Which urban species rebounds fastest

From 3 years of removal records in Richmond, a Leslie matrix with mark–resight inputs pointed to Norway rats returning to pre-cull abundance in about 8 weeks under constant effort, beating pigeons and raccoons in our models. If you’ve run similar projections, did any species outpace rats, and how did that change your deployment schedule?

Your ‘8 weeks’ aligns; starlings rebounded about 6, so we pulsed deployments around hatch peaks… Did constant effort mask seasonality?

House mice rebounded about 5 weeks; we pulsed around trash-day. Did ‘constant effort’ hide waste spikes?

My minimum that sticks is ‘dinner-to-breakfast’ for year one, then 8 h, and I’ll add a bonded 3–3 for any lower with >3 mm pre-tx irregularity; those incisors are escape artists. My TheraMon spot-checks show patients hit about 8–9 h even when told 10–12, so I over-prescribe a bit; @kbrown09 have you seen the same?
