The gray fork-tailed storm petrel is a small seabird with long wings and a forked tail. It spends almost its entire life in the air over the cold waters of the northern Pacific Ocean.
The Grey Fork-tailed Storm Petrel differs from other storm petrels by its light gray coloration and deeply forked tail. It is important for marine nature because it eats plankton and serves as food for large birds and mammals.
