FIGURE 3. Color variation in the Long-tailed Reed Finch Donacospiza albifrons due to age and feather abrasion. From left to right: AMNH 321449 (new definitive basic plumage); AMNH 322059 (slightly abraded definitive basic plumage); AMNH 388281 (very abraded definitive basic plumage); AMNH 519693 (new first basic plumage); and AMNH 388282 (abraded juvenal plumage, molting to the first basic plumage). All specimens were collected in the southern range of the species.Published as part of Lopes, Leonardo Esteves, 2017, Morphological variation of the Long-tailed Reed Finch Donacospiza albifrons (Vieillot, 1817) (Aves: Thraupidae), pp. 201-218 in Zootaxa 4329 (3) on page 207, DOI: 10.11646/zootaxa.4329.3.1, http://zenodo.org/record/100243
