While on a morning birdwatching trip to Ousteri Lake (South of Pondicherry) 18/02/2010 - about 8.00 am - I noticed a Pheasant Tailed Jacana having laid 3 eggs on a floating Thermocole debris!!. The debris in the form of a small (roughly 30 cm x 20 cm) though thick piece of thermocole packaging material was floating at a very slight angle and seemed anchored amongst surrounding lotus leaves.
The nest was an active one and the Jacana sat on the eggs soon after I identified the nest.
There are a few questions this throws up
1. Is this a freak phenomena or has it been reported from other parts
2. Eggs on white thermocole definitely make the nest very conspicous as opposed to the well camouflaged eggs laid on floating natural material. What impact does this have on the survival rates of the eggs
3. As an extension does this mean that floating platforms of this kind - better camouflaged, can be used to help in nesting of Jacanas
