Timing and extent of the molts of adult red-eyed vireos on their breeding and wintering grounds
Article Abstract:
A study examined the timing and extent of the molts of adult red-eyed vireos on their breeding and wintering grounds. This research investigated molting behavior in three different sites in northeastern North America. Findings revealed that adult red-eyed vireos differ from other vireos and passerines in North America since they do not finish molting on the breeding grounds. No variation in terms of extent of molt was found among sites but timing of the molt was earlier and onset of molt was longer at one site than at the other two sites. Replacement of flight feathers not molted on breeding grounds occur on the wintering grounds starting early January.

Relative costs of prebasic and prealternate molts for male Blue-winged Teal
Article Abstract:
The relative costs of prebasic and prealternate molts for male Blue-winged Teal was studied to compare the masses of its definitive basic and alternate plumages. Furthermore, the study aims to evaluate the hypothesis that nutritional investments in alternate plumages are related to the length of time the plumages are worn. Results reveal that deviations between observed and predicted plumage masses were determined by other factors including nutrition. There was also no evidence that show molting in Blue-winged Teal is caused by nutritional stress.
