This female swan is incubating 10 eggs, and this is her mate. But unbeknownst to her, he's been courting another female swan nearby. And she is heading this way. Now, this is going to be interesting because the intruder is actually their offspring from 2023. The female postures, leaving the nest and giving chase around the reed bed. And thankfully, all the eggs look okay. With the intruder seen off, the female joins him back on the nest. Peace has been restored for now.
