Indian Courser
Cursorius coromandelicus
Elegant and stately large plover-like bird. Note typically erect posture, strong black-and-white brow pattern, orange-suffused crown and chest, and slightly downcurved dark bill. Cream-colored Courser is much paler and more uniformly colored. Indian Courser inhabits dry open spaces, including rocky plains and arid areas with scattered scrubs. Gathers in small flocks outside of the breeding season.
识别特征
This courser is widespread in South Asia and overlaps with some other species such as the similar looking cream-colored courser. This species is however brighter coloured than the cream-coloured courser and has a broader black eye-stripe that begins at the base of the beak. The crown is chestnut and the breast is rufous. The nape has a dark black patch where the long longer feathers forming the white stripe meet. In flight, the rump appears white and the wing tip is not as contrastingly black as in the cream-coloured courser. The sexes are alike.<p>The long legs are whitish and as in other coursers have only three forward pointing toes.<p>The species is closely related to other coursers in the region and are considered to form a superspecies with Cursorius cursor, Cursorius rufus and Cursorius temminckii.
分类信息
The Indian courser was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the plovers in the genus Charadrius and coined the binomial name Charadrius coromandelicus. Gmelin based his description on the "Coromandel plover" that had been described in 1785 by the English ornithologist John Latham in his A General Synopsis of Birds. Latham in turn based his own description on a hand-coloured print that accompanied Comte de Buffon's Histoire Naturelle des Oiseaux . The Indian courser is now placed in the genus Cursorius that was introduced by Latham in 1790. The genus name is from Latin cursor meaning "runner", from currere, "to run". The specific epithet is from the Coromandel Coast of India, the type locality. The species is monotypic: no subspecies are recognised.

分布与栖息地
This species occurs in dry stony, scrubby or rocky country but rarely on sandy terrain from the Indus valley east short of Bangladesh and south to the tip of Peninsular India. It sometimes occurs in the dry zone of northern Sri Lanka. The wet forest zones are avoided. In southern India, the drier zone on the east coast, the Coromandel region, where it is not uncommon gives it the species name. It is also found patchily distributed in other parts of the peninsula. Other areas where they are commonly seen include the Deccan plateau and the arid regions of northwestern India in Rajasthan and Gujarat. It is resident in some areas but makes local movements.

Hyacinth Macaw
Anodorhynchus hyacinthinus
Unmistakable huge macaw with cobalt blue plumage contrasting with a yellow eyering and bill base. Found at forest borders, in open woodland, and in savanna with palm trees, where mostly seen in pairs but also in small flocks. Feeds on palm fruits on the ground or in trees. Gives a series of loud croaking 'kraaa' notes.
Black Hawk-Eagle
Spizaetus tyrannus
Uncommon, spectacular, crested eagle of lowland tropical forest. Most frequently seen soaring in mid-late morning; rarely seen perched. Gives loud, far-carrying whistles while flying, which often indicate its presence. Adult is black overall with bold white checkering under the wings and bold white bands on the tail. Immatures, although rarely seen, are browner with a white throat and crown. The short bushy crest is usually apparent only on perched birds and is not seen in flight.
Rusty-margined Flycatcher
Myiozetetes cayanensis
One of several medium-sized, kiskadee-like flycatchers that are bright yellow below, with bold black-and-white head pattern. Rusty-margined is one of the smaller ones, with a smaller bill than Great Kiskadee. Most similar to Social and White-ringed Flycatchers; look for combination of black cheek (not gray) and especially obvious rufous in the wings. Shorter bill than White-ringed. Voice is helpful: listen for lazy-sounding, slightly burry “wheeer” call. Found in a variety of open wooded habitats such as forest edge and second growth, often around water.
