Count Results & Prospects

The results of BRC 2008 and 2009 are further discussed in an international context of breeding populations and bottleneck areas in the Black Sea basin in an upcoming publication. A link to this article will be submitted upon publication.  In summary the Batumi bottleneck is a key component in the flyways of many of the Eurasian migratory raptor species. Average recorded numbers for 10 of these exceed 1% of the estimated world population.

At Batumi the exclusion of some species for monitoring appears very strange from a birdwatchers perspective because some may constitute an important portion of the total migration. We repeat here that it is important to realize that monitoring is all about long-term effort and that data on migratory species must always be regarded in an international context! This means that some species will not be eligible to ´monitor´ because of practical difficulties or the value of localized counts relative to breeding numbers or numbers of migrants at other watch-sites.

The autumn migration consists mainly of Honey-buzzard (Pernis apivorus, ca. 400,000 each autumn) and Steppe Buzzard (Buteo buteo vulpinus, 250,000+), both with daily totals peaking at 60,000 - 80,000 ind. Other numerous species include Black Kite (50,000+), [...] , Montagu´s (C. pygargus, 3,000+) and Pallid Harrier (C. macrourus, 1,000+ ) ...
