To our knowledge there are no studies concerning UV-B effects on penguins. As their eyes are exposed to a lot of UV due to the high reflectivity of snow and a marked enhancement during the ozone hole, investigation into the impact on penguins is desirable. The fact that penguins are visual predators, eating krill or fish in the water column, would make any eye damage an important issue for survival.

No. This flightless, aquatic bird is native to the Southern Circumpolar Region, only a short 10,000 miles to the south. See similar questions...

Migrating to a new platform has now become a real option for the cutting-edge CIO. It will avoid the risk of an aging system failing at an inopportune moment and the retirement of the only guy who knows how the system truly works! SML is the crucial piece of the migration jigsaw; shining a light into the dark depths of Assembler code and converting it into something useable, in a measurable, iterative process, without having to shut down the system or rebuild it from scratch.(Up) See similar questions...

American Crows can be considered partially migratory. That is, some populations migrate, others are resident, and in others only some of the crows migrate. Crows in the southern parts of their range appear to be resident and not migrate. They may make some changes in their use of space at this time, spending more time off the territory to forage and roost. Crows migrate out of the northern most parts of their range.

No. Penguins, like all other birds, do not have teeth. The chicks do have an egg tooth, but this is not a real tooth, but rather a sharp bump on the top surface of the bill which is used to break the egg when hatching. Penguins do have rearward-pointing, tooth-like barbs on the tongue and roof of the mouth. These are not used for chewing, but instead assist in the swallowing of their slippery prey.

Yes, penguin ears are in the same place as ours. The only difference is that they have no external ear (the fleshy bit that sticks out the side of your head) and that the opening is covered by feathers. See similar questions...

CI: You would have to be fluent in Penguinese to understand the subtle inflections that differentiate their names. To human ears, they are all named "Waark". See similar questions...

For detailed upgrade information, see Section 2.11, "Upgrading MySQL". We recommend that you do not skip a major version when upgrading, but rather complete the process in steps, upgrading from one major version to the next in each step. This may seem more complicated, but it will you save time and trouble - if you encounter problems during the upgrade, their origin will be easier to identify, either by you or - if you have a MySQL Network subscription - by MySQL support.

Because there are seasons. These result in temporary differences in food availability, weather, light conditions, etc. Migratory animals make use of such differences and exploit resources which are available in different parts of the globe only during part of the year or of their life cycles. They have evolved so that they can live for some time in areas that could not sustain them the whole year round. See similar questions...

Most hummingbirds will start their southward migration as early as mid-July, though most will leave between late August and late September. Many people will leave their feeders out through late fall and early winter, as they may have many visitors that will stop by their feeders to refuel before continuing their journey. If you live in an area that stays warm year-round, such as the Southwestern U.S., the hummingbirds may not migrate at all. See similar questions...

Tag and recapture studies have shown that lobsters tagged offshore in the winter and spring have been recaptured inshore in the summer and fall and vice versa (Cooper & Uzmann, 1971, 1980; Fogarty et al., 1980; Campbell et al., 1984; Aiken & Waddy, 1986; Pezzack & Duggan, 1986). Cooper (1977a) estimated that 20-50% of offshore lobsters are migratory. This suggests a pattern of seasonal migration where lobsters move offshore in the winter and spring and inshore in the summer and fall. See similar questions...

No, not all butterflies migrate. Some species can survive the winter as adults, eggs, caterpillars or pupa; thus, do not have to migrate. A major migrant in North America is the Monarch; in Europe and North Africa it is the Painted Lady. It is in the interest of the species to move abroad and find new territories. Getting away from the parental area is good for the species. See similar questions...

When you come to New Zealand, you are entitled to bring your personal effects, household goods, vehicles and boats. Personal effects and household goods may be brought, tax and duty free into the country, up to 4 years from the date of your residence approval. Vehicles must be right-hand drive, and have been owned and used for at least 12 months prior to shipment by the importer. So left-hand drive vehicles can only be imported with the proper approval.

Theories to explain migration involve food, predation, insects, and weather. Migration opens up a larger and more variable food supply. It allows caribou to calve and raise their young away from most wolves that den near the forest-tundra border. It allows them to avoid some of the biting insects and parasites that have an insect stage in their cycle. Finally, it permits them to summer in a relatively cool location and to secure abundant lichens under snow in forested areas in winter. See similar questions...
