In the Cuculus Americanum are eggs small, if so wd show fact incidental as our Cuckoo

Does Molothrus pecoris eject young?

Ch 10

[Natural selection, pp. 506-7: "But ever since classical days, the instinct which leads the/80/Cuckoo to lay its eggs in other birds' nests, has excited much surprise. Some species of the group, always build their own nests & hatch their own eggs. This is generally the case with the Cuculus Americanus, but sometimes this species lays its eggs in other birds nests;1 & even our own Cuckoo (C. canorus) has not absolutely lost its aboriginal (according to our theory) instinct of nidification & incubation, as it certainly has been known to rear its young.
