eBird API

Animals / API Key Intermediate HTTPS
Varies by plan (check documentation)

Overview

eBird API from Cornell Lab provides real birding observation data including species sightings, locations, and notable birds by region. Great for nature apps and data visualization projects.

Beginner Tip

Get your free API key at ebird.org/api/keygen. Always include it as header X-eBirdApiToken, not as a query parameter.

Available Data

eBird data via REST API

Example Response

JSON Response
{
  "name": "eBird",
  "data": "eBird-specific information and attributes",
  "source": "eBird"
}

Field Reference

speciesCode eBird species code such as "norcar" for Northern Cardinal
comName Common English name of the bird species
sciName Scientific Latin name of the species
locName Name of the location where the bird was observed
obsDt Date and time of the observation in ISO format
howMany Number of individuals observed (may be null if not counted)

Implementation Example

Request
const url = "https://documenter.getpostman.com/view/664302/S1ENwy59";
// Replace headers or query params with the values required by this API.
const response = await fetch(url, {
  headers: {
  "X-API-Key": "YOUR_API_KEY"
  }
});
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data);

What Can You Build?

Note: These code examples are AI-generated and unverified. Always refer to the official API documentation for accurate usage.

Common Errors & Troubleshooting

403 Forbidden Missing or incorrectly passed API key
Set header X-eBirdApiToken: YOUR_KEY; the token must be in the header not the query string
Empty results array No observations reported in that region in the past 14 days
Try a larger region code such as US-CA for California instead of a county code
Invalid region code error Using wrong region format such as "California" instead of "US-CA"
Use eBird region codes: country (US), state (US-CA), or county (US-CA-037)

Metadata Score Breakdown

Estimated from metadata — endpoint not independently tested

This score is estimated from observable metadata — HTTPS support, authentication model, declared CORS, and documentation reachability — because the API requires authentication or exposes no publicly testable endpoint. The five-signal breakdown is only shown for live-tested APIs.
