Vanessa cardui painted lady's migration pattern in northern Europe apparently does not follow a strict northwest heading. The range of headings suggests that migrating butterflies may adjust their migration patterns in response to local topographical features and weather, such as strong wind patterns. Laboratory-raised autumn-generation painted lady butterflies were able to distinguish a southern orientation for a return migration path. According to the same laboratory-based study, when butterflies were isolated from the sun, they were unable to orient themselves in a specific direction, opposed to those that did have access to the sun. This suggests that "V. cardui" requires a direct view
Black-and-orange flycatcher insects an hour whereas at mid-day they are half as efficient. The black-and-orange flycatcher along with the rufous-chested flycatcher ("Ficedula dumetoria") are the only sedentary species within the genus "Ficedula" and lack the longer and more pointed wing morphology of the long distant migrant members. 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
