Barn Swallow (Hirundo rustica) Breeding Ground Temperature and Relative Humidity data in Sejong City and Seocheon County

Abstract

This study was conducted on the barn swallows that share habitats with humans, and the effect of changes in temperature and relative humidity, an important environmental factor for bird breeding, on swallow breeding was examined in Sejong City and Seocheon County. Barn swallows in both regions arrived from the end of April to the middle of June, and there was no big difference between the regions. In the average, maximum, and minimum temperatures at the time of arrival, there were no significant differences between the regions. The incubation period was confirmed twice. From 1 May to 20 May, the first incubation period the average temperature in the two regions was 17.3 to 18 ℃, and both the maximum and minimum temperatures were similar. The average temperature was 20.0 ℃ in Seocheon, 22.8 ℃ in Sejong, the maximum temperature was 26.9 ℃, and minimum temperature was 16.7 ℃. The brooding period in the two regions was 23.6~30.7 days on average, which was 7.1 days longer in Seocheon, and the average temperature, maximum temperature, and minimum temperature were similar.
