Bird Species Decline Concerns at Coimbatore's Periyakulam Lake
Imagine a lake that birds love to visit, like a vacation spot.
Now, imagine that the lake is changing.
People built new things like an amphitheater and food places.
Because of these changes, some birds are not visiting the lake as often.
The lake used to dry up in the summer, making a good spot for some birds to find food.
Now, because the lake has water all year, the birds don't have as much to eat.
Bird watchers have noticed fewer different types of birds coming to the lake.
Birdwatchers report a decline in bird species at Periyakulam Lake in Coimbatore.
Commercial infrastructure and increased human activity are cited as primary factors.
The number of observed species has decreased from 120+ to 82 in recent years.
Activities like amphitheater events, boating, and lighting disturb birds.
Changes to the lake's seasonal rhythm, including year-round water retention, affect bird habitats.
