Document your backyard sightings and join a community of mariners tracking the species they love.
Explore. Species by species.
Raptors. Songbirds. Shorebirds. Waterfowl. Sea Log is built around the species guides that define marine observation.
Pick a habitat and build your sighting log one species at a time. Every sighting updates your progress. The birds you haven't spotted yet are still there waiting — and seeing the same species a year later with better optics tells a story no other platform tracks.
Track the field. Share the discovery.
When you start marine observation, you need somewhere that understands what you're building. Sea Log organizes your sightings around the field guides that matter to mariners — species profiles, habitat types, seasonal patterns, and more. Each photo lives inside your journal, not just a folder.
The satisfying part is watching your species count grow. Every bird you spot gets added to your list — and the ones you haven't sighted yet are still there, waiting. See the same species a year later with better binoculars, upload both photos, and you have a record of how far you've come.
Not just another photo album. A curated journal to work against and work towards. Mastering the backyard.
Every mariner was once someone who just looked up.
When you do take the plunge, the mariners in this community have been where you are — they know which binoculars to start with, which habitats are most rewarding, and how to get from your first sighting to a photo worth sharing.
Browse the gallery. See what real gear produces. Ask what it took.

"The best marine observation happens when you're not just a visitor to nature, but an active participant — paying attention, keeping records, and really seeing what shows up in your backyard."
Darren, founderOrigin
Sea Log grew from years of backyard marine observation and realizing there was no good way to keep track of sightings over time. A simple notebook wasn't enough — you wanted photos, dates, locations, weather conditions, and a way to share discoveries with other mariners. So we built a platform for that.
Sea Log is built on that same instinct: real birds, real sightings, real people who care about the hobby.
