Studies on improving ostrich egg hatchability. Also, I learned that in the US , ostrich eggs are priced at $40-$75. Each fresh egg weighs 4 pounds and is the equivalent of 24 chicken eggs. . Each of these ‘families’ consists of a single mating pair and 1-5 ‘helpers’ who assist in raising the young.

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.

All three species mentioned in this article breed on these islands, but the Piratic Flycatcher employs a truly piratic strategy: the breeding pair targets a recently built woven nest, often by a Yellow Oriole or Yellow-rumped Cacique but they have also been recorded targeting the nests of other flycatchers.

A nest wasn’t found until 1903, which set off a craze for Kirtland’s Warbler skins, nests, and eggs. The good included the development of a new, more open, conservation strategy that embraced communication and education of the community. It was the end of prescribed burns as part of the Kirtland’s Warbler recovery plan.

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.

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.

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. The final, rarest mating strategy, found in less than 0.1%

Within the bird world, so many different strategies and methods of mating and reproduction have evolved, it simply boggles the mind. Male and female Yellow-rumps pair up on their breeding grounds, share duties in raising chicks, then politely part ways when fall migration comes.

Both Elk and songbirds have the same basic method of inseminating eggs, which is one of the steps in reproduction (but not by any means the first!), Songbirds grow the offspring internally for only a very short while, and then pop out an egg, which is then cared for over a significant period of time until it hatches.

Her narrator is Gabriel, 23, raised in Northern California by an American father and a Uruguayan mother. And the nandu, a South American rhea, has an intriguing chick-survival strategy: a week before hatching, the male (who does the incubating) pushes one egg out of the nest.

For the authors of this study on the Sabota Lark , this makes them end the abstract of their paper with the slightly pompous and simultaneously slightly unambitious claim that “This study provided a foundation for future comparative studies on avian life-history strategies in larks.” She also laid eggs in Melba Finch nests.

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). Once I am moderately successful, I often find such photos quite pleasing. but they do. See the sequence below.
