Marsh Widowbird vs Buff-shouldered Widowbird

In short

The Marsh Widowbird and Buff-shouldered Widowbird are similar in appearance but can be distinguished by the color of their shoulder patches and tail length. The Marsh Widowbird typically has darker, more subdued shoulder patches compared to the Buff-shouldered Widowbird's brighter buff patches. Observing tail length and behavior during breeding displays can also aid in identification.
