7 Introduction Bird migration is one of the most exciting phenomena of our living world, and therefore it is not surprising that it has been the subject of investigation since ancient times. Each year an estimated 5, million birds travel somewhere in the world. Short-distance migrants may just leave their mountainous breeding areas to seek milder winter conditions in the nearby foothills whereas long-distance migrants often cover tens of thousands of kilometres (ALERSTAM 199). The principal migratory routes for many species of passerines migrating from the Europe to African wintering sites are fairly well known. What is missing is a detailed analysis of environmental factors controlling bird migration as well as the temporal and spatial course of the migratory journeys (BAIRLEIN 1997, TIELEMAN 27). Palearctic-African migratory bird populations have to defeat several ecological barriers, like seas and deserts during the migration in postbreeding season and spring. During the migration driven natural selection population-specific strategies (e.g. habitat selection, food preference, fat deposition, migratory direction, migratory speed and dynamic, intra- and inter-specific competition, moult timing, etc.) and control mechanisms (e.g. photoperiodicity of hormonal system, nervous system and orientation, etc.) have evolved. The migration dynamics involves the evolution of the number, time and duration of the stopover of the migratory population on a territory for feeding or resting (BERTHOLD 1993, RAPPOLE & JONES 22). Many species of European bird species are currently undergoing rapid declines, but some birds have increasing and expansive populations (BIRDLIFE 24). The causes of these changes are not clear but factors like habitat fragmentation, agricultural technology, hunting and global climate change known to be seriously affecting certain European bird populations. Monitoring is essential for the identification of ecological and conservation problems affecting birds. According to the EC Birds Directive on the protection of European bird population, all European Community countries have an obligation to monitor bird population. In Annex V of the directive, specific reference is made to use bird ringing for the monitoring of population levels of migratory bird species. Birds are particularly good subjects for population monitoring because they are sensitive indicators of habitat changes. Annual counts of birds tell us how numbers are changing, but bird ringing is needed if we want to understand the mechanism of the observed changes. 7

8 Bird ringing for scientific purposes started in Hungary in 198, when JAKAB VÖNÖCZKY-SCHENK released White Storks that were ringed with metal rings engraved with numbers. Bird ringing and bird migration studies in particular were revolutionized in the mid-2. century when mistnets first became generally available. Mist-nets placed besides suitable vegetation readily capture passerines like warblers in their mesh. The BirdLife Hungary started a project called Actio Hungarica (AH) for investigation of bird migration in 1974 (SZENTENDREY et al. 1979). Actio Hungarica has been involved in the netting of migrating songbirds at a network of bird ringing camps in Hungary. The netting effort was strictly standardized and the habitat was not allowed to change, so changes in the numbers of birds captured should reflect changes in the migrating populations. The Tömörd Bird Observatory was founded in 1998 and it joined to the Actio Hungarica and the South-East Bird Migration Network (SEEN) that focuses SE flyway that has been poorly studied yet (BUSSE 2). Different types of useful information can be recorded when birds are caught for the purpose of ringing. These include the age and sex of the bird, a variety of measurements which can be used to characterize different populations, the amount of fat stored by migratory birds, the state of feather moult as well as the habitat in which the species was captured. Single birds can be recaptured by other ringers, resighted or recovered by members of the public in a variety of different ways: hit by cars, found dead, caught by cat, shot, etc. If a bird is subsequently recaptured by other ringers, resighted repeated measurements make the study of different aspects of the annual life cycle, such as body mass changes prior to migration or the seasonal progression of moult possible. The National Ringing Centres collect all the information provided by ringers and members of the public who find ringed birds. The Hungarian Ringing Centre of BirdLife Hungary is located in Budapest. When birds overfly national boundaries information needs to be exchanged between Ringing Centres and the European Union for Bird Ringing (EURING) ensures that this happens efficiently (KESTENHOLZ 27). Bird ringing has been carried out in Hungary throughout whole twentieth century. As the result, the long-term recovery and biometrical data for birds became one of the most valuable sets of information available for any group of animals. Despite all these ringing activities, many problems still remain unsolved, moreover, many more new ones recently emerged. For instance, the current global climate change the past decade has been the warmest for 1 years is confronting us with so 8

