INTRODUCTION
Wetlands are defined as lands transitional
between terrestrial and aquatic eco-systems where the
water table is usually at or near the surface or the land is
covered by shallow water (Mitsch & Gosselink 1986).
The various reservoirs, shallow ponds and numerous
tanks support wetland biodiversity and add to the
country’s wetland wealth. It is estimated that freshwater
wetlands alone support 10 percent of the known range of
biodiversity in India (Deepa & Ramachandra 1999)
including 2400 birds species and sub species of birds.
Wetlands in India occupy 58.1 million hectares,
including areas under wet paddy cultivation
(Prasad et al., 2002)
Wetlands and waterbirds are inseparable
elements and support a rich array of waterbird
communities (Grimmett and Inskipp, 2007). Waterbirds
are an important component of most of the wetland
ecosystem as they occupy several trophic levels in the
food web of wetland nutrient cycles. Activities of
waterbirds are considered as indicator of quality of the
wetland ecosystem and form the terminal links in many
aquatic food chains, and as a result they reflect changes
originating in several different ecosystem components
(Custer and Osborne, 1977). Parish and Prentice (1989),
suggested various direct and indirect factors that causes
deterioration of wetlands all over the world. Factors that
cause wetland deterioration like vegetation changes,
deterioration of water quality, siltation, cattle grazing and
poaching were recorded in India by Vijayan (1986),
Anjaneyulu (1991), Sampath (1993) and Trisal (l993).
No in-depth study of ecology of wetlands as
birds habitat has been conducted in Madhya Pradesh.
Some sporadic references are available that too limited
to check listing of birds. Wetland ecology has been
studied in isolation lacking avian ecology. Barna wetland
of Madhya Pradesh is an identified wetland under
National Wetland Conservation Programme by Ministry
of Environment and Forests (Govt. of India). No detailed
study has been conducted on the water birds of the Barna
reservoir, but a preliminary survey in the winter of
2001- 2002 revealed a huge congregation of more than
20,000 birds on the main water body
(Islam & Rahmani, 2004). This site has not been covered
during the Asian Waterfowl Census, and needs regular
monitoring of water birds.
MATERIALS AND METHODS
Barna is one of the major irrigation projects of
Madhya Pradesh constructed by damming river Barna in
Raisen district near Bari village. This is located about
100 kms from Bhopal. Narmada basin is located at the
latitude 22°50’ 13.5” N and longitude 77°50’ 78.10” E.
This reservoir is an important source of fish production
in the area. Regular fish stoking is done in this reservoir
every year. The water of the reservoir is mainly used for
the fisheries and irrigation purpose. The reservoir
supports a rich biodiversity and provide habitat for
wildlife including migratory birds. A major part of the
reservoir basin falls under Singhori Wild Life Sanctuary.
Wetland habitats:
Study of avifaunal diversity of Barna wetland
was conducted between March, 2009 and February,
2011. Seasonal observations were made during the study
but they were clubbed into four observations for further
analysis. Birds were observed within the transect of
300m. Nikon Binoculars of 10×50 were used for
observations. The field book of Ali and Ripley (1986),
Ali (1996) were used to identify bird species. The
checklist was prepared using the standardized common
and scientific names of the birds of the Indian
subcontinent by Manakkadan and Pittie (2001).
Data analysis:
The statistical analysis was carried out using
software Paleontological Statics (PAST) version 2.04
(Hammer et al., 2001) to find out the significance of
spatial variation on biological parameters. Margalef’s
species richness (d), Shannon-Wiener diversity (H’) and
Balapure et al., 2012
461 Journal of Research in Biology (2012) 2(5): 460-468
Simpsons index (D) was calculated. Jaccard’s similarity
cluster was constructed based on bird species richness.
RESULTS AND DISCUSSION:
In the present study 63 bird species were
recorded from Barna reservoir belonging to 12 families
and seven orders (Table: 1). Das and Saikia 2011
recorded 39 species of water birds from 16 different
families from Deepor beel (Ramsar site) of Assam.
