Zebra dove (Geopelia striata)

Perkutut or zebra dove (Geopelia striata) is a species of animal in the Columbidae, a monomorphic, grain-eating bird, although may also eat insects and small invertebrates, blue iris, black and white stripes are cut off by light brown on the thorax and abdomen.

G. striata has a length of 21 cm, slender and a long tail. Gray head and neck, smooth striped sides and brown back with black edges. The tail is blackish with a white tip. Bluish gray iris and beak, dark legs.

Zebra doves live in pairs or small groups. Prefers open fields for eating at ground level in forests, gardens, parks, farmlands, pastures, yards and sometimes gather to drink at water sources.

The nests are flat and thin, built using branches in the canopy of large trees and sometimes not far from settlements, although they will quickly fly away if humans arrive. Eggs are white, 2 items and breed in January-September.

Perkutut are unique in their beautiful songs and have been the favorite birds of kings in Java since the Majapahit Kingdom. Voices generally consist of front, middle and end sounds. Waveform analysis shows males pass on the front sound and number of beats to their offspring, while females pass on the end sound and give a touch of rhythm.

G. striata that is farmed is usually fed only grains including white millet, red millet, millet, small grain and black sticky rice. Sometimes also canary seeds, godem seeds, mustard seeds and cuttlefish bones for mineral needs.

Yellow garden spider (Argiope appensa)

Yellow garden spider ( Argiope appensa ) is a species of spider in Araneidae that lives on the coast to forests on islands in the western Pacific Ocean. Black and yellow females are striking and have a length of 5.1-6.4 cm including long legs, while males are brown and have a length of about 1.9 cm. A. appensa lives on cliffs in the hills at 600 m above sea level in Kewu plain to rice fields in the lowlands. They make nests at a height of 1.5 meters from the ground between teak ( Tectona grandis ), sonokeling ( Dalbergia latifolia ), sonosiso ( Dalbergia sissoo ), crown flower ( Calotropis gigantea ) and various grasses. Yellow garden spiders grow in large sizes, but are not toxic to humans. Advanced builds ball-shaped nets and most of them make stabilizers which are zigzag-shaped lines in nets made of thicker bands. This species spends more time in stationary and sits in the middle of the net with its head down to wait for insects to be entangled in fine silk thread. Unli...

Skyflower (Duranta erecta)

Sinyo nakal or skyflower ( Duranta erecta ) is plant species in Verbenaceae, a broad shrub or small tree, up to 6 m high, stems growing upright or horizontally with broad clumps, many branches, bark light brown, old tree has axillary spines and grows to form dense colonies. D. erecta has bright green leaves, elliptical to ovoid, pointed or rounded ends, sitting opposite, 7.5 cm long, 3.5 cm wide, a main vein in the middle with several small lateral veins, petiole long 1.5 cm. Flowers are light blue or lavender or white, appear in tight clusters as on terminal stems and axils, often curled or pendulous, blooms in summer. The fruit is a berry having a stalk, small round, yellow or orange or white in color, up to 11 mm in diameter, an eye green in front and containing several seeds.

Big-leaved acacia (Acacia mangium)

Big-leaved acacia ( Acacia mangium ) is a species of woody plants in the Acacieae, long oval leaves, growing up to 30 m and straight stems, except in less favorable places will grow only 7-10 m, have hardwood, rough, longitudinal grooved and dark to light brown. A. mangium has shoots with compound leaves consisting of many minor leaves and after growing a few weeks does not produce any more real leaves but the main axis of the petiole of each compound leaves widens and turns into known pohyllocladus or pseudo leaves. Big-leaved acacia has about 142,000 seeds/kg. Long pods form circular threads and are black or brown when ripe. Dry pods will open to expose small black seeds. Trees bind nitrogen to the soil and are a popular species for agroforestry projects. This plant is weather resistant, although it requires special care if it is planted as a garden plant where the leaves are falling a lot. These plants include legumes that grow quickly by increasing height 4 m per year near ...
