Justification: Although this species may have a restricted range, it is not believed to approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is very large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern. |

| History: |
|

| Range Description: | Major breeding populations of the Greater Frigatebird are found in tropical waters of the Pacific and Indian Ocean, as well as one population in the South Atlantic (Trinidade and Martim Vaz, Brazil). It is predominately sedentary, with immature and non-breeding individuals dispersing throughout the tropical seas with the exception of the east and central Atlantic. |

| Habitat and Ecology: | The Greater Frigatebird breeds on small, remote tropical and sub-tropical islands, in mangroves or bushes and occaisionally on bare ground1. Fish, squid and chicks of other bird species (e.g. Sooty Terns) have all been identified as prey3, 4. It is frequently observed attempting to steal food from other bird species (kleptoparasitism)2. However, this behaviour represents a minor source of energy 2, 3, and they are frequently observed foraging at the coast or inland at most places where they breed3. |
