Noteworthy record of the Hook-billed Kite Chondrohierax uncinatus predating the invasive snail Rumina decollata in Cuitzeo lake. Huitzil [online]. 2022, vol.23, n.1, e635.  Epub 31-Out-2022.

We present the first records of the Hook-billed Kite (Chondrohierax uncinatus) for the Cuitzeo lake in Michoacán. We observed a pair of Hook-billed Kites in April and September 2018, perched in the same woodlot of Prosopis laevigata (mezquite). In September the female was observed preying on the invasive Rumina decollata snail. This is noteworthy as this invasive snail can attain high densities and is harmful to biodiversity as it predates other gasteropods and is a crop pest. This record of the Hook-billed Kite raised to thirteen the number of diurnal raptor species recorded for the Cuitzeo area. Considering that it is unusual to observe cases in which an invasive species is predated by a native species, future studies should examine this biotic interaction.
