The Two-Barred Crossbill — Loxia Bifasciata (C. L. Brehm)
This species, whose true home is in Northern Russia and Siberia, has visited this country in small flocks on several occasions.
It may easily be distinguished from the Common Crossbill by the two white wing-bars; it is also rather smaller in size. Length 6·25 in.; wing 3·7 in.