9 many rapid changes in the phenomenology of bird migration that we can hardly keep up with recording and analyzing them (BERTHOLD et al. 23). In this publication the autumn migration of birds captured in the Bird Ringing Project of Tömörd Bird Observatory between 1998 and 27 is characterized. A total of individuals of the 118 studied species were marked. The main aspects of the analysis were: 1. To register annual change of the migrating population size and trends found in migratory birds. 2. To describe the progress in time (dynamics) of the post-breeding movement by analysis of daily capture-recapture data. 3. To describe the habitat use of the migratory population by analysis of sites of captures. 4. To reveal the origin, migration direction and wintering sites of the migratory populations of Tömörd area by evaluating recoveries. Study site and field work Study area and methods The birds were captured and ringed at the Tömörd Bird Observatory (47 21'23"N 16 4'4"E) (Photo 1) in the west of Hungary. Tömörd is a small village in Vas County. It is located 15 kilometres from Szombathely (Fig. 1). Bird ringing took place during the autumn migration, from the end of July or early ust to the end of ober or early ember (Table 1). Fig. 1.

10 Table 1. Ringing activity periods Year Date and Jul Jul Jul Jul. 11. For catching the birds 29 numbered mist-nets (12 meter long and 2.5 meter high with 5 shelves and a mesh size of 16 mm) were used. The nets were positioned in four different habitat types around the ringing station (Photo 2). These were characterised below according to the SE European Bird Migration Network (BUSSE 2) (See below). Forest (W.LB6N.2EUPR.N.). The 6-9 m high trees and bushes made up a compact, dense edge vegetation. It had an ecoton community. Its characteristic plant species were: Quercus cerris, Prunus spinosa, Crataegus monogyna, Pyrus pyraster. There were 4 nets in this habitat (Photo 3). Bushy (S.BH2N.2PRCR.O.). The 2-3 m high bushes made up a compact, dense vegetation, which was dissected by small grass patches. Its characteristic plant species were: Prunus spinosa, Crataegus monogyna, Pyrus pyraster, Rosa canina. 11 nets were standing in this biotope (Photo 4). Grassland with scrubs (S.BG2N9.1ROCA.O.). It made a transition between the wet biotopes of the swamp and the steppe communities that used to cover the croplands around. There were a few bushes in the grassland. Its characteristic plant species were: Calamagrostris epigeios, Cirsium arvense, Arrhenatherum elatius, Verbascum thapsus. There were two small patches of Sambucus ebuli. There were 8 nets in this biotope (Photo 5). Marsh (S.TC1S..R.). Characteristic plants were Glyceria maxima, Typha latifolia, Salix cinerea. It was dried out in 2 and 21. 1

11 There was.5-1 ha open water in the other years. There was a line of 6 nets here (Photo 6). Data processing and statistical analysis All birds were ringed and aged according to SVENSSON (1994) and Actio Hungarica (SZENTENDREY et al. 1979). Biometric data were taken using the methods of Actio Hungarica. All birds were ringed, sexed and weighed to the nearest.1 g (using a spring balance). The wing and tail lengths were measured to the nearest 1 mm. The fat reserves were estimated visually according to BUSSE (2) ranging from (no fat) to 8 (bulging fat). Linear regression analysis and Pearson s correlations were used to determine trends in the number of yearly captures. The average daily captures of the years were compared using Kruskal-Wallis test. Migration curves and cumulative graphs for the age groups or sexes were calculated based on the average daily captures of the years smoothed by a 3-day moving average. Based on this information the peak migration period (when we captured the most birds in that season) and the month with the highest captures were identified. By using the minimum stopover time of the recaptured birds the migration dynamics curves were plotted. The beginning of migration was determined based the analysis of the fat score of the captured birds and the dynamics of daily captures. Birds on migration accumulate much larger fat reserves than in other seasons. This fact made it possible to distinguish residents from migrants, as well as the discrimination of the beginning of migration from the post breeding dispersal. In this study it was assumed that the beginning of migration was the day when the first passage of very fat birds i.e. in which the fat covered completely the intestines (fat score 3 or higher) was noted. The average date of the beginning of migration is marked with arrow ( ) on the migration curves. Linear regression analysis and Pearson s correlations were used to determine the trend observed in the change of the beginning of migration. The median dates of the migration were calculated with the exclusion of, the number of birds caught before the day starting the migration. The end date of migration was considered as the day after which only single individuals were captured in few-day intervals. The date of the end of migration is marked with arrow ( ) on the migration curves. The distribution of the captures in the different biotope types was checked by χ 2 -test for the year with the most captures. 11

