Among Indian breeding birds Jungle Prinia along with three Phylloscopus warblers (humei, pulcher, and chloronotus) are known to have two singing modes. To find out function of two singing modes by the bird during different stages of breeding in Jungle Prinia, I studied the use of two singing modes of Jungle Prinia and its relation with its habitat or vegetation. My study suggests that the singing mode A is related to aggressive mal-male interactions and singing mode B is linger distance signal and has role in male and female interactions. Bird density was found to be positively related to the differential singing mode B use.enSongbirdsBirdsBreeding ecologyVocalizationJungle PriniaSiswan communityPunjabThesis
