Summary: | The aim of the investigation was to determine possible participation of birds in maintaining an episootic process within a natural focus. The data collected show that in Kirov Oblast taiga tick larvae and nymphs are regularly found on 8 or 9 bird species. Abundance indices of ticks on tree pipits and pine bunting (birds most frequently attacked by larvae and nymphs), only increase during certain years. The density of the bird tick host population remains disproportionately lower than the rodent density. There was a positive hemagglutination inhibition reaction in about 10% of sera obtained from birds. Birds play an insignificant role as hosts of ixodid ticks and virus circulation in eastern European natural foci of tickborne encephalitis. Trans. of Mater. Konf., Omsk, December 10-13 1963.
