Their sighting at Hope Island adds Andhra Pradesh to the list of important flamingo habitats in India.

Habitat Preference of Greater Flamingos

Greater Flamingos prefer:

• Shallow saline and brackish water bodies

• Lagoons

• Estuaries

• Salt pans

• Coastal wetlands

These habitats provide:

• Abundant algae

• Plankton

• Small crustaceans
  which form the core of their diet.

Why Are Flamingos Pink?

The iconic pink colour of Greater Flamingos comes from carotenoid pigments found in their food:

• Algae

• Plankton

• Small crustaceans

As they consume these organisms, pigments accumulate in their feathers, giving them their distinctive pink to reddish hue.

• Known for synchronized movements and group feeding

• Form monogamous pairs

• Nest in large breeding colonies

• Strong parental care

Their social structure helps in:

• Protection from predators

• Efficient foraging

• Successful breeding

Conservation Status

• IUCN Red List: Least Concern

Although their global population is stable, local threats remain significant.

Threats to Flamingos and Coastal Wetlands

Despite being listed as Least Concern, Greater Flamingos face several regional threats:

• Destruction of wetlands

• Coastal development projects

• Pollution and plastic waste

• Disturbance from tourism

• Climate change and sea-level rise

• Reduction in food availability due to water contamination

Protecting habitats like Coringa Wildlife Sanctuary is essential for their long-term survival.

Ecological Importance of Flamingos

Greater Flamingos play a key role in wetland ecosystems:

• Help in nutrient cycling

• Maintain balance in aquatic food chains

• Act as bio-indicators of ecosystem health

• Support eco-tourism and conservation awareness

Their presence reflects the quality of water and food availability in a region.

Significance of Their Arrival at Hope Island

The arrival of nearly 70 Greater Flamingos at Hope Island is significant because:

• It indicates a healthy coastal ecosystem

• Shows improvement in wetland conservation

• Enhances Coringa’s importance as a bird habitat

• Strengthens Andhra Pradesh’s position on India’s migratory bird map

• Promotes eco-tourism and biodiversity awareness

For students preparing for UPSC, State PSCs, and environmental studies, this event is highly relevant under:

• Biodiversity conservation

• Wetland ecosystems

• Mangrove forests

• Migratory birds in India

Conclusion

The sighting of Greater Flamingos at Hope Island in Coringa Wildlife Sanctuary is a powerful reminder of the importance of preserving India’s fragile coastal ecosystems. Coringa’s mangroves, estuaries, and sand-spit islands together create an ideal habitat for migratory birds and marine biodiversity. Protecting such regions is not just about saving wildlife; it is about ensuring ecological balance, disaster resilience, and sustainable development.
