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 50,000 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 1990). 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 2007).
Palearctic-African migratory bird populations have to defeat several ecological barriers, like seas and deserts during the migration in post-breeding 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 2002).
Many species of European bird species are currently undergoing rapid declines, but some birds have increasing and expansive populations (BIRDLIFE 2004). 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.

Bird ringing for scientific purposes started in Hungary in 1908, 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-20. century when mist-nets 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 2000). 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 2007). 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 1000 years – is confronting us with so

many rapid changes in the phenomenology of bird migration that we can hardly keep up with recording and analyzing them (BERTHOLD et al. 2003). In this publication the autumn migration of birds captured in the Bird Ringing Project of Tömörd Bird Observatory between 1998 and 2007 is characterized. A total of 49619 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 area and methods
Study site and field work
The birds were captured and ringed at the Tömörd Bird
Observatory (47°21'23"N 16°40'04"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 August to the end of October or early November (Table 1).

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 200) (See below).
Forest (W.LB6N0.2EUPR.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.BH2N0.2PRCR.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.TC1S0.0.R.). Characteristic plants were Glyceria maxima, Typha latifolia, Salix cinerea. It was dried out in 2000 and 2001.
11
There was 0.5-1 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 0.1 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 (2000) ranging from 0 (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 χ2-test for the year with the most captures.

Sites of ringing and sites of recovery were delineated on a map for all the birds ringed abroad or at other Hungarian ringing sites and recovered in Tömörd and also those ringed in Tömörd and recovered abroad or at other Hungarian ringing sites (Photo 6).

Linear regression of yearly captures, r=0.67, p<0.05
The course of the catching dynamics was very similar for years and age groups, Kruskal-Wallis test, p>0.05. On average, migration of the
35
Robin started on the 24th of August (the earliest 27 July, the last 22 September). The average median date of the passage was 3 October. The average date of the end of migration was 15 November. The date of the last capture was 18 November. The peak period of migration fell on the end of September and mid-October in the years 1998-2007. The most captures occurred in October (Fig. 26). The apparent shift of the beginning of autumn migration towards earlier date was not significant in the years 1998-2007, Pearson’s r=-0.34, p>0.05 (Fig. 27).
The proportion of recaptured birds was 16-39%, however, it significantly varied from year to year. Majority of Robins spent only a short time, whereas some Robins spent a longer time in the area. The mean minimum stopover time of recaptured birds was 4.2 ± 4.94 days, the maximum was 64 days. Local breeding birds ringed in August left the study area by the end of September (Fig. 28).
The Robins were grouping in the bushy areas, the width of their habitat was small compared to other species (GYURÁCZ et al. 2005). 49 per cent of the Robins were captured in the bushy in 2007, χ2=2, p>0.05 (Fig. 29). Individuals captured in the bushy were fatter than those captured in the forest, grassland and marsh (ANOVA, p<0.01) (Table 4). The most of the Robins ringed in Tömörd probably wintering in Italy (Table 5).

Fig. 102. Yearly capture numbers of Willow Warblers
On average, migration of the Willow Warblers started on the 19th of
August (the earliest 5 August, the last 3 September). The average median date of the passage was 9 September. The average date of the end of migration was 12 October. The date of the last capture was 14 October. The peak period of migration fell on the early September in the years 1998-2007. The most captures occurred in September (Fig 103). The apparent shift of the beginning of autumn migration towards earlier date was not significant in the years 1998-2007, Pearson’s r=-0.53, p>0.05 (Fig. 104).
Proportion of recaptured birds was 20% in 2005. The minimum stopover time of the recaptured individuals was min. 2, max. 20 days in 2005 (Fig. 105). 80 per cent of the Willow Warblers were captured in the grassland in 2005, χ2=6, p<0.05 (Fig. 106). Some Willow Warblers probably migrated probably to SW from Tömörd (Table 15).

The seasonal dynamics of sexes was somewhat different in 2000
and 2001. It seemed that the share of males increased during peak period of migration (Fig. 109) (GYURÁCZ et al. 2003a). The apparent shift of the beginning of autumn migration towards earlier date was not significant in the years 1998-2007, Pearson’s r=-0.45, p>0.05 (Fig. 110). Proportion of recaptured birds was 5-8% in the years 2000-2006. The minimum stopover time of the recaptured individuals was min. 2, max. 26 days in 2004 (Fig. 111). 64 per cent of the Goldcrests were captured in the bushy, χ2=2, p>0.05 (Fig. 112). The most Goldcrests migrating above Tömörd probably originated probably from the Baltic region and NW Russia (Table 16).

