Saxaul sparrow

The saxaul sparrow (Passer ammodendri) is a passerine bird of the sparrow family Passeridae, found in parts of Central Asia. At 14–16 cm (5.5–6.3 in) and 25–32 g (0.88–1.13 oz), it is among the larger sparrows. Both sexes have plumage ranging from dull grey to sandy brown, and pale brown legs. The female has a less boldly coloured plumage and bill, lacking the pattern of black stripes on the male's head. The head markings of both sexes make the saxaul sparrow distinctive, and unlikely to be confused with any other bird. Vocalisations include a comparatively soft and musical chirping call, a song, and a flight call. Its distribution falls into six probably disjunct areas across Central Asia, from central Turkmenistan to northern Gansu in China. A bird of deserts, the saxaul sparrow favours areas with shrubs such as the saxaul, near rivers and oases. Although it has lost parts of its range to habitat destruction caused by agriculture, it is not seriously threatened by human activities. (Full article...)

Amblyeleotris rubrimarginata

Amblyeleotris rubrimarginata is a fish in the family Gobioidei, the gobies. It is found on reefs or in seagrass beds in the western Pacific, from New Caledonia to the Great Barrier Reef and around New Guinea, Indonesia, Malaysia and the Philippines, at depths from 3 to 26 metres (10 to 85 ft). As with other Amblyeleotris species, it has a symbiotic relationship with alpheid shrimps, with an individual or a pair of gobies sharing a burrow with a pair of shrimps. A. rubrimarginata is up to 8 centimetres (3.1 in) in length, and its background colour is whitish, marked with five vertical brown or orange bars. It is most readily distinguished from its congeners by a row of red spots along the margin of both dorsal fins and the upper part of the caudal fin, and also by a prominent black spot just above and behind the eye. This A. rubrimarginata fish was photographed at the resort of Anilao in Mabini, Batangas, in the Philippines.
