Checklist of land birds in Tenkasi and Ambasamudram Taluk, Tirunelveli
District: at the Foot Hills of Southern Western Ghats
Keywords: Land birds, ambasamudram, diversity.
ABSTRACT:
Birds present everywhere and are important ecological indicators. The study area Tenkasi (8.97°N 77.3°E) and Ambasumudram (8.7°N 77.47°E) region of Tirunelveli district, Tamilnadu state is at the foothills of Southern Western Ghats. Studies on distribution of birds in this part have been recorded from the yester years but due to various reasons it had been confine towards aquatic ecosystem. To fulfill this lacuna, present study was carried out. A total of 100 species of land birds were documented that belongs to 36 orders and 48 families. Study on nesting pattern, breeding pattern was also carried out. 30% of the birds had their breeding periods during rainy season and 50% of the birds had their breeding periods during harvesting time. Insectivores breeds during rainy season and granivores breeds during harvest season which supports ‘food availability-breeding time’ hypothesis.

Original Research
INTRODUCTION
Diversity studies have assumed a greater
urgency, partially as a result of incorporating habitat and
demographic information towards conservation. Birds
use diverse habitat and select their own habitat for
successful living. Out of more than 9,000 bird species of
the world, Indian subcontinent contains 1,300 species or
over 13% of the world’s bird species (Grimmet et al.,
1999). The study area Tenkasi and Ambasamudram
region of Tirunelveli district, Tamilnadu state is at the
foothill of Southern Western Ghats. This area has part of
Kalakad Mundunthurai Tiger Reserve (KMTR) and
Courtallam hills, got a rich amount of flora and fauna
and a good vegetation that give food and nest resources
for birds. Nearly 160 species of birds were observed to
present in KMTR (Joshua and Johnsingh, 1988). An
annotated check list of the birds of Tamilnadu is not
available, but more than 450 species are likely to occur
(Rathinam, 2002). Studies on distribution of birds in this
part have been recorded from early 1945 (Webb-Pelope,
1945), but the studies had limited towards wet-land
birds. It is mainly due to the climatic condition prevails
in this area. This region enjoys both the north east and
south west monsoon, with good wetland ecosystem that
provides habitat for aquatic birds. Koonthankulam bird
sanctuary is present in this region that inhabits more than
100 species of wetland birds. Hence most of the studies
on birds (Johnson,1971; Wilkinson, 1961;
Subramaninan, 2003; Johnsingh, 2001) were restricted
towards wetland birds and their conservation. As birds
are observed to be an ideal bioindicator and a useful tool
for studying a variety of environmental problems, the
habitat ecology of bird community should be evaluated
for their conservation (Kattan and Franco, 2004).
The Indian bird population has been declining due to
habitat loss, fragmentation, anthropogenic disturbances
that necessitates documentation, monitoring and
conservation.
In order to bring forth the avian diversity in this
area, an extensive survey was made to document the land
bird distribution with a note on their habitat and breeding
in Ambasumudram and Tenkasi Taluk of Southern
Tamilnadu.
MATERIALS AND METHODS
Study Area
Tenkasi (8.97°N 77.3°E; Elevation 554 feet) and
Ambasumuram (8.7°N 77.47°E; Elevation 229 feet)
taluk are regions of Tirunelveli district of Tamilnadu
(map) described as a microcosm of the state, owing to its
mosaic and diverse geographical and physical features
such as lofty mountains and low plains, thorn scrub
jungles, rivers and cascades, thick inland forest, sandy
soils and fertile alluvium, a variety of flora, fauna, and
protected wild life. The mean daily maximum
temperature is 32.1ºC. The weather is quite hot in
May and June and the maximum temperature some
times reaches 43ºC. This region enjoys winter
(December to March), Summer (April-June), Southwest
monsoon (June to September and North east monsoon
(October to November). The month of November is
generally with maximum rainfall. The average rainfall in
the district is 814.8 mm per annum.

