Interspecific correlations toward climatic factors in migratory raptor species across Mt. Sega, Karangasem, Bali

It has been known that climate change can affect organisms in various ways. For example, studies found that climate change affect phenology i.e. migratory arrival of migratory species. This study was aimed to find out whether the migratory arrival of five species of bird of prey flying across Mt. Sega Karangasem – Bali correlates with climate factors in the region. This study took place from 1 October to 30 November 2018 by using look up method, and found that air temperature, cloud cover, humidity, and air pressure had a stronger correlation toward the migratory bird of prey species that crossed over the Mt. Sega compared to wind speed and precipitation. The air temperature, cloud cover and wind speed had a positive correlation toward the migratory bird of prey arrival, whereas the negative correlation was demonstrated by humidity, air pressure, and precipitation. The presence of the Chinese Sparrow-hawk and the Short-toed Snake Eagle were correlated with the humidity. Whereas the presence of the Peregrine falcon was correlated with the cloud cover. The presence of the Oriental Honey Buzzard was correlated with the wind speed, while the precipitation and air pressure were correlated with the presence of the Japanese Sparrow-hawk. The Japanese Sparrow-hawk arrived earlier at 10.00 whereas the other four species arrived later at around 12.00.
