Heard the unusual call of Serpent eagle from a distance. Spotted an adult bird, perched on the lateral branch of a mango tree. It was frequently giving a "Hrreeeee....." call, which was a reply for the similar call from another bird, which was somewhere in the vicinity (couldn't see it). The other bird was giving more than one type of calls, including the unusual one and the normal "Pheuu... pheu.. pheu..." song. Later they flew away to another area and continued to utter vocalisations. Vocalisations were recorded.
