The Breeding Birds of Kansas — Themes and Context

A Data-Driven Approach to Breeding Seasons

Johnston organizes his analysis around temporal patterns, using tables and histograms to present egg-laying records. For example, the Eastern Phoebe is identified as 'the only double-brooded flycatcher in Kansas,' with modal dates of April 25 for first clutches and June 5 for second. The author tracks seasonal progression in clutch-size, noting a decline from 4.4 eggs in April to 3.6 in June. Such granularity is typical: the Great Crested Flycatcher's 22 records span May 11 to July 10, with a modal date of June 5. These details emerge from field observations, not speculation.

Habitat and Distribution as Context

Each species account pairs temporal data with habitat preferences. The Eastern Phoebe favors 'woodland edge and riparian groves' near human structures, while the Say Phoebe inhabits 'open country' in western Kansas. The Acadian Flycatcher is 'uncommon' in eastern Kansas, with too few records to reliably define its breeding season. Johnston also notes distributional limits: the Traill Flycatcher nests only in extreme northeastern Kansas, with records from just across the Missouri border. These details ground the temporal data in geographic reality.

The Limits of the Record

Johnston repeatedly acknowledges gaps. For the Acadian Flycatcher, he states that 'available records of breeding by this species in Kansas are too few to indicate reliably the span of the breeding season.' The Traill Flycatcher is noted as 'only recently found nesting within Kansas' and excluded from broader analyses. Such honesty is a strength: the reader sees not just conclusions but the evidentiary basis. The author also credits 'several dozen people' for observational effort, underscoring the collaborative nature of the data.

A Work of Its Time and Place

Published as part of the University of Kansas Museum of Natural History series, this volume reflects mid-century ornithological practice: quantitative, specimen-based, and focused on life history. The prose is concise, with tables and figures carrying much of the analytical weight. The book's structure—introduction, habitat overview, species accounts—mirrors its dual aim: to synthesize existing knowledge and to identify 'outstanding avenues of profitable future work.' Readers should approach it as a primary source, not a field guide.

Johnston's monograph rewards careful reading of its tables and histograms, which often convey more than the text. The species accounts are best consulted alongside the introductory sections on distribution and breeding seasons, where the analytical framework is laid out. For those interested in Kansas birds or the history of American ornithology, this work offers a snapshot of a state's avifauna at a particular moment—and a reminder of how much fieldwork underpins even a modest summary.

I found myself thinking about that old Kansas bird study—how it quietly mapped the precise moments each species chose to nest. That patient attention to place reminded me of something gentler, The Foot-path Way — Context and Discussion, which lingered with me the way a familiar trail does. Both felt less like data and more like a quiet way of being somewhere.
