07h35-08h00 : Spot du bec de Perroquet (baie d'Authie nord). MĂ©tĂ©o: nĂ©bulositĂ© 4/8, tempĂ©rature 12 ℃ Ă  15°C, SSE 3Bft Ă  SE 4 Bft. Observateurs : Thierry Rigaux et François MĂ©ranger. NB : des groupes d'Ă©tourneaux sont sans doute passĂ©s inaperçus en mer, tel le groupe de 8000 vu Ă  Quend. Beau passage de Tarins. Les Pinsons du Nord ne sont pas dĂ©tectĂ©s ni comptabilisĂ©s convenablement. Les Bruants des roseaux non plus. Les effectifs fournis pour ces espèces sont des minima bien en deçà vraisemblablement du flux rĂ©el. Ce ne sont pas du tout des estimations. L'arrivĂ©e sur spot a lieu Ă  8h00, les 25 mn prĂ©cĂ©dentes correspondant Ă  la marche d'approche.,15h00-16h00 : y compris trajet de retour Ă  la voiture
