Jungle cock is pretty easy to find, and if you contact one of our sponsors you can get personal service from the awesome people working at these shops.
Indian crow on the other hand... you might consider imitation Indian crow, which is fairly common and does the trick. Not sure what bird they are from but they are shaped similarly and you get a bag stuffed with them for a few bucks. I use them for shell backs on small prawn patterns for early steelhead.
Real Indian crow is hard to find, but for any rare off-the-beaten-path materials you should try Castle Arms in Springfield MA, Bob Marriotts in Orangethorpe CA, and Hunter's in New Boston NH, Quality Fly Fishing in Port Angeles WA - for starters.
Are you tying some classic salmon flies?
