salim ali center for ornithology and natural history  do not offer any courses on bsc in ornithology and natural science.

the institute offers m.sc course on ornithology and conservation biology

phd programmes with collaboration of bharthiar university, saurastra university, gujrat, manipal academy of higher education.

there is rare institute in india which offers bsc in ornithology, however you may do msc or phd courses in ornithology after you completed bsc course in biology related stream like zoology, botany, life sciences etc.

hope it would help.
