Turdanidae

Turdanidae is a proposed family of passerine birds that includes the jays, magpies, and rooks. This classification is based on genetic and morphological evidence, suggesting a distinct evolutionary lineage for these corvids. The family name is derived from the genus Turdus, although this genus is now placed in the thrush family Turdidae. The members of Turdanidae are known for their intelligence, complex social behaviors, and often omnivorous diets. They are found in a wide variety of habitats across the globe, excluding Antarctica and some oceanic islands.

Key characteristics of birds within the Turdanidae family include strong, stout bills, robust legs, and generally dark plumage, though some species exhibit striking patterns and colors. Their vocalizations are diverse, ranging from harsh calls to more melodic songs. Many species are known for their ability to mimic sounds. Socially, they often form complex hierarchies and exhibit cooperative breeding or feeding behaviors. Their diets typically consist of insects, seeds, fruits, and small vertebrates. Evolutionary studies have placed Turdanidae as a sister group to the Corvidae, a classification that continues to be refined with ongoing research. The exact phylogenetic relationships and the definitive composition of this proposed family are subjects of ongoing scientific investigation.
