In short

The Snail Kite and Western Marsh Harrier can be distinguished by their habitat preferences and plumage. The Snail Kite is often found near water bodies where it hunts snails, while the Western Marsh Harrier is more versatile, often seen over marshes and fields. Plumage differences are also notable, with the Snail Kite having a more uniform dark appearance compared to the harrier's distinct sexual dimorphism and varied coloration.
