A field researcher observes that a species of bird in the Amazon has its nesting success rate drop from 70% to 55% due to rising temperatures. If 200 nests are monitored, how many more nest failures occur in the second year compared to the first? - Parker Core Knowledge

How Rising Temperatures Are Changing Bird Nesting in the Amazon – Why 200 Nests Matter for Amazonian Ecosystems and Climate Research
In regions where climate shifts are accelerating, researchers are uncovering surprising changes in wildlife behavior—none more striking than the decline in bird nesting success in remote Amazonian forests. A field researcher observes that a native bird species’ nesting success rate has dropped sharply, from 70% in recent baseline surveys to 55% in the past two years, a 15-percentage-point decline driven largely by rising temperatures. With over 200 nests now under continuous monitoring, scientists are calculating the real impact: how many more failed nests occur now—and what this means for rainforest resilience and broader environmental trends.
This shift reflects a deeper effort to understand how climate change disrupts delicate ecological balances. As global temperatures continue to rise, species finely tuned to specific environmental cues face new pressures. In this study, temperature extremes and shifting rainfall patterns appear to interfere with critical nesting behaviors, reducing survival rates for vulnerable chicks. With 200 nests observed, the data reveals a measurable increase in nest failure—a quantifiable signal of climate stress in one of Earth’s most biodiverse regions.
