Yangil High School Swallow Survey

We observed swallow nests in Yangpyeong Market and organized the camera recordings into a website built for close review.

Project background

Observing nests inside a living market.

This work is part of the 2026 Yangpyeong Swallow Survey organized by Yangpyeong Eco Action. A small group from Yangil High School joined after noticing that many swallows had nested throughout Yangpyeong Market.

With a shopkeeper's consent, an observation camera was installed at one store. Recording began in June 2026, and new footage continues to be added to the archive. Dr. Dami Jeong of the Gguruksae Research Institute also assisted with the project.

Location

Yangpyeong Market

The camera was installed at a market shop after receiving the shopkeeper's consent.

Period

2026—Ongoing

Observation began in June 2026, and recording continues.

Archive

A growing video record

New footage is published as it becomes available and organized by time, date, and daylight conditions.

Web production

Turning footage into a research tool.

The archive helps us find, replay, and compare relevant moments across long recordings.

Cloudflare Pages and R2

The React interface is deployed on Cloudflare Pages, while large MP4 files are delivered from Cloudflare R2. This was my first production use of R2.

Observation video player

The interface supports date, daylight, and filename filters; continuous playback; 10-second and frame stepping; speeds up to 16×; frame capture; and a fixed nest crop.

AI-assisted highlights

AI is used to identify candidate moments for review. Verified scenes are then added to the highlight timeline.

In-browser image processing

The browser handles the nest crop and enlargement with Canvas. High-quality interpolation, sharpening, contrast, and saturation adjustments run live.

What I learned

Using web technology for ecological observation.

Swallows nest very close to human activity. Field observation and recorded footage helped us document their behavior and examine how people and birds share space in a market environment.

The website makes long recordings searchable and allows the same moments to be compared repeatedly. It applies my web skills directly to the research process.

Possible next step

Following migration routes.

A follow-up study tracking swallow migration routes is being considered with teachers at Yangil High School and relevant experts. The current observation record will be used to define the method and scope of collaboration.
