Data on the Wintering of the Rook, Corvus frugilegus Linnaeus, 1758 (Aves: Corvidae) in Plovdiv, Bulgaria
Journal Title: Ecologia Balkanica - Year 2014, Vol 6, Issue 2
Abstract
In the current study we report a short summary on the wintering of the Rook in the town of Plovdiv. During our field study we estimated that no less than 29 706 ± 8722 Rooks are roosting in Plovdiv. Our findings revealed that the number of wintering individuals of this species has increased in a ten years period by 35 times in comparison to a previous study and reached a maximum in February when 59 280 Rooks were counted. Further investigation on that matter is needed so that the wintering pattern of the Rooks could be revealed entirely.
