Abstract

The Sikkim Himalaya is the potential region for the fauna and flora which underpin the roles in economic, social, cultural and ecological aspects. The fauna of Sikkim is basically significant for the ecological network which are blended with the mountain ecology having the mountains' greatest value of the sources of major rivers, and many smaller ones. These play significant role for capturing moisture from air masses and the precipitation reflecting the unique climatic condition. Thus, the mountain ecosystem of Sikkim is an important factor for the biodiversity. Such ecological niche of Sikkim in context to the migratory and resident birds of Sikkim studied. The experiences of one of tribe of Sikkim, Lepcha, on the chirping sound of birds were fascinating who lives in close proximity with nature and agriculture production. This community uses these experiences for the agriculture production and management. The sounds of birds are considered as indicators of threats, climate or environment change etc from their experiences. Hence, this paper presented the study of migratory and resident birds of the Sikkim Himalaya of Dzongu where on the experiences of signals of these birds are included with respect to the biodynamic activities of agriculture. The observations of 25 birds, Strix aluco; Cuculus poliocephalus, Taccocuales chenaultii, Pericrocotus flammeus; Micropternus brachyurus, Nisaetus nipalensis, Psarisomus dalhousiae, Garrulax leucolophus; Eudynamys scolopaceus; Lophophorus impejanus; Trochalopteron affine; Apus melba; Psilopogon asiaticus; Myophonus caeruleus; Ketupa zeylonensis; Orthotomus sutorius ; Tragopan satyra; Grus virgo; Cacomantis merulinus; Cuculus canorus; Psilopogon virens; Bubo bubo, Parus monticolus; Cuculus of Dzongu, Sikkim. The enumerated list contains local names, habitat, characters, altitude and biodynamic utilities of migratory as well as resident birds.
