birds select nesting habitats based on the availability of all available signals, which increases the possibility and success of colony formation. The manifestation of semiotics: yellow wagtails in the nesting habitat tend to lose their visibility and dissolve into the background of the biotope, which is a special adaptation against predator attack.

Vigur Island, situated in Iceland’s Westfjords, is renowned for its diverse avian species, such as Atlantic Puffins and Black Guillemots, and its marine inhabitants including Harbour and Grey Seals. Despite its openness to tourism, the island is a subject of ongoing conservation efforts. This opinion paper argues for a more holistic approach to research on the island, highlighting the complex interplay between human activity and the island’s ecosystem. It critiques the current, often narrow, research methodologies that fail to fully account for the intricate relationships between species and their environment. The paper calls for a re-evaluation of habitat classification to incorporate the significant impact of avian populations and stresses the importance of adhering to Icelandic laws that mandate minimal disturbance to wildlife. With seasonal closures and careful management practices like eiderdown collection, Vigur Island serves as a model for balancing human interests with ecological integrity. This opinion advocates for adaptable, comprehensive research strategies that, while illustrated through the case of Vigur, should be applied universally, urging scientists to embrace broader perspectives in environmental studies globally.

Data were collected on the breeding biology of Common Sandpipers (Actitis hypoleucos) nesting in the middle course of Brenta River (NE Italy) in 1997. Birds occupied the territories from the end of March and laying mainly occurred in the second and third decade of April. Nests were found on sandy gravel beds, in the immediate vicinity of running water. Hatching success was low (58%), mostly due to predation by mammals. Human disturbance by sun-bathers dramatically restricts the areas suitable for breeding and therefore requires protection measures.

The conservation of Griffon Vulture (Gyps fulvus), the most abundant and widespread vulture in Europe, has been the focus of two LIFE project in Sardinia, that foresaw, among other actions, the release of individuals to increase population size. Within the project LIFE Under Griffon Wings (2015-2020), out of 76 Griffon Vultures that have been released in North Western Sardinia, 43 have been fitted with GPS/GSM tags. On the 3rd of April 2023, one of these Griffon Vultures, named “Caniga”, crossed the Strait of Bonifacio and reached Corsica. It stayed on the island for 20 days, before returning to Sardinia on the 23rd of April. Despite Griffon Vultures have been occasionally reported in Corsica in the last decades, this was the first time that one of the individuals released within the LIFE “Under Griffon Wings” project was recorded there. This observation provides evidence that expanding Griffon Vultures in Sardinia could also include Corsica in their movements and calls for the transboundary management of vulture populations between the two islands, including both monitoring and conservation actions minimizing anthropogenic mortality.
狮鹫（Gyps fulvus）是欧洲数量最多、分布最广的秃鹫，保护狮鹫一直是撒丁岛两个 LIFE 项目的重点。在 "狮鹫之翼下的 LIFE "项目（2015-2020 年）中，撒丁岛西北部放飞的 76 只狮鹫中，有 43 只安装了 GPS/GSM 标签。2023 年 4 月 3 日，其中一只名为 "Caniga "的狮鹫穿越博尼法乔海峡，抵达科西嘉岛。它在岛上停留了 20 天，然后于 4 月 23 日返回撒丁岛。尽管在过去的几十年里，科西嘉岛偶尔会有狮鹫秃鹫的报道，但这是第一次记录到狮鹫秃鹫在 LIFE "在狮鹫的翅膀下 "项目中被释放的个体之一。这一观察结果证明，撒丁岛上狮鹫的活动范围在不断扩大，也可能包括科西嘉岛，因此需要对两岛之间的秃鹫种群进行跨境管理，包括监测和保护行动，尽量减少人为死亡。