Map: Study Area
Survey
This study on survey of land bird was conducted
from January 2012 to December 2012 for a period of one
year. Weekly field observations were made throughout
the study period, a total of 52 observations were done
during the study and birds in the study area
were documented. Survey was done in the nesting sites,
and information were gathered from local peoples and
villagers. With high precise birds were monitored during
morning (06 00 to 10 00 hrs) and evening
(15 00 to 18 30 hrs). Binoculars and monoculars were
used for observation. Nest sites were surveyed there by
getting information from local villagers. Birds were
identified using key reference books of birds of India
(Salim Ali, 2002) and Tamilnadu (Rathinam, 2002).
Diveristy Indices
Species richness was calculated by using
Margalef’s index and species dominance was calculated
by using Berger-Parker index. They were calculated by
using the formulae given below,
Margalef’s index
Species richness measures provide an instantly
comprehensible expression of diversity. It is calculated
using the formula,
Dmg = (S – 1)/ In N
Where,
S = Number of species present in each taluk
N = Number of individuals
Berger-Parker diversity index
Berger-Parker index is employed to determine
whether there is any change in the dominance of species
in each taluk. It expresses the proportional importance to
the most abundant species. The formula for calculating
the Berger-Parker index is
d = N max/N
Where,
N = the total number of individuals
Nmax = Number of individuals in the most abundant
species.
RESULT AND DISCUSION
A total of 100 species of birds that belongs to
16 orders and 36 families were recorded during the
study, of which order Passeriformes was observed to
have 19 families with 48 species (Table 1). Family
Sylviinae of order Passeriformes have a maximum
number of 8 species of total 100 species observed.
Passeriformies are group of birds that inhabit in a
vegetative rich area, that provide nesting and feeding
areas (Balachandran et al., 2005). Study area was
observed to provide a good resource for the bird
community. Of the 100 species observed, 75 were
observed to be residents and 16 were observed to
migrants, and 9 were both resident and migrant. Migrants
were observed to be from the western ghats region.
Study on species richness revealed that
Passeriformes shows a higher species richness.
Passer domesticus (Dmg: 1.598) Pirnia socialis
(Dmg: 1.497), Acrocephalus agricola (Dmg: 1.401),
Orthotomus subtorius (Dmg: 1.401), Corvus splendens
(Dmg: 1.400), Dendrocitta vagabunda (Dmg: 1.399),
Corvus macrorhynchos (Dmg: 1.387), Ardeola grayii
(Dmg: 1.350), Egretta grazetta (Dmg: 1.351),
Cosmerodius albus (Dmg: 1.320) were observed to have
a higher species richness. Species richness depends on
the habitat, climatic condition, food resource and
evolutionary history of the area (Jayson, 1994). On
estimating the dominance of species Corvus splendons
(d=0.393), Acridotherse tristis (d=0.390) had a greater
dominance. Dominance and richness of the species
depends mostly on the resource availability (Recher and
Davis, 2002).
Considering the feeding habit of bats 37 were
insectivorous, 22 were omnivores, 13 were granivore,
4 were piscivores, 4 were frugivores, 7 were carnivores,
3 were predators, 1 was nectarivore, 3 were insectivore
and piscivore, 2 were insectivore and frugivore, 1 was
carnivore and frugivore, 1 was predator and insectivore,
and 2 were insectivore and nectarivore. Insectivore and

granivore was observed to be greater in number in this
area due to the availability of food resources.
Study on nesting pattern of birds showed that
they were found to have a various pattern of nest. Birds
build cup nest (25 species), hole nest (24 species),
platform nest (15 species), pendent nest (5 species), bell
shaped nest (3 species), ground nests (2 species) and
oyster shaped nest (1 species). Birds were observed to
use variety of materials for nest construction (Table 2).
Study on breeding period of avifauna in the study
area revealed that 28 bird species had their breeding
period during June to November, 24 birds had their
breeding periods during December to March, and 17
birds had their breeding periods during April to June, and
6 birds had breeding period without any specificity
depending only on food and climatic conditions. 30% of
birds had their breeding periods during the rainy season
and 50% of birds had their breeding periods during

harvesting periods. Two harvesting season prevails in the
study area, first during the month of February to March
and second during the month of November. 24 birds had
their breeding during first harvesting season and another
24 during the second harvesting season. An interesting
fact was observed that the bird species which had their
breeding periods during rainy season were observed to
be insectivores and omnivores, and bird species that had
their breeding period during harvesting periods were
insectivores, granivores and omnivores. They had their
chance of survival to a maximum by adapting a
successful feeding strategy. During the rainy season
insect population will be more, hence insectivore breeds
during this time and they can feed their young one with
sumptuous amount of food, similarly birds that breed
during harvesting season were granivores, where they
got food at a greater amount to feed their young ones.
Food is believed to be one of the most critical resources
for the survival and reproduction of animals. A
wellknown theory in ecology known as the ‘food
availability-breeding time’, most birds breed at the time
when plenty of food is available for their chicks. Habitat
selection in birds is an account for their reproductive
success (Danchin et al., 1998).
CONCLUSION
Due to habitat loss, fragmentation and
urbanization a vast land area that provide roost resource
