Description

This presentation was presented in front of 'Ornithology Course' Conducted By Abasaheb Garaware College, Pune and Ela Foundation in Year 2008. This Presentation gives Ornithological perspective of the Surveillance work, and field experiences during this work. Aditya Ponkshe and I jointly presented this lecture, as we were invited as Faculty at the Course.

Wetlands bearing congregation

Areas adjacent to poultry farms

Fecal Sampling Components of a bird dropping Virus if present is seen in ‘pellet’ (GI excretion) Uric acid : (Renal excretion), ‘splash’ GI excretion, ‘Pellet’

Components of a bird dropping

Virus if present is seen in ‘pellet’ (GI excretion)

Collection Collection of fresh feces from the dropping 5 droppings from same species were pooled Collection of other samples like pellets Proper numbering and labeling Transport on ice

Sentinel Species

Hirundinidae Columbidae Sturnidae Passeridae Bridge Species

Characterization of Fecal matter of Different Species For correct identification of dropping Find Isolated flock of a single species and collect the fresh dropping from that particular place Or observe a bird
