Another image of Seoul uploaded to Getty Images. I was walking up to an area with some old religious temple sites, that predate most of the religions that now are part of the local area on the northern side of Seoul. As the area is near the front line with North Korea you are allowed to take photos to the south and not to the north. This flock of birds was circling around. There were several different types of birds and they were quite noisy. I do not know why they were doing so. Maybe there was a thermal just there.
