I went to Samarinda, East Kalimantan last week to give a talk on ecosystem service. It was a surprise that I met one of my bird ‘guru’ Bas van Balen at the Soekarno Hatta International Airport. It was what I called coincidence. The last time I went to East Kalimantan during 1998 was with him. We were conducting bird survey in a forest concession in Malinau, East Kalimantan.
