About this app

BirdRisk puts bird-strike risk on the map — the one layer your EFB doesn't have.

Bird strikes are a real hazard for general aviation, and no flight app shows you where the risk actually is. BirdRisk does one thing, and does it well: it turns open and scientific data into a single, glanceable bird-strike risk field over the terrain you're flying.

BirdRisk informs — it does not advise. It never tells you whether, when or where to fly. You, the pilot in command, stay in command. It only shows you the risk so you can see it before it sees you.

WHAT YOU GET
• A bird-strike risk field over Iberia, on a terrain map with hillshade
• How risk shifts across the day — dawn, day, dusk, night, at a tap
• An altitude rail: see how risk changes with your flight level
• Tap anywhere: the risk band and the reasons behind it, in plain words
• A legend that never confuses "low risk" with "no data"
• Your position on the map, only if and when you ask for it

WHY IT'S DIFFERENT
The risk isn't a guess. It's a calibrated model built on the real drivers of strikes in Iberian skies — soaring raptors over midday thermals, migratory corridors at dawn and dusk, wetlands and colonies — weighted by what actually brings aircraft down, not by a flat rule of thumb. The same model, verified vector by vector, that powers BirdRisk for iOS.

WHO IT'S FOR
VFR and general-aviation pilots — light aircraft, ULM/microlight, autogyro, glider — who want one more thing on their side before they line up.

IMPORTANT
BirdRisk shows bird-strike risk only. It is not a navigation, air-traffic, weather or flight-safety system, and it does not replace official sources (NOTAMs, ATC, weather, AIS) or your own judgement.

PRICE
Free to use. BirdRisk Pro will later become an optional subscription. Terms: https://birdrisk.com/terms · Privacy: https://birdrisk.com/privacy
Bird-strike risk for pilots, on the map. It informs; you decide.

What’s new

Risk map calibration fix.

During peak migration season the map was placing far too much of Iberia in the high-risk band, which drowned out the areas that actually matter. Risk bands are now calibrated against current-season data, so high risk means high risk again.

This changes where the band thresholds sit, not how risk itself is calculated.
