The recent note concerning the predation of a Black-headed Gull Chroicocephalus ridibundus by a Carrion Crow Corvus corone (Brit. Birds 113: 239) brought to mind an incident that I witnessed in Parc Monceau, in central Paris. Around midday on 3rd March 2020, my attention was drawn to the calls and behaviour of a distant pair of Carrion Crows, perched at a height of c. 20 m in an Oriental Plane Platanus orientalis. One of the birds would regularly drop a short distance from its perch and hang upside down from a tree hole in a nearby bough. Through binoculars I was astonished to find that the object of the crows’ attention was a solitary and strangely inactive Rose-ringed Parakeet Psittacula krameri, which appeared to fully occupy the tree hole.
