Why are blackbirds tied to winter?

The end of January in the Northern Hemisphere can be quite cold, as it is near the midpoint of winter. According to Italian folklore, the last three days of January are the coldest of the year and are referred to as the 'days of the blackbird.' One local legend gives a fun take on how blackbirds got their dark feathers: To protect her young chicks from the cold Northern Italian winter, a mother bird with white feathers built her nest in a chimney. After her once-white chicks emerged, their feathers had turned black from the chimney's soot, and from that day on, all such birds were born as 'blackbirds.'
