Abstract Ornithological pre-investment monitoring at planned wind farm sites is a standard and obligatory procedure in Poland and other EU countries. Pre-investment wind farm monitoring has a very important ‘side effect’ to its main goal (the safety of bird populations), namely the collection of valuable avifaunistic data from many localities that most probably would never be studied if not for the obligation to prepare environmental reports when wind energy investments are planned. The main aim of this paper is to show what we can learn from obligatory pre-investment monitoring when the standard field monitoring procedure and unified evaluation methodology are used. As an example the Common Crane Grus grus was selected, as a bird listed in Annex 1 of Directive 2009/147/EC and easy to identify and count. The data were collected at 155 controlled monitoring sites all over Poland, but mainly along the Baltic coast and in the Masurian Lake District. The methodology of the data collection and evaluation of results was strictly according to a paper by Busse (2013). The presentation of the results includes the numerical distribution of cranes in all seasons and some details of their behaviour - observations of birds on the ground and those using the air space: below the future rotor swept area of the wind turbines, at the rotor swept height, and flying above it. The estimated collision rates vary depending on the area, season and local heights of movements. It was concluded that such an evaluation of data already collected could be helpful in evaluating a particular site in comparison with other, previously studied localities.

Abstract The Palearctic-African bird migration system has fascinated ornithologists for decades and is one of the most well-known. However, there is strong spatial variation in the level of knowledge, and the South-Eastern European Flyway (which passes through the Balkan Peninsula) has been studied far less than the Western European Flyway (which passes through the Iberian Peninsula and Italy). In this study, we describe the phenology of 16 common woodland species, with a detailed analysis of the pre-migration period as well as an age-specific analysis of the timing of migration. As a general trend for species wintering in sub-Saharan Africa, adult birds migrated before first-year birds, in contrast with short-distance Mediterranean wintering species, in which we observed no difference. We also provide information comparing the timing of the migration of birds with characters of subspecies of Willow Warbler Phylloscopus trochilus and Chiffchaff Phyloscopus collybita, which have not previously been reported.

Abstract Of 46,160 birds ringed in South African heronries from 1951 through 1987, 481 were subsequently recovered (recovery rate: 1.04%). Most of these birds were ringed in the Western Cape (N = 173), KwaZulu-Natal (N = 142) and Gauteng (N = 106). The age of the recovered birds ranged from 0 to 23 years. Almost two thirds were 0-2 years old, and only 1.2% were 15 years or older. The average age of the recovered birds was 4.9 years (N = 465). The mortality rate was highest in their first and second year (31-36%). Nearly one third of the birds recovered (N = 134) were sick or injured, and 30.6% had been shot. Relatively low mortality, a long life span and relatively low predation pressure may contribute to the great success of the Cattle Egret in colonising various parts of the world. The paper presents the initial state for the likely future evolution of the distribution of the species.

Abstract Due to the presence along the Polish Baltic coast of migratory bird flyways from north-eastern European breeding grounds to wintering areas distributed on continental shelf waters of western and southwestern Europe, the area has been designated as a NATURA 2000 site (PLB 990002). Therefore the site of a planned off-shore wind farm in this area requires monitoring as to its potential influence on birds. This was the first such monitoring performed in Poland. The expanse of water covered by the research included the planned location of the wind farm as well as adjacent areas. A series of 15 investigative cruises were undertaken from the beginning of October to the beginning of May. The period of observations was divided into five seasons: early autumn, late autumn, winter, early spring and late spring. The standard method of counting birds on transects in the form of strips reaching 300 m from the ship was used in the research, as well as the ‘snapshot’ technique (scan with bands transect with snapshot technique). Additional observations were made from a point on the shore. In the study area maritime birds are present in low or moderate densities, with localized clusters. Two diving benthophagous species dominate: the Long-tailed Duck (58.9%) and the Velvet Scoter (34.3%). The next two commonest species have a share of over 1% within the community – the Common Scoter (3.2%) and the Herring Gull (2.4%). Other species are very uncommon. There is very high fluctuation in the number of birds both observed on the water surface and seen in the air. In the area studied no pronounced migratory passage of waterfowl was observed; the usual migratory flyways probably lie farther to the north and the birds observed in flight perform mainly local movements. Observed bird densities in the study area are considerably lower (52.0 ind./km2) than those estimated for the entire NATURA 2000 area (116.7 ind./km2). In the area of the planned wind farm densities are even lower (36.1 ind./km2, i.e. 31% of the NATURA 2000 level), while densities in neighbouring areas are still below the NATURA 2000 average. In the subsequent administrative procedure the area was not accepted as the location of the planned wind farm.

