Trends in Richness and Occupancy of Ugandan Birds and Relation to Local Tree Cover Open
Changes in vegetation cover are occurring across sub‐Saharan Africa and can have substantial effects on ecological communities, but limited data make understanding status and trends difficult for many taxa. We surveyed birds for several de…

Conservation of vertebrates and plants in Uganda: Identifying Key Biodiversity Areas and other sites of national importance Open
Uganda is one of the most species rich countries in Africa because of the presence of several major biomes. However, it is also a country that has lost much of its natural habitat to agriculture. Uganda is a country that has been better su…

Densities and population sizes of raptors in Uganda’s conservation areas Open
Projected increases in Africa's human population over the next 40 years point to further, large-scale conversion of natural habitats into farmland, with far-reaching consequences for raptor species, some of which are now largely restricted…

Urban bird trends in a rapidly growing tropical city Open
Long-term studies of urban birds are relatively scarce, especially in Africa. We analysed trends in species richness and bird species occurrence over a 32-year period in Kampala, Uganda, in order to assess changes in the bird community in …

The Problems of Recording Bird Numbers in the Breeding Season as Pairs Open
As more and more species become threatened, the need to assess population sizes accurately in order to facilitate effective management actions increases. There is an extensive literature on counting birds, but no consensus on the most appr…

Developing biodiversity indicators for African birds Open
Biodiversity indicators are essential for monitoring the impacts of pressures on the state of nature, determining the effectiveness of policy responses, and tracking progress towards biodiversity targets and sustainable development goals. …

The increasingly urban status of the Cattle Egret Bubulcus ibis in Uganda, with some observations on its variable breeding seasons and associated species Open
Cattle Egrets Bubulcus ibis, long known for their expanding geographical range, have in recent years also become increasingly urbanized in Kampala, a city with over 1.5 million people, and elsewhere. First recorded roosting in Kampala over…

Another Continental Vulture Crisis Open
Vultures provide critical ecosystem services, yet populations of many species have collapsed worldwide. We present the first estimates of a 30-year Pan-African vulture decline, confirming that declines have occurred on a scale broadly comp…
