Densities were estimated for several passerine longdistance migrant species associated with peri-urban wetlands and meadows in the city of Wroclaw (293 km2), SW Poland. Acrocephalus arundinaceus, A. scirpaceus, Locustella naevia and Lanius collurio nested in a crude density of more than 0.2 pairs/territorial males per 100 ha. The group of four other species (Saxicola torquatus, Locustella fluviatilis, L. luscinioides and Acrocephalus schoenobaenus) bred in a crude density between 1.1 and 1.5 pairs per 10 km2. The least numerous were the Sylvia nisoria (0.06 pairs per 100 ha) and Remiz pendulinus (0.02 pairs per 100 ha). Most of these species nested in the city in higher crude density than in a neighbouring rural area, richer of suitable habitats. Most breeding pairs occupied extensive peri-urban wetlands and meadows. These habitats could play an important role in conservation of these trans-Saharan migrants, as well as other water and marshland bird species. Such habitats are postulated to be protected as nature reserves or Special Protection Areas of the Natura 2000.
对波兰西南部弗罗茨瓦夫市(293 km2)近郊湿地和草地上几种远距离迁徙雀形目鸟类的密度进行了估算。粗密度为每100公顷0.2对以上的圆头棘足虫(Acrocephalus arundinaceus)、scirpaceus、naelocustella and Lanius collurio。其他四种(长尾沙螨、流尾沙螨、luscinioides和schoenobaenacrocephalus)的种群粗密度在每10平方公里1.1至1.5对之间。数量最少的是Sylvia nisoria(每100公顷0.06对)和Remiz pendulinus(每100公顷0.02对)。这些物种大多在城市筑巢，其原始密度高于邻近的农村地区，适宜的栖息地更丰富。大多数繁殖对占据了广泛的城市周边湿地和草甸。这些栖息地可以在保护这些跨撒哈拉迁徙鸟类以及其他水生和沼泽地鸟类方面发挥重要作用。这些生境应作为自然保护区或《自然2000》的特别保护区受到保护。

The Venice lagoon hosts the 15% of the entire Italian breeding population of Common terns, Sterna hirundo, highlighting the great value of the area for this species. However, in the last 25 years, a substantial decline of Common terns has been detected in the Lagoon, which culminated in 2008. The main causes of this negative trend were the loss of salt marsh habitats, where terns typically breed in the Venice lagoon. This was due to the increase in the mean sea level and the greater frequency of high tides during the reproductive period with consequent flooding of their breeding sites; competition with yellowlegged gulls (Larus michahellis), predation and human disturbance. As a preliminary experimental approach to counter the depletion of the species and favour its recovery, we performed a habitat loss compensation project by setting up four floating rafts (3x2m), covered by two different types of substrate (sandy and vegetal substrate). This was to function as an artificial nesting site safe from flooding, positioned in a protected internal wetland area of the Venice lagoon, Valle Averto (Sourthern Lagoon). We studied the colonization patterns of the rafts and the reproductive success of Common tern breeding pairs during the 2014 and 2015 breeding seasons. We also investigated those environmental and structural variables that could favour the use of the rafts and the nesting success of the species. In both years, the rafts were successfully colonized and used by terns for nesting. Our results also indicated higher temperature, lower rainfall and greater distance from the shore as the main habitat factors favouring the occurrence and the reproductive success of the breeding pairs, while a windrow of dead plants was indicated as the preferred substrate for covering rafts in order to make them more attractive. The results provided some suggestions for successful restoration plans to be developed in similar lagoon areas.

The regularization of the wintering status of the Jack Snipe (Lymnocryptes minimus) in NW Italy has been confirmed for the first time within the heathland of the “Baraggia di Candelo Natural Reserve” (Piedmont, Biella). Regular monitoring from winter 2009/2010 to winter 2015/2016 allowed to describe the phenology and the abundance of the species in the area comparing it with that of an ally species, the Common Snipe (Gallinago gallinago). A maximum count of 6 birds during winter and at least 13 individuals during the spring migration were recorded. The species was more abundant during the second 10-day period of November and the first 10-day period of March. Jack Snipe outnumber the Common Snipe throughout the period they were censused.
在意大利西北部的“Baraggia di Candelo自然保护区”(比埃拉皮埃蒙特)的荒原上，首次确认了杰克鹬(最小淋巴结)越冬状态的规范化。从2009/2010冬季到2015/2016冬季的定期监测，可以描述该地区物种的物候和丰度，并将其与盟友物种，普通鹬(Gallinago Gallinago)进行比较。冬季最多6只，春季最少13只。在11月的第2天和3月的第1天，种数最多。在调查期间，杰克鹬的数量超过了普通鹬。

L’ibrido presentava dimensioni e alcune caratteristiche del piumaggio tipiche di G. chloropus (mantello e parti superiori delle ali bruno-oliva; linea bianca dal profilo spezzato sui fianchi; sottocoda bianco con linea centrale scura), mentre il becco e lo scudo frontale apparivano di colore bianco candido, con sfumature rosate in corrispondenza delle narici, come tipicamente viene osservato in F. atra.

Analysis of the selection index, the niche breadth and the niche overlap of 10 species of wintering ducks in 11 wetland areas of the Campania region between January 2003 and 2015 revealed that the distribution of the species in the examined sites was not casual. In fact, each species actively chose their wintering area. Using selection index, we were able to measure the species’ preferences and non-preferences for the 11 examined sites. By calculating Shannon-Wiener entropy and its normalized value (Evenness), we determined niche breadth; the Morisita index allowed us to check niche overlap.

L’avifauna acquatica svernante include 29 specie; le più abbondati sono risultate germano reale e alzavola, con presenze anche di specie di interesse conservazionistico come moretta tabaccata e tarabuso.
