Spring migration of the White Stork,Ciconia ciconia, and the Black Stork,Ciconia nigra, over the Bosphorus

Dynamics of Naïve White Storks Ciconia Ciconia Migrating at the Central European Migratory Divide during 1947–2018

“…Virtual lack of recoveries of young storks from the Czech Republic on the western flyway prior 2003 can hardly be explained by low searching effort for Storks by professional ornithologists (Tortosa et al 1995, Archaux et al 2004, Schaub et al 2004, Catry et al 2017). We do not see any clear indication of decreasing interest in White Stork migration among academics on the eastern migration route either (Berthold et al 2001, van den Bossche et al 2002, Arslangündoğdu et al 2011, Alon et al 2014, Bairlein et al 2014). However, recovery rates are largely determined by reporting by the public.…”

Soaring Bird Migration Research at the Bosphorus Strait, Turkey

“…As in the Balkans the main wind direction is from the North, with about 15% of winds from the South (Arslangündoğdu et al, 2011 have been found to be much more concentrated in one area between Sariyer and the Black Sea with winds shifting them a short distance north or south. Wind from the north tended to blow all species of birds a little further south.…”

“…A week-long observation done in APPLIED ECOLOGY AND ENVIRONMENTAL RESEARCH 16(6):7953-7968. Hungary 2002 (MME, 2007) showed a notable peak on 15/4(2,143). The first peak was in the third period(12)(13)(14)(15)(16) of five day periods in 2007, while 2nd peak was determined in the 9th period (07-11 April) (Fig.3c).…”
