Raptor Migration: Steppe Eagle and Ngulia Ringing Station

Every October and November, millions of birds of prey pour south out of Europe and Central Asia into East Africa — and one hillside lodge in Tsavo West has become the best place on the continent to watch it happen up close. Steppe eagles, lesser spotted eagles, and honey buzzards ride the same corridor that funnels raptors down through the Middle East and the Horn of Africa, turning a handful of weeks each year into the richest raptor-watching window on the safari calendar. Explore our Kenya safaris to time a visit to the migration.

A Continental-Scale Migration Passing Through East Africa

Each autumn, huge numbers of birds of prey leave their breeding grounds across Europe and Central Asia and head south for the winter. The steppe eagle, breeding on the steppes of Kazakhstan and southern Russia, is the most numerous single species on this route, but it travels alongside lesser spotted eagles, European honey buzzards, western marsh harriers, and Montagu’s harriers, among others. Their route funnels them down through the Bosphorus, the Middle East, and the Horn of Africa before spreading out across the East African savanna on the way to wintering grounds further south — a round trip that can cover well over ten thousand kilometres.

For safari visitors, this migration is most visible during a roughly six-week window in October and November, when the Serengeti’s short-grass plains and the Masai Mara’s open grassland receive a wave of arriving raptors resting and refuelling before continuing their journey.

Ngulia: Africa’s Most Important Bird Ringing Station

The single best place to witness this migration up close is Ngulia Safari Lodge, perched in the Ngulia Hills of Tsavo West National Park. The hills form the first significant high ground migrating birds encounter on their southward journey, forcing them to either climb over or skirt along the ridge line — and the lodge sits right on that flight path.

What makes Ngulia truly exceptional is a combination of geography and weather: during the October-November peak, low cloud and mist frequently descend onto the hills at night, and the lodge’s floodlights become the only visible point of light for disoriented migrating birds, drawing them in by the thousands. On the busiest nights, the lodge’s lawn can be carpeted with birds. A bird-ringing station has operated here continuously since 1969 — one of the longest-running and most significant in Africa — using mist nets around the floodlit grounds to catch, ring, measure, and release migrants unharmed, usually within half an hour of capture. Over the decades, ringing recoveries have confirmed that birds passing through Ngulia have bred as far away as Finland, Sweden, Germany, and Russia. Visitors can often join a ringing session at the lodge during peak season — a rare chance to hold a bird that bred in Scandinavia and will winter in southern Africa.

Where Else to Watch the Migration

The Serengeti’s Ndutu area, on the short-grass plains straddling the southern Serengeti and Ngorongoro, is a major landing and refuelling site — arriving steppe eagles, lesser spotted eagles, and honey buzzards settle here in groups to feed on the locusts and grasshoppers that peak in abundance at the same time of year, building up fat reserves before continuing south.

The Masai Mara’s Oloololo Escarpment is another highlight, where October updrafts concentrate migrating raptors into visible thermal columns, sometimes numbering in the hundreds, rising along the escarpment edge during the mid-morning hours. Amboseli’s open plains, sitting near the base of Kilimanjaro at high altitude, also serve as a resting point for steppe eagles before or after crossing the mountain.

Even outside the migrants, East Africa’s resident raptors remain on territory throughout this period, including the striking black-and-white Verreaux’s eagle, tawny eagle, Wahlberg’s eagle, and long-crested eagle — meaning a single November game drive combining migrants and residents can turn up an unusually high number of raptor species in just a few hours.

Planning a Raptor Migration Safari

A dedicated raptor circuit typically combines a couple of nights at Ngulia Safari Lodge in Tsavo West for the mist-netting and ringing sessions, a stop at the Masai Mara’s Oloololo Escarpment for the updraft spectacle, and a few nights on the Ndutu plains in the southern Serengeti for ground-level views of resting migrants — together covering the migration’s aerial, ground, and research dimensions in about a week.
