“…Here the individuals were in a relatively poor condition, indicating that birds only rest at that site. Here, within the 22 years of study , the median date of autumn migration of Thrush Nightingales shifted 8 days earlier (Kováts 2012). In the same time period, the arrival times also shifted earlier at Ócsa (see later in this paper).…”

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 seventh 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 (1984–2017). First, we give a concise description of foreign ring recoveries of the Thrush Nightingale in relation to Hungary. We then shift focus to data of 1138 ringed and 547 recaptured individuals with 1557 recaptures (several years recaptures in 76 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 present data only for the autumn migratory period since there were only 27 spring captures in the study period. We distinguish the age groups (i.e. juveniles and adults) in the analyses. 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.

“…Sexual dimorphism has been suggested in Lesser whitethroat (Loskot, 2005) and Thrush nightingale (Csörgő et al, 2018), hence, the early and late arrival phases may represent males and females, depicting different migration phenology. However, Kováts (2012) argues that the difference found in wing length in immature Thrush nightingale were not attributed to sex-biased migration timing. Adults may also have longer wings (as we show in Lesser whitethroat and Thrush nightingale).…”

Time to Move On: The Role of Greenness in Africa and Temperatures at a Mediterranean Stopover Site in Migration Decision of Long-Distance Migratory Passerines

Many migratory species have advanced their migration timing as a response to advanced breeding conditions. While data on arrival timing to breeding grounds in Europe is plentiful, information from the African departure sites are scarce. Here we investigated changes in arrival timing of four long-distance migratory passerines to a stopover site in Israel and potential links to Enhanced Vegetation Index (EVI) at the species-specific African pre-departure sites and local temperatures at the stopover site. We found that Lesser whitethroat (Curruca curruca) and Eastern Bonelli’s warbler (Phylloscopus orientalis) advanced arrival to the stopover site. The arrival timing of Thrush nightingale (Luscinia luscinia) and Olive-tree warbler (Hippolais olivetorum) did not change and was associated with mean EVI at the pre-departure site in Africa during the pre-migratory period. Additionally, temperatures at the stopover site affected the arrival timing of Lesser whitethroat only. This is probably because this species breed at higher northern latitudes and fine-tune their migration timing to match local conditions. Our results show that spring migration can be influenced by exogenous cues such as weather condition and food availability, and the level of response is species-specific. Moreover, some species show flexibility and fine-tuned migration speed in response to local conditions en route. While flexibility seems advantageous, dependence on multiple sites with varying conditions may ultimately limit advanced arrival to the breeding ground and result in mismatch with optimal conditions.

“…We found a significantly longer wing length in spring than autumn despite the postnuptial moult, so Common Nightingales migrating through the Carpathian Basin probably belong to loop-migrating populations. In case of its sister species -the Thrush Nightingale (Luscinia luscinia) -the existence of loop migration pattern has already been detected by Kováts (2012).…”

Bird species following a loop migration strategy use different routes during autumn than in the spring season. Birds nesting at different latitudes have different wing morphology. Finding significant differences in the average wing lengths of the same species between the autumn and spring seasons in the same area suggests loop migration. If these differences are also different by sex, this suggests that males and females do not use the same migratory routes. In this study, we analysed wing morphological differences of seven common long-distance migrant passerine species ringed at the Ócsa Bird Ringing Station from 1984 to 2014. Species were divided into three groups based on moult strategies (pre-, postnuptial and double moult). Based on differences in wing length distributions and means between autumn and spring, six of the seven passerine species follow loop migration. While wing length differences can be adequate to detect loop migration, the species specific moult strategies, the nesting sites and distribution ranges need to be known.
