Interpretation

Bird concentration hazard on all runways and approach surfaces with density level 5 from the surface to 3000 ft; most dense within 0–200 m from runway starts and on approach surfaces (0–200 m most dense, 200–400 m dense, 400–1000 m low dense). Expect large groups of stork, eagle, hawk, white wagtail, swallow, swift moving ESE to WNW, and groups of duck, goose, pigeon, jackdaw, starling, small songbirds. Cormorant groups likely at runway thresholds and approach surfaces, especially during sunrise and sunset and partially during the day.
