“…In general, our results are in contrast with Western and Central European studies, for example in [14][15][16], where trends in first arrival seem much greater than reported here. There is an increasing body of evidence that these species are returning earlier throughout their range [2,7,14,17].…”

Abstract:The timing of when migrant birds return to breed is a key component of studies of the impact of climate change upon bird populations.However, such data are not distributed evenly across the World, and in the Northern Hemisphere are underrepresented in Asia and the east of Europe. Therefore, to help rectify this bias, we analysed first arrival dates (FAD) of four species of Sylvia warblers (Blackcap Sylvia atricapilla, Whitethroat S.communis, Lesser Whitethroat S.curruca and Garden Warbler S.borin) collected in the Tatarstan Republic of Russia between 1957 and 2008. Over the whole period the species returned to their breeding sites between three and six days earlier; these trends were significant except for Whitethroat. Advances in arrival were especially apparent in the two earlier species, Blackcap and Lesser Whitethroat, mainly because local temperatures for March had risen substantially. Except for Whitethroat, FADs were significantly related to temperatures in the African wintering ground and/or in Tatarstan. Whilst significant correlations occurred between FADs of some of the species, there was considerable variability in these relationships indicating a species-specific response to rising temperatures. Changes in FADs in this eastern extremity of Europe were smaller than in Central and Western Europe.

“…While only a marginally significant trend toward earlier first arrival dates was observed in western Poland during the period of 1913-1996(Tryjanowski et al 2002, it was significant between 1983-2003 (Tryjanowski et al 2005). The same trend in FAD could be observed in the second half of 20 th century (Sparks et al 2007) and in median passage dates between 2002-2011 in the UK (Eddowes 2012). Opposite trend was detected in Spain, where Nightingales showed a marked tendency to delayes arrival at the second half of 20 th century (Gordo et al 2005).…”

Ornithological studies often rely on long-term bird ringing data sets as sources of information. However, basic descriptive statistics of raw data are rarely provided. In order to fill this gap, here we present the fifth item of a series of exploratory analyses of migration timing and body size measurements of the most frequent Passerine species at a ringing station located in Central Hungary (1984–2016). First, we give a concise description of foreign ring recoveries of the Common Nightingale in relation to Hungary. We then shift focus to data of 3892 ringed and 1499 recaptured individuals derived from the ringing station, where birds have been trapped, handled and ringed with standardized methodology since 1984. Timing is described through annual and daily capture and recapture frequencies and their descriptive statistics. We show annual mean arrival dates within the study period and present the cumulative distributions of first captures with stopover durations. We present the distributions of wing, third primary, tail length and body mass, and the annual means of these variables. Furthermore, we show the distributions of individual fat and muscle scores, and the distributions of body mass within each fat score category. We distinguish the spring and autumn migratory periods and breeding season and age groups (i.e. juveniles and adults). Our aim is to provide a comprehensive overview of the analysed variables. However, we do not aim to interpret the obtained results, merely to draw attention to interesting patterns that may be worth exploring in detail. Data used here are available upon request for further analyses.

“…Migrant arrival data from local groups has been found to be reliable in previous phenological studies (Both and Visser, 2001;Cotton 2003;Sparks et al 2007). Data in the RSPB records were from standardised point counts and roving records (methods as per Bibby et al 2000).…”

“…Moreover, FADs correlate positively with mean arrival date for species where the latter can be calculated Tøttrup et al 2006) and have been widely used to determine temporal change in migration (e.g. Sparks, 1999;Both and Visser, 2001;Butler, 2003;Cotton 2003;Sparks et al 2007). Analysis of FADs is particularly robust for analysing temporal change for the same population 72 (as here) (Tryjanowski et al 2005).…”
