Abstract:
During the Spring of 2011, we studied the bird community in an area of Val Borbera, in the province of Alessandria (NW Italy). In the study area, situated at an altitude between 655 and 1700 m a.s.l., we conducted 110 points count ten minutes each in four microhabitats (agricultural areas, shrubs, forests, and prairies). In total, we surveyed 72 species, of which 51 were passerine and 21 non passerine. The most abundant species were Sylvia atricapilla, Phylloscopus collybita, Apus apus, and Turdus merula. In the agricultural areas, we detected a total of 50 species (Sylvia atricapilla, Parus major, Turdus merula were the most abundant). In the shrubs, we detected 30 species (Sylvia atricapilla, Parus major, Fringilla coelebs, Phylloscopus collybita, Turdus merula, Erithacus rubecula were the most abundant). In the forest areas, we found 45 species (Sylvia atricapilla, Parus major, Fringilla coelebs, Phylloscopus collybita, Turdus merula, Erithacus rubecula were the most abundant), and in the prairies, we detected 48 species (Alauda arvensis, Anthus campestris, Sylvia atricapilla, Turdus merula, Anthus trivialis, Sylvia communis were the most abundant). Compared to the other macro habitats, the agricultural areas have a significantly high abundance and richness in species, which highlights the importance of the agricultural mosaics in the Piedmont and mountain areas. The data which has been collected so far confirms the important role of this area, given the presence of some species which are rare at a regional scale.

Abstract:
The expansion of the Chiffchaff Phylloscopus c. collybita in southern Sweden during the last decades is well documented. Regionally the densities of the Chiffchaff now even exceed the densities of the ubiquitous Willow Warbler Phylloscopus trochilus. However, there are few quantitative studies on Chiffchaff densities, not least from urban areas. During spring 2013 a survey of singing Chiffchaffs and Willow Warblers, complemented by territory mapping, was conducted in three villa suburb areas (total ea 1.27 km2) and a nearby recreational area in the southwestern parts of the city of Malmö, Sweden. The villa areas held a substantially higher number of Chiffchaffs (16.5 pairs/km2) than Willow Warblers (6.3 pairs/ km2). In one villa sub-area, with little undergrowth and denser housing, there were no Willow Warblers at all, in contrast to the recreational area close to the villa areas, where the Willow Warbler dominated (10.9 pairs/km2). The Chiffchaff had its highest density (18.7 pairs/km2) in the sub-area that had the largest trees. Thus, in the investigated villa suburb, the Chiffchaff clearly outnumbered the Willow Warbler as a breeding bird.

Abstract:
AbstractThe males of most bird species help to raise the young, and females may suffer costs from polygyny because of having to share the male parental care. In the chiffchaff (Phylloscopus collybita) nests of monogamously and polygynously mated females had similar success in relation to the proportion of fledged young. Overall, male chiffchaffs provided little assistance to females during the nestling period, but they increased help when the young left the nest. Females who choose already-paired males (secondary females) incurred lower reproductive success, because they were unable to start a second brood after raising their first brood. Primary and monogamous females which received male help in the form of food provisioning during the fledgling period were more likely to attempt a second brood. This is the first study that reports associated costs to secondary females due to the lack of paternal aid after the young have fledged the nest. However, secondary females still can obtain compensatory benefits, as predicted by the polygyny threshold model, since most of them settled in good quality habitats, close to the primary females.

Abstract:
Abstract Song repertoire of geographically isolated Chiffchaff population that formed in Crimean mountains in 1990s is analyzed. There are 42 song elements in the Crimean Chiffchaff repertoire. A quarter of their song elements appear to be specific for this population because it is absent in neighboring European Chiffchaff populations from regions to the north (Ph. c. abietinus subspecies) and west (Ph. c. collybita subspecies). Comparison of song elements of Crimean Chiffchaffs with those of Caucasian birds of Ph. c. caucasica subspecies shows that they belong to same vocal population: specific elements in Crimean Chiffchaff songs are found also in songs of Caucasian birds. This is evidence that breeding population of Chiffchaff in Crimea originated from the species expansion from Caucasus, and that Crimean Chiffchaffs belong to Ph. c. caucasica subspecies.

