Occurrence description
Buiten broedtijd
Noordse Pijlstormvogels vertonen zich voor de Nederlandse kust van juni tot en met oktober. Bij krachtige aanlandige winden worden soms enkele tientallen per dag gezien op de zeetrektelposten. Waarnemingen in juni-juli beperken zich grotendeels tot de Noord-Hollandse kust; tijdens een trekpiek in september en de eerste helft van oktober zijn waarnemingen ook elders langs de kust mogelijk. Waarnemingen in het binnenland zijn extreem zeldzaam, al vertoont de soort zich af en toe diep op de Westerschelde.
Birds directive
Conservation status
The Birds Directive focuses on the conservation of all naturally occurring wild bird species in Europe, including the Manx Shearwater.
This means that EU Member States must take measures to maintain or bring the populations of these species to a level that corresponds in particular to ecological, scientific and cultural requirements.
The Birds Directive requires Member States to maintain habitats for birds of sufficient size and quality, including through the designation of Special Protection Areas for the benefit of the European Natura 2000 network. No special protection zones have been designated for the Manx Shearwater in the Netherlands. The national population must be able to maintain itself at a favorable level.
What is the methodology to assess the conservation status of birds
non-breeding bird
The conservation status of the Manx Shearwater as non-breeding bird in the Netherlands is unfavourable (inadequate).
