초록

본 연구는 야생조류의 새벽 지저귐 시작시간에 영향을 미치는 환경요인과 종간 차이를 밝히는데 그 목적이 있다. 음성녹음은 봄철(2014년 4월~7월) 번식기 동안 일출 2시간 전에 시작하여 매일 2시간씩 실시하였다. 녹음된 소리는 분석 프로그램(Adobe Audition CC)을 이용하여 소노그램 패턴 확인을 통해 종을 구분하고 종별 지저귐 개시 시간을 분석하였다. 야생조류 지저귐 시작시간과 환경요인 및 종간차이 분석을 위해 한국 기상청으로부터 기상자료(일강수량, 율리안일, 일출시간, 월출시간, 온도, 여명시간)를 구하였다. 연구결과, 일강수량과 월출시간을 제외한 모든 환경요인이 야생조류의 지저귐 개시 시간과 상관관계가 있음을 확인하였다. 또한 야생조류 종간 지저귐 개시 시간에 차이가 있었다. 야생조류는 지저귐 개시 시간 차이에 따라 3개 그룹(일찍 일어나는 새, 중간에 일어나는 새, 늦게 일어나는 새)으로 구분되었다. 꿩과 노랑턱멧새는 일찍 일어나는 새 그룹에 속하였고, 딱따구리류는 늦게 일어나는 그룹에 속하였다. 본 연구는 한국의 야생조류를 대상으로 지저귐 개시 시간에 대한 우선순위를 밝힌 최초의 논문이라는 데서 의미가 있다. 그러나 왜 종별로 지저귐 개시 시간에 차이가 나는지에 대해서는 후속 연구가 필요하다.

This study aims to identify the difference in the starting time of the dawn chorus of different species of birds and related environmental conditions. For this study, the bird songs were recorded every 2 hours a day starting from 2 hours before sunrise for a whole spring season (from April to June, 2014) in Korea. The recorded sounds were analyzed to find the starting time of each species' song by sonogram pattern using a sound analyzing program (Adobe Audition CC). To analyze the relationship between the environmental conditions and the time of the birdsong of each species, we collected the data of environmental conditions: daily precipitation, Julian date, time of sunrise and moonrise, temperature data and twilight time from the Korea Meteorological Office. As a result of this study, it was found that there are several statistical correlation between the starting time of the birdsong and environmental conditions (every environmental condition except daily precipitation and time of moonrise). Also, the difference of the starting time among each species were identified. The species were divided into 3 groups (early, mid and late) by their wake-up time. Ring-necked pheasant and yellow-throated bunting were categorized as 'Early' group and all woodpeckers were categorized as'Late' group. This study is significant as it first presented a classification of wild birds in Korea by the starting time of their dawn chorus. However, further studies are required to identify why each species to do their dawn singing at different times.
