About Sparrows

North Louisiana's sparrow family fills every brushpile, every weedy field, every cattail margin, and every parking lot in the 26 parishes with brown, streaky, ground-feeding birds that humble beginners and veterans at roughly equal rates. Fourteen of them show up regularly, and the whole group dressed in shades of brown, tan, gray, and rufous with streaked breasts, striped crowns, and a collective refusal to sit still on an exposed perch for longer than three seconds. You either love the puzzle or you throw the field guide at the brushpile and drive home.

The Winter Invasion

North Louisiana's sparrow population explodes between October and April, when breeding populations from across Canada and the northern United States migrate south and fill the region's fields, hedges, and brushy edges with a density of small brown birds that the summer months do not approach. Dark-eyed juncos arrive from the boreal forest. White-throated sparrows arrive from the northeastern woodlands.

White-crowned sparrows arrive from the tundra and the montane West. Fox sparrows arrive from the boreal forest's deepest thickets. Savannah sparrows arrive from the northern grasslands and the Arctic. The resident song sparrows and eastern towhees that stayed year-round suddenly share their habitat with a winter sparrow community that outnumbers the summer community by a factor of three or four, and every hedgerow that contained two sparrow species in July contains eight in January.

The winter sparrow community sorts by habitat with enough consistency that a birder who learned the habitat tastes can predict which sparrow occupies which microhabitat before the binoculars come up. The juncos scratch through leaf litter at the brushpile edge. The white-throated sparrows scratch through deeper leaf litter in the hedge interior. The white-crowned sparrows feed on the ground near the hedge margin. Fox sparrows dig through the deepest leaf pile under the densest shrub.

Song sparrows work the brushy ditch edge near water. The chipping sparrow picks seeds from the open lawn. The savannah sparrow flushes from the short-grass field beyond the fence. The swamp sparrow chips from the cattail margin. Each bird carved a niche from the same general landscape, and each bird stays faithful to that niche throughout the winter.

The Ground-Level World

Every sparrow in North Louisiana feeds on or near the ground. Hawks hit them from above, cats hit them from the side, snakes hit them from below, and the whole family learned to deal with it. If you want to attract sparrows to a feeder, keep it low: ground-scattered seed, a platform tray, and dense cover within diving distance. A feeder designed for sparrows sits at knee height or lower.

Escape cover within two body-lengths makes the difference between a feeder that gets visited and a feeder that gets ignored. Millet, cracked corn, and sunflower seed on or near the ground beat hanging tubes at chest height every time. Sparrows feed below the knee. Meet them where they already planned to eat.

Most of the family scratches for a living. Juncos, white-throated sparrows, white-crowned sparrows, fox sparrows, song sparrows, and eastern towhees all kick both feet backward simultaneously to clear leaf litter and expose seeds. The towhee scratches hardest. The junco scratches lightest.
