The Status Of The Common Crane (Grus Grus) In Europe - Breeding, Resting, Migration, Wintering, And Protection, Hartwig Prange
Proceedings of the North American Crane Workshop
At present, about 160,000 and 100,000 cranes are migrating on the West-European and on the Baltic-Hungarian routes, respectively, from the northern, middle, and northeastern parts of Europe. On both routes, the resting maxima, simultaneously determined since the 1980’s, has increased three-fold. This increase in migratory cranes is the result of shorter migration routes with higher return rates, a growing passage from the northwestern part of Russia beginning in the 1990’s, and a protected status in the European Union at breeding as well as at many resting and wintering sites. Hence, the cranes learn to find and use new breeding and …

Crop Depredations By Cranes At Daursky State Biosphere Reserve, Siberia, Stephen H. Bouffard, John E. Cornely, Oleg A. Goroshko
Proceedings of the North American Crane Workshop
Crop depredations by staging cranes have been an annual problem at Daursky State Biosphere Reserve in southern Siberia. In September 2001 we met at Daursky when crane populations peaked to investigate the problem and suggest methods to reduce damages. Peak of crane staging coincided with grain harvest. We counted ≈ 30,000 cranes of 5 species, primarily demoiselles (Anthropoides virgo), in the area. Poor grain yields and cooperative farming systems discouraged efforts to reduce damage. Moving crops further from roost areas may be the most reasonable short term control method, but it’s effectiveness is yet untested. Hazing, lure crops …