On average, migration of the Blue Tits started on 25 August (the earliest 9 August, the last 1 September). The average median date of the passage was 2 October. The average date of the end of migration was 8 November. The date of the last capture was 11 November. The peak period of migration fell on the end of September and early October in the years 1998-2007. The most captures occurred in October (Fig. 136). Proportion of recaptured birds was 5% in 2004, 13% in 2005 and 15% in 2006. 62 per cent of the recaptured birds were male (Fig. 137). According to the distribution of recaptures, the local breeding birds captured in August stayed until early November and probably overwintered at the study area. The most of birds arrived in the peak migration period left the area quickly by the end of October (Fig. 138). 68 per cent of the Blue Tits were captured in the grassland, χ2=2, p>0.05 (Fig. 139). The migratory Blue Tits probably followed SSW direction from Tömörd and wintered at the Adriatic region (Table 19).

91. Great Tit (Parus major) The Great Tit was dominant songbird in the study area. In total, 2843 individuals of Great Tits were marked between 1998 and 2007. The most birds were captured in 2005, the least in 1998. The average daily captures changed significantly, Kruskal-Wallis test, H=67.99, p<0.0001 and the yearly captures showed significant increasing trend from 1998 to 2007 (Fig 140). Significant positive correlation was found between the yearly numbers of males and females (Fig. 141). Significant negative correlation was found between the ratio of first-year birds (production) and the number of adults in a specific year (Fig. 142).
On average, migration of the Great Tits started on 26 September (the earliest 1 August, the last October). The average median date of the passage was 13 October. The average date of the end of migration was 8 November. The date of the last capture was 16 November. The peak period of migration fell on mid-October in the years 1998-2007. The most captures occurred in October (Fig. 144).

Proportion of recaptured birds was 9% in 2004, 15% in 2005 and 22% in 2006. According to the distribution of recaptures, the local breeding birds captured in May and August stayed until early November and probably overwintered at the study area (Fig. 145). 65 per cent of birds recaptured in November were male (Fig. 146). The most of birds arrived in the peak migration period left the area quickly by the end of October. 45 per cent of the Great Tits were captured in the grassland, χ2=0, p>0.05 (Fig. 147). Some migratory Great Tits probably wintered in Slovenia and Croatia (Table 20).

Summary and discussion From the 118 species ringed in Tömörd between 1998 and 2007 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.

Fig. 199. 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 2007. 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 2007. The yearly number for Grasshopper Warbler showed a negative trend between 2003 and 2007. There was a Blue Tit and Bullfinch invasion in 2004. The number of Chaffinchs, Bramblings, Hawfinchs and Greenfinchs ringed in 2005 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 2003 was the highest because of the plenty of grain of wheat around Tömörd in that period. The marsh dried out in 2000 and 2001. For this reason the smallest number of Sedge Warblers, Marsh Warblers and Reed Warblers were ringed in those years.
134
The migration curves based on the average number of individual species ringed daily between 1998 and 2007 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 August and terminated it in early October. On average, the migration of five species, Swallow, Marsh Warbler, Whitethroat, Lesser Whitethroat and Thrush Nightingale started earliest in the first half of August. Most of trans-Sahara migratory birds left the study area by October. The migration of the second group commenced in the last part of August and September and might last until the end of October and early November (e.g. Wren, Dunnock, Robin, Redstart, Chiffchaff and Great Tit). The third group included the short-distance and vagrant species with migration commencement in October and migration termination by the end of October and early November (e.g. Blackbird, Song Thrush, Goldcrest and Reed Bunting). Based on the monthly data, October was the migration peak period for the three dominant and short-distance 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. 2003).. Sedge and Reed Warblers and other long-distance migrants migrated over Hungary in August and September 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 short-distance migrants, e.g. Robin, Blackcap, Chiffchaff, Goldcrest and Blue Tit (GYURÁCZ et al. 2003b). 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
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.
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 2007). 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.
