Abstract: 

Calls of the Indian jungle crow as well as the Indian house crow have been recorded at some typical urban habitats in Bangalore city. Calls of the jungle crow were also recorded at the field station of Indian Institute of Science at Mudumalai National Park in Tamilnadu, India. Spectrograms of the calls were obtained and analyzed with Raven-Pro software. Between the two species of crows found in Bangalore city, house crows are found to be more capable than the jungle crow in producing vocalizations with wide spectrum and higher frequency components (15 kHz to 18 kHz or even more). Jungle crows on the other hand, are found to be more competent with regards to producing vocalizations with significant low frequency components (400 Hz to 800 Hz). A comparison between the calls of jungle crow at Mudumalai field station of IISC and those at urban habitat sites in Bangalore city reveals that jungle crows tend to produce vocalizations at higher frequencies in urban situations though they are not able to match the performance of house crows in this regard.
