## European Storm Petrel

### Hydrobates pelagicus

The European Storm Petrel or Storm Petrel (Hydrobates pelagicus) is a small bird of the storm-petrel family, Hydrobatidae, part of the seabird order Procellariiformes. It is the only member of the genus Hydrobates.
The Storm Petrel is a small bird, only the size of a House Martin, which it superficially resembles with its dark plumage and white rump. It is 15-16 cm in length with a 38-42 cm wingspan. It can be distinguished from Leach's Storm Petrel and Wilson's Storm Petrel by its smaller size, different rump pattern and flight behaviour.
