Birder AI (Beta)

What it's good at

• Seasonal patterns (e.g., "When do nighthawks peak here in early September?")
• Rarity history ("When was the last Snowy Owl in Westchester?")
• Hotspot comparisons ("Teatown vs. Cliffdale for Olive-sided Flycatcher")
• "Where/when to look" based on past notes and checklists

What it's not designed for

• not for real-time chase alerts
• not for photo/audio ID
• not for non-U.S. data

Try these (copy/paste)

• "When do Common Nighthawks peak in the Hudson River towns in early September? What time of day is best?"
• "Where have people found Connecticut warblers in Westchester? Any tips from species comments?"
• "Compare Teatown vs Cliffdale Farm for olive-sided flycatchers in fall. Are mornings better?"
• "Is 375 cormorants on the New Croton Reservoir unusually high for September? Break down by month and link similar checklists."
• "When was the last Snowy Owl in Westchester County? Show the last 10 records with notes."

Pro tip: Use Species + Place + Time window + Extras (links, notes, AM/PM, has_media).

Data & freshness

• Powered by eBird data (U.S. observations).
• Coverage through July 31, 2025. Public releases often have about a 1-month lag.
• "No results" can mean out of season, spelling/alt names, masked/sensitive species, or outside the current window.
