Migrant birds recorded from
March to May and August into November. Occasional birds seen
outwith these months.
The earliest record of a
spring migrant was on the 29th – 30th March, 2003. The earliest
autumn bird was seen on the 10th – 11th August, 1996 and
the latest on the 9th November at least.
Numbers are usually in the
hundreds, although occasionally there can be a fall of birds which takes daily
totals into the 1000s. In mid October, 1966, there was such a fall of 3000
birds (Pennington et al.
2004) and this remained the record until 2004, when on the 22nd October,
at least 5000 birds were strewn across the island!
