Managing Avian Conservation,
Protection, and Diversity in
Indian Cities
Ramanath Jha
Birds provide multiple benefits to the world’s ecosystems. In recent
years, experts have raised the alarm about deteriorating bird
populations, with some species becoming extinct and others threatened
to dangerous levels. This decline in avian populations is primarily
attributed to urbanisation. Concerted efforts are required to conserve
birds and their habitats in cities. The Government of India, state
governments, urban local bodies, non-government organisations, bird
welfare organisations, and the urban community will all play a vital
role.

here are more than 11,000 species of birds globally,1 populating
every country across all regions, displaying behaviours shaped
by their unique ecological challenges, and equipped with the
ability to adapt.2 For example, while some species have evolved
to adapt to extreme climates, others can fly long distances to
more suitable climates.a,3 Bird species contribute to the preservation of rural
and urban ecosystems through pollination, seed dispersal, forest regeneration,
scavenging, and weed and pest control. Around 5 percent of the plants used
by humans for food and medicine are pollinated by birds.4 Bird droppings
also contribute to nutrient distribution. In this context, the role of sea birds
is especially crucial. These birds eat fish and other sea creatures on the high
seas and nest in large colonies on land. The excrement of the birds provides
concentrated nutrients to the soil at their coastal breeding grounds,5 enabling
plant and grass growth.
chain.8 The loss of bird species is likely to increase insect and rodent populations
and vector-borne diseases.9 For example, the population decline of vultures in
the mid-1990s in India10 led to a sudden increase in the population of stray
dogs, especially in cities.11,12
When avian species become extinct, their specific functions and benefits are
also removed. Bird diversity is therefore critical, especially since introduced
species often struggle to perform the critical roles of native species.13
There is a growing body of evidence that points to the positive impact of birds
on human mental health. A seminal study has found that birds provided
psychological, physiological, aesthetic, cultural, recreational, socio-economic,

and spiritual benefits.14 The study covered more than 100 scientific articles to
assess the relationship between birds and human health.15
Higher bird diversity is likely to have direct positive impacts on mental health
and create a more relaxing environment that enables mental restoration.16
Studies have suggested that bird species diversity in a locality boosts the mental
health of residents.17 The number of people hospitalised for mood and anxiety
disorders is also found to be reduced in areas with higher bird diversity.18
In India, birds have been part of the art,19 culture,20 and folklore of societies,21
with the swan and the owl, for instance, having symbolic value in traditions.22
The birds of India are widely documented in ancient Indian literature.23 More
recently, the Hindi film industry has explored the value of birds.24
Certain birds have also been domesticated and are kept as pets. Popular
species in India include non-Indian parakeets, cockatiels, canaries, macaws,
and lovebirds.25 However, the Wildlife Protection Act prevents the keeping
of several species as pets.26 The species that can be legally kept are cockatiels,
parakeet, lovebirds, zebra finches, doves, and hyacinth macaws.27 Nevertheless,
all Indian species are protected under law.

T
he State of the World’s Birds 2022 report recognises that birds are
“an excellent barometer for planetary health” and are valuable
biodiversity indicators whose health is indicative of the health of
the global ecosystem.28 However, according to the report, one
out of every eight bird species is threatened with extinction,
and the overall status of birds continues to deteriorate along with a decline
in their overall number.29 It is estimated that 2.9 billion birds have been lost
in North America since 1970 and 600 million in the European Union since
1980.30 Among the critical factors responsible for this decline are agricultural
expansion and intensification, unsustainable logging, overexploitation, and
climate change. Threats are also posed by bycatchb from fisheries and poorly
planned energy production.
United States, many raptor species experienced revival following the ban on
the insecticide DDT (dichloro-diphenyl-trichloroethane),33 and threatened
species grew in numbers following protection under the Endangered Species
Act.34 The State of the World’s Birds report urges governments to adopt the Global
World’’ s Birds
b Bycatch from fisheries refers to birds being caught on baited hooks and getting tangled in nets in the
process of unsustainable harvest of fish. Such unfriendly and careless seabird practices lead to the
death and mutilation of millions of sea birds.
c The Framework is designed to support the global response to the threat of climate change. It aims
to catalyse action by governments and civil society stakeholders at every level to halt and reverse
biodiversity loss.

