Peregrines are generally solitary birds. Even when they are both roof, you will notice that they are usually each at the far end from each other. However, peregrine couples have pair-bonding rituals throughout the year: prey bringing, ‘bowing’, preparing the scrape.
In this video the actual bonding ritual of bowing and interacting with your partner by calling and moving around them is clearly demonstrated. There is some ‘tip-toeing’ by Gimbir and a bit of faux aggression by Diamond and that is quite normal. She is much bigger and stronger than Gimbir, as are all females and he has to be respectful in his interactions with her. Pair-bonding lasts from under a minute to over two hours and this one is about eight minutes, which is longer than average.
Girri is still learning to hunt by chasing her parents around, mostly at dusk and dawn. Here is a good example of dusk training flights.
