House Sparrow Dossier

by Carl Strang

What could be more common than a house sparrow? That question seems less appropriate now than it might have a couple decades ago, given the decline in the species’ numbers in recent years in many parts of its range. Nevertheless, if the length of a species dossier was in proportion to the species’ abundance, this should be one of the longer ones. That it is not is a clue that perhaps I have been neglecting to give this bird the attention it deserves. Even the introductory paragraph that I wrote to kick off the dossier in the 1980’s is perfunctory.

Never far from buildings, these birds usually nest in cavities of buildings, light posts, or birdhouses, though sometimes they build large ball-shaped nests in tree or shrub branches. They use much grass and assorted debris and litter in nest construction. The song is an uncomplicated, cheerful chirping sound. Loud “cheep” calls used in agonistic and warning situations. The male has a stiff bowing hopping behavior, with tail and wings elevated, in courtship. They eat seeds and insects. They engaged in vigorous pursuit of emerging termite alates at the East Street house in Carlisle, PA.

Early AU86. Corpus Christi, TX. Young begging by fluttering wings and stretching head toward adult male. He flew to another bush and searched for food grosbeak fashion, little change in perch with much peering at nearby branches in all directions.

The face reveals how the black chin accentuates the bill, possibly a useful feature when facing off with antagonists.

13MY87. Bird foraging in willow tops at Willowbrook. Sits on perch 1-3 seconds, searching nearby vegetation, occasionally reach-probing, changing perches about 8″-2′ apart.

8AP90. Female house sparrow systematically biting off bits of dandelion (leaves) to eat, masticating and swallowing.

17OC92. Vicinity of Cantigny (Winfield, IL) while driving. Kestrel carrying house sparrow low across road. Heavy load for the kestrel. Lost grip, perhaps because of the distraction of my car’s close proximity. Sparrow flew away. Many times I’ve seen kestrels searching vole habitat, carrying or eating mice. This, I believe, is the first bird capture I’ve witnessed.

1JE99. House sparrow picking up insect remains from old coyote feces on trail.

25AU99. House sparrow with several white feathers on tail and wings observed at Willowbrook.

29JA00. House sparrows along with Brewer’s blackbirds, horned larks and juncos feeding on spillage from buffalo feeders at Fermilab.
