How do cicadas survive at temperatures up to +46 °C? Do hummingbirds know when they take off across the Gulf of Mexico that they will be flying for about 17 hours without landing? Why do the branches of some trees stop lengthening by mid-June, although there are still almost three months of summer ahead, but the vines and shoots on the stumps continue to grow intensively? The famous American naturalist Bernd Heinrich describes the complex mechanisms of interaction of animals and plants with the environment and various strategies of their behavior in the summer. The author focuses on frogs, woodpeckers and woodpeckers, wasps, blueberry and cecropia butterflies, woodcutter beetles, dipterous insects, ants and other representatives of the animal kingdom, as well as plants, mosses and lichens. Beautifully illustrated with the author's drawings and filled with his inexhaustible love for nature, the book covers the peculiarities of the behavior of animals and plants in summer conditions, which in some aspects are no less complex than winter conditions.
