It turns out, the loose feathers that cover the bird's chest region is what allows heat insulation and buoyancy in water for certain bird species. As explained in previous posts, the feathers consist of open air sacks in the center that allows heat to be stored.

One interesting fact is birds tend to use their down feathers to insulate their eggs as well: by pulling their own feathers off, female birds are able to keep eggs warm by surrounding their nests with down feathers and emitting their heat onto the insulators.
