摘要

道路基础设施建设是人类活动导致生物多样性丧失最明显的原因之一。然而,它们为一些动物提供了一定的好处,比如狩猎的机会更低的能量成本和更早被车辆撞到的腐肉的消耗。迅猛龙发现道路是一个特别有利的环境,它们栖息在电线杆或架空的电缆上,等着攻击穿过道路的猎物。本文描述了有物证支持的第一次有记录的路边鹰(Rupornis magnirostris)对条纹蛇(Lygophis anomalus)的捕食,当时猛禽和蛇都是在蛇被抓住后立即被车辆击中的。这项研究有助于了解路边鹰的饮食,并阐明了这些人类基础设施给动物带来的问题。未来对猛禽作为狩猎地点的道路的研究可能有助于改善猛禽物种的保护计划。

Roadside hawk (Rupornis magnirostris) hit by an oncoming vehicle while capturing a striped snake (Lygophis anomalus)
Abstract One of the most apparent origins of biodiversity loss caused by humans is infrastructural development of roads. Yet they offer certain benefits for some animals, such as hunting opportunities with lower energy costs and consumption of carrion earlier hit by vehicles. Raptors find roads a particularly favorable environment, perching on poles or overhead cables and waiting to attack their prey as it crosses a road. This paper describes the first ever recorded predation by a roadside hawk (Rupornis magnirostris) of a striped snake (Lygophis anomalus) supportable by material evidence, when both the raptor and the snake were hit by a vehicle immediately after the snake was caught. The study contributes to knowledge about the roadside hawk’s diet and illuminates the problem these human infrastructures pose for animals. Future research on roads birds of prey use as hunting sites could contribute toward improvements in conservation programs for birds of prey species.
