Vanessa cardui migrations take place at high altitude, which explains why these migrations are seldom witnessed. "V. cardui" is known for its distinct migratory behavior. In California, they are usually seen flying from north to northwest. These migrations appear to be partially initiated by heavy winter rains in the desert where rainfall controls the growth of larval food plants. Painted lady migration patterns are highly erratic and they do not migrate every year. Some evidence suggests that global climatic events, such as el Niño, may affect the migratory behavior of the painted lady butterflies, causing large-scale migrations. Based on experimental data, the
Black-and-orange flycatcher Black-and-orange flycatcher The black-and-orange flycatcher or black-and-rufous flycatcher ("Ficedula nigrorufa") is a species of flycatcher endemic to the central and southern Western Ghats, the Nilgiris and Palni hill ranges in southern India. It is unique among the "Ficedula" flycatchers in having rufous coloration on its back and prior to molecular studies was suggested to be related to the chats and thrushes. A distinctly coloured bird found mainly in the high-elevation areas of the Western Ghats, the Nilgiris, the Palnis and associated hill ranges. The male is distinctly black headed with black wings. The female has the black replaced by dark
