Significant Difference

House Wrens (Troglodytes aedon Vieillot, 1809) regularly add spider egg cases (Arachnida: Araneae) to their nests, which may be an example of heterospecific cleaning. This behavior involves one animal employing another to remove parasites from their nests. In House Wren nests, juvenile spiders hatching from egg cases may facilitate the reduction of mites that feed on nestlings. We tested this ectoparasite reduction hypothesis by monitoring House Wren nests for spider egg cases and by collecting completed nests to compare the number of spider egg cases and Dermanyssus hirundinis (Hermann, 1804) mites. No significant relationship was found between the number of spider egg cases and number of D. hirundinis mites in nests. We also found no significant relationship between the number of D. hirundinis mites in nests and the body condition of nestlings. Finally, no significant difference was found between the number of D. hirundinis mites in early versus late season nests, but significantly more spider egg cases were added to late season nests. Of a subsample of spider egg cases dissected, we found that 28% contained spider eggs or embryos. We also identified three species of juvenile spiders from House Wren nests using DNA barcoding. Overall, we found no evidence that spider egg cases reduce the number of D. hirundinis mites or engender better quality offspring in House Wren nests.

Abstract Since early in its taxonomic history, placement of the Socorro Wren (Thryomanes sissonii) has been an object of contention. Of particular interest is its current placement in the genus Thryomanes, which makes that genus ditypic and leads to an odd biogeographic scenario for the Socorro Wren's colonization of Socorro Island. We assessed its phylogenetic position by analyzing 516 base pairs of mitochondrial DNA sequences from the ND2 gene of this species and 14 additional wren taxa. Contrary to its present placement, the Socorro Wren is nested phylogenetically within the House Wren species complex, being placed as sister to the clade Troglodytes aedon + T. musculus. The current hypothesis (i.e. sister to Thryomanes bewickii) is strongly invalidated by our analysis. Our analyses indicate that the most appropriate taxonomic classification for the Socorro Wren is Troglodytes sissonii. Posición Filogenética y Ubicación Genérica de Thryomanes sissonii

Lines Of Evidence

Abstract The degree of hatching synchrony in clutches of passerine birds frequently varies among species and among individuals of the same species. Many hypotheses have been proposed to explain why some eggs hatch several days after others in a clutch. We tested one of these hypotheses, the energetic-constraints hypothesis, which proposes that females in poor physical condition postpone initiating incubation and hatch their clutches synchronously, whereas females in good condition begin incubation early and hatch their clutches asynchronously. We tested the hypothesis using the House Wren (Troglodytes aedon) because recent studies have found little difference in productivity between synchronously and asynchronously hatching clutches in this species, suggesting that the degree of hatching synchrony varies for reasons unrelated to nestling growth and survival. We used logistic regression to test the dependence of the degree of hatching synchrony on each of two measures of female condition. We found no relationship between female condition and degree of hatching synchrony. These results and two other lines of evidence are inconsistent with the energetic-constraints hypothesis as an explanation for variation in degree of hatching synchrony in this House Wren population. ¿Predice la Condición de las Hembras la Sincronía de Eclosión en Troglodytes aedon? Resumen. Con frecuencia, el grado de sincronía en la eclosión de nidadas de aves paserinas varía entre especies y entre individuos de la misma especie. Se han propuesto muchas hipótesis para explicar por qué algunos huevos eclosionan varios días después que otros en una misma nidada. Pusimos a prueba una de esas hipótesis, la de las limitaciones energéticas, que propone que hembras en mala condición física postponen el inicio de la incubación y sus nidadas eclosionan sincrónicamente, mientras que aquellas en buena condición inician la incubación temprano y sus nidadas eclosionan asincrónicamente. Pusimos a prueba la hipótesis usando a Troglodytes aedon, pues estudios recientes en esta especie han encontrado pocas diferencias en productividad entre nidadas de eclosión sincrónica y asincrónica, lo que sugiere que el grado de sincronía en la eclosión varía por motivos no relacionados con el crecimiento y supervivencia de los pichones. Utilizamos regresión logística para evaluar el grado de dependencia de la sincronía de eclosión en dos medidas de condición física de las hembras. No encontramos ninguna relación entre la condición de las hembras y el grado de sincronía en la eclosión. Estos resultados y otras dos líneas de evidencia son inconsistentes con la hipótesis de las limitaciones energéticas como una explicación para la variación en el grado de sincronía de eclosión en esta población de T. aedon.

Abstract During the breeding season, avian pairs coordinate interactions with songs and calls. For cavity nesting birds, females inside nest boxes may rely on male vocalizations for information. Anthropogenic noise masks male songs, which could affect information gained by females. We explored song transmission from a female house wren (Troglodytes aedon) perspective, testing the hypothesis that noise masking alters songs that reach females inside nest boxes. We broadcast songs at three distances up to 25 m from nest boxes and re-recorded songs using two microphones, positioned inside and outside nest boxes. We measured signal-to-noise ratios and cross-correlation factors to estimate the effects of masking on transmission. In noise, songs received inside nest boxes had lower signal-to-noise ratios and cross-correlation factors than songs recorded outside of boxes, and these effects decreased with distance. For females, noise may reduce information conveyed through male songs and in response pairs may need to adjust their interactions.
