According to overseas research, birds of prey are highly territorial animals. The essential survival resources that their territories provide are food, nesting sites, and space to seek a mate. To win and defend a territory they are willing to pay any price, and even to fight to the death. But this kind of piecemeal tree felling causes fragmentation of their habitat, and is inevitably a threat to their survival.
根據國外研究，猛禽是領域性很強的物種，由於領域內的資源是覓食、築巢、求偶等生存所需，為了鞏固地盤，牠們甘願付出極大的代價，甚至奮戰到犧牲生命；像這類局部砍伐森林使棲地破碎化的現象，勢必危及牠們的生存。
