—About 50% of the world range of the Gyrfalcon (Falco rusticolus) is in Russia, with the highest density in the southern Yamal, and the largest numbers located in Kamchatka. The main source of information on Russian Gyrfalcons is the monograph “Gyrfalcons” by Dementiev, published in 1951 and later translated into German and English. Analysis of Russian literature on the Gyrfalcon for the second half of the 20th Century was undertaken by E. Potapov and R. Sale in their joint monograph “The Gyrfalcon,” published by Poyser in 2005. In the mid-1990s, I prepared for the company of Dr. Nick Fox an annotated bibliography in English on the Gyrfalcon in the territory of the ex-USSR, available free upon request. The list includes 490 entries on 64 pages, predominantly in Russian, covering the period 1656–1995. The majority of entries include episodic observations during avifauna investigations of vast areas, and only 25 articles and species accounts are dedicated exclusively to the Gyrfalcon. Following the collapse of the USSR, visits to arctic regions declined, poaching developed, and long-term studies on the Gyrfalcon became almost impossible due to a shortage of funds. However, a number of important publications have appeared and are available, along with other information, on the Internet in both Russian and English. Most of the literature deals with breeding biology, descriptions of breeding sites, and other observations, whereas other aspects of biology and ecology are insufficiently studied. Absence of work on post-breeding movements, winter ecology and taxonomy is apparent. Received 28 February 2011, accepted 28 June 2011. SHERGALIN, J. 2011.
