Sclater's Nightingale-thrush Catharus maculatus

Current view: Data table and detailed info

Taxonomy

Taxonomic note
Catharus dryas has been split into Gould's Nightingale-thrush C. dryas and Sclater's Nightingale-thrush C. maculatus following Halley et al. (2017), whose conclusions are fully backed when the Tobias yardstick approach (Tobias et al. 2010) is applied to their data. C. maculatus emerges as a species with; effect size for wing-length ‒3.49 (score 2); effect size for bill shape 1.1 (score 1); streaked throat (1); absence of subtle yellow-olive wash to upper- and underparts in life (?1); effect size for number of notes in song ‒5.26 (3); effect size for song duration 8.12 (3).
