At mid-life crisis, the mother, Lili, decides to leave her husband (Gabe’s father) and return to take up farming on her family estancia in eastern Uruguay, far from the delights of Montevideo where most of her rambunctious, rollicking family resides, overseen, not always approvingly, by Gabe’s quirky abuela.

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.

There is egg predation, chick loss and sometimes possibly just some “bad parenting”! One pair of Pied Oystercatchers laid eggs the first year and did not appear to realise they were supposed to sit on them, but they have since learnt it is an essential part of rearing a chick and they have done so since.

In China, wherever there is one real tourist attraction (like the Great Wall), the local strategy seems to be to add some fake attractions – replicas of palaces or tombs, amusement parks, shopping centers – in order to maximize the income from tourists. But the starting point has to be a real attraction, not a fake one.

The first eggs are laid during the first week of July each year and if these eggs fail to hatch or the chicks are lost they will lay further eggs within a few weeks. Sadly a lot of eggs are lost to feral cats and chicks are sometimes taken by birds of prey. Nest site with 3 eggs-one white!

Starvation and predators make it hard to grow up, and birds have evolved a lot of strategies to give (at least some of) their chicks the best chance in life. One strategy that varies among birds (and other animals) is the number of offspring. Seabirds are one group of birds that go for the latter strategy.

I have written about the interesting sex life of these jacanas a few times already (short version: female mates with male, lays a bunch of eggs for him to incubate and raise the chicks, leaves him, finds another male, repeat). Apparently, after a male first mates with a female, he throws out the first one or two eggs she lays in their nest.

Most Acorn Woodpeckers are cooperative breeders and live in family groups of up to a dozen or more individuals. Within a group, 1–7 male co-breeders compete for matings with 1–3 joint-nesting females who lay their eggs in the same nest cavity. This is their range map courtesy of Nature Serve.
