Two ozone sites gave no clear repeated temperature interaction in four-state bird richness records in 2005-2019
We tested whether choosing one of two nearby ozone sites changes the ozone by survey-temperature slope in recorded bird richness. We used the same 1,599 four-state survey records and the same exposure dates in 2005-2019. Eight site-specific slopes and four paired differences had family intervals that included zero. Monitor choice reversed two point-estimate signs, but no paired difference was clear. The data did not establish a repeated negative interaction or equivalent site slopes. Selected routes, missing days, shared sites, small samples and detection limit inference. Survey temperature is not long-term climate. The package gives common-day evidence, full designs, code, source hashes and offline checks.

Prior interaction test used same-site annual pairs. This study tests a paired site-choice contrast on identical records, with overlapping source observations.
