I'll phone yourself and Michael later in the week Herbert. We are still hopeful of more returning yet. With such a small liberation, it was always a hard ask, but from little acorns, giant oaks are born.
W McCann & A Brown timed a pigeon from Birsay today. Six more that I know of from Thurso, so pigeons are still working. One reported in Inverness, so it appears they may have went down the Great Glen.
