Thanks. Do you have the Taisho reference for that Agama text? I'd like to look at it.
Some websites have the Hindi name of the openbilled stork as "Naththai Kuththi Narai" (but I can't make sense of this transliteration - I'm not convinced it's even Hindi). I've sent emails to Indian bird websites to try to get local names, and await replies. Hopefully I won't die before I get the information ;-)
