eBird API Setup

Your personal eBird API key stays in this browser only and is deliberately excluded from Big Year backups.

In the hosted PWA, eBird requests use the same-origin Bird Commander Cloud API. Your personal eBird key remains stored only in this browser/device.

Current Alerts

Sorted by Big Year chase score, then freshness and distance.

How the score works

The local score favors birds you still need, fresher reports, shorter distance from Two Rivers, repeat reports at multiple nearby locations, higher ABA rarity codes, and reviewed/valid observations. It is a chase-priority score, not a probability of success.

Chase Board

No cost math. Just rarity, freshness, confidence and whether you still need it.

eBird Import

Import My eBird → Download My Data. Only observations dated in 2027 are applied to this Big Year.

An eBird observation marks the bird as encountered, but eBird's spreadsheet does not reliably say whether you saw it or heard it. Classify 👁 / 👂 afterward. Media catalog numbers are preserved as evidence without guessing whether they are photo or audio.

Backups

JSON is the full-fidelity backup. CSV is convenient for spreadsheets.

Run Cloud Check after deployment to verify API, ABA, images, PWA security and device storage.

The tracker shell and your locally stored records remain available offline after the first successful hosted load. Live eBird, weather, geocoding and map tiles require internet. Recently used reference bird images can be retained by the PWA cache.
