This species are long living and so the population appears to be sustainable at this stage despite the predation. The Pied Oystercatchers are actually incredibly predictable when it comes to the dates that they lay eggs, the locations that they choose and the various strategies that each pair use in order to protect their young.

This raises an interesting question: Did these early birds have four wings, or three tails?). When we look at living species (A and B) that we know shared a common ancestor resembling one of them (A), we can guess that the features seen in A evolved in steps more or less linearly to eventually resemble the corresponding features seen in B.

There are sixteen pairs of Pied Oystercatchers and they have varying success at raising young birds. Thankfully with the longevity of this species it appears the population is fairly stable, but this may not always be the case if predation continues at the rate that it is. The last time they successfully raised a chick was in 2012.

The vast majority of the 10,000+ living species of birds are passerines, and the vast majority of those have a similar system of breeding: Mom and dad bird make a nest and share parental responsibilities roughly equally, if not identically. In the latter, three or more adult individuals contribute to the raising of offspring.

Many of the most peculiar aspects of birds are involved with mating, whether it’s for attracting mates, defending nests against predators, or raising chicks. One of the more interesting aspects (in my opinion) of breeding in birds is their mating strategy. of all bird species, is polyandry. 1996, Nakamura 1998).

One of the less well remembered awful things that happened in the Second World War (a six year period of history filled with an uncountable number of awful things) is that war’s direct role in the extinction of two species of rail. The loss of these two species was, in fact, no aberration, except in how late the extinctions were.

The most like strategy of investment by bird parents to evolve is probably both parents caring for the offspring, probably taking turns at the nest, and bringing food back to the chick. In Elk and other deer, to varying degrees and depending on species, males grow antlers that seem to demonstrate their qualities as potential mates.

Note to other species: better do not rely on mature primary forests, as this may lead to extinction. This says more about my inability to differentiate between warbler species than about the rarity of the bird – but the bird was kindly singing. Also, do not smoke as it is not good for your health.
