Vanessa cardui of the sky, implying the use of a solar compass to orient its migratory direction and maintain a straight flight path.

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
