Abstract

Electrocution is one of the key components affecting the mortality of birds. Various electrocution-decreasing methods refer to two directions: safe perching with insulation versus perching restriction. In Yesan County, we have reintroduced 30 oriental storks (Ciconia boyciana) since 2015. Two female storks died due to electrocution while perching in a utility pole in 2016. To reduce such electrocution mortality in storks, a branch of Korea Electric Power Corporation partly installed insulators in 630 utility poles located in the major habitats of Yesan in 2016-2017. Simultaneously, we conducted an experiment to reduce the perching events using 8 captive storks and the two types of common utility poles along with/without the installation of bird-spikes and/or wires in Mar-Jun of 2017. Our results indicated the installation of additional wires alone exhibited a lack of reduction in perching, while those of bird-spikes or both significantly decreased their perching frequencies. Therefore, the present study highlights the installation of bird spikes on top of utility poles may elicit a better effect so that storks avoid perching in utility poles, presumably resulting in lowering potential electrocution in the wild.

감전사는 야생 조류의 사망에 영향을 끼치는 중요한 요인 중 하나이다. 예산군에서는 2015년부터 총 30마리의 황새(Ciconia boyciana)를 야생으로 복귀시켰지만 2마리가 전봇대에서 감전으로 사망하였다. 감전으로 인한 사망을 줄이기 위해서 사육 황새 8마리를 대상으로 전봇대를 횃대로 사용하는 것을 감소시키기 위한 실험을 수행하였다. 2017년 3월부터 5월까지 흔한 2가지 형태의 전봇대에 조류퇴치용 스파이크와 와이어를 조합하여 설치한 후 황새의 이용 현황을 확인하였다. 실험 결과 스파이크 또는 스파이크와 와이어를 조합한 전봇대에는 황새의 횃대 사용이 유의미하게 줄어든 것을 관찰할 수 있었다. 본 연구를 통해 전봇대 상부에 조류퇴치용 스파이크 설치가 황새의 전봇대 이용을 줄일 수 있다는 것을 확인할 수 있었다.