133 Summary and discussion From the 118 species ringed in Tömörd between 1998 and 27 there were 14 dominant species (Fig. 199). These species, listed in order of decreasing occurrence were: Robin, Blackcap, Blue Tit, Chiffchaff, Tree Sparrow, Great Tit, Goldcrest, Blackbird, Yellowhammer, Greenfinch, Chaffinch, Swallow, Lesser Whitethroat, Whitethroat. Only the last three species migrated over the Sahara (CRAMP 1998). 71 per cent of all of the individuals ringed during the work were dominant passerine birds. No. of species dominant subdominant accessory rare Fig Number of species ringed according to dominance categories The number of birds ringed in the post-breeding dispersal and migration seasons in the study area around Tömörd showed considerable yearly fluctuations between 1998 and 27. The yearly numbers showed an increasing trend for Wryneck, Dunnock, Robin, Song Thrush, Garden Warbler, Blackcap, Chiffchaff, Short-toed Treecreeper, Red-backed Shrike and Great Tit between 1998 and 27. The yearly number for Grasshopper Warbler showed a negative trend between 23 and 27. There was a Blue Tit and Bullfinch invasion in 24. The number of Chaffinchs, Bramblings, Hawfinchs and Greenfinchs ringed in 25 was the highest because of the high amount of helianthus crop on the fields around the study area in that year. The number of Sparrows ringed in 23 was the highest because of the plenty of grain of wheat around Tömörd in that period. The marsh dried out in 2 and 21. For this reason the smallest number of Sedge Warblers, Marsh Warblers and Reed Warblers were ringed in those years. 133

134 The migration curves based on the average number of individual species ringed daily between 1998 and 27 showed that the temporal pattern of the migration of long-distance migratory species was different from that of the median- and short-distance migratory species. Birds could be classified into three distinct groups based on the migration dynamics characteristics of migration passage through the study area. The first group began the autumn migration as early as ust and terminated it in early ober. On average, the migration of five species, Swallow, Marsh Warbler, Whitethroat, Lesser Whitethroat and Thrush Nightingale started earliest in the first half of ust. Most of trans-sahara migratory birds left the study area by ober. The migration of the second group commenced in the last part of ust and tember and might last until the end of ober and early ember (e.g. Wren, Dunnock, Robin, Redstart, Chiffchaff and Great Tit). The third group included the short-distance and vagrant species with migration commencement in ober and migration termination by the end of ober and early ember (e.g. Blackbird, Song Thrush, Goldcrest and Reed Bunting). Based on the monthly data, ober was the migration peak period for the three dominant and shortdistance migratory species, Robin, Chiffchaff and Blue Tit in Tömörd. In the case of the long-distance migrants, the earlier and more intensive migration meant not only an adaptive migration strategy but resulted in the avoidance of the competition with the short-distance migrating species (BERTHOLD et al. 23).. Sedge and Reed Warblers and other long-distance migrants migrated over Hungary in ust and tember taking advantage of the anticyclones which occur most intensively to the West of Carpathian basin or over the Carpathian basin. The most migration peak days of these species observed during the anticyclones. These weather situations ensured good conditions to them, because there were only a few clouds and a light northern wind, which facilitated the orientation and movement of the birds. The cold front of the cyclones which appeared in the Baltic region or over Ukraine also took a great effect on the autumn migration of some shortdistance migrants, e.g. Robin, Blackcap, Chiffchaff, Goldcrest and Blue Tit (GYURÁCZ et al. 23b). One day after the cold fronts great numbers of individuals were caught in Tömörd. During the cold front the strong wind was favorable only when its direction was suitable for the migration (back wind), because in that case flying did not needed much energy. Moreover, birds could reach higher migration speed and they could minimize the time of migration. The long-distance and short-distance partial migrants preferred anticyclones during their autumn migration, but there were some 134

