* = Many now seen throughout the year
[1] = Certain Nov/Dec dates may have been misID for Black Redstart. However the 11/12 record seems to be a genuine late record for the species.
[2] = There are two Dec records for this species, both over 30 years old. Was Siberian Stonechat ever considered [?] we shall never know.
[3] = Species may now linger into late winter. Usual dates are mid March to October.
[4] = This species has been recorded outside the period shown, however these are for eastern races and not the nominate race that breeds in the UK.
[5] = Species overwinters in small numbers in UK. The main migration beings late March & ends mid/late Oct.
[6] = Confusion with feral birds is quite possible.
