“…However, it is in striking contrast to most sedentary species in the Southern Hemisphere where Russell (2000) has calculated that the median time to independence was 31.5 days post‐fledging. Our findings for the Yellow‐faced Honeyeater also differ, however, from the prolonged parental care of fledglings reported in two migratory passerines from the Southern Hemisphere (Rufous Whistler Pachycephala rufiventris , Bridges 1994; Leaden Flycatcher Myiagra rubecula , Tremont & Ford 2000).…”

“…Our observation that males generally returned to the study area shortly before females is consistent with the pattern observed in Northern Hemisphere migrants (Gauthreaux 1982, Morton 1992) and a small number of Southern Hemisphere migrants that have been examined (e.g. Robinson 1990, Bridges 1994). The apparent earlier arrival and heightened vocal activity of males compared with females may reflect greater intraspecific competition among males for breeding territories and mates.…”

“…For example, there are very few comprehensive studies of Australian migratory species based on quantitative data gathered from observations of individually marked birds (e.g. Robinson 1990, Bridges 1994, Ford 1998, Tremont & Ford 2000. This recently led Russell (2000, p. 392) to conclude 'Migrants and nomads in the Southern Hemisphere and Tropics are virtually unknown on all continents'.…”

Southern Hemisphere passerines are generally thought to have long breeding seasons and high annual survivorship, but this may reflect a bias resulting from a disproportionate concentration on sedentary species. This study presents a detailed examination of the breeding biology and social organization of a migratory population of a passerine from the Southern Hemisphere – the Yellow‐faced Honeyeater Lichenostomus chrysops. It took place between 1997 and 2000 in the Coranderrk Reserve, Healesville, Australia. Following the birds’ return from migration, breeding commenced in mid‐November, roughly 2 months after arrival. The breeding season was short (3.5–4 months) compared with sedentary honeyeaters occupying the same habitat. Territories (0.19 ± 0.11 ha) were established by males but defended by both sexes against conspecific and heterospecific intruders. Within a breeding season, pairs were multibrooded (mean no. of clutches per season 2.14 ± 0.76, range 1–3) and always re‐nested within the same territory with the same partner. However, only 12.5% of pairs bred together in a subsequent breeding season despite, on many occasions, their partner from the previous season being alive (divorce rate of 75% for males and 66% for females). Females alone built the nest, incubated the eggs and brooded the nestlings. However, males contributed 44.5% of feeding visits to nestlings. The breeding cycle of Yellow‐faced Honeyeaters (clutch size 1–3 eggs, mean 2.4 ± 0.6, n = 84, incubation period 14.4 ± 0.7 days, n = 11, nestling period 13.0 ± 1.7 days, n = 6) was similar to that of sedentary honeyeaters (and Southern Hemisphere Corvidae in general), except that fledglings only remained on the parental territory for 2–3 weeks post‐fledging. At least one young fledged from 32.1% of nests (n = 156). Predation was the major cause of nest failure (74.5% of 106 failed nests). Only 4.4% of nestlings (n = 136) were observed on the study site in subsequent seasons (five males and one female). None of those males was observed on the study site until their second year of life. Adult annual survivorship (ignoring losses due to dispersal) was 43% for females and 51% for males. Our study suggests that if more data were available for the numerous migratory species from the Southern Hemisphere, some apparent differences from northern hemisphere passerines might disappear.

“…This result is thus not consistent with the pattern seen in Europe and North America where migrants tend to produce fewer but larger clutches (Böhning-Gaese et al 2000). The fairly short period of parental care in the Yellow-faced Honeyeater, however, contrasted with sedentary southern hemisphere species and with the Australian migrants Rufous Whistler (Pachycephala rufiventris) and Leaden Flycatcher (Myiagra rubecula) (Bridges 1994;Russell 2000;Trémont and Ford 2000). Several behavioural characteristics of the Yellowfaced Honeyeaters were similar to those in northern hemisphere migrants.…”

“…This species placed nests in sites with much denser foliage than did Western Yellow Robins, and sites with dense foliage are likely to be less available in logged forests within the first 12 months after logging. There is little evidence to support this hypothesis, but Bridges (1994) commented that vegetation microhabitat appeared to be the critical factor in determining nest‐site selection in Rufous Whistlers ( Pachycephala rufiventris ), a closely related species. In addition, the two nests in logged forest contained 60% and 65% foliage within a 50‐cm radius around the nest, which is much higher than the average for whistlers (39.4%).…”

I assessed which resources were critical for bird species that decline after selective logging. I compared foraging and nesting behaviors of Western Yellow Robins ( Eopsaltria griseogularis ), Rufous Treecreepers ( Climacteris rufa ), Golden Whistlers ( Pachycephala pectoralis ), and White-naped Honeyeaters ( Melithreptus lunatus ) before and after logging in jarrah forests used for timber production in southwestern Australia. Species that declined after logging (Golden Whistler, White-naped Honeyeater) foraged in the canopy and displayed little flexibility in foraging behavior. Species that did not decline ( Western Yellow Robin, Rufous Treecreeper) foraged lower, spent a variable proportion of time on the ground and displayed greater flexibility in foraging behavior. Rufous Treecreepers, obligate tree-hollow nesters, and Western Yellow Robins did not alter nesting sites after logging, but Golden Whistlers nested infrequently in logged areas. There were no consistent differences in the nesting ecologies of the two groups, and it is unclear why Golden Whistlers nested infrequently in logged forest. Western Yellow Robins and Rufous Treecreepers used logged forest as frequently after logging as before and did not appear to require unlogged buffers to persist in forests used for timber production. In contrast, Golden Whistlers used logged forests less frequently after logging and moved their territories to include unlogged buffers. Retention of critical resources for Golden Whistlers and White-naped Honeyeaters in logged forest is unlikely to be feasible because of the effects on timber yield, emphasizing the importance of unlogged buffers in forest management.Ecología Comparativa de Cuatro Especies Paserinas en Bosques de Jarrah Usados para la Producción de Madera en el Suroeste de Australia Occidental Resumen: Se llevó a cabo la evaluación de aquellos recursos de importancia fundamental para cuatro especies de aves en declinación después de la tala selectiva. Comparé las conductas de forrajeo y anidación de Eopsaltria griseogularis , Climacteris rufa , Pachycephala pectoralis , y Melithreptus lunatus antes y después de la tala de bosques de Jarrah usados para la producción de madera en el suroeste australiano. Las especies que declinaron después de la tala ( P. pectoralis , M. lunatus ) forrajearon en el dosel y mostraron poca flexibilidad en su conducta forrajera. Las especies que no declinaron ( E. griseogularis , C. rufa ) forrajearon más abajo, emplearon una proporción variable de tiempo en el suelo y mostraron mayor flexibilidad en su conducta de forrajeo. C. rufa , un anidador obligado de huecos de árbol y E. griseogularis , no alteraron sus sitios de anidación después de la tala. Pero P. pectoralis anidó solo ocasionalmente en áreas taladas. No se detectaron diferencias consistentes en las ecologías de anidación de los dos grupos y no es claro porqué P. pectoralis anidó ocasionalmente en los bosques talados. E. griseogularis y C. rufa usaron frecuentemente bosques tanto antes como después de ser talados y ...
