'Harried' by a Crow! This is the second individual present today, joining the 3rd-calendar-year female that has been seen (generally at dusk) since mid-December 2011. Unlike the latter, this new bird appears to be a juvenile, lacking the moult contrast in the upperside of the secondaries, so clearly shown by the older bird. It is also more rufous below and has a more juvenile-like 'banded/stripey' ear covert/collar/boa pattern, and the undertail covs are almost unmarked (richly spotted brown in the older longstayer). Again, the pattern of 3-4 bands on the underside of the outer primaries is typical of 'cyaneus' (eliminating any thoughts of the N. American 'hudsonius' form).
