Neotropical Cardinalidae consists of 40 species in 10 genera that have diversified across the Americas. We provide quantitative information on the preformative molt of 21 Cardinalidae species of seven genera, plus one Thraupidae species placed within Cardinalidae until recently. From 155 preformative molt cards, we calculated molt extent estimates, computed frequencies of molt patterns, and summarized observed frequencies of wing-feather replacement in wing diagrams. We found 17 species with…

Feather function and the evolution of birds.

It is suggested that future research into avian evolution involving feather function should consider multiple aspects of a feather, including multiple functions, seasonal wear and renewal, and ecological or mechanical interactions.

PREFORMATIVE WING MOLT IN 23 NEOTROPICAL RESIDENT PASSERINE SPECIES

The results suggest that lack of time constraints has a small influence on completeness of preformative molt, at least in Neotropical passerines.

Molt strategies of ten neotropical forest passerine species

The number of inserted molts in the annual molt cycle and topographies resulting from the preformative molt in 10 Neotropical forest passerine species are described and two modes of preforming molt feather replacement are found.

Molt Limits in North American Passerines

"Molt limits," or the boundaries between replaced and retained wing feathers and rectrices during partial or incomplete molts, were investigated in 288 species of North American passerines through

Pattern and Chronology of Prebasic Molt for the Wood Thrush and Its Relation to Reproduction and Migration Departure

It is argued that current reports on overlapping of molt and migration based on observations of molting individuals out of the breeding range could be misleading because some individuals may leave the breeding area to molt in other places before starting a true migration.

Wing‐feather moult phenotypes differ between the preformative and prealternate episodes and along passerine phylogeny

Differential seasonal control of bird moult is suggested with preformative moults being associated with (evolutionarily conserved) somatic demands, whereas prealternate moult are probablyassociated with (rapidly evolving) signalling functions.

The sequence of molts and plumages in painted buntings and implications for theories of delayed plumage maturation

Painted Buntings are one of only six passerines in which molt-migration has been documented and that no subadult males acquire a winter plumage intermediate in color between that of adult males and adult females in winter is the first empirical support for Rohwer et al.

Factors influencing the evolution of moult in the non-breeding season: insights from the family Motacillidae

The results strongly support the presence of prealternate moult and absence of autumn moult as ancestral states in this family and suggest that ontogeny and sexual selection may have played a limited role in shaping prealternates moult in Motacillidae.

THE FIRST BASIC PROBLEM: A REVIEW OF MOLT AND PLUMAGE HOMOLOGIES

A revision validates the flexibility and utility of the H-P system and provides examples of how this modified H- P system can be applied to diverse taxa of birds while reflecting the homology underlying all basic plumage cycles.
