These displays exhibit the complex head markings, as well as the body, tail, and wing patterns found in most species.
With complex dark markings that can take on the appearance of vines, lacy twigs or swiftly moving amoebalike shapes, Hisako Kobayashi's work comes closest to suggesting aspects of nature.
The conventional wisdom is that recognizable eggs must have three visual qualities: They should be highly similar to eggs holding their siblings; distinct from eggs laid by other mothers of the same species; and have complex, dense markings to make them more difficult to mimic.
Scientists assumed that multiple genes are responsible for these complex colors and markings.
The scientists also found that complex, dense egg markings could actually make it more difficult for mother birds to recognize their eggs.
These animals are well-known for their ability to vary their color pattern and skin texture, producing patterns so complex that individual markings have hitherto been considered difficult or impossible to distinguish.
When observed at ultraviolet wavelengths, the clouds exhibit distinctive dark markings, with complex swirling patterns near the equator and global-scale bright and dark bands that are V-shaped and open toward the west.
Among the more powerful images in this small selection of oils and works on paper are "Head" (1939), a skull-like presence whose complex black-on-white linear markings seem a synthesis of African and American Indian art (Grace Glueck).
According to a NASA news release, it is theorized that Pluto's atmosphere of nitrogen, complex seasons, and distinct surface markings and an ice-rock interior may harbor an ocean.
The species complex shows considerable variation in wing markings, voltinism, flight periods, host use, and oviposition behavior [ 37].
