The diversity of bird life in Ruaha, more than most other East African Parks, is extraordinary; its geographical location meaning that it is visited by both northern and southern migrants. These include the Red-billed Wood Hoopoe, Violet-crested Turaco, Racquet-tailed Roller, Red-billed Firefinch, Dickinson’s Kestrel and Pel’s Fishing Owl. It is during the green season that starts in January and continues into April that the park is transformed into a green oasis with flowing rivers and thick vegetation. Spectacular volumes of birds can be seen with approximately 526 bird species found here (more than half of those found in the whole country!). The green season is appreciated as the most interesting for birders.
