Death smells different at various stages of decomposition, some describe it like rotten meat only much worse. It is not a smell you will like or will ever forget.
Birds do have a sense of smell. It is more developed in larger birds such as the albatross and fulmars. Many seabirds can smell fish oils from a very long distance (25kms in some cases), they can also smell pheromones that fish give off when distressed. Smaller birds have a less developed sense of smell but some rely partly on smell to navigate and to choose nesting materials. Some birds (like ducks) can smell when the female duck is ready to mate. So it is possible that birds partially use scent to detect predators but the placing of their eyes on either side of their head is likely to be the better option for avoiding predators.
