Acoustic communication of passerine birds of Anaikatty hills with special emphasis on Common Iora Aegithina tiphia
(SACON, 2019) Divyapriya, C; Pramod, P
Bird acoustic communication is intended for species identification between groups (interspecific communication) and for individual identity within a group (intraspecific communication (Simmons, 2002). Bird vocal signals comprise a mixture of tones (harmonic sounds) such as chirps, clicks, less harmonic mumbles, wheezy chats, rattles and buzzy noises. Male birds use complex songs for territorial establishment and maintenance (Catchpole & Slater, 2008; Bhatt et al., 2000; Marler, 2004); and mate attraction (Marler, 2004). Songs have various other functions, for; (i) distracting potential predators (Ritchison, 1991); (ii) informing the mates about the threat (Kermott, & Johnson, 1991); and (iii) coordinating nest exchanges between mates
Resource utilization patterns of reptiles in the Tropical Dry Mixed Deciduous Forest of Anaikatty Hills, Western Ghats, India.
(SACON, 2007) Mukherjee, Debanik; Bhupathy, S.
The western ghats is one of the 34 globally recognized biodiversity hot spots. Among the 506 species of reptiles reported distributed in India 165 are distributed in the Western ghats. The concept of a biotic community may be defined as tn assemblages of various organisms living together and interacting at all trophic levels. The present study was undertaken with the following objectives (1) to know the suitability of various techniques for sampling reptiles in tropical mixed dry forest (2) To study aspects of population of reptiles in the Anaikatty hills in terms of species richness, diversity and relative abundance (3) to understand the patterns of resource use by reptiles at various spatio-temporal level.
