Abstract
BackgroundAgroforestry is an integrated land-use system that plays a great role in the conservation of landscape biodiversity. The study aimed to assess the composition and diversity of avian species along with different habitat types of agroforestry in Kibet Town, Southern Ethiopia.MethodsFour habitat types of agroforestry system which are home gardens, live fences, parkland, and eucalyptus woodlot were identified. Line transects were used for bird surveys. The Shannon diversity index (H′) and species evenness index (E) were used to compare diversity among habitat types. A similarity percentages (SIMPER) test was carried out to identify the main species and feeding guild that typified each habitat type. The overall significance was assessed with the ANOSIM test using PAST (version 4.03).ResultsA total of 50 bird species belonging to 28 families and 10 orders were recorded. Order Passeriformes (67.3%) had the highest number of species. Bird community composition differed among habitat types. The dissimilarity was mainly due to White-browed robin-chat (Cossypha heuglini), Streaky seed-eater (Serinus striolatus), Village Weaver (Ploceus cucullatus), African Paradise-Flycatcher (Terpsiphone viridis), and Black-Headed Paradise Flycatcher (T. rufiventer). The finding also revealed that insectivore was the dominant feeding guild.ConclusionsThe present study shows evidence that more insectivore bird species use different types of agroforestry as habitat and foraging sites. So, any concerned bodies who have engaged in avian conservation should give special consideration to this modified landscape.
Highlights
Agriculture is a major manipulator of biodiversity and has the potential to contribute to the protection of biodiversity [18]
Agroforestry is recognized as an integrated land-use that can directly enhance agro-biodiversity and contribute to the conservation of landscape biodiversity, while at the same time increasing, diversifying, and sustaining rural incomes [24, 39]

Summary
Agriculture is a major manipulator of biodiversity and has the potential to contribute to the protection of biodiversity [18]. To advance conservation and production goals, agricultural practices should be compatible with biodiversity [31]. Agroforestry is recognized as an integrated land-use that can directly enhance agro-biodiversity and contribute to the conservation of landscape biodiversity, while at the same time increasing, diversifying, and sustaining rural incomes [24, 39]. It is a production system characterized by the combination of forestry and agriculture [42]. Agroforestry is an integrated land-use system that plays a great role in the conservation of landscape biodiversity. The study aimed to assess the composition and diversity of avian species along with different habitat types of agroforestry in Kibet Town, Southern Ethiopia
