While we were walking through a park in the Yeong-do part of Busan, Pat spotted these Magpies (P. pica sericea). She’d seen some earlier near our lodging, but this time we both got to see them and I snagged pictures.
Although we’ve seen a few other birds, we’ve only been able to identify them in general terms (e.g., rock dove, gull). We don’t have a book with us nor do we have the benefit of a guide. But, it’s still good to see a few birds.
Wikipedia has an multi-paragraph entry on these birds.
