Hatching of cuckoo eggs

Description

Cuckoos place their eggs in other birds' nests for hatching and rearing. Researchers investigated 154 cuckoo eggs and measured their size. The adoptive species is also registered (three types). It is believed that cuckoos choose the “adoptive parents” such that the cuckoo eggs are similar in size to the eggs of the adoptive species.
