Great crested grebes were first proved to have bred in Pembrokeshire when a pair incubated eggs at Llys-y-fran Reservoir in 1996, the nest later being predated. Although present there in following years, breeding was not proven again until 2004. A pair present with three juveniles in July 2002 was suggestive but at that date they could have come from elsewhere.
Single pairs occupied Rosebush Reservoir from 1995 onwards and were seen to have hatched a chick in 1997. They may well have attempted breeding there in each subsequent year, it being confirmed in 1999, 2002, 2004 and 2006.
Breeding was attempted at Heathfield Gravel Pit in 2005 but was unsuccessful.
