The Kerala state has about 463 bird species within its political boundary.The woodpeckers, piculets, wrynecks, and sapsuckers are a family, Picidae, of near-passerine birds. Members of this family are found worldwide,a few species are known to live in treeless areas such as rocky hillsides and deserts.
There are about 200 species and about 30 genera in this family. Many species are threatened or endangered due to loss of habitat or habitat fragmentation. The smallest woodpecker is the Bar-breasted Piculet, at 7 g and 8 cm (3¼ inches). The largest woodpecker was the Imperial Woodpecker, at an average of 58 cm (23 inches) and probably over 600 g (1.3 lb). The Ivory-billed Woodpecker is (or was) slightly smaller at 50 cm (20 inches) and a weight of 500 g (1.1 lb). If both the Ivory-billed and Imperial Woodpeckers are indeed extinct, the largest extant woodpecker is the Great Slaty Woodpecker ofSoutheast Asia, at about 50 cm (20 inches) and 450 g (1 lb). A number of species exhibit sexual dimorphism in size, bill length and weight. In the piculets it is often the females that are larger, amongst the woodpeckers that show sexual dimorphism it is usually the males that are larger.
The Forest Department of Kerala has just completed the first-ever ornithological survey for the Malabar region recording 341 species of birds.
The survey is one of a kind notable for its sheer depth and span, more comprehensive than all such surveys undertaken so far in India. Hopefully, the five-member team including four eminent ornithologists commissioned by the Forest Department of Kerala, having completed such a through status report on the birds of Kerala, has established a new national benchmark for all such wildlife surveys in future.
The survey spans locations in North Kerala, which covers Palakkad, Malappuram, Kozhikode, Wayanad, Kannur and Kasargode districts. The area extends from the Ghats, through the midlands, to the seacoast, which lies north of Palakkad Gap.
The forest areas studied are the Silent Valley National Park, Mannarkad forest division, Nilambur North and South divisions, the Malabar Wildlife Sanctuary, the Wayanad Wildlife Sanctuary, Aralam Wildlife Sanctuary and their neighbouring areas as well as the Reserve Forests of Kasargode district and the wetlands of North Malabar.
2 of the 341 species surveyed belong to globally-threatened category as notified by IUCN. Alarmingly, of the 22 threatened species 17 are residents and, of which 9 are specifically endemic to Western Ghat. 15 species of birds are found to be abundant in the region, of which two are migrants, and one endemic. They include Yellow-browed Bulbul, Small Sunbird; Green Leaf-Warbler, Large–billed Leaf-Warbler and the three species of Bulbuls including the Black Bulbul.
The surveyors spent a year (from November 1 2010 to the middle of October 2011) during, which they had covered over 4000 km, trekking through treacherous forest areas enduring extreme weather conditions and threats from wild animals.
