Yep. It certainly looks the other way when prominent members of it espouse abortion and homosexual "marriage."
About 56 of the Old World species and 3 of the New World species (Pheasant, Pavonine, and Striped) are brood parasites, laying their eggs in the nests of other birds.[14] These species are obligate brood parasites, meaning that they only reproduce in this fashion. In addition to the above noted species, yet others sometimes engage in non-obligate brood parasitism, laying their eggs in the nests of members of their own species in addition to raising their own young. The best-known example is the European Common Cuckoo. The shells of the eggs of brood-parasites are usually thick.[16] They have two distinct layers with an outer chalky layer that is believed to provide resistance to cracking when the eggs are dropped in the host nest.[17] The cuckoo egg hatches earlier than the host's, and the cuckoo chick grows faster; in most cases the chick evicts the eggs or young of the host species. The chick has no time to learn this behavior, so it must be an instinct passed on genetically. The chick encourages the host to keep pace with its high growth rate with its rapid begging call[18] and the chick's open mouth which serves as a sign stimulus.[19] Cuckoos have evolved various strategies for getting their egg into a host nest. Different species use different strategies based on host defensive strategies. Female cuckoos have evolved secretive and fast laying behaviors, but in some cases, males have been shown to lure host adults away from their nests so that the female can lay her egg in the nest.[20] Some host species may try to directly prevent cuckoos laying eggs in their nest in the first place – birds whose nests are at high risk of cuckoo-contamination are known to mob cuckoos to drive them out of the area.[21] Parasitic cuckoos are grouped into gentes, with each gens specializing in a particular host. There is some evidence that the gentes are genetically different from one another.
And the cuckoos have been laying eggs in the Catholic Church for hundreds of years. But when Pope John XXIII opened the windows, thousands of more cuckoos flew in to open arms at St Peter's.
