Abstract Global warming is changing habitats and affecting biodiversity, expected to exacerbate aridification in many regions. Animals plants seasonally dry tropical forests often exhibit adaptations cope with seasonal resource limitation. However, whether these will facilitate drought tolerance or increase vulnerability unclear. Here, we combine long‐term individual‐based data on phenology, morphometrics, demographics investigate how impacts the food resources, health, reproduction, behavior of a population Verreaux's sifaka ( Propithecus verreauxi ), critically endangered lemur inhabiting deciduous Madagascar. Between December 2010 May 2023, experienced 3 years severe (2016, 2017, 2022). During green periods drought, availability high‐quality foods (young leaves, fruit) was significantly reduced fruit tree mortality increased. This persisted year after despite typical rainfall. Yet surprisingly, found no negative effects body condition commonly‐used metrics for reproductive success during following drought. Instead, exhibited higher levels subcutaneous fat droughts. We observed little change between non‐drought periods. they were more likely lick dew spent less time feeding young mature leaves. They also increased their flowers fruits, abundance habitat. Together, our results suggest that consumption water‐rich droughts could physiological mechanisms help water scarcity, including fructose‐mediated storage, metabolic production, conservation. These provide new insights into animals may respond climate change, suggesting behavioral limitation buffer some mammals from other extreme weather events.
