Thanks to A Rocha Kenya, Kenya Wildlife Service, all conservation organisations, the tourism industry, and well-wishers for your great efforts in controlling the crow population. We have been receiving positive feedback from the local community. Please keep up the good work. 👏🌿🐦
Invasive species management is an important part of conservation. When a species is introduced into an ecosystem where it does not naturally belong, it can disrupt ecological balance and negatively affect native wildlife and people.
The Indian House Crow is one such species.
Native to the Indian subcontinent, House Crows were introduced to East Africa in the 1890s and first recorded in Kenya in Mombasa in 1947. Since then, their population along the coast has grown rapidly and spread across urban centres and coastal towns. Overall populations along the coast are estimated to be in the tens of thousands.
House Crows have serious impacts on native ecosystems and local communities. They prey on eggs and chicks of indigenous birds, compete with native species for food and nesting space, spread disease, contaminate food areas and create challenges for tourism facilities, markets and public spaces.
Because of these impacts, intervention became necessary.
The Crows No More! programme, led by Kenya Wildlife Service and implemented by us, was established to reduce and control the invasive population through targeted management strategies.
Since we began participating in systematic control efforts under this programme: including monitoring roost sites, mapping populations and implementing regulated control measures, the programme has shown encouraging results. Local observations indicate reduced densities in key areas and improved conditions for native species.
This is practical conservation in action, responding directly to an ecological imbalance with deliberate, science-informed intervention.
The work continues, and we remain committed to monitoring results and adjusting strategies where needed. You can keep up with the updates from the field here: https://www.arocha.or.ke/crows-no-more-project/
