Prior-month ozone gave no clear change in survey temperature slopes in four-state bird records in 2005-2019
We tested prior 30-day ozone and survey temperature in 1,366 consecutive-year bird survey pairs from California, Oregon, New York, and Pennsylvania in 2005-2019. We matched route, observer, and ozone site and fit separate region-period models with survey controls and state-year effects. Interaction estimates ranged from -0.132 to +0.297 recorded taxa per 5 C and 10 ppb. All four primary intervals included zero. All 16 sensitivity intervals corrected within each four-test mode included zero. No matched survey had both a start temperature of at least 25 C and a 30-day ozone mean of at least 70 ppb. The test cannot resolve joint extremes. Records overlap earlier campaign studies. Selected coverage, exposure error, seasonal weather, and detection limit inference. The package includes code, source hashes, exposure evidence, model designs, influence checks, and reproduction instructions.
