Estimating the Impact of Airport Wildlife Hazards Management on Realized Wildlife Strike Risk

November 2024

Wildlife hazards management programs improve wildlife strike reporting and reduced strike-induced economic damages, demonstrating a significant cost-benefit ratio and highlighting the complexities of measuring and mitigating wildlife strike risk.

The Impact of the COVID-19 pandemic on wildlife-aircraft collisions at US airports

July 2023

The dramatic reduction in air traffic during the COVID-19 pandemic led to a counterintuitive increase in wildlife strike rates at major US airports, likely due to increased wildlife activity and abundance in the quieter airport environments.

Spillover Delay Effects of Damaging Wildlife Strike Events at US Airports

June 2022

Damaging wildlife-aircraft collisions with commercial aircraft generate substantial delays in the 24-hour post-incident period, a disruption that is largely contained within the airline to which the strike occurred.

The Longevity-Frailty Hypothesis: Evidence from COVID-19 Death Rates in Europe

February 2022

Variations in pre-existing health frailty, shaped by differing long-term survival environments across Europe, significantly contributed to the uneven distribution of COVID-19 death rates during the pandemic’s first wave.

Estimating Wildlife Strike Costs at US Airports: A Machine Learning Approach

August 2021

Machine learning methods improve the accuracy of wildlife-aircraft collision cost estimations for US civil aviation by both factoring in specific strike characteristics and reducing the influence of rare, high-cost outliers.

Toxic Baits as a Strategy for Controlling Invasive Wild Pigs: Acceptability Among Crop Producers

March 2025

A majority of crop producers find toxic bait use acceptable for wild pig management, with acceptance higher among larger operations and those growing vulnerable crops, but lower among those profiting from wild pig hunting.
