Birds this season prefer security over the availability of water

Chennai:

The migratory bird’s show of intelligence this season has thrilled foresters and bird watchers this season and they say waterfowl seem to have chosen safety as their first preference over water availability.

Although large lakes and massive reservoirs are teeming with water exceeding storage levels at bird sanctuaries, the majority of migratory birds have congregated more in protected bird sanctuaries, ignoring other catchment areas. of water.

Thanks to good rains, the birds have abandoned their temporary locations this year, preferring to stay in less crowded and undisturbed areas, TN foresters said as they prepared for the annual synchronized bird count scheduled for next month.

“When there is sporadic rains across the state, bird migration is decentralized or dispersed. This year, several bodies of water are teeming with abundant fish, but more birds are coming to protected sites, ”said KVRK Thirunaranan, founder of The Nature Trust.

The general perception among birders is that more water means more bird arrivals, but this calculation is often wrong. Although lakes and reservoirs are overflowing this season, birds have mostly chosen safe, undisturbed habitats protected as bird sanctuaries.

For example, birds like the pelican regularly visit the Maruvathur and Maduranthagam reservoirs when Vedanthangal is scarce, but now all the reservoirs have abundant water and most of the birds have chosen Vedanthangal, suggesting that the sanctuary is theirs. first choice.

Although bird sanctuaries have less water than lakes and reservoirs located inside cities and rural areas, birds continue to choose their safety by avoiding sandwiched bodies of water first. in concrete jungles, ”Thirunaranan explained.

“Migratory birds practice adaptations and observing them in lakes and reservoirs outside protected forests is something common, but their general preference will be a natural eco-place. It is only when the bird sanctuaries are dry that the birds explore the man-made reservoirs and the lower lakes, ”said anti-poaching observer and bird tracker Raghavan from Udayamarthandapuram Bird Sanctuary.
