“…Several wild bird species were affected during this last wave, including African partial-migrants, like spur-winged goose and sacred ibis 11,37,38 . However, waterbird movements within Africa are poorly understood and are highly variable among species [39][40][41][42] , making it difficult to assess their potential role in virus diffusion. Nor can we exclude that the viruses identified in west, east and south…”

“…Our data indicate that intra-Africa wild bird migration appears to be the most likely cause of virus spread. Afrotropical waterfowl movements are complex and are mainly driven by the availability of food and water 62 , as demonstrated for some trans-equatorial migrant species 39,40 . The abundant rainfall during the 2016-2017 Sub-Saharan and southern African rainy seasons, which created temporary wetlands, attracting a large number of birds, coupled with the anomalous drought that affected central Africa in October-December 2016, might have shaped the intra-African movements of wild birds during this period.…”

Disentangling the role of Africa in the global spread of H5 highly pathogenic avian influenza

The role of Africa in the dynamics of the global spread of a zoonotic and economically-important virus, such as the highly pathogenic avian influenza (HPAI) H5Nx of the Gs/GD lineage, remains unexplored. Here we characterise the spatiotemporal patterns of virus diffusion during three HPAI H5Nx intercontinental epidemic waves and demonstrate that Africa mainly acted as an ecological sink of the HPAI H5Nx viruses. A joint analysis of host dynamics and continuous spatial diffusion indicates that poultry trade as well as wild bird migrations have contributed to the virus spreading into Africa, with West Africa acting as a crucial hotspot for virus introduction and dissemination into the continent. We demonstrate varying paths of avian influenza incursions into Africa as well as virus spread within Africa over time, which reveal that virus expansion is a complex phenomenon, shaped by an intricate interplay between avian host ecology, virus characteristics and environmental variables.

“…Both species migrated into central Africa during the nonbreeding season but African cuckoos followed a southeasterly direction whereas common cuckoos flew mostly south and the final non-breeding sites of the African cuckoos were more northerly. Studies have revealed varying patterns in the type of non-breeding grounds used by intra-African migrants with for example a Wahlberg's eagle breeding in savannah woodlands and spending the non-breeding season in Sahelian Africa (Meyburg et al 1995) and Abdim's storks migrating from Sahelian breeding grounds to mixtures of grasslands and woodlands (Jensen et al 2006).…”

“…Many of these migratory species are breeding visitors within the savannahs of the region. Yet, only for a few of these species is there detailed information regarding timing and duration of migration between breeding and non-breeding grounds (Meyburg et al 1995, Jensen et al 2006. Such knowledge can contribute to understanding migratory behaviour in general as well as to conservation of migrants (Runge et al 2014) which are declining overall (Bairlein 2016).…”

Despite many bird species migrating regularly within the African continent, in response to rainfall and breeding opportunities, documented evidence of the spatiotemporal patterns of such movements is scarce. We use satellite telemetry to document the year round movement of an intra-African migrant breeding in the savannah zone of sub-Saharan Africa, the African cuckoo. After breeding in central Nigeria, the birds migrated to more forested sites in the Adamawa region of Cameroon (n = 2) and western Central African Republic (n = 1). Departure from the breeding ground coincided with deteriorating environmental conditions whereas arrival at the non-breeding sites matched period of increasing vegetation greenness. Migratory movements generally occurred during dark hours. In total, an average distance of 748 km in 66 d was covered during the post-breeding migration and 744 km in 27 d during return journey with considerable individual variation and with more stopover sites used during postbreeding migration. The diversity of migration routes followed suggests a relatively variable or flexible initial migration strategy, high individual route consistency as well as high fidelity for non-breeding grounds.
