This verbatim report from last Sunday would indicate that the spring migration is underway.
"The Marsh was reliable for raptors with single female Hen Harrier and Marsh Harrier over the saltmarsh and a male Sparrowhawk along the lanes. There seemed to be plenty of Pink-footed Geese with itchy feet; several hundred overhead so I wonder if the Norfolk birds have started arriving as as Lancs is a staging post on their northbound journey back to the breeding grounds. No doubt there'll be a few goodies in the 'Pink's over the coming weeks. It was good to see some Golden Plovers in the fields yesterday at HOM too. A bit flighty but we counted at least 150 with 40 Lapwings. The latter were displaying over the stubble and with Skylarks in full song over the pastures it was just like spring and a Siskin bombing north must've been a migrant."
A siskin has also been seen on a feeder in the north part of Southport and a Ring-necked Parakeet!
