Estimate. 30 birds munching on rice fields (some seen, others hid or went down), 10 each of 2 mahogany trees, another 5 birds on ipil tree. Around only 5 were adults. Most are juvenile and have almost pale plumage, no white cheeks or black. Bird Call - I recorded two kinds. First is the usual musical chirp. Second file is from one bird with rather raspy sound from juvenile bird.
