Yes, there are pink flamingos in Bulgaria, and I remember that when my friends and I found out that they had appeared in the Atanasovsko Lake area, we went to observe them from afar in 2019 - I wrote about this here 🙂🚴.
This year, for the first time, three pink flamingos hatched in the lake area 😍- more info here
Glad you like my "cycling adventures". Thank you @alecaltab 🙏
