• API_NINJAS_KEY: API Ninjas key for additional facts

Common region codes for the eBird API:

• US-CA - California, USA
• US-NY - New York, USA
• GB - United Kingdom
• AU - Australia
• CA-ON - Ontario, Canada

// Get random regional bird
const response = await fetch('/api/birds/random?region=US-CA');
const bird = await response.json();
console.log(`${bird.name}: ${bird.fact}`);

// Get bird by coordinates
const nearbyBird = await fetch('/api/birds/random?lat=40.7128&lng=-74.0060');
const birdData = await nearbyBird.json();

import requests

# Get random bird fact
response = requests.get('https://your-api-url/api/birds/random')
bird = response.json()
print(f"{bird['name']}: {bird['fact']}")

# Get regional birds
regional_response = requests.get('https://your-api-url/api/birds/region/US-CA')
birds = regional_response.json()
