Abstract . Bird entanglement by plants may be globally widespread, but it is not a frequently studied phenomenon and records in different regions of the world are still scarce. During a short visit to the El Impenetrable National Park, Chaco province, Argentina, in October-November 2022, we recorded 15 incidental cases of birds entangled or trapped by fruits of the tree Pisonia zapallo. Our report involves 12 bird species from eight families, with a wide range of body sizes and masses. To our knowledge, this is the first documented report on this phenomenon in continental South America.
