Abstract
Singing behavior is shown by many animals during intraspecific interactions, such as during territorial marking, playing and directing others. Gibbons are known for their loud and elaborate songs in the early morning starting from sunrise. These calls average 11 minutes and can be heard up to one kilometre only as their habitat is high canopy. Studies show early mornings provide the best conditions for sound transmission but weather can have a large influence on how sound travels through the environment. The purpose of this study is to determine the effect of weather in early mornings on the singing behavior of the gibbons. In this study, we qualitatively assess gibbon singing behavior in relation to weather changes. The singing behavior in wild gibbons was studied in the early morning starting from 7am until 11am at Taman Negara Kuala Tahan, Pahang. The duration of the singing was documented and the condition of the weather, temperature and humidity in the morning and the night before were recorded. Over the five periods of investigation, wild gibbons started their singing around 9am. If there was rain the previous night or early morning, gibbons started singing at a later time around 11am or when the sun was visible. Those results indicated that there is an association between weather and gibbons’ singing behavior pattern. The results are in line with previous studies from Dena J.Clink in Sabah that show that changes in overnight conditions and weather can influence early morning calling behavior and time it starts calling.
