These are species with at least one recorded territory in Kenya, not a national checklist: a bird list from eBird or Avibase is more complete. The counts follow recording effort as much as wildlife, so a country with more visitors and more naturalists will show more of both.
The species with the most open occurrence records in Kenya, among those a photograph exists for. Most recorded is not most numerous: it rewards animals that are common, conspicuous and live where people go.
