Here is a question about this article: Brood parasitism, in which an egg-layer leaves her eggs with another individual's brood, is more common among birds than any other type of organism. After a parasitic bird lays her eggs in another bird's nest, they are often accepted and raised by the host at the expense of the host's own brood. Brood parasites may be either obligate brood parasites, which must lay their eggs in the nests of other species because they are incapable of raising their own young, or non-obligate brood parasites, which sometimes lay eggs in the nests of conspecifics to increase their reproductive output even though they could have raised their own young. One hundred bird species, including honeyguides, icterids, and ducks, are obligate parasites, though the most famous are the cuckoos. Some brood parasites are adapted to hatch before their host's young, which allows them to destroy the host's eggs by pushing them out of the nest or to kill the host's chicks; this ensures that all food brought to the nest will be fed to the parasitic chicks.
What is the answer to this question: What type of birds lay eggs in the nests of conspecifics to increase their reproductive output?
****
So... non-obligate brood parasites


Here is a question about this article: The Desert National Park in Jaisalmer is spread over an area of 3,162 square kilometres (1,221 sq mi), is an excellent example of the ecosystem of the Thar Desert and its diverse fauna. Seashells and massive fossilised tree trunks in this park record the geological history of the desert. The region is a haven for migratory and resident birds of the desert. One can see many eagles, harriers, falcons, buzzards, kestrels and vultures. Short-toed eagles (Circaetus gallicus), tawny eagles (Aquila rapax), spotted eagles (Aquila clanga), laggar falcons (Falco jugger) and kestrels are the commonest of these.
What is the answer to this question: What are the most common types of eagles one might see in the Jaisalmer region?
****
So... Short-toed eagles (Circaetus gallicus), tawny eagles (Aquila rapax), spotted eagles (Aquila clanga)


Here is a question about this article: One of the uses for scales that assess sexual orientation is determining what the prevalence of different sexual orientations are within a population. Depending on subject's age, culture and sex, the prevalence rates of homosexuality vary depending on which component of sexual orientation is being assessed: sexual attraction, sexual behavior, or sexual identity. Assessing sexual attraction will yield the greatest prevalence of homosexuality in a population whereby the proportion of individuals indicating they are same sex attracted is two to three times greater than the proportion reporting same sex behavior or identify as gay, lesbian, or bisexual. Furthermore, reports of same sex behavior usually exceed those of gay, lesbian, or bisexual identification. The following chart demonstrates how widely the prevalence of homosexuality can vary depending on what age, location and component of sexual orientation is being assessed:
What is the answer to this question: What will cause the amount of homosexuality to vary?

So...
which component of sexual orientation is being assessed
