Comments :
08h00-09h00 : hors protocole : site du bec de Perroquet en baie d'Authie. Météo : assez doux. 8°C à 10°C. Vent SSE 1-2 Bft, un peu plus fort en fin de matinée (2Bft). Couvert (8/8) en début de session puis éclaircies (4/8). Observateur : Thierry Rigaux. NB : observations assez comparables avec celles effectuées en baie de Canche à la pointe de Lornel par Marc Briet et Eric Gesquière,09h00-10h00 : Les Etourneaux passent d'abord par quelques très grands groupes au dessus de la mer pour la plupart. Ils pourraient échapper à la vue d'un observateur pas suffisamment vigilant ou n'ayant pas une acuité visuelle suffisante. Peut-être en ai-je loupé ! Un autre grand groupe passe le long du trait de côte. Le passage des Pinsons est encore important pour la saison. Ils passent à différentes hauteurs, certains migrant haut et pouvant passer aussi inaperçus.,10h00-11h00 : Passage notable de farlouses (sans doute quelques spioncelles et/ou maritimes non comptabilisés mais minoritaires) et de brua
