Abstract We studied various aspects regarding migration behavior of the Common Buzzard for two subspecies (B. b. buteo and B. b. vulpinus) transiting the region which overlaps with the Western Black Sea Corridor. Using vantage points set across Dobruja we managed to count 2,662 individuals. We highlighted the seasonal and diurnal peak passage, flight directions and height of flight for each season. Our results suggest that 57% of the counted individuals belongs to long-distance migrant Steppe Buzzard - B. b. vulpinus. The peek passage period in autumn migration was reached between the 26th of September to the 6th of October, while for the spring migration peek passage remained uncertain. The main autumn passage direction was from N to S, and NNW to SSE but also from NE to SW. For spring passage the main direction was from S to N but also from ESE to WNW. Flight height during autumn migration was mostly at high altitude while in spring migration was more evenly distributed. The most significant activity was recorded in the second time period, between 10:01 and 13:00 (43%).

AbstractRed Kite shows a great variability in its migration strategies: most individuals in north-eastern Europe are migrants, but there is also a growing number of sedentary individuals. Here, we tagged 49 Red Kites wintering in Spain with GPS/satellite transmitters between 2013 and 2020 to study the autumn and spring migration between the breeding or summering areas in Central Europe and the wintering quarters in Spain. In first place, differences between immatures and adults were found for spring migration. Adults began the spring migration towards the northeast in February–March while the immature individuals began to migrate significantly later and showing a wider date range (February-June). Adults also takes significantly less days to arrive at their destinations (12 ± 5 days) and cover more distance per day (134.2 ± 37.1 km/day) than immatures (19 ± 11 days and 98.9 ± 21.2 km/day). In second place, we also found differences between spring and autumn migration (excluding immatures). Spring migrations were clearly faster and with less stopovers days than autumn migrations. Autumn migration began between mid-October and late November and two different behaviours were observed: most birds made a quick migration direct to the wintering areas with only some days of stopovers, but others prolonged the migration with long stops along the route. These results highlight a great variation in the migratory movements of Red Kite, not only according to age but also between individuals and seasons.

Abstract Kováts D. 2012. Autumn migration of the Thrush Nightingale (Luscinia luscinia) in northernHungary. Ring 34: 23-36. The autumn migration of the Thrush Nightingale was studied in Szalonna in northern Hungary in 1989-2010. Birds were mist-netted, ringed, aged, measured, weighed and fat scored. In total, 193 Thrush Nightingales were ringed during 22 years. Relations between arrival time and biometrical measurements were determined. Within the study period (6 August - 26 September) the migration curve was bimodal showing maximum on 22 August and 27 August. Immature birds arrived significantly earlier with lower body mass and shorter wing length and had more pointed wings in the first half of their passage. The distribution of fat score classes did not differ significantly between the early and late periods of the most intensive migration, although the mean of the deposited fat was the lowest during the peak of migration. Fat reserve distribution was bimodal in autumn suggesting that Thrush Nightingales probably start their journey from different breeding ranges (populations) or follow still undiscovered migration strategies of sex/age groups. The low proportion of recaptures proved that the area was not used as a stopover site or premigratory fattening area. Within 22 years of study, the median date of autumn migration of Thrush Nightingales shifted 7.9 days earlier, probably due to current climate change.

During the spring 2015, a pair of Common Redstarts Phoenicurus phoenicurus successfully raised a five-chick brood in an artificial nest-box designed for and occupied by a pair of Common Swifts Apus apus in southern Sweden. The breeding was monitored by a nest-box camera, which recorded close interactions between the two species. The Common Redstarts initiated the breeding first and had young in the nest when the Common Swifts arrived and initiated breeding by laying their eggs in a nearby nest cup. The breeding overlapped by 15 days between the second and the fourth week of June when all five of the nestlings of the Common Redstart fledged. The Common Swifts raised two young which fledged in early August.
