Concervation is an alternative way to save this species from being extinct. The objective of this research was to fnd out the comparison of daily behaviour between male and female Brahminy Kite at Ragunan Zoo- Jakarta such as three activities. These behaviours were motionless, movement and ingestive. The descriptive method was used in this study, by direct observation to the behaviour of individual bird. The focal animal sampling was used as a method for recording behaviour, which means observing one individual for a specifed amount of frequence and recording all instance of its behaviour. The observation was carried out on 2 birds with sex male and female. Each individual’s bird was observed each day from 06.00 to 18.00. Data analysis used descriptive analysis and nonparametric statistics analysis with U Mann-Whitney Test. The result of this analysis indicated if there were comparison of motionless behaviour and movement behaviour between male and female Brahminy Kite, where testing criteria Eject H 0 , density is 0.00 < α, level was signifcance but there was not comparison of ingestive behaviour between male and female Brahminy Kite. Density is 0.38 > α,level was insignifcant Keyword : the comparison, daily behaviour, Brahminy Kite, Ragunan zoo PENDAHULUAN Elang Bondol merupakan burung yang termasuk ke dalam kategori pemangsa. Di dalam ekosistem, burung pemangsa menempati posisi sebagai pemangsa puncak dan memegang peranan penting untuk mengontrol populasi mangsanya.
