主 题：blood parasite male quality morphology red junglefowl Gallus gallus vocalization
摘 要：Bird songs are considered a sexually selected trait that can reflect the individual health of males as well as the vitality of potential mates and their *** features should,therefore,be related to parasite load and body ***,we performed a thorough acoustic analysis of the display calls of 9-month-old sub-adults and 18-month-old adults of pasture-raised red junglefowls Gallus *** investigated whether the calls of pasture-raised red junglefowls can indicate body size and body condition,in addition to the influence of parasitic infection intensity on the expression of sexual *** found that frequency-related syllable parameters were significantly positively correlated with wing length in adults,whereas body weight was independent of both the frequency and temporal parameters of *** addition,we correlated parasitic load with the expression of sexually selected traits and discovered a positive association between the intensity of parasite infection and wing length in sub-adults,independent of vocal ***,the results suggest that the vocalization of red junglefowls may convey reliable body size information,which will facilitate further studies of different vocal parameters in the transmission of bird vocalizations.
