The last Partridge I had seen before last September was on Wicklow Head
in 1981.
Apart from 2 small concentrations of wild birds in the midlands I don't
know of any reliable sites for Partridge.(except perhaps introduced
birds in N. Wexford.)
Speaking of which has anyone seen any Red-legged Partridges in recent
times ?

Myself and AMcG where the last persons to see Partridge in Northern
back in 1980 (NIBR 1980/81) though the new Atlas indicated sightings in

The No. of pairs of Wood Warblers in N. Ireland is reported each year in
NIBA reports; there are usually 5 - 10 pairs each year.
