Beschreibungen/Notizen

• Highlights • We describe two strategies of opportunism: rich patch exploiter and obligate. • Obligate opportunists (OBO) breed in response to unpredictable and rare resource pulses. • Rich patch exploiters (RPE) are highly mobile and move between resource patches. • RPE are predicted to invest more heavily in survival (e.g. HPA sensitivity in crossbills). • OBO are predicted to maintain reproductive readiness (e.g. HPG activity in zebra finch).
