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.

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.

One scientists posits that harvesting of horseshoe crabs (their eggs are a preferred Red Knot food source) at a crucial refueling stop on the birds’ migration could be part of the problem.

We noticed a strategy being used by the Little Terns that we have observed before with Pied Oystercatchers and Black-fronted Dotterels. We could see there was a marker we could use to go by the nest from a distance and establish if they were cooling eggs or chicks. The Little Terns had actually placed the two eggs near a small stick.

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.

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.
