To Cede or Not to Cede the Nest to Your Partner

Update for Monday, April 1, 2024

Astrid gently pushes Ares off the nest

Throughout the years, we’ve observed an intriguing behavioral interplay between Astrid and Ares. Sometimes, when either bird comes to the box with the intention to take over incubation duty from their partner, they are rebuffed. When one of them is settled-in and incubating the eggs, they sometimes exhibit a reluctance to relinquish the nest. Initially, Astrid had no qualms about ousting Ares. Whenever she wanted a turn, she would assertively displace him without much ado. However, in recent years, Astrid has adopted a gentler approach towards displacing her partner. Now, she spends time beside him, engaging in beak swiping before delicately nudging him out. As a last resort, she may lightly step on his wing or tail feathers – that is, if gentle persuasion fails. Conversely, Ares has undergone a remarkable transformation in his behavior. He has grown more audacious and now mirrors Astrid’s old methods when ousting her, sometimes lacking the gentleness. Nevertheless, if Astrid is resolute about staying put, she communicates her intent with a determined gaze, prompting Ares to acquiesce and depart.
