I would never have believed it, but if the science says so who am I to argue otherwise? But it seems sort of appropriate in hindsight that a family so strange would end up alongside a similarly unpredictable group of birds in the flamingos. But that’s a group for a different time.

Seabirds are one group of birds that go for the latter strategy. Others, like the petrels and some of the auks, will lay a single egg per breeding attempt. The investment placed in each clutch bur seabirds is so great that only one breeding attempt can be seen to completion each year.

The first shorebird arrivals are apparently birds that failed at a breeding attempt and don’t have time to re-attempt; they might as well head south early. This is by no means an exact science.
