However, as surveys provided richer information, it was decided to publish this dataset on its own. Each survey refers to a complete presence-only species list (called "event" in the dataset), each recorded over ~1km and during ~1hr. Four surveys were performed successively over a morning from 6am to 10am covering a transect. Each of the 23 transects was repeated once a month (grouping called "session") from May 2020 to May 2021. The study area covers the habitat between Arabuko-Sokoke Forest and Mida Creek. Surveys were collected by bird guides from the area (Daniel Kazungu, Juma Badi, Kibwana Ali, Saddam Kailo and Mohammed Ali) and organized by Kirao Lennox, Raphaël Nussbaumer and Colin Jackson from A Rocha Kenya. **Summary of count statistics.** * Number of transects : **23** * Number of sessions: **11** * Number of events (surveys): **873** * Number of occurrences (sightings): **29195** * Number of species: **217** **Purpose:** - Collect standardized data on common species between the forest habitat and the creek/coastal habitat. - Collect baseline data with a reproducible protocol in order to assess the change of avifauna over time. - Assess the impact of deforestation on the 'shambas' (fields/farms). **Type of data** This dataset is published as a Darwin Core Archive using a sampling event dataset type. **Data structure** - The raw data was collected on the field using the Birdlasser application, and stored in `data/birdlasser_files`. - `data/metadata.xl …