T
he State of India’s Birds was compiled from the observations of
30,000 birdwatchers and 30 institutions across the country.36
Overall, 1,350 bird species have been recorded in India. Of
these, 942 bird species were studied. The report found that,

of the species studied, 142 were on the decline, with the great
Indian bustard, white-bellied heron, Bengal florican, and Finn’s weaver being
the most critically threatened species. On the other hand, 28 species populations
were found to be thriving, including the Indian peafowl, rock pigeon, Asian
koel, and house crow.37 In general, the study concluded that generalist speciesd
of birds had adapted to urban spaces, whereas survival and adaptability among
specialist species was more challenging, resulting in their decline.38 Other
research has indicated that omnivores39 have a better chance of survival in
cities, where food sources may not be diverse but are plentiful. Additionally,
bird species in cities are highly adaptable and learn to live alongside human

n India, urbanisation is named one of the primary factors for the decline
of birds.45 Increased construction activities have led to the destruction
of the natural habitats of birds, adversely affecting their species variety
and populations.46 Reduced canopy cover, decline in the variety of plant
species, and diminishing heterogeneity of vegetatione have adversely
impacted overall bird diversity.47 Additionally, pets such as cats and dogs prey
on birds and affect them by creating a landscape of fear.48 Studies in countries
outside India estimate bird loss in billions as a consequence of predatory pets.
However, the extent of the problem in India is uninvestigated.49 Urban noise is a
further deterrent to birds, forcing them to abandon previously suitable habitats.
Similarly, urban lights can disorient them, and glass facades of buildings are
Urbanisation and the
The report established that the most urbanised areas have the least number
of bird species, including the rare ones and those that are insectivorous.
Urbanisation leads to the homogenisationf of bird communities due to the
increased abundance of birds that are adept at exploiting ecological niches,
including the rock pigeon, common myna, and house crow.g,51
Impact on Birds
e Vegetation heterogeneity refers to variability in the structure and composition of plant communities
over space and time.
f Homogenisation of bird species refers to a process by which urban characteristics, such as limited
biodiversity and food variety, force many specialist bird species to lose out and many dominant bird
species such as House Crows and feral Rock pigeons to thrive, thereby spawning uniformity among
urban bird species. Specialist bird species are those that are highly adapted to specific eco-systems,
that are very sensitive to temperature and environmental changes, may eat merely one or two types of
food and require one specific species of tree for nesting. In their absence, they find it difficult to thrive.
g Despite the challenges, a number of bird species can still be spotted in Indian cities. These include
the black kite, rose-ringed parakeet, kingfisher, red-vented bulbul, green bee-eater, black drongo,
Asian koel, purple sunbird, greater coucal, Indian roller, and Indian robin. See: https://jeevoka.com/

n December 2019, the Ministry of Environment, Forest and Climate
Change, Government of India proposed a draft ‘Visionary Perspective
Plan (2020-20230)’ (VPP) for the conservation of avian diversity, their
ecosystems, habitats and landscapes in the country.52
The VPP highlights that India ranks among the top 10 countries in
bird diversity globally, with 1,317 species of birds, and is a mega-biodiversity
country, with many endemic species. India’s territory also includes regions
such as the Eastern Himalayas and the Western Ghats, which are categorised as
‘global biodiversity hotspots’ that are under severe threat and requiring urgent
conservation measures.53 India is also a signatory to several international
Current Approach on
The VPP also notes that the Indian Constitution stipulates that it is the duty
of every Indian citizen to protect the country’s natural environment, including
forests, lakes, rivers, and wildlife, and to have compassion for living creatures.56
The Constitution further exhorts the states to protect and improve the
environment and safeguard the forests and wildlife in their territory.57
The VPP builds on existing databases such as Asian Waterbird Census and
eBird to propose the generation and consolidation of baseline information
on birds and their populations in cities and towns in the country. It
recommends studying the impact of urbanisation on avian diversity, their
habitats, and behaviour, including their foraging and nesting ecology. The
8
VPP further urges the development of Best Practice Guidelines for integrating
environmental issues such as habitats for nature conservation into master plans
and development plans in cities and towns. Another objective is coordination
between Central and State government departments, urban development
agencies, relevant institutions, and other stakeholders to incorporate the Best
Practice Guidelines in urban policy and planning.59
thrust areas and an implementation schedule for each, categorised into long-
term, medium-term, and short-term applications. Conducting bird census in

citizen science initiatives are suggested strategies.60

A
conscious attempt needs to be made for the well-being of birds
in urban settlements. Along with the implementation of the
suggestions provided by the VPP, cities can follow a threefold
approach for bird rejuvenation and protection: (i) threat
reduction measures for birds; (ii) protection and creation of pro-
bird habitats; and (iii) promotion of popular participation in the multiplication

of bird-friendly neighbourhoods.
Urban local bodies (ULBs) play the most significant role in managing bird
populations. The plantation of trees and shrubs and other methods of greening
are necessary. Urban planners should safeguard natural habitats, including
terrestrial and wetland habitats, and maximise connectivity by promoting the
planting of native trees and shrubs in parks, gardens, and streets. Taller trees,
Avian Conservation
which are removed from the din, noise, and pollution, seem to provide greater
comfort to birds. Factors such as this should be considered by municipal tree
departments.
Trees play a vital role in wildlife conservation.61 They provide birds with nesting
sites and are a crucial source of food.62 Their branches and foliage also provide
shelter from predators and inclement weather. Consequently, trees help diversify
bird species and create corridors for bird migration.63 Birds, in turn, support
the health of trees by feasting on leaf-eating insects. Birds also eat and disperse
fruits and seeds, thereby allowing trees to multiply. Community engagement
programs can supplement municipal effort by mobilising volunteers to plant
and care for trees in cities.

