  abstract = {{N}ewly built sewage farms in the north of {S}enegal, near the town of {S}aint-{L}ouis and {L}ouga have proved to be very attractive to {L}ittle {G}reves : there was always more than 50% of those counted during wetland censuses between {O}ctober and {J}uly, and more than 80% for eight of these months. {P}revious censuses didn't focus on grebes, so there is no proof of increase, although this seems likely. {B}lack-necked {G}rebe were observed only once in {S}enegal before their discovery at {S}aint-{L}ouis sewage farm in 1990. {S}ince then it has been found regularly there between {N}ovember and {F}ebruary, numbers varying between 25 and 34. {T}he site has become less used with time, especially because of human disturbance, but {B}lack-necked {G}rebe have since been found in equivalent numbers on a lake at {G}uiers and a lagoon in {M}auritania.
