According to Tim Low (in “Where Song began”), “so easy were they to breed that by 1859 they cost less to buy in London than in Sydney.” ” Funny how the difficulty of breeding a species can be illustrated in simple monetary terms. We even had some chicks – not that this was a big achievement.

According to the HBW, when breeding, male birds do most of the incubation and parenting while females often leave the nest up to one week before the eggs hatch. According to Couzens, after laying the eggs, females sometimes immediately abandon their first mate and pair up with another male. How efficient. How surprising.

Not all of our shorebird species migrate and those that reside here are also currently sitting on eggs, or thinking about laying eggs in the upcoming weeks.

The last example suggests the difficulty of making a clear distinction between an animal part and an animal product. If a genetically engineered animal’s legs periodically fell off, would not its legs be more like a product of an animal (analogous to eggs) than a part of the animal? Would the blood be analogous to milk or eggs?

A few families have a small number of eggs in the clutches, like gulls or cormorants. Others, like the petrels and some of the auks, will lay a single egg per breeding attempt.

That comes at a price – the HBW describes the species as “stocky and fairly sluggish” and – with a critical undertone – continues to state that the species is “generally less agile in flight than are most flycatchers”.

Basically, this species is so dimwitted, it doesn’t know how to survive. Because, Pink Pigeons are not capable of doing the tasks required to create and bring up children of the species.
