Tanzania is one of Africa's best birding destinations. It has one of the largest species lists of any African country: over 1,100, of which over 800 species are resident, and nearly 200 are regular migrants. There are 22 species endemic to Tanzania, and a further 43 near-endemic. Migrants are present from November to April.
The birdlife in Tanzania is good year-round, but at its best from November to April when the migratory birds from Europe and northern Africa are present. At this time, many resident bird species are nesting and are in breeding plumage. The wettest months are March and April, when parts of the country may experience storms on a daily basis. The Wet season is also the hottest time of the year. This may make it uncomfortably hot on the coast. For wildlife viewing, the dry season is better.
All the well-known safari parks offer good birding opportunities, and specials can be found pretty much everywhere you go. The often-overlooked Arusha National Park has an amazing diversity of habitats that host an incredible list of 400 species in a small area. Lake Manyara offers a good variety of waterbirds.
