Threatened
Birds of India |
Presenting a depressing
scenario of avian wealth, the IUCN Red List 2008 features India
prominently among the ten countries in the world having the largest
number of threatened species of birds. Brazil tops the list with 141
while India is ranked seventh with 78, reports the BirdLife
International, the Cambridge based global alliance of conservation
organisations and an authority for the IUCN Red List of Threatened
Species. Of the 78 threatened species in India, which includes migratory
species, 13 are categorized as Critically Endangered (facing an
extremely high risk of extinction in the wild), 10 as Endangered (facing
a very high risk of extinction in the wild) and the remaining as
Vulnerable (facing high risk of extinction in the wild). Two of the
species, Baer’s Pochard Aythya baeri and Spoon-billed Sandpiper
Eurynorhynchus pygmeus, have been uplisted, from Vulnerable to
Endangered and from Endangered to Critically Endangered respectively.
The decline of the Pochards’s population was
traced to wetland destruction while that of the charismatic Sandpiper’s
to habitat loss in its breeding, passage and wintering grounds and
effects of climate change. New research has shown the Yellow-breasted
Bunting Emberiza aureola to be rarer than it was believed.
Formerly classified, as Near Threatened it has been uplisted to
Vulnerable. Following the evaluation of its population size, the
Eurasian Curlew Numenius arquata was found to be rarer than
generally assumed, uplisting it to Near threatened. Likewise, following
the splitting of the newly recognized species, the populations of
Spelaeornis chocolatinus Long-tailed Wrenbabbler are small enough to
warrant uplisting it to Near Threatened status, from the previous status
of Least Concern. The decline of the populations of Blackish-breasted
Babbler Sphenocichla humei and Chevron-breasted Babbler
Sphenocichla roberti were traced to shifting cultivation, logging
and the reducing forest cover. Due to lack of reliable information on
its status, Andaman Crake Rallina canningi was formerly
classified as Data Deficient. New research has shown it to be somewhat
rare. Consequently, it is listed at Near Threatened. Elsewhere, the 2008
Red List makes grim reading with 1,226 species of bird in the world now
threatened and eight species newly uplisted to Critically Endangered,
the highest threat category. On the national front too, the picture is
grim with an addition of two species to the list as against the list of
2007 totaling to 76.

Description on the new IUCN Red List categories and criteria:
In late 1994, new criteria for the identification and categorisation of
threatened species were adopted by IUCN (IUCN SSC 1994). BirdLife
International played an integral role in the development of these
criteria over several years, and in the course of 1993–1994, used them
to determine the species in Birds to watch 2 (Collar et al.
1994). An outline of the criteria is given in the Introduction to
Birds to watch 2 along with a review of certain phenomena associated
with them. In the process of their official ratification, however, the
criteria were very slightly altered from the working set that BirdLife
had been using. We present below a brief account of these criteria, but
warn that anyone seriously planning to use them needs to refer to the
official booklet (IUCN SSC 1994) or to the following web site: http://iucn.org/themes/ssc/site
indx.htm The following categories and criteria are reproduced almost
wholly verbatim from IUCN SSC (1994). Several definitions needed
to interpret the criteria are appended.
