I had a siskin on my bird feeder this weekend for the first time in months. This seems to be forming a pattern of having siskins visit the garden in very early spring but not being present in summer or mid-winter. Over several years I've had siskins almost exclusively in March and April. This has been the case both my 2 recent homes. Both homes have been sea-level, suburban and close to farmland in east Fife) or central (Falkirk) Scotland not close to any typical siskin breeding grounds. This seems strange timing to me especially as a small number of birds will sometimes hang around for several weeks. Is there any obvious reason for this timing?