Family Anatidae was found to be the most dominant
family represented by 16 species followed by Ardeidae
with nine species and Charadriidae with eight species
(Fig:1). Family Recurvirostridae had only one species
Himantopus himantopus commonly known as Black
winged stilt. Rathore and Sharma (1999) also reported
Anatidae to be dominating family with 11 species in
Sarsai Nawar in UP. Surana (2007) recorded Anatidae to
be most dominant family with 11 species, Ardeidae with
nine species and Charadriidae with eight species in
Chimdi lake of Nepal. Tak et al., (2010) reported 31
water birds from Hathnikund wetland of Haryana with
maximum richness of Anatidae (35%) followed by
Ardeidae (19.6%). Rajashekara and Venkatesha (2011)
recorded Ardeidae to be the most dominating family
having nine species followed by Anatidae family having
five species from Bangalore lake.
Site-1, Site-4 and Site-7 harbored maximum bird
species richness compared to the other sites. The

Map of Barna reservoir in Narmada basin of central India were as study sites are
located zone wise
maximum diversity of water birds was noted at Site-4 as
47 species followed by Site-7 having 45 bird species,
Site-1 with 31 species (Fig:2). These sites were
characterized as shallower zones of the reservoir.
Minimum water bird assemblage was noted at Site-8,
Site-9 and Site-2. Family Anatidae, Phalacrocoracidae,
Rallidae and Alcedinidae were the abundant families of
Barna reservoir which were observed at all the sites
comprised of both shallower zone as well as deeper zone.
Family Ardeidae, Ciconiidae, Threskiornithidae,
Gruidae, Recurvirostridae, Charadriidae and Laridae
were restricted only in shallower zone of the reservoir.
Kurup (1991) attributed it to the larger mudflat areas
which attract shorebirds in large numbers. Cormorants
were noted both in shallow and deeper zone of the
reservoir. Waders were restricted to only shallow waters
having a depth of 2 mt. Deep water has been reported to
reduce the availability and accessibility of invertebrates
to feeding waders (Murkin and Kadlec, 1986).
Murkin et al., (1997) found that diving ducks as a group
selected habitat that consisted of deeper water and less
vegetation.
There was a temporal variation in bird diversity
(Fig:3). The maximum diversity of birds was noted in
winter season. Similar observation was noted by
Rajashekara and Venkatesha (2011) in 15 major lakes of
Bangalore during 2008. Chinchkhede and Kedar (2012)
reported 76 species belonging to 15 orders in and around
Koradi lake of Nagpur among which 54 species were
recorded as resident; 09 species as seasonal local migrant
and 13 species as winter migrant. There was a gradual
decline in species richness in the reservoir as the weather
condition changes from colder to warmer. A sharp
decline was recorded during summer 35 species of water
birds in the reservoir belonging to 12 families and 7
orders. With the onset of monsoon in June and July, the
field conditions are unsuitable for birds and the bird
occurrence was significantly low in all the study areas.
The diversity of birds vary according to the weather
conditions like rainfall, temperature, relative humidity
and precipitation changes have a profound effect on
water level, cover ratio and the quality of the habitat for
the water birds (Rao et al., 1997). Anatidae family which
was the most dominant family during winter period was
represented by sixteen species. This indicates that most
of the wintering water birds belong to Anatidae family.
Vyas et al., (2010) observed that Anatidae was the most
dominating family in Bhoj wetland. The second most
dominating family was Charadriidae represented by 10
species followed by Ardeidae represented by nine
species. Vijayan (1988) while working on Bharatpur
wetland also recorded similar observations. Members of
Anatidae family were found to dominate among the
winter migratory birds. Coot was the only dominant
migratory bird belonging to family Rallidae which could
not be recorded after Monsoon season in Barna reservoir.

Family Ardeidae comprised of Egrets and herons showed
an increasing population trend from the beginning of the
summer season. Vijayan (1987, 1988) recorded increase
in egret’s population during monsoon period due to their
breeding season.
The various diversity indices for water birds are
shown in Figure 4. The higher value for Shannon’s index
was observed at Site-4 (2.554) followed by Site-5 (2.4).
Simpson’s diversity index was highest at Site-6 followed
by Site-5 and Site-4. Species richness was highest at
Site-4 (6.14), followed by Site-7 (5.87) and Site-1 5.05).
Lowest species richness was recorded at Site-3, Site-6
and Site-9 having a depth of 4-6 mt.
The dendogram constructed showed the
similarity of the sites according to the species richness of
the water birds present at nine sites of Barna reservoir
(Fig: 5). Two main clusters were formed; first cluster
was formed with Site-1, Site-4 and Site-7. Among the
first cluster Site-4 and Site-7 forms a subgroup. These
two sites exhibit maximum species diversity as compared
