Portlandさんのインスタグラム写真 - (PortlandInstagram)「The annual return of the swifts is here! Witness the mesmerizing spectacle as thousands of Vaux’s swifts gracefully traverse the city during their migration from Canada to Central and South America. Chapman Elementary School in NW Portland is one of their preferred evening resting spots. To catch this incredible show, make sure to arrive at least thirty minutes before sunset. Don’t forget your binoculars, snacks, jackets, and a comfortable seat, and get ready for one of the city’s most captivating free events. 📷: Captured by @n1ck_on」9月20日 7時54分
