The Pin-tailed Wydah bird is striking and improbable looking. It is one of my favorites.
This one heads out to forage along the roadside in the Serengeti but I've seen them in Dar es Salaam as well.
They have a beautiful rhythmic pulsing flight, no doubt caused by the aerodynamic challenges inherent in carrying such a fabulous tail.
I wish I knew more about them. I'm glad they are fairly common in Tanzania.
