Abstract
The occurrence of seabirds in Congo waters is poorly known and therefore
we recorded the daily presence of seabirds during a geophysical survey.
The most commonly encountered seabird species included small migratory
terns: Arctic Tern (Sterna paradisaea), Common Tern (Sterna hirundo), West
African Crested Tern (Thalasseus albididorsalis) and Wilson’s storm-petrel
(Oceanites oceanicus). Parasitic Jaeger (Stercorarius parasiticus) and Sooty
Shearwater (Ardenna grisea) were also recorded. Unusual visits of a land
birds were also recorded, including green-backed (mangrove) heron
(Butorides striata), an African Paradise flycatcher (Terpsiphone viridis) and
an African Green Pigeon (Treron calvus).

Purpose
The main purpose of this study was to contribute information on the
distribution and occurrence of seabirds sighted during a geophysical survey
spanning mainly shallow coastal waters but also offshore waters.
|
Supplemental information
The seabird data were collected opportunistically. Most of the sightings did not
record time and number of animals. It should be taken as presence.
