Biological Science and General Biology
While the images of swallows that appear close to people's homes when spring comes, beneficial birds that catch insects that eat agricultural products, and lucky birds that bring good fortune from raising children in eaves have changed with the times, they have been loved as the most familiar migratory birds that can be seen all over the country since ancient times. In addition to beautiful and dynamic visuals that capture various moments of swallows that are difficult to see with the naked eye and basic information on their ecology, there is also a special contribution by Mr. Katsu Hasegawa, a researcher who received the Japanese Ecology Society Suzuki Award and the Japanese Ornithology Society Kuroda Award for a research paper on swallows, and published articles such as the Secret of 『 Swallows 』 『 Swallows 』. In Japan, we will publish special articles that touch unknown aspects of swallows, such as the latest research situation, with a focus on "migration," which is a major feature of swallows that are summer birds. This book provides an opportunity to think anew about the importance and urgency of environmental conservation through the ecology of swallows.
