The local Bald Eagles are getting busy, I suspect there is an egg in the nest. The Izu scincid lizards (Plestiodon latiscutatus) that inhabit the four Japanese Izu Islands with only bird predators are drab brown, mature later, lay small clutches of large eggs, and hatch large neonates. All I see are their buts.

There are two patterns that are fairly extreme that fall into this category: brood parasitism and helper-at-the-nest strategy. In the former, a female lays her fertilized egg in the nest of another species, in the hopes that her offspring will be raised by the unwitting hosts. It turns out that the two strategies may be related.

Both Elk and songbirds have the same basic method of inseminating eggs, which is one of the steps in reproduction (but not by any means the first!), Songbirds grow the offspring internally for only a very short while, and then pop out an egg, which is then cared for over a significant period of time until it hatches.

Within the bird world, so many different strategies and methods of mating and reproduction have evolved, it simply boggles the mind. There is some debate on the reproductive/genetic benefits of this, although a common view is that individuals don’t want all their eggs in one genetic basket, so to speak (pun intended, zing!).

And the nandu, a South American rhea, has an intriguing chick-survival strategy: a week before hatching, the male (who does the incubating) pushes one egg out of the nest. They fly at night and end up in places you wouldn’t expect them.”. It breaks, attracting flies, which result in maggots that eventually feed the other chicks.
