<b>Environmental and demographic mechanisms underlying population dynamics provide relative stability in an island songbird</b>

We used an integrated population model to (1) examine ecological drivers of population growth and (2) assess global population trends of the Island Scrub-Jay (<i>Aphelocoma insularis</i>) from 2009-2019. Our results suggest that population size increased slightly over this interval despite declines during severe drought. We also found evidence that density dependence, precipitation, and food availability affected fecundity and the survival of non-breeding individuals.
