The gadfly petrels or Pterodroma are a genus of about 35 species of petrels, part of the seabird order Procellariiformes. The gadfly petrels are named for their speedy weaving flight, as if evading gadflies (horseflies). The flight action is also reflected in the name Pterodroma, from Ancient Greek pteron, "wing" and dromos, "runner".[1]
The short, sturdy bills of these medium to large petrels are adapted for soft prey that they pick from the ocean surface. They have twisted intestines for digesting marine animals that have unusual biochemistries.
Their complex wing and face marking are probably for interspecific recognition.
These birds nest in colonies on islands and are pelagic when not breeding. One white egg is laid usually in a burrow or on open ground. They are nocturnal at the breeding colonies.
While generally wide-ranging, most Pterodroma species are confined to a single ocean basin (e.g. Atlantic), and vagrancy is not as common amongst the genus as in some other seabird species (c.f. the storm petrels Hydrobatidae).
Species in taxonomic order
The taxonomy of the gadfly petrels is being refined at the moment. Several genera have been split off over time, as they are closer to the procellarine and Puffinus shearwaters. Some subspecies have been raised to full species rank. The arrangement given here is traditional, but annotates the changes proposed by Austin (1998)[2] and Bretagnolle et al. (1998).[3] For the current taxonomy, see also Brooke (2004).[4]
- Genus Pterodroma

- Pterodroma arminjoniana, Trindade petrel (Atlantic Ocean basin, with eccentric breeding locality in the Indian Ocean at Round Island, Mauritius)
- Pterodroma heraldica, herald petrel (Pacific Ocean basin) – recognized by the IOC and Clements.[5] However, the SACC has not recognized the split yet.
