Shadows in Bird Land

Shadows in Bird Land

Trout are easily spooked by shadows moving overhead, but the stationary shadow is often an umbrella where they find comfort and calm, especially on bright, sunny days. 

The moving shadow above can trigger an instinctively defensive reaction; fish think it might be a predator. The stable shadow, one cast from an overhanging tree or a cut bank, gives the trout protection from such predators.

If you happen to walk up on a pool and spot some small trout, raise your arms or rod to create a shadow, and move the shadow above the fish. You'll see exactly what we’re talking about: The fish will flee for cover almost instantly.

In the context of reading water, it’s important to factor in the presence of shadows. The wind-blown tree branch that’s waving back and forth above the river surface is not a good trout magnet. On the other hand, that tall rocky wall or stand of thick willows casting a shadow over the river is a good place to direct your attention.

Look for structure and current breaks in shadows when planning a cast. Absent these, cast near the dark-to-light shadow transition, usually a foot or two to the dark side.

Remember: stable shadows good, moving shadows bad.
