BirdRisk shows the live bird-strike risk over your area and along your route, leg by leg, shifting from dawn to dusk — soaring raptors over midday thermals, migratory corridors at first and last light, wetlands and colonies. See it before it sees you. It informs; it doesn't advise. Built for VFR & GA pilots — light aircraft, ULM, autogyro, glider. See what a risk reading rests on.
Every risk reading shows its receipt — sightings in the cell, date of the latest, and source.

Built for pilots flying Spain and Portugal, BirdRisk does one thing well: it tells you how risky birds make your route — on the ground when you plan it, and in the air as you fly it — clearly enough to glance at on a kneeboard. Every reading shows the bird sightings behind it — how many are recent in that cell, when the latest one was recorded, and which open database it came from.
Draw a route straight on the map with your finger — then add, move or remove waypoints until it matches your plan. BirdRisk colours each segment by bird-strike risk, by hour of day and altitude band, from real migration, wetland and radar data. Sketch an area instead and it reads the risk inside it.
In the air, your aircraft tracks over the 3D terrain with the risk right now and just ahead — plus a quiet heads-up the moment you enter a busier area. A Home Screen widget carries the current risk before you even open the app.
BirdRisk informs — it never tells you to go or no-go. The final call is always yours, the way aviation works.
Most tools hand you a number and ask you to trust it. BirdRisk hands you the number and what it rests on. Tap any area and the card opens its books: how many recent bird sightings sit in that cell, when the latest one was recorded, which open scientific database it came from, and what is driving the level. The number is yours to judge, not just ours to assert.
Example of the risk card. Every value is read from live data — none of it is estimated to fill a gap.
The map is just as plain about its own limits. It tells you the scale it is claiming — a coloured area covers a grid cell, not a single point. When a hazard layer cannot load, it says so, and the risk shown is a lower bound: an absent layer is never an all-clear. And “no data here” is never dressed up as low risk.
Built on the same data ornithologists and controllers use.

BirdRisk colours your corridor and gives you one clear level: low, medium, high or critical.
You have the level, the hours, and the evidence behind them. BirdRisk never decides for you.
In flight, BirdRisk follows your aircraft over the terrain and reads the bird-strike risk where you are — and where you're heading. A quiet banner flags the moment you cross into a higher-risk area. Kneeboard-clear, no menus.
Every risk area is explainable. Tap it to see the level, the coordinates, the sightings behind it and the dominant factor — then open the hourly trend to see how it changes hour by hour. Aerodromes sit on the map too: tap one for its own risk trend through the day. Birds move at dawn and dusk; BirdRisk shows you when.
Hillshade or satellite, day or dusk — BirdRisk stays glanceable over the terrain you actually fly.

A bird strike is a collision between an aircraft and a bird in flight. In general aviation most reported strikes happen at low level — take-off, approach and low-level cruise — and bird movement is typically highest around dawn and dusk. BirdRisk shows where and when that exposure is highest along the route you fly.
Yes. Over Iberia the picture shifts through the year: migratory passage in spring and autumn, griffon vultures and other soaring raptors riding midday thermals in the warm months, wintering flocks over wetlands and reservoirs. BirdRisk doesn't work from a seasonal average: it reads the recent sightings recorded in the cell you tap — with their date and source — and opens the hourly trend behind them.

No. BirdRisk gives you the risk level and the data behind it, but the go / no-go decision is always yours — that's how aviation works.

Every risk reading opens its receipt: sightings in the cell, date of the latest, source, and the scale it is claiming — a grid cell about 11 km across. When a hazard layer can't load, the app says so and the level shown is a lower bound.
