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 […]

Ovenbird response to seismic lines
Ovenbird (Seiurus aurocapilla) Science Article 9 abstract Rapid development of energy reserves in the boreal forest of western Canada hasraised concerns about the potential impacts of forest fragmentation caused by seismic lines. Seismic lines are narrow linear corridors cut by the energy sector to access remote areas. Traditionally, seismic lines were cut using a bulldozer […]
Foraging Ovenbird Follows Armadillo
Ovenbird (Seiurus aurocapilla) Science Article 5 abstract Report an observation of a foraging Ovenbird (Seiurus uurocapiZZus) following a ninebandedarmadillo (Dasypus novemcinctus), near Gainesville, Florida. Close attendance only while the armadillo was moving and disturbing leaf litter suggests the Ovenbird was taking advantage of increased prey availability caused by the armadillo’s flushing of insects Douglas J.

Effects of forest edges on Ovenbird demography in a managed forest landscape.
Ovenbird (Seiurus aurocapilla) Science Article 8 abstract We studied the reproductive ecology of Ovenbirds (Seiurus aurocapillus) for 3 years in a primarily forested landscape in northern Wisconsin. We searched for and monitored nests in large, closed-canopy northern hardwood forests adjacent to recent clearcuts (
