Great blue herons in the process of building the nest - very captivating to observe their behaviour - the male brings in branches and passes them on to the female (from beak to beak) and then the female rearranges the branches on the nest Assez intéressant que d'observer le comportement des grands hérons lors de la préparation du nid - le male apporte les branches qu'il transfère à sa copine, bec à bec, elle arrange ensuite ces branches dans le nid
