The arrival of the house crow (Corvus splendens) in Brazil: An unwelcome presence and the need for immediate control measures
摘要
This study reports the first confirmed sighting of Corvus splendens (house crow) in the municipality of Itaguaí, Rio de Janeiro, Brazil. Native to the Indian subcontinent, C. splendens is among the most successful invasive birds globally, with a growing presence across multiple continents. Its strong association with urban areas, high ecological adaptability, and omnivorous diet allow it to thrive in human-modified environments. In April 2025, an adult individual was observed and photographed near the Port of Itaguaí, a likely entry point via maritime transport. Similar introduction pathways have been documented across South America, where sightings are often clustered near major ports. The species poses significant risks to native fauna through competition and predation and has proven difficult to control once established. Given its invasive potential and history of rapid spread, this observation underscores the need for early detection, enhanced monitoring in port regions, and targeted management strategies to prevent further establishment in Brazil.
