Abstract
The results of a microspectrophotometric and a behavioural test presen t evidence that the passeriform bird Leiothrix lutea (Timaliidae) poss esses a genuine UV cone type and is highly sensitive in the UV part of the spectrum. Those data are in accordance with results of other test s indicating that a majority of bird species is UV sensitive (either b y a UV cone type or somewhat limited by a violet cone typ). Possible u se of this extended sensitivity like orientation according to the pola risation pattern of the sky, species and/or mate recognition and food detection are discussed.
