Dunlin and Pectoral Sandpiper chick growth indices (see text for definition) relative to invertebrate biomass from top‐ranked linear mixed‐effects models (see Table 3) near Utqiaġvik, Alaska, 2013–2016. For Dunlin, we illustrate the effect of seasonal hatch date (present as an additive effect in the top‐ranked model along with invertebrate biomass) at three levels representing the minimum (dot‐dashed), average (solid), and maximum (dashed) values during the 2–10 day posthatch period. The horizontal dotted line in each graph indicates average growth; vertical dotted line represents the amount food needed for average chick growth (see text)
