Comments :
08h05-09h00 : Site de référence (sur le banc de l'Ilette sensu stricto). Météo : doux. Vent presque nul SE en début de séance passant au SSW en forcissant vers 10h30. Vent soutenu 3-4 Bft ensuite. Nébulosité fluctuante avec ciel essentiellement bleu en début de session puis 6/8 vers 10h mais à nouveau quasi nulle vers 13h00. Très beau passage de Pinsons des arbres et de Pinsons du Nord avec toujours une grande difficulté à quantifier ces derniers. Vols de Pinsons haut et près la mer en début de matinée, s'abaissant en cours de matinée avec le renforcement du vent. Nb : sur le trajet d'accès au spot, environ 25 Mauvis, 6 Musiciennes, 5 Merles noirs, 2 Bruants des roseaux,09h00-10h00 : Les effectifs de Tarins et Pipits farlouses sont vraisemblablement nettement sous-estimés. Mêlés aux Pinsons. Il en va probablement de même des Alouettes lulus dont j'ai pu voir qu'elles étaient souvent intégrés à des groupes de Pinsons, y compris en bord de mer.
