AbstractI studied molt and plumage in the ‘Elepaio (Chasiempis sandwichensis), a monarch flycatcher endemic to the Hawaiian Islands, at Hakalau Forest National Wildlife Refuge on the island of Hawai‘i from 1994–1997. I captured birds in mist nets, examined them for molt, measured their plumage color with Munsell color chips, and followed them for several years to document plumage changes. Male and female Hawai‘i ‘Elepaio exhibited three distinct post-juvenal plumages, first basic, second basic, and definitive basic, and thus have a two-year delay in plumage maturation. ‘Elepaio have a single annual molt, so there are no alternate plumages. The first prebasic molt is partial, but all subsequent molts are complete. The first basic plumage is juvenile-like and sexually monochromatic. The second basic and definitive basic plumages are sexually dimorphic in throat color. In each sex the second basic plumage resembles definitive plumage. Age-related plumage changes include increases in the whiteness, number, and length of contrasting tips to feathers on the throat, rump, wing coverts, and tail. Subadults do not molt fewer body feathers than adults and produce many feathers that are not adult in coloration, indicating the subadult plumages are not caused by a molt constraint. Appearance of the subadult plumages is consistent in some respects with juvenile mimicry, but the subadult plumages are unlikely to function in sexual mimicry.Desfase de Dos Años en la Maduración del Plumaje del Macho y la Hembra de Chasiempis sandwichensisResumen. Entre 1994–1997 estudié la muda y el plumaje de Chasiempis sandwichensis, un monarca atrapamoscas endémico de las Islas de Hawai, en el Refugio Forestal Nacional de Vida Silvestre Hakalau en la Isla de Hawai‘i. Capturé aves empleando redes de niebla, las examiné para establecer la muda, medí el color de sus plumajes con fichas de colores Munsell, y las seguí durante varios años para documentar cambios en el plumaje. El macho y la hembra de C. sandwichensis exhibieron tres plumajes post-juveniles diferentes, básico primero, básico segundo, y básico definitivo, mostrando así un desfasaje de dos años en la maduración del plumaje. La primera muda pre-básica es parcial, pero todas las mudas subsecuentes son completas. El primer plumaje básico se asemeja al del juvenil y es similar para ambos sexos. El segundo plumaje básico y el básico definitivo presentan dimorfismo sexual en el color de la garganta. En ambos sexos el color del plumaje básico se asemeja al del plumaje definitivo. Los cambios en el plumaje relacionados a la edad incluyen un incremento en blancura, número, y largo de la punta contrastada de las plumas de la garganta, rabadilla, cubiertas alares y cola. Los subadultos no mudan menos plumas corporales que los adultos y producen muchas plumas que no son como la de los adultos en coloración, indicando que el plumaje de los subadultos no responde a una limitante de la muda. La apariencia del plumaje de subadultos es consistente en cierto sentido con la imitación de juveniles, pero el plumaje de subadultos es improbable que funcione como imitación sexual.

To ensure dispersal, many parasites and pathogens behaviourally manipulate infected hosts. Other pathogens and certain insect-pollinated flowers use sexual mimicry and release deceptive mating signals. However, it is unusual for pathogens to rely on both behavioural host manipulation and sexual mimicry. Here, we show that the host-specific and behaviourally manipulating pathogenic fungus, Entomophthora muscae, generates a chemical blend of volatile sesquiterpenes and alters the level of natural host cuticular hydrocarbons in dead infected female house fly (Musca domestica) cadavers. Healthy male house flies respond to the fungal compounds and are enticed into mating with dead female cadavers. This is advantageous for the fungus as close proximity between host individuals leads to an increased probability of infection. The fungus-emitted volatiles thus represent the evolution of an extended phenotypic trait that exploit male flies' willingness to mate and benefit the fungus by altering the behavioural phenotype of uninfected healthy male host flies.
