Passage migrant in small numbers chiefly on the islands, but males heard singing two years (1941 -2) at Nevern. No nests found.

Wednesday, July 4, 2012 at 12:28PM Pied Flycatchers were first proved to breed in Pembrokeshire, at Ffynone, in 1978 but they may have bred at Llancych in 1936. Colonisation of Pembrokeshire took place in the late 1970’s and 1980’s and the 1984-88 survey estimated the county population was about 100 pairs by 1988. Since then the population has undergone a decrease, so by the time of the 2003-07 survey there had been a 39% contraction in its county distribution. Even during the course of the survey there was known contraction, those breeding at Blackpool Mill Leat in 2003 having disappeared by 2004. It is estimated that 30 pairs were nesting in Pembrokeshire by the end of 2007. Pied Flycatchers decreased in the UK by 49% between 1996 and 2006 according to the BTO, early indications being because they have not adapted to peak food availability being advanced as a result of the trend towards earlier springs. Consequently the Pied Flycatcher has been amber-listed under the Birds of Conservation Concern 3 (Eaton et al., 2009).

Mathew (1894) considered the Pied Flycatcher to be a rare visitor and did not personally encounter one, though he knew of occurrences at Stackpole and Pembroke. Lockley et al. (1949) stated that it was a passage migrant in small numbers.
Lloyd suspected a pair was breeding at Lancych in 1936 and Lockley et al. noted that a singing male was at Nevern in 1941 and 1942 but that no nest was found. They were found breeding at Ffynone from 1978 onwards and a pair bred in a nest box at the Rhos in 1983. The Pied Flycatcher has subsequently further colonised Pembrokeshire and by the end of the Breeding Birds Survey of 1984-1988 at least 100 pairs were breeding (see map).
This colonisation has taken place while long-established populations elsewhere, e.g. in mid-Wales, have been at a high level, and also at a time when trees that replaced those cut down during World War II reached suitable maturity. Several nest box schemes such as that at Pengelli Forest Nature Reserve have also benefited Pied Flycatchers. Similar schemes operating in the 1960s did not attract the species, so presumably there was not then any surplus in other populations which could provide colonists.
Up to four at a time pass through coastal districts in the spring between 14 April and 27 May, being most noticeable on the islands of Skomer and Skokholm.
They are recorded passing through the islands and most coastal areas in the autumn between August and 27 October, with up to ten occurring at individual sites.