can provide safe habitats for birds and strengthen the bond between humans
and nature while supporting diverse bird species.
A study conducted by the Singapore National Parks Board (NPB) found that
Imperatives in Cities for
urban green spaces with semi-natural vegetation are highly supportive of bird
diversity.66 The study also highlighted that regular-shaped urban green spaces
and ones with fewer edges are more conducive for bird diversity.67 For instance,
large and more complex green spaces contain more birds with specific food
and nesting requirements compared to small and manicured parks.68 A water
body within or around a green space also elevates bird diversity. Dead and
decaying trees provide multiple sources of food for insect-eating birds as well
Avian Conservation
and are ideal for cavity-nesting birds such as owls, parakeets, mynas, barbets,
and woodpeckers because the wood is easy to carve. Deadwood areas are also
preferred by birds for protection and nesting.
The use of glass and glass windows on the facades of buildings is proving to be
destructive to bird populations. Windows that reflect trees and the sky result
in birds flying into them, as birds cannot differentiate between reflections and
real vegetation.69,70 In other instances, a bird views its own reflection as a rival
and launches several attacks on a window pane.71 Therefore, a large number
of birds, especially migrating birds that generally fly during night, become
casualties as they collide with buildings. To address this challenge, cities can
reduce the amount of glass on buildings, put markings on glass that are visible
to birds, or stick non-reflective stickers on the glass surface to stop reflections.
Shutters and shades, for instance, can be used to hide glass so that birds are not
drawn to the light from windows.
While the use of glass facades in India is more common in the larger cities, the
trend is catching up in other cities as well and could become a huge problem
over time. Awareness with regard to the danger of glass facades to birds, as well
as their role in the additional generation of urban heat, need to be raised. Rules
should be framed to disincetivise the use of such facades.
11
City Regulations for the Protection of Birds
plans of cities and towns.72 For instance, many American and Canadian cities
have bird-safe building regulations in place. Building design regulations
mandate the glazing or treatment of glass on the first few storeys above ground
level.73 The regulations also dictate a minimum value of building facade or glass
percentage that would pass the bird-safe test.74 In New York City, for example,
Local Law 15 was introduced in 2020 which specifically deals with bird-friendly
building design, making it mandatory for new buildings to comply with bird-
Avian Conservation
Indian cities can look to these laws for lessons, and ensure that the
implementation gaps in those foreign cities are not repeated.
Community-Level Interventions
12
In India, the Bombay Natural History Society, BirdLife International, Royal
Society for Protection of Birds, Salim Ali Centre for Ornithology & History,
Indian Institute of Public Administration, Wildlife Institute of India, and other
non-government organisations have set up the Indian Bird Conservation
Network (IBCN).79 The IBCN aims to take steps for the conservation of
birds based on research. The network has state-level coordinators who collect
Imperatives in Cities for
regional and local information and feed these data and observations to the wider
network.80 The Bombay Natural History Society runs nation-wide projects for
data collection. The BirdLife International specifically deals with endangered
species or habitat-specific bird species to shortlist a minimum set of sites for
conservation. The IBCN also works in the areas of advocacy, education, and
scientific research.81
Avian Conservation
Birdwatching can aid urban health, urban ecology, and community involvement
in a positive urban activity. The use of technology has led to increased interest
in birdwatching.83 It is predicted that, aided by technology and tech diffusion,
birding could become a social media movement by 2025.84 Traditionally,
birdwatching requires a pair of binoculars, a notebook, a spotting scope with
a tripod, and a field guide. Technology is now providing new tools to make
birding richer and simpler, allowing each birder to access a large amount of
information and knowledge.85 Available technologies include bird-identification
apps, online resources, and social media platforms.86

T
he conservation of birds is imperative for the overall health
of ecosystems. Urbanisation is a critical threat factor in bird
populations, which makes it incumbent on city stakeholders
to engage in the conservation of birds and their habitats. This
attention needs to be especially focused on bird species that are
threatened with extinction and ones with dwindling populations. Accordingly,
there are three specific kinds of inputs required for bird conservation: more
research about birds in cities, targeted ULB action and regulation for birds,
and increased community participation for bird conservation.
Despite the high human and built density in Indian cities, it is possible to take
conscious steps to help birds, such as through birding, greening of available
open spaces, preserving water bodies, planting trees that bear flower and fruits,
installing birdhouses, providing drinking troughs, crafting nesting spaces, and
increasing roof gardens and plantations.
ULBs, while framing rules and regulations, could incentivise bird preservation
measures and encourage local communities to assist in bird preservation. The
task is intricate and cannot be accomplished without community support. It
would also be beneficial to recognise the services of the community, which can
incentivise them and encourage involvement.
There are gaps in the understanding of bird behaviour and the consequences
of human activity on their lives. To bridge these gaps and address challenges
in bird conservation, cities need to encourage related research projects and
