Quick Answer
To track mergansers during migration seasons, locate them near fish-rich waters, and use a spotting scope to identify their habitat and behavior. Mergansers are often found in areas with abundant fish populations, such as rivers, lakes, and estuaries. Employing a guide familiar with local waterways can also enhance your tracking efforts.
Habitat Identification
When tracking mergansers, focus on areas with dense aquatic vegetation, such as submerged aquatic plants and shoreline vegetation. This vegetation provides mergansers with shelter and ambush points for hunting fish. Identify bodies of water with a mix of sand, gravel, and rock substrates, as these areas tend to hold more fish. Note that mergansers often prefer areas with a mix of fast and slow-moving water.
Waterfowl Behavior and Sign
Mergansers are social birds that typically travel in small groups. Observe their behavior, looking for signs of fish feeding activity, such as splashing, chirping, or the presence of diving birds. Check for merganser sign, including preening fish remains, droppings, and feathers, which can indicate their presence. Be aware that mergansers are opportunistic feeders and may shift to different areas in response to changing fish populations.
Advanced Tracking Techniques
Employ a spotting scope to scan the water and surrounding habitat from a distance. This allows you to identify merganser behavior, body language, and habitat use patterns. Use a range finder to estimate distances to the birds and determine the best vantage points for a hunt. Consider partnering with a local guide or experienced waterfowler who can share knowledge of local habitats, water levels, and merganser behavior.
