Marcus and Will delve into the implications of declining insect populations on ground-nesting birds like wild turkeys. They discuss the impact of insect decline on wildlife, challenges in interpreting studies, the relationship between insect decline and bird species, and the benefits of habitat enhancement techniques for preserving bird populations in changing landscapes.
Planting wildflower strips with diverse forb mixtures can enhance bird species richness and density.
Insect declines are impacting bird populations, emphasizing the importance of diverse plant communities for habitat.

Insect Declines Impacting Birds
Studies suggest that insect declines are having a significant impact on bird populations, particularly ground-breeding farmland birds. The decline of insectivorous birds has been greater than non-insectivorous birds, leading to concerns about the availability of suitable nesting sites and food sources. Habitat management practices like planting wildflower strips have shown to provide beneficial nesting sites and increased food availability for birds, indicating the profound link between insects, habitat, and bird populations.
Wildflower Strips and Bird Diversity
Research shows that establishing wildflower strips with diverse forb mixtures in agricultural fields can significantly enhance bird species richness and density compared to controls without wildflower strips. The presence of forb-rich vegetation in such strips acts as a primary driver promoting bird diversity and abundance, emphasizing the importance of diverse plant communities and habitat structures for bird populations.
Importance of Habitat and Insect Abundance
Evidence suggests that the availability of insects, facilitated by diverse plant communities and suitable habitat structures, plays a crucial role in supporting bird populations. Practices like planting wildflower strips or managing habitats to enhance diversity and abundance of insects have shown to positively impact bird species richness and productivity, reinforcing the vital connection between habitat quality, insect abundance, and bird populations.
Cicada Hatches and Wildlife Populations
Upcoming cicada hatch events present an opportunity to study the relationship between insect abundance and wildlife populations, particularly turkeys. Observing the potential increase in turkey reproduction linked to cicada abundance could provide valuable insights into how insects serve as a limiting factor for bird populations and the importance of habitat management practices in sustaining wildlife populations.
Marcus and Will sit down under one roof to review the available literature on declining insect populations. They pull from studies across the globe to discuss the implications of insect declines on terrestrial, ground-nesting birds and how we can help mitigate these effects for the wild turkey.
