The first eggs were laid in the first week of July, which is the case each year. The eggs take 28 days to hatch and it is then at least 35 days before the chicks are developed enough to fly and there have been problems with predation as in other years.

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!

But the honeyguides, indigobirds, and a single species of duck all do the classic cuckoo strategy (obligate interspecific brood parasitism) as well. This behavior is most common in colony nesters, since popping next door to drop off an egg is a lot easier than hunting down another nest through acres of forest or grassland. But come on.

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.

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.

Fortunately for them (though less so for the cuckoo), in one experiment they ejected 100% of all cuckoo model eggs. A relative of them, the Brown-breasted Bulbul, relies on a different strategy to avoid being cuckolded – placing their nests away from forests (where the cuckoo lives), and aggressively attacking cuckoos.

Since I found the first Pied Oystercatcher nest on Cable Beach in July 2000 I have learnt that the eggs rarely hatch due to predation and if they do hatch then a fully fledged chick is a rare and wonderful outcome. This year has been like other years with the first eggs being laid late June and the first chicks hatching recently.

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. The result of this cooperative breeding strategy is that fledging success increases with group size and survivorship is also significantly higher for all birds living in these larger groups 1.

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.

One of the more interesting aspects (in my opinion) of breeding in birds is their mating strategy. There are four main mating strategies in birds: 1) monogamy, 2) polygyny, 3) polyandry, and 4) polygynandry. The final, rarest mating strategy, found in less than 0.1% of all bird species, is polyandry.
