25-11-2015 JURONG, SINGAPORE - COCONUT LORIKEET (richoglossus haematodus)
%2010.jpg)
Coconut Lorikeets are extremely social parrots. They form small to medium-sized flocks that roost and forage together. They are highly vocal and engage in constant communication with their flock members.
Their bright green and red feathers blend in well with the flowering plants they feed upon, but Lorikeet safety also comes from having their flock on the lookout for predators.
These lorikeets have a specialized diet primarily consisting of nectar, pollen, fruits, and flower buds. Their tongue is equipped with unique brush-like bristles that aid in extracting nectar from flowers and licking pollen from plants. They also have a simplified digestive system that helps them quickly extract sugar from the nectar they eat.
During the breeding season, male Coconut Lorikeets display elaborate courtship rituals to attract females. Once a pair has formed a bond, they search for suitable nesting sites. Their nests are typically constructed in tree hollows. The female lays 1 to 3 eggs, which both parents take turns incubating for 24 to 28 days. Chicks then stay in the nest for about 10 weeks until they are old enough to join the flock.
Coconut Lorikeets are considered Least Concern on the IUCN Red List due to their large area. They have even become an invasive species in some areas, where they compete aggressively for tree hollows. Globally their population is decreasing.

Trichoglossus haematodus is found in eastern Indonesia, on Buru, Seram, Misool, Waigeo, Numfoor, Yapen and the Aru Islands, in Indonesia and Papua New Guinea on New Guinea, in the Bismarck Archipelago, the Solomon Islands, Vanuatu and New Caledonia.
The species occupies a wide range of lowland and wooded hill habitats, including mangroves, rainforest, nypa forest, swamps, savanna and woodland. It also occupies human-modified areas including coconut plantations, gardens, agricultural land and disturbed forest. It is found from sea level up to as high as 2,440 m (8,010 ft); this upper altitude level varies by location.

2-3-2020 KANHA NAT PARK, INDIA - YELLOW THROATED SPARROW (Gymnoris xanthocollis)
The yellow-throated sparrow or chestnut-shouldered petronia (Gymnoris xanthocollis) is a species of sparrow found in southern Asia.
Showing the yellow throat
It has a finer bill than typical sparrows of the genus Passer and unlike them has no streaks on the plumage. The white double wing bar on the shoulder is diagnostic on the otherwise dull grey-brown sparrow. Males have a chestnut shoulder patch which can sometimes be hard to see. They also have a pale yellow spot on the throat in fresh plumage. Females are duller and lack the chestnut shoulder patch. The yellow spot is much reduced or lacking in females.
This species is tree-loving although sometimes seen on wires and on the ground, where it has a hopping gait. The usual call is a chirrup but the song is distinctive and repetitive chilp chalp cholp. It has a bounding flight and dips deeply before rising up.
The species breeds in tree hollows from April to July, often making use of the holes made by primary hole-nesting birds such as barbets and woodpeckers. They may also make use of hollows on buildings. The nest is built mainly by the female, but males may sometimes assist. The female alone incubates the eggs, sometimes leaving the nest during the hotter parts of the day. The eggs hatch after about 12 to 14 days.
They roost communally in low bushes. Some populations are migratory, moving in response to rains.
They feed mainly on grains but also on insects, nectar and berries. An unusual food item is the petals of flowers such as those of Madhuca indica. When they visit flowers such as those of Capparis, Salmalia, Erythrina and Bassia, their foreheads are covered with pollen.
The chestnut-shouldered petronia is found from Turkey into Iran, Afghanistan, Pakistan, India, Bangladesh and as a vagrant in Sri Lanka and possibly parts of Myanmar. It is found in forest, gardens and open scrub habitats.
