In 2012 and 2013, students participating in the Cornell Expeditions in Field Ornithology went to Tawau Hills Park in Sabah, Malaysia on the island of Borneo to study Suboscine birds: Pittas, Broadbills and Green Broadbills. The expedition was funded in part by Ivy Expedition Fund and led by Prof. David Winkler, in the Department of Ecology and Evolutionary Biology.