135 smaller differences in their migration patterns caused by the different behavior of the birds, because they followed different migration strategies to minimize the time and energy of the migration (BERTHOLD 1993). Among the four habitats, marsh habitat held species (e.g. Swallow, Sedge Warbler, Marsh Warbler and Reed Warbler) which were differed from those of the other habitats. The other species were located along a gradient from the forest to the grassland, matching to the pattern as the closeness and height of the vegetation was decreasing. At the end of the gradient we could find the species aggregating in the dense, high trees and bushes (e.g. Redwing, Nuthatch, Treeccreeper, Chaffinch, Brambling) and at the other end we could find the species grouping in the heterogeneous, bushy grassland (e.g. Whinchat, Whitethroat, Lesser Whitethroat, Willow Warbler, Red-backed Shrike). The species situated between the two ends of the gradient were distributed in a relatively even distribution (e.g. Wren, Chiffchaff, Garden Warbler and Blackcap). During the migration the habitat selection of birds had two main goals: to assure the energy resource required for the continuation of the migration and to avoid the predators. Both goals were served by the strategy to reach the next stopover site as well as the wintering place as soon as possible. The selection of the most appropriate stopover site was done by a third-level decision process including inherited and learned elements as well. The most important key-stimulus was the vegetation structure of the site, the quality and density of the nutrient resources (CODY 1985). During their stopover, some insectivorous species, e.g. the Whitethroat and Lesser Whitethroat chose the scrubs with high sugar content for rest and feeding. Therefore, these species grouped predominantly on more open, shrubby, grasslands that resembled to the savannah wintering areas. Other insectivorous species e.g. Sedge Warbler, Reed Warbler which fed on insects and spiders settled on plants standing in water. Therefore, these birds accumulated on watery, swampy habitats during their migration period. Among the short-distance migratory species, those wintering in the Mediterranean (e.g. Robin) as well as those wintering in Hungary (e.g. Brambling) were continuously present on the study area. The majority of the individuals were staying on the more closed bushy habitats. Their migration was slower, they were spending a longer time on the area than the trans-sahara migrates (e.g. Willow Warbler) therefore avoidance of predators might play a greater role in the selection of rest and feeding sites. The forest and bushy habitats having a denser, closed vegetation structure provided a greater safety against the raptors. 135

136 The migratory birds were maximizing the availability of the next stopover site by minimizing the predation i.e. by choosing the safety. The Bramblings for example, were choosing the feeding sites (fields) with bushy surroundings versus the open spaces because this choice offered more safety against the Sparrowhawk. According to these results, the migration dynamics and habitat selection of the long-distance migratory species exhibited essential differences compared to the short-distance migratory species. These differences were part of an adaptive strategy which was preserved from evolutionary changes. The results of bird ringing project of Tömörd Bird Observatory gave new information for population dynamics, migration route and habitat preference of some bird species migrating over Hungary. Information about connectivity of breeding, resting and wintering areas as well as yearly and daily numbers of populations is crucial information for any conservation (e.g. survey of biotope) and economic (e.g. planning of wind farm) action or widespread transport of disease (e.g. avian influenza). As migration pattern change over time, particularly in relation to factors such as climate change, continued bird ringing is important even for common species (KESTENHOLZ 27). For this reason it would be extremely important to reveal further details about the migration strategy of birds and to get to know the breeding and wintering sites of birds migrating over Tömörd. Thus, we would like to continue our research. 136
