Best-scoring areas right now, ranked by conditions and the latest survey counts.
Ranked by Hunt Score adjusted for confidence — an area backed by real survey counts outranks one scored on weather alone at the same number.
What's pushing birds south across the Mississippi flyway — freeze, fronts and north wind — with the measured counts on top. Click the map to open it full size.
Colorado is in the Central flyway. The heatmap covers the Mississippiflyway for now, so it isn't showing your area yet — the conditions, outlook and shooting light above are for Colorado. The other three flyways are coming.
Change since each area’s previous survey — arrow up filling, arrow down emptying, and the number is birds per day.
22 of 92 areas have only one stored survey, so they have no change to show — they appear grey.
No recent survey count for this area — the score below rests on weather and water only.
An engineering estimate that blends live weather, water, and the latest official survey count — not a validated prediction. Missing inputs lower confidence, not the number.
It's 81°F at John Martin Reservoir Wildlife Area, Colorado with 15 mph wind from the ESE. No significant front in the next few days (daytime highs hold steady). Winds are up but not out of the north, so less of a migration push.
Auto-generated from live NWS/USGS data. No recent survey count for this area, so this describes conditions, not confirmed birds.

Scored over the dawn window (5–10am local) from the NWS hourly forecast, using the same model as the Hunt Score. Water and survey counts don't have a per-day forecast, so they are held level across the strip — the day-to-day movement here is weather.
New moon
0% lit — dark nights, better odds of a morning feed
