Why do Procellariiformes have a strong sense of smell?
The order has a few unifying characteristics, starting with their tubular nasal passage which is used for olfaction. Procellariiformes that nest in burrows have a strong sense of smell, being able to detect dimethyl sulfide released from plankton in the ocean.
How are Procellariiformes able to locate their nests?
This ability to smell helps to locate patchily distributed prey at sea and may also help locate their nests within nesting colonies. In contrast, surface nesting Procellariiformes have increased vision, having six times better spatial resolution than those that nest in burrows.
What kind of food does a Procellaria petrel eat?
While some other species of fulmarine and Procellaria petrels also take carrion, the diet of most species of albatrosses and petrels is dominated by fish, squid, krill and other marine zooplankton. The importance of these food sources varies from species to species and family to family.
