Well, this round two of our intrepid washers sniffed out the correct definition, H. The scent of cooked meat or other food. Bobyoungbalt and tsuwm flew right past all the nest-related bluffs to get right to the meat of the situation. I don't know much about the word (perhaps one of our correct guessers can illuminate?) aside from the internet citation I found that noted that it was considered "obsolete" in a 1919 Webster's entry.

consuelo picked up 4 votes for her straightforward "Type of animal that forms a nest in which to deposit its eggs" and Bobyoungbalt got 3 people to go for his more metaphorical "A small loft, sometimes referred to as a "birdsnest" high up (usually in the rear, sometimes in a transept or over the roodscreen) of a large church or cathedral, usually for an antiphonal organ". The current point standings are below the definitions.

J. Nidor is of Old French origin. The beds of royalty were covered in the finest of linens; often decorated with gold thread embroidery. The common people used to describe these as nids d'or - beds of gold. Over time it became the one word, nidor, and came to mean any residence that was overly ostentatious. It is rarely heard today - and usually used in a derogatory fashion. - belMarduk belMarduk (no point)

And with that I'd like to pass the HogMaster hat onto the next victim (be careful, it's heavy, and watch out for the feathers). Any takers? Thanks to all who played, especially the newer members of the community, for keeping HogWash alive. Good luck, and good washing!
