The use of eBird data is interesting and it shows just how valuable the collected reports of birders can be in figuring out the status and distribution of species. Just as interesting is the nugget that Pin-tailed Whydah , an introduced species itself, has adapted to using Nutmeg Mannikins as a host for its eggs.

The early threats of guano harvesting and egg collecting have been replaced by the more ominous threats of oil pollution and overfishing of their favorite food source – pilchards. On the mainland they face predation from domestic cats, dogs, genets, mongoose and Cape Gulls which steal their chicks and eggs.

We continue to have egg predation at many of the nest sites and chick loss, but one pair of Pied Oystercatchers is being successful in raising two chicks so far. There has never been two eggs hatch and two chicks survive for more than about ten days since we started to keep an eye on them in 2000.

This laughingthrush is a cooperative breeder – nestlings are fed by all members of a group, often 6-12 (not just 2 as in Wham!): “A female may share a nest with another, and 3 or more adults may take turns incubating the eggs and feeding the chicks.” ” ( source ).

Egg harvesting to sell as food was intensive then, with thousands taken annually from the breeding colonies in Chile. Egg collection for local consumption still continues at lower scale. The initial decline in the Andean Flamingo’s population appears to have started as early as the mid 20th Century.

Last year not a single chick survived and there is much predation of both eggs and young birds along the length of beach. The first pair of Pied Oystercatchers to lay eggs this year was the same as last year. The first egg laid is not necessarily the first to hatch and often there is a day in between when they hatch.

It is listed as vulnerable, though its rather rigorous treatment of the second, smaller chick in a clutch (it starves to death within 1 week, rarely a month, according to the HBW) offers the potential for collecting second-hatched chicks for reintroduction programs. They are not much into flying. Is it boredom or depression, or both?

After mating, a single egg is laid and incubation duties are shared by both parents. The egg can stand a fair degree of chilling, so a single parent can afford to leave the burrow for sometime to feed without losing the egg if its partner does not return quickly. While one bird sits, its mate feeds out at sea for a week or so.

If we had been predators, their actions would have (hopefully) led us away from the nest, keeping their eggs and chicks safe. Next to it lay an egg, the baby inside fervently pecking and tapping until it too could break the shell and emerge onto the dunes. While not as adorable as chicks, I still love to see bird eggs!

Speaking of pregnant snakes, do sea snakes lay their eggs ashore like sea turtles or do they keep them internally until the young are ready to hatch/ be born, like some sharks? These do lay eggs on land and are (reasonably) mobile once they hit the beach. It seems like there is great diversity in this continent.
