The “Owls and Albatrosses” chapter, for example, begins with Doug’s personal experiences observing of the nesting strategies of Malleefowl and a Moluccan Megapode, Australasian “chickens who lay their eggs in unusual ways and do not parent. ” (p. And then we go back to the evolution of clutch size.

At mid-life crisis, the mother, Lili, decides to leave her husband (Gabe’s father) and return to take up farming on her family estancia in eastern Uruguay, far from the delights of Montevideo where most of her rambunctious, rollicking family resides, overseen, not always approvingly, by Gabe’s quirky abuela.

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.

Besides the avian attributes of flight, feathers and laying eggs, potoos are quite possibly the most unbird-like birds in the world. Sometimes called “Poor-me-ones&# on account of their haunting calls, these bizarre denizens of the night come in 7 different flavors from the family Nyctibiidae within the order Caprimulgiformes.

The first eggs are laid during the first week of July each year and if these eggs fail to hatch or the chicks are lost they will lay further eggs within a few weeks. Sadly a lot of eggs are lost to feral cats and chicks are sometimes taken by birds of prey. Nest site with 3 eggs-one white!

Ackerman surrounds each individual story with background facts and studies on other birds who mimic, play, parasitize nests, engage in complex cognitive routines, parent in unusual ways–presenting a complex mosaic of avian behaviors amongst bird families and the scientific histories of trying to understand them.

Most Acorn Woodpeckers are cooperative breeders and live in family groups of up to a dozen or more individuals. 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. This is their range map courtesy of Nature Serve.

They are two strikingly different strategies, both of which seem to working well this spring, as everywhere one turns there is new life on the Tundra. I had hoped to have some Semipalmated Plover chick photos for comparison but as of last night they seem to be still at the egg stage. With some serious legs.

While having somebody else raise your chicks like an attractive strategy to me, it is not without dangers. Not only does this species directly parasitize other species but also metaphorically, by imitating the sparrowhawks in its appearance and thus deterring potential predators.

The one bird I did not see here, however, was the Bateleur Eagle … One highlight in the area is the Saddle-billed Stork , likely to be the tallest species in the stork family. Another member of the stork family, the African Openbill , looks like it is could benefit from a good orthodontist. And sadly, it is listed as Endangered.

In China, wherever there is one real tourist attraction (like the Great Wall), the local strategy seems to be to add some fake attractions – replicas of palaces or tombs, amusement parks, shopping centers – in order to maximize the income from tourists. But the starting point has to be a real attraction, not a fake one.

But, unlike most books focused on a bird family, this one is organized geographically. For New Zealand, he describes each of the Subantarctic Islands and mainland islands and beaches where its nine Penguin species are found, including endemic species like Snares, Erect-crested, and Royal, and suggests strategies for seeing them all.

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.

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.

In other words, you can’t say something like, “humans, gorillas, chimps, and bonobos are all in the same family and equally related to each other.” That was probably a great strategy for rapid reproduction … live very fast and die very young.

This may have been partly a leftover from the Victorian fascination with egg collecting (the infamous passion known as oology), but probably more from people’s burgeoning interest in the nests and eggs found in their gardens and fields, gateway artifacts to a newer hobby called birdwatching.

I have written about the interesting sex life of these jacanas a few times already (short version: female mates with male, lays a bunch of eggs for him to incubate and raise the chicks, leaves him, finds another male, repeat). Apparently, after a male first mates with a female, he throws out the first one or two eggs she lays in their nest.
