Helminths of the hooded crow ( <i>Corvus cornix</i> ) in cities and beyond: a descriptive analysis of historical and contemporary data from Ukraine

This study presents data on helminth communities from 93 Hooded Crows (<i>Corvus cornix</i>). The dataset includes historical and contemporary records from three localities in Ukraine with different levels of urbanisation: Kyiv, the Middle Dnipro River, and Polissya. Thirty-two helminth species were identified, including 14 trematodes, six cestodes, 11 nematodes, and one acanthocephalan. The nematodes Eufilariella delicata and <i>Hadjelia truncata</i> are documented in Hooded Crows for the first time. During the statistical analysis, it was revealed that the used dataset is insufficient for robust inference regarding the impact of urbanisation on helminth communities due to its temporal and spatial biases. Despite the limitation, the data offer information for future research on the influence of urbanisation on helminth biodiversity in avian hosts.
