    Study of Some Important Aspects of Breeding Ecology and Vocalization of Jungle Prinia in Siswan Community Reserve Punjab India
    (Wildlife Institute of India, Dehradun, 2021) Chandra, Vignesh M.; Mohan, D.; Singh, Pratap
    Several groups of songbirds including North-American wood warblers belonging to the genus Vermivora, Parula, Dendroica, and Setophaga have developed two singing modes or categories of songs which are having different functions. 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.
