Over
the past few weeks, our area has been experiencing a small inundation of
Lapland Longspurs in the open fields, especially around the Cobden area. In
fact, the other day, Rob Cunningham and I located at least three large flocks
feeding along the rural roadsides. Normally, we only see a few of these birds
in the spring and fall amongst large flocks of Snow Buntings and Horned Larks.
While these birds are not rare for our area, you do not usually find them in
flocks here.
The
Lapland Longspur (Calcarius lapponicus) is commonly found in the fall and
spring on barren snow-swept fields throughout Southern Canada and the North and
central United States.
The
Lapland Longspur in some ways resembles a House Sparrow in that it has a black
crown, forehead, cheeks, throat and breast. However, unlike the House Sparrow,
it has a reddish brown nape and a white stripe that extends from its eye to the
side of its breast. It has whitish under- parts, and its outer two feathers on
its tail are partly white and partly black.
The
female Lapland Longspur is duller in colour with rufous wing coverts, and she
has a bold, dark triangle that outlines her buffy ear patches.
In
the summer, these birds are residents of our Northern tundra where they reside
in pairs or small family groups in prairies, grassland, stubby fields, dune
areas, and along shorelines. They forage for food on the ground and eat
insects, spiders and seeds from grass and sedge. In the winter they eat mainly
weed seeds.
The
Lapland Longspur breeds in the Northern tundra. The male Longspur courts the
female by singing and chasing the female on the ground. The male rises in front
of the female who is on the ground, singing above her head and gliding back
down with its wings and tail spread.
