Prothonotary Warbler (Protonotaria citrea) Science Article 3 abstract Why do many hosts accept costly avian brood parasitism evenwhen parasitic eggs and nestlings differ dramatically in appearancefrom their own? Scientists argue that evolutionary lag orequilibrium can explain this evolutionary enigma. Few, however,consider the potential of parasitic birds to enforce acceptance bydestroying eggs or nestlings of hosts […]

JUVENILE GRAY JAY PREYS UPON MAGNOLIA WARBLER
Magnolia Warbler (Dendroica magnolia) Science Article 1 abstract A juvenile Gray Jay (Perisoreus canadensis) was observed to capture, kill, and eata healthy juvenile Magnolia Warbler (Dendroica magnolia), demonstrating that Gray Jaysdepredate free-flying birds in addition to nestlings and dead adults. Predation of birds, which was manifested in a recently independent bird, may be a regular […]
SERIES OF NESTS OF THE MAGNOLIA WARBLER.
Magnolia Warbler (Dendroica magnolia) Science Article 2 abstract The warblers were late in 1907. The cold, backward spring was behind time in unfolding catkin and leaf whereon the insect hosts prey, and the warblers who live on the insect life keep pace with the resurrection and birth of moth and butterfly, mosquito and aphis, caterpillar […]
Osmoregulation and adaptive radiation in the ovenbirdgenusCinclodes(Passeriformes: Furnariidae)
Ovenbird (Seiurus aurocapilla) Science Article 7 abstract The genus Cinclodes is unique among passerines because it includes two species thatcan be considered marine/coastal and also includes several species that inhabit freshwaterstreams or that shift habitats between terrestrial/fresh water and marine habitats. The Cinclodes clade satisfies two criteria of an adaptive radiation: it is monophyletic and […]
Evolution of the ovenbird-woodcreeper assemblage (Aves: Furnariidae), major shifts in nest architecture and adaptive radiation
Ovenbird (Seiurus aurocapilla) Science Article 10 abstract The Neotropical ovenbirds (Furnariidae) form an extraordinary morphologically andecologically diverse passerine radiation, which includes many examples of species thatare superficially similar to other passerine birds as a resulting from their adaptations tosimilar lifestyles. The ovenbirds further exhibits a truly remarkable variation in nesttypes, arguably approaching that found in […]

HABITAT FRAGMENTATION AND PAIRING SUCCESS IN THE OVENBIRD (SEIURUS AUROCAPILLUS)
Ovenbird (Seiurus aurocapilla) Science Article 2 abstract In 1990 and 1991, we determined the proportion of Ovenbird (Seiurus aurocapillus)territorial males that were paired in a 25-ha plot in an extensive forest (>350 km 2) inQu6bec, and compared it to pairing success in populations breeding in nearby forest fragments (4.5-53.0h a) in Quebec and Ontario.

FOREST PRODUCTIVITY PREDICTS INVERTEBRATE BIOMASS ANDOVENBIRD (SEIURUS AUROCAPILLUS) REPRODUCTION INAPPALACHIAN LANDSCAPES
Ovenbird (Seiurus aurocapilla) Science Article 1 abstract Forest-floor detrital food webs are sustained by annual inputs of leaf fall.However, it is unknown whether this bottom-up effect extends to vertebrates feeding onthe detrital food web. We hypothesized that reproductive success of Ovenbirds (Seiurusaurocapillus L.) is a function of macroinvertebrate biomass within the detrital food web,and that […]
