Migración de Ictinia mississippiensis por el Cabo de San Antonio, Reserva de la Biosfera, Península de Guanahacabibes, Cuba

Resumen

Ictinia mississippiensis migration in the most western part of Cuba is characterized through permanent observations on 12 hr daily average, since mid-July until mid-November between 2012-2015 and using the information about the different meteorological variables in the Cabo de San Antonio Met Station. The migratory phenology of the specie is described during the study period. The monthly relative abundance exposed the maximum value in September and the time interval dynamic described two picks of maxim detectability, one of them between 08:00 y 09:00 hr and the other between 15:00 y 16:00 hr. A correlation analysis of the relative abundance with the meteorological variables offered positive significance with clouds concentration (r=, 074(**)), increase of the minimum and maximum temperature 6 hours before (r=, 106(**) and, 113(**)) and the storm r=, 108(**), while the presion and the temperature (r= -, 077(**) y -, 067(**) affected the abundance indicator.
