Lapland Longspur

Calcarius lapponicus

'Longspur' is for the very long claw on its hind toe, and its scientific name repeats it: Calcarius comes from the Latin for 'spurs.' Lapponicus is for Lapland, in far northern Europe, where it also nests. In Britain it's the Lapland Bunting.

Calcarius comes from the Latin calcaria, 'spurs'; lapponicus means 'of Lapland.'
