Animal populations, particularly certain vertebrates, do not have to be wounded to be harmed by humans. Many species do not thrive when in proximity to humans. Members of these sensitive species may stop taking adequate care of themselves. Food acquisition may diminish creating starvation. Short of starvation, inadequate food may result in systemic weakness and subsequently greater opportunity for infection or predation. Estrus, or "heat" may not occur leading to a drop in reproduction. Even with successful impregnation, stressed animals are more likely to experience gestational failure, or miscarriages. For instance, encounters with humans, even when benign, lead to reduced birth rates among leopards. Even birds, which are oviparous or egg-layers, produce fewer live young. Encounters with humans are associated with egg shell fragility in many predator birds.
