Rather than read the back of the cereal box, I am currently reading articles on bird behavior, including “Parental cooperation in a changing climate: fluctuating environments predict shifts in care division.”
Cooperation among birds has been shown to increase the chances of successfully raising offspring. Sometimes this means taking turns sitting on the nest and incubating the eggs. In plovers, the females do more of the incubating and typically take the day shift, while the males sit on the eggs at night. As temperatures rise, it becomes more difficult for the females to sit during the day. This study examined populations at different temperatures.
