다도해해상국립공원 흑산도에서의 제비류 봄철 도래일 비교

Comparison of spring arrival dates for swallows in Heuksan-do, Dadohaehaesang National Park: Focusing on Barn Swallows and Red-rumped Swallows

다도해해상국립공원 흑산도에서의 제비과 도래 현황을 파악하기 위해 2007년부터 2021년까지 실시된 진리, 배낭기미, 예리초지의 정기모니터링 데이터를 기초로 분석하였다. 그 결과, 제비의 FAD는 평균 76.00일(±6.73일)이었으며, MAD는 평균 115.67일(±4.76일)로 나타났다. 제비는 3월 평균기온이 높아질수록 FAD가 빨라지는 경향을 보였으나 유의한 차이는 없는 것으로 나타났으며, MAD 역시 4월 평균 기온이 높아질수록 빨라졌으나 유의한 수준은 아니었다. 귀제비의 FAD는 평균 97.07일(±9.01일)이었으며, MAD는 평균 134.47일(±9.05일)로 나타났다. 귀제비는 4월 평균기온이 높아질수록 FAD가 빨라지는 경향을 보였으나 유의한 차이는 없는 것으로 나타났으며, MAD 역시 5월 평균기온이 높아질수록 빨리 도래하는 것으로 나타났으나 유의한 수준은 아니었다. 제비와 귀제비의 FAD는 평균 약 21일의 차이가 있는 것으로 나타났고, 두 종간의 MAD는 평균 약 19일의 차이가 있는 것으로 나타났다.

In order to understand the migration status of Family Hirundinidae in Heuksan-do(Island), Dadohaehaesang National Park, we analyzed daily count record from 2007 to 2022 at three study sites, Jin-ri, Baenanggimi and Ye-ri. As a result, the average FAD of Barn Swallows was 76.00 days (±6.73 days), and the average MAD was 115.67 days (±4.76 days). Barn Swallows showed a tendency for FAD to become faster as the March average temperature increased, but there was no significant difference. MAD became faster as the April average temperature increased, but it was not significant. The average FAD of Red-rumped Swallows was 97.07 days (±9.01 days), and the average MAD was 134.47 days (±9.05 days). The Red-rumped Swallows's FAD tended to arrive earlier as the April average temperature increased, but there was no significant difference. MAD also appeared to arrive earlier as the May average temperature increased, but it was not significant. The FAD of Barn Swallows and Red-rumped Swallows was found to have an average difference of about 21 days, and the MAD between the two species was found to have an average difference of about 19 days.
