tyran huppé / great-crested flycatcher

il est perché au-dessus de son nid situé dans le tronc de cet arbre mort. J'ai remarqué que le sommet du tronc ressemble à une tête d'oiseau qui regarde vers le ciel. Donc, il est perché sur son bec?
he is perched above his nest located in the trunk of this dead tree. I noticed that the top of the trunk looks like a bird's head looking skyward. So he's perched on his beak?
