Tourterelle tigrine
Spilopelia chinensis
Un oiseau de jardin commun dans une grande partie de l'Asie, que l'on trouve dans les forêts ouvertes, les champs et les parcs ; introduit dans plusieurs régions du monde. Souvent apprivoisé et approchable. Brun dans l'ensemble avec une poitrine rosée et une tache noire unique tachetée de blanc sur la nuque. Le plumage présente de légères variations régionales : les oiseaux de l'ouest ont des centres sombres aux plumes des ailes, absents chez les oiseaux de l'est. Les tourterelles sont plus grandes, ont des centres noirs aux plumes des ailes et des rayures plutôt que des taches sur le cou. Roucoule fort et souvent : « coo-a-roooo ».
Identification
The ground colour of this long and slim dove is rosy buff below shading into grey on the head and belly. There is a half collar on the back and sides of the neck made of black feathers that bifurcate and have white spots at the two tips. The median coverts have brown feathers tipped with rufous spots in the Indian and Sri Lankan subspecies which are divided at the tip by a widening grey shaft streak.<p>The wing feathers are dark brown with grey edges. The centre of the abdomen and vent are white. The outer tail feathers are tipped in white and become visible when the bird takes off. Sexes are similar, but juveniles are duller than adults and do not acquire the neck spots until they are mature. The length ranges from 28 to 32 centimetres (11.2 to 12.8 inches).<p>Abnormal plumages such as leucism can sometimes occur in the wild.
Taxonomie
The spotted dove was formally described in 1786 by the Austrian naturalist Giovanni Antonio Scopoli and given the binomial name Columba chinensis. This species was formerly included in the genus Streptopelia. A molecular phylogenetic study published in 2001 found the genus was paraphyletic with respect to Columba. To create monophyletic genera the spotted dove as well as the closely related laughing dove were moved to the resurrected genus Spilopelia that had been introduced by the Swedish zoologist Carl Sundevall in 1873. Sundevall had designated Columba tigrina as the type species, a taxon that is now considered a subspecies of the spotted dove.<p>Several subspecies have been proposed for the plumage and size variation seen in different geographic populations. The nominate form is from China (Canton), which is also the origin of the introduced population in Hawaii. Subspecies formosa from Taiwan has been considered as doubtful and indistinguishable from the nominate population. The population in India suratensis (type locality Surat) and ceylonensis from Sri Lanka have fine rufous or buff spots on the back. There is a size reduction trend with specimens from southern India being smaller, and ceylonensis may merely be a part of this cline. The lesser and median wing-coverts are also spotted at the tip in buff. This spotting is lacking on populations further north and east of India, such as tigrina, which also differ greatly in vocalizations from the Indian forms. The population from Hainan Island is placed in hainana. Others like vacillans (=chinensis) and forresti (= tigrina) and edwardi (from Chabua = suratensis) have been considered invalid.<p>Five subspecies are recognised:<p>The subspecies S. c. suratensis and S. c. ceylonensis differ significantly from the other subspecies in both plumage and vocalization. This has led some ornithologists to treat S. c. suratensis as a separate species, the western spotted dove.

Répartition et habitat
The spotted dove in its native range in Asia is found across a range of habitats including woodland, scrub, farmland and habitation. In India it tends to be found in the moister regions, with the laughing dove (S. senegalensis) appearing more frequently in drier areas. These doves are mostly found on the ground where they forage for seeds and grain or on low vegetation.<p>The species has become established in many areas outside its native range. These areas include Hawaii, southern California, Mauritius, Australia and New Zealand.<p>In Australia they were introduced into Melbourne in the 1860s and have since spread but there is insufficient evidence that they compete with native doves. They are now found in streets, parks, gardens, agricultural areas, and tropical scrubs in diverse locations throughout eastern Australia and around the cities and major towns across southern Australia. The original populations appear to be S. c. chinensis and S. c. tigrina in varying proportions.

Martinet épineux
Hirundapus caudacutus
Un martinet d'apparence puissante avec de longues ailes en forme de sabre et un corps en forme de balle. Le seul martinet de son aire de répartition à combiner une gorge d'un blanc pur et un dos gris pâle uni. À courte distance, le front blanc fin et la légère teinte bleuâtre sur le dos sont également visibles. Vole plus haut que la plupart des autres martinets pendant la migration, souvent en cercle au-dessus des sommets et des vallées avec des "bouillons" d'oiseaux de proie migrateurs. Moins erratique et moins semblable à une chauve-souris en vol que les autres martinets. Le cri est un gazouillis strident et aigu.
Myrmidon de Cherrie
Myrmotherula cherriei
Myrmothère fortement strié. Les mâles sont noirs et blancs, tandis que les femelles sont chamois avec des stries noires. On le trouve dans les forêts saisonnièrement inondées avec des arbres courts, les savanes boisées sur sables blancs et les zones broussailleuses près de l'eau. Il se nourrit généralement dans le sous-bois et accompagne souvent les troupes mixtes d'espèces. Le chant est un trille ascendant. Difficile à distinguer des autres myrmothères striés de noir et blanc, mais cherchez le bec inférieur noir (pas gris) et les stries plus épaisses, en plus des différences dans le chant.
Bengali rouge
Amandava amandava
Remarquablement joli petit fringillidé. Les mâles sont majoritairement rouges et couverts de taches blanches, avec des ailes et une queue sombres. Les femelles sont grises avec un croupion roux. Les deux sexes ont un bec rouge. Il émet un chant très mélodieux et un cri aigu « teeï ». On le trouve dans les zones herbeuses proches de l'eau et souvent près des habitations humaines, en particulier dans les rizières inondées.
