We drove for about 290 km through the 400 square kilometres expanse of Pancevacki Rit and found 8 breeding colonies with 252 occupied nests, or a density of 1.6 And what is the trend of those Belgrade rookeries? Two years ago, I was counting active nests of Rooks in the flat agricultural landscape north of Belgrade, Serbia.

Data were collected from the North American Breeding Bird Survey and the Pan-European Common Birds Monitoring Scheme. The trend in CII is positive and similar in the two regions. On both continents, interspecific and spatial variation in population abundance trends are well predicted by climate suitability trends.

The authors’ detailed delineation of problems with the accuracy of NYC breeding bird surveys or with the limits of historical writings may test a reader’s patience.

With regard to the Grey-backed Thrush , “further research should focus on identification of nest predators, implications of nest exposure and begging calls on nesting success, and breeding habitat requirements at different spatial and temporal scales of Grey-backed Thrush in fragmented landscapes of northeast China.”

Unfortunately, the Ashy Drongos did not exactly do what he predicted that they would do – mob potential predators more frequently during the breeding season and mob the more dangerous predator (in this case, the Black Eagle) more intensely.
