Circumpolar Species

Of the four species of longspur, Lapland Longspur is the most abundant with a worldwide population estimated at 150,000,000 breeding over a large circumpolar range.  On the Chico, they are seen on occasion in November into early December if you walk in shortgrass prairie and get lucky. Like all longspurs, their hind toe is elongated as implied in their scientific name, Calcarius laponnicus, Calarius from Latin calcar, or spur, referring to their very long hind toe.  In summer they are beautiful birds, but like the other longspur species, they are dull-colored during winter months and unlike many songbirds who molt to obtain a breeding plumage, longspurs obtain their breeding plumage by a slow wearing of their feather tips.
