The first report of syllable analysis of the chattering lory (Lorius Garrulus (Linnaeus, 1758)) in the crooked beak sanctuary of Koli Village, Tidore Islands City, North Maluku

Abstract

The Chattering lory is an endemic bird with a restricted range in North Maluku. The crooked-beaked bird is one of the world's most popular types of domesticated birds, which negatively affects its long-term viability. The population estimate for chattering lory birds is between 46,360 and 295,540 heads. Poaching is the most significant factor contributing to population decline. An estimated 16,000 chattering lory are captured and sold annually. This study intends to analyze the syllables of bird sounds, as bird-sound-related research is still uncommon. The data collected from a Voice Recording of the chattering lory (Lorius garrulus) was then analyzed using Avisoft-SASlab Lite software. This study was conducted by recording bird sounds. The recording process (Analog Recording) is carried out within a specific time interval to record the birds' sounds multiple times. Bird sounds are recorded in the morning (07:00 to 10:00 WIT). The results indicated that the chattering lory's 131.4-second-long call consists of 18 syllables and four elements. The duration of a syllable varies from 0.51 to 0.66 seconds, and the duration between syllables ranges from 1.31 to 16.09 seconds. Also, the variable is the frequency of each upper and lower element. The lower element's frequency ranges from 100 to 12,100 kHz, while the upper element's frequency ranges from 1,500 to 18000 kHz.