Abstract:
AbstractBreeding birds were counted using point counts at 50 treefall gaps and 50 closed-canopy sites within one of the largest tracts of old-growth forest in Europe. Numbers of species and individuals were slightly, but significantly, higher at gaps. Overall bird species composition differed substantially at gaps and non-gaps. Dunnock (Prunella modularis), Blackcap (Sylvia atricapilla), and Chiffchaff (Phylloscopus collybita) were significantly more abundant at gaps. Wood Warbler (Phylloscopus sibilatrix) and Red-breasted Flycatcher (Ficedula parva) were significantly more abundant at non-gaps. Warblers (Sylviidae), ground insectivores, ground nesters, and short-distance migrants were significantly more abundant at gaps, but no species groups were more abundant at non-gaps. Eight species breeding in forest edges and young plantations in eastern Poland were not recorded in natural treefall gaps. The proportion of tropical migrant passerines was considerably higher in closed-canopy stands (0.47) than at gaps (0.29), which contrasts with the situation in most managed European forests where the highest proportions of tropical migrants typically occur in young-growth forests.

Abstract:
Common chiffchaff Phylloscopus collybita is an insectivorous migrant passerine, which has been noted wintering in Britain and Ireland, in small numbers, from the early 1800's. Since the early 1970's the frequency of winter individuals has increased considerably, with around 1,000 estimated to have wintered in 1982/83. This thesis investigates the observed changes in wintering abundance and distribution in a novel wintering range during a period of rapid climate change. The majority of wintering individuals are found in the south and west of the British Isles, associated with the maritime climate and elevated temperatures compared to co1der inland and northern locations. At inland and northern sites locally warmer micro-climates are utilised, particularly waste water treatment works, which provide a regular source of invertebrate food above that available from the surrounding countryside. Winter abundance was investigated over 38 winters, and show that a 20 fold increasing in observer wintering numbers had occurred. Occupied winter range, between surveys in the 1980's and mid 2000's had also increased, with more inland sites were being occupied. The two main drivers behind this increase was reduction in winter severity and an increasing western European breeding population. Temporal trends in migration timing in Europe, over a 44 year period, showed that spring departure had commenced earlier and autumn migration was later, however, there was no change in distance travelled between western and central European populations. Genetic and morphological analysis showed that the British wintering population was comprised mostly of individuals originating from western Europe, with a small but increasing number for Asia and a minority from northeast Europe. Estimates of annual survival showed that birds at wintering sites had similar survivors hip to British breeding birds, which winter further south in Europe, indicating that southern England is a viable wintering location.

Abstract:
My study deals with general individual characteristics in songs of a passerine bird species Chiffchaff (Phylloscopus collybita), especially I examines the potential of these characteristics for application in acoustic monitoring of bird individuals. I have found that Chiffchaffs have individually distinct songs but unfortunately, song features I measured were not stable in time and hence they would not be suitable for long-term monitoring of individuals. My study suggests that acoustic individual recognition might be challenging in songbird species due to the complexity and plasticity of their song.

Abstract:
A playback experiment in which a recording of vocalization is played to the tested subject and its response is observed, is a widely used tool for examining bird song and its functions. Most often only acoustic stimulus is used, but sometimes a visual stimulus is also provided in the form of a dummy. Taxidermic mounts or models made from different materials are used as the dummy. It is discussed among researchers, whether it is or is not necessary to use a dummy in experiments and how does its presence affect behavior of the tested individuals. However, only few studies directly focus on this issue and test the effect of dummies. The best way to test the effects of a dummy on passerines in playback experiments is to test the same individuals in both situations (with a dummy and without a dummy) and compare the reactions. The aim of this theses was to perform such experiments on Chiffchaff (Phylloscopus collybita) and Yellowhammer (Emberiza citrinella) males and to find out whether they would behave similarly in both variants of the experiment, or if their reaction would be enhanced in the presence of a dummy. Chiffchaffs reacted significantly more aggressively in the dummy experiment. The biggest difference was time spent by attacking the dummy and staying close to it. In Yellowhammers, the dummy...
