    Abundance and Habitat Use of White-billed Starling (Onychognathus albirostris) in Human Inhabited Landscape: in case of Endayesus Campus Mekelle University, Tigray, Ethiopia.
    (Mekelle University, 2024-02-18) Gebrekidan Teka
    Ethiopia is known for its diverse and unique avifaunal resources. In modern sense the endemic and near endemic birds of Ethiopia can be used to provide early warning of environmental problems. This study was conducted from July 2023 to March 2024, covering both the wet and dry seasons. Limited research has been conducted on the abundance and habitat use of White-billed Starling. The objective of this study was to assess the abundance and habitat use of the White-billed Starling in the human-inhabited landscape of Endayesus Campus, Mekelle University Tigray Regional State, Ethiopia. The study employed a line transect point count method to collect data on bird populations. The line transect point count method was specifically used for the bird survey. The study area was categorized into three habitat types: built areas, farmland, and forestland. Three, two, and one transects were established in each habitat type, respectively. Data analysis was conducted using SPSS version 26 software for statistical analysis, Microsoft Office Excel for descriptive statistics, and generalized linear mixed models for advanced statistical modeling. The results indicate that the White-billed Starling exhibited the highest abundance during the dry season (1915 individuals) and the lowest abundance during the wet season (435 individuals) at Mekelle University Endayesus Main Campus. The highest abundance of White-billed Starlings was recorded in built-up areas during the wet (337) seasons. Conversely, the lowest abundance was observed in forest land (40) during the wet season and farmland (42) during the dry season. Human inhabited landscape appears to be a favorable habitat for White-billed Starlings and other bird species due to its abundant food resources and suitable nesting sites. The integration of White-billed Starlings into human-inhabited areas, such as urban landscapes, is crucial as these birds have been observed utilizing such environments for feeding, roosting, and breeding.
