NEST BUILDING IS AN INDICATOR OF PARENTAL QUALITY IN THE MONOGAMOUS NEOTROPICAL BUFF-BREASTED WREN (THRYOTHORUS LEUCOTIS)

摘要: Abstract In species with long-term partnerships, optimal mate preferences may differ from actual choice, and pair displays that advertise individual quality be expected. We examined the relationship between nest-building nestling-provisioning effort in Neotropical Buff-breasted Wrens (Thryothorus leucotis) to determine whether male or female expenditure during nest construction was used as an indicator of subsequent parental ability. build two types: breeding nests for raising offspring, “dormitory“ built year-round by pairs roosting overnight. The building males greater than their mates dormitory nests, whereas were similar breeding-nest nestling provisioning. Despite large within-sex variation provisioning efforts, within significantly positively correlated both types feeding....
