Ornithological biography, Vol. 2 (of 5) — Key Ideas to Explore

Taxonomy as Testimony

Audubon's descriptions are built around precise measurements—bill length, tarsus, wing span—and careful color notation. For Macgillivray's Finch, he gives a full table of dimensions and notes that bills vary greatly with age, a detail that undermines simplistic identification. He also corrects Wilson's figure of Henslow's Bunting, calling it 'incorrect' and asserting that his own illustration is accurate. These passages show Audubon treating taxonomy as a form of testimony, where firsthand observation outweighs earlier published plates.

The catalog subject 'Birds -- North America' is accurate but reductive: the excerpts reveal a work equally concerned with correcting the historical record. Audubon names his sources—Wilson, Jardine—and uses them as foils to establish his own authority.

The Collaborator's Hand

William MacGillivray is listed as contributor, and his presence is felt in the finch description: the species is named 'Macgillivray's Finch,' and its traits are compared to two other species in a systematic way. The text includes a note that MacGillivray's Finch is intermediate in size and combines the coloring of both relatives. This suggests a collaborative method of comparison and classification, not merely Audubon's solo fieldwork.

Yet the excerpts also show Audubon's proprietary voice: he writes 'my friends, my assistants, and myself procured hundreds of specimens.' The volume thus oscillates between collective science and personal narrative, a tension the catalog entry does not capture.

Beyond the Bird: Habitat and Behavior

Audubon does not limit himself to morphology. For the Red-eyed Vireo, he describes foraging behavior—'moving about, and along the branches or the twigs of the trees, by light hops'—and contrasts it with flycatchers. This behavioral observation is woven into the taxonomic argument: Henslow's Bunting is distinguished partly by its habitat (dry meadows, not salt marshes).

The excerpts also include a lengthy transcriber's note listing inconsistencies in spelling and possible errors, reminding readers that the text is a reconstruction from multiple print editions. The volume's authority is thus mediated by editorial intervention, a layer the original catalog does not acknowledge.

Readers should approach this volume as a hybrid: part field guide, part taxonomic polemic, part collaborative manuscript. The catalog subject 'Birds -- North America' is accurate but incomplete. Pay attention to the footnotes and the transcriber's notes, which reveal the text's contested history. Audubon's voice is confident, but the evidence shows a scientist constantly defending his ground against peers.

Rain drummed on the windowsill that afternoon while I followed Audubon’s patient corrections, noticing how each sharpened observation seemed to soften the man behind the pen. His partnership with MacGillivray lingered—two voices, one vision. That quiet collaboration nudged me toward Introduction to our bird friends, volume 2 — Background and Themes, where the same gentle trust in careful watching, unhurried, remains. The rain never really stopped.
