Abstract

Kakaktua Tanimbar (Cacatua goffiniana) merupakan spesies burung endemik di Kepulauan Tanimbar, Provinsi Maluku yang saat ini eksistensinya terancam akibat degradasi habitat, perburuan, dan perdagangan ilegal. Spesies ini telah diintroduksi ke berbagai wilayah seperti Singapura, Taiwan, dan Jepang, serta baru-baru ini ditemukan hidup liar di Taman Margasatwa Ragunan. Penelitian ini bertujuan untuk mengetahui jenis pakan dan karakteristik sarang C. goffiniana liar di Taman Margasatwa Ragunan sebagai bagian dari upaya memahami potensinya berkembang menjadi spesies naturalisasi. Metode yang digunakan dalam penelitian ini adalah deskriptif dengan teknik purposive sampling. Jenis pakan dan karakteristik sarang dicatat menggunakan metode ad libitum tanpa menggunakan batasan waktu atau interval. Data dikumpulkan melalui observasi langsung terhadap individu liar di lapangan. Analisis data dilakukan secara deskriptif dan disajikan dalam bentuk tabel serta diagram. Kurva akumulasi spesies juga digunakan untuk mengevaluasi keragaman jenis pakan alami. Hasil penelitian menunjukkan bahwa C. goffiniana liar mengonsumsi pakan alami yang berasal dari 13 spesies tumbuhan, dengan bagian yang dikonsumsi meliputi buah (56,81%), biji (22,74%), daun (9,09%), batang (9,09%), dan bunga (2,27%). Semua individu bersarang pada spesies pohon Falcataria falcata dengan rata-rata tinggi pohon 26,38 m; tinggi sarang 17,36 m; diameter pohon 0,87 m; dan nilai NDVI 0,41. *****The Tanimbar Corella (Cacatua goffiniana) is an endemic bird species from the Tanimbar Islands, Maluku Province, whose existence is currently threatened by habitat degradation, hunting, and illegal trade. This species has been introduced to various regions such as Singapore, Taiwan, and Japan, and was recently discovered living in the wild at Ragunan Zoo. This study aimed to identify the diet composition and nest characteristics of wild C. goffiniana at Ragunan Zoo as part of an effort to understand their potential to become a naturalized species. A descriptive method was used, with purposive sampling to determine observation locations. Diet composition and nest characteristics were recorded using the ad libitum method, without time or interval constraints. Data were collected through direct observation of wild individuals in the field. The data were analyzed descriptively and presented in tables and diagrams. A species accumulation curve was also used to evaluate the diversity of natural food sources. The results showed that wild C. goffiniana consumed natural food from 13 plant species, with the consumed parts consisting of fruits (56,81%), seeds (22,74%), leaves (9,09%), stems (9,09%), and flowers (2,27%). All individuals nested on Falcataria falcata trees, with an average tree height of 26,38 m; nest height of 17,36 m; tree diameter of 0,87 m; and an NDVI value of 0,41.
