On this excursion, Hwang Mei-hsiu and Lin Kuan-fu, both old hands in foraying, locate an average of five or six piles of feces of varying ages each day, not a bad result given the restrictions that terrain, vegetation density and weather place on two-legged humans.
以此行為例，黃美秀和林冠甫 2 位老手在森林間搜尋，平均每天找到新舊不等的排遺 5 ~ 6 坨，已算戰績不錯，畢竟只有兩隻腳的人類會受限於地形崎嶇、植被密度、氣候條件，而偵測犬則全無此類限制，凡是黑熊穿梭出沒之境，都逃不出牠的追獵。