Abstract The Wicie ringing station was one of several stations which cooperate within the SEEN organization (SE European Bird Migration Network). The station was located west of the small village of Wicie located in northern Poland on the central part of the Baltic Sea coast. The station was situated on a narrow spit between Kopañ Lake and the Baltic Sea and has operated since 2010. Data were collected during three spring and five autumn seasons. Birds were caught in mist-nets, which were placed mainly in bushes and reed beds. Over 55 000 birds of 113 species were caught and ringed during eight migratory seasons. Many of them were also tested for directional preferences in Busse’s cages.

Abstract The algorithm for bird radar echo selection was developed in Israel and has been successfully used for many years to monitor birds in periods of massive intercontinental migration in order to ensure flight safety in civil and military aviation. However, it has been found that under certain meteorological conditions the bird echo selection algorithm does not filter out false signals formed by atomized clouds and atmospheric inhomogeneities. Although the algorithm is designed to identify and sift false signals, some useful echoes from smaller birds are erroneously sifted as well. This paper presents some additional features of radar echoes reflected from atmospheric formations that can be taken into account to prevent the loss of useful bird echoes. These additional features are based on the use of polarization, fluctuation and Doppler characteristics of a reflected signal. By taking these features into account we can reduce the number of false signals and increase the accuracy of the bird echo selection algorithm. The paper presents methods for using radar echoes to identify species and sizes of birds, together with recommendations on using the data to ensure flight safety during periods of massive intercontinental bird migration.

Abstract The scientific knowledge available in many detailed studies needs, from time to time, some generalization that allows to provide a synthesis or at least presentation of certain problem to both, scientific community and wide public interested in the topic. This article presents evolution of the presentation style of spatial course of the passerine migration in the Western Palaearcic. According to developing knowledge in the topic the style of presentation of general migration pattern evolved from a “line–arrow ” style suggesting that the birds use narrow “corridors” to more adequate to the phenomenon “carpet” style with called as “bottle-necks” concentrations being local and temporal effects of existing migratory barriers and guiding lines as maritime coasts, mountains and deserts. These details of migratory flyways are less visible in nocturnal passerine migrants than diurnal movements of both of passerines and gliding big birds. Generally, according to spatial relations between breeding and wintering areas of the bird populations living in Western Palaearctic four main flyways are defined and presented on maps: Western (Atlantic), Central (Apennine), South- Eastern (Balkan) and Eastern (Indian). Their background lies in the post-ice age history of distribution changes of the bird species, but details still evolve.

Abstract We studied the population trend and movements of the Song Thrush during the winter near the Tyrrhenian coast in the region of Latium, from 2012 to 2014, in order to establish the timing of spring migration. During standardized mist-netting we captured and ringed 431 birds. The data collected indicate that the study area is mainly visited by wintering thrushes with significant year-toyear fluctuations in the number of birds. Based on the information gathered during this study, confirmed by the results of other studies carried out in southern Italy and France, we assume that spring migration starts in Latium between the second and third decade of February.

Abstract Work begun in autumn 2013 at a research ringing site near Jericho in the Jordan Valley (Palestine) was continued in spring 2014 (8 March–18 April). Due to a flood, the area was much changed in relation to the autumn habitat distribution. Standard ornithological and ringing work was performed using mist nets. The methods used were in accordance with SEEN (SE European Bird Migration Network) standards, and apart from ringing included some measurements (wing length, tail length, wing formula) and scores (fat determination and body mass), as well as testing of the directional preferences of migrants. The ornithological work was expanded to include parasitological testing, taking into account migrant-helminth relations during migration. Altogether 508 birds from 44 species were ringed and inspected for external signs of infection by Collyriclum faba trematodes (subcutaneous cysts), and an additional 32 dead individuals were collected and dissected. Altogether 168 internal parasites were found. The most common migrants in spring were Lesser Whitethroat Sylvia curruca, Blackcap Sylvia atricapilla and Olivaceous Warbler Hippolais pallida, while the autumn dominants–Masked and Red-backed shrikes (Lanius nubicus and L. collurio) were scarce. In spring a good number of Dead Sea Sparrows Passer moabiticus were caught, but only two introduced Indian Silverbills Lonchura malabarica.

ABSTRACT The Yellow-browed Warbler is a species of the Sylviidae family that breeds in Asia and winters in South East Asia and western Europe. In northern and north-western Europe it is considered one of the most numerous nocturnal migratory species from Siberia. In the southern and eastern part of the continent there are fewer observations of the presence of the species in passage or in winter. On 29 September 2013, during a ringing session in the southern part of the Danube Delta (Romania), we captured a juvenile individual of the Yellow-browed Warbler. This is the first record of the species in Romania.
