The greylag gosling is now two weeks old and growing fast. The adult male has disappeared, leaving the female to bring up the gooselet (no, this isn’t a real word) on her own, but she seems to be doing a good job.
Update 12 June. Three weeks old and doing well!
Update 16 June. Unfortunately it looks as though we’ve lost the greylag gosling. We last saw it a week ago and briefly saw the mother fly off a couple of days ago (she never leaves the gosling on its own). Such is nature, though whether it was a predator like a fox we’ll never know.
