For years, biologists have been seeing migratory birds arriving earlier in the spring due to the effects of climate change. But surprisingly, the effect on arrival time is different for members of the same species.

While it’s still unclear what effect this has on bird populations, understanding how climate change can affect females and males differently can help guide our conservation efforts.
