How does the Fieldfare (*Turdus pilaris*) reveal a feature in flight that the Redwing lacks?
Answer
It reveals a distinctive pale rump.
When observing a thrush taking flight, the Fieldfare possesses a specific marking that immediately sets it apart from the Redwing: a distinctive pale rump. This light patch on the rear section of the bird becomes apparent in flight, providing an immediate visual cue for identification. The Redwing does not share this pale rump feature. Other distinguishing factors for the Fieldfare include its generally paler, greyish head and nape, and its tendency to forage more aggressively in larger, cohesive groups compared to the generally more reserved movements of Redwings near a large contingent.
