Tools and field notes for birders

Pull up a bench.

A bench is where you watch birds — and where you get work done. BirdBench builds fast, honest tools for both: nectar math, feeder matching, nest-box specs, and a life list that stays on your device.

The Bench

Four tools, no accounts, no tracking. Everything runs in your browser.

  • Hummingbird Nectar Calculator

    The 4:1 recipe scaled to your feeder — sugar in cups and grams, plus a cleaning schedule by temperature.

  • Seed & Feeder Matcher

    Pick the birds you want. See which seed and feeder serve the most of them — trade-offs included.

  • Nest Box Spec Finder

    Published hole sizes, floor dimensions, and mounting heights for 19 cavity nesters. Print the spec card.

  • Lifer Log

    A life list that never leaves your browser. Add sightings, see stats, export CSV or JSON anytime.
