Birds migrate year-round in a broad front over the Netherlands, with dense migratory routes along the coastal region and the Dutch-German border. Birds also commute between sleeping/breeding and foraging sites all year round and in all regions of the Netherlands. Colliding with birds, especially large and or flocking ones, could jeopardize the safety of the aircraft, its crew and passengers.
Spring migration takes place in the months March, April and May and peaks during strong SW/W winds. Migration is less likely during periods of rain.
Autumn migration takes place in the months mid-August, September, October and Mid-November and peaks during strong NE/E winds. Migration is less likely during periods of rain.
High bird densities occur up to altitudes up to 6000 FT AGL during the night and 4000 FT AGL during the day. Local bird movements around sunrise and sunset occur up to altitudes of 1000 FT AGL.

The FlySafe Bird Avoidance Model (https://www.flysafe-birdtam.eu) provides near real-time and forecast information on large scale bird movements over Belgium, Germany and the Netherlands. The data are disseminated via BIRDTAMs (bird notice to airmen) to military pilots.
To achieve more comprehensive statistics of bird strikes, the Civil Aviation Administration is collecting information on bird strikes. All pilots on flights within Amsterdam FIR are therefore requested to report all cases of bird strikes or incidents where a risk of bird strike has been present. Information about the reporting process can be found on https://www.ilent.nl/onderwerpen/voorvallen-luchtvaart.
Sensitive fauna are animals that are sensitive to disturbance by human activities like, among others, overflying aircraft:
To avoid disturbing sensitive fauna, pilots are strongly advised not to cross areas with sensitive fauna below 1000 FT AGL. The areas with large flocks of birds and/or seals are depicted on chart ENR 6-5.3 and on aerodrome visual approach charts. In paragraph 3 all locations of these areas are listed by name, including the season and the minimum altitude to cross these areas.
To protect the sensitive fauna in the Waddenzee, by Decree the following applies:
These altitude restrictions do not apply to:
For flights below 1500 FT AGL in the Waddenzee area, two permits are required:
In view of the protection of the sensitive fauna in the Zeeland Delta, flights above the following areas are prohibited below 1000 FT AGL:
