The Effect of Weather on the Distribution of Kittiwakes and Fulmars in the North Atlantic

  • Stanisław MANIKOWSKI

Abstract:

The role of different external factors in the distribution of Kittiwakes and Fulmars was examined on the basis of materials collected during two passages across the Atlantic (8 days. 82 observations) using multivariate statistics. The rise in the number of Kittiwakes during observations correlated with the increase in the wind speed, the state of sea, and southerly winds. The greatest numbers of Kittiwakes were observed in February and then especially in the afternoon. The distribution of Fulmars correlated with the geographical longitude and the passage of occlusions.
