How to prevent overpopulation of undesirable species in dove fields?

Habitat Selection and Modification

When selecting crops for a dove field, choose species that attract the desired game species and repel or are less attractive to undesirable species. For example, sunflowers (Helianthus annuus) are highly attractive to mourning doves (Zenaida macroura) and white-winged doves (Zenaida asiatica) but less attractive to invasive species like European starlings (Sturnus vulgaris). By modifying the habitat to favor the desired species, landowners can reduce the presence of unwanted species.

Hunting Pressure and Strategies

Strategic hunting pressure can be an effective tool for managing undesirable species. For example, early-season hunting for mourning doves can help reduce populations before they become established, making the field less attractive to invasive species. Additionally, using bird-deterrent hunting techniques, such as spot-and-stalk hunting or using decoys, can help reduce the effectiveness of hunting for undesirable species. This can help maintain a balance between game species and non-game species.

Integrated Pest Management (IPM) Techniques

Implementing IPM techniques can help control undesirable species in dove fields. This can include using bird-repellent plants, such as daffodils (Narcissus pseudonarcissus) or amaranth (Amaranthus retroflexus), or using noise-making devices, like propane cannons, to scare away undesirable species. Another effective technique is using bird-control nets or bird-scaring balloons to create a physical barrier or visual deterrent. By combining these techniques with habitat modification and hunting pressure, landowners can effectively manage the population of undesirable species in dove fields.
