Bird Guide: Land Birds East of the Rockies, from Parrots to Bluebirds — Reading Companion

Precision in Plumage and Measurement

Reed’s descriptions rely on measurable traits. For the Barn Swallow, he notes the female is “duller plumaged and with a less deeply forked tail than the male,” and gives a length of 7½ inches. The Tree Swallow is distinguished by being “entirely white below” in both sexes, while the Bank Swallow is identified by a “conspicuous band across the breast.” Such details allow readers to differentiate similar species in the field.

Egg dimensions are given in hundredths of an inch—for example, the Barn Swallow’s eggs are “white dotted and spotted with reddish brown (.80 × .55).” This precision reflects Reed’s background as an oologist and curator.

Behavior and Habitat as Identification Clues

Reed frequently uses behavior to separate species. The Cliff Swallow “plaster[s] its nests on the outside of barns … up under the eaves,” while the Barn Swallow nests on “inside beams and rafters.” The Tree Swallow “skimm[s] over ponds” and roosts on “telephone wires,” often in rows. The Rough-winged Swallow gets its name from the “stiff and bristly” outer primary feather.

These behavioral notes are not mere color; they serve as diagnostic tools. Reed also notes colony sizes: Cliff Swallows sometimes form “colonies of several thousand,” and Bank Swallows nest “in colonies in holes in banks.”

Conservation Through Quantification

Reed’s preface is a sustained argument for bird protection based on insect consumption. He cites specific figures: a Chickadee feeds its young “about two hundred times a day” with “plant lice,” and a Cuckoo consumes “from 50 to 400 caterpillars” daily. He extrapolates to state-level totals, asserting that Massachusetts birds eat 2.56 billion insects per day.

This approach frames bird preservation as a practical necessity, not sentiment. Reed writes that “the best means of protection is the disseminating of knowledge,” positioning his guide as a tool for public education. The tone is urgent but grounded in arithmetic.

Reed’s guide rewards careful reading of its compact entries. Note how he pairs physical measurements with behavioral cues—a bird’s foraging style or nest placement often matters as much as its color. The egg dimensions, given in decimals, reflect an era when field ornithology demanded precision. Readers interested in the history of conservation rhetoric will find the preface’s insect-consumption calculations particularly striking.

I’ve spent many evenings with Chester Reed’s careful counts of caterpillars, his quiet arithmetic for saving orchards. The same earnest voice seems to echo in Some Common Birds Useful to the Farmer (1915 edition) — Themes and Context, where patience and flock-studies meet the plow. They speak to each other across a shelf, the way old friends share a knowing glance. A gentle, useful companionship.
