Summer Tanager (Piranga rubra) Science Article 2 abstract A Summer Tanager (Piranga rubra) was observed attempting to eat an anole (Anolis carolinensis) at a migratory stopover site. The event may reflect the importance ofbehavioral plasticity during migration, but might also be the result of a simple stimulus response mechanism. DANIEL FROEHLICH, J.

Breeding Habits, Nestling Development, andVocalizations in the Summer Tanager
Summer Tanager (Piranga rubra) Science Article 3 abstract A pair of Summer Tanagers (Piranga rubra) nested near Zebulon, WakeCounty, N.C., in the spring of 1983. Nest contents were examined almost daily from 21May, the first day of incubation, through fledging of the young on 12 June. ELOISE F. POTTER, The Chat, 1985 Download article download […]
An observation of attempted interspecific kleptoparasitism between two neotropical Tyrannid flycatchers
Sulphury Flycatcher (Tyrannopsis sulphurea) Science Article 1 abstract Kleptoparasitism, the interspecific and intraspecific stealing of already procured food, is well known among many taxa of birds (Brockmann & Barnard 1979), but has been reported only rarely in the avian family Tyrannidae. To my knowledge there are only two published observations of kleptoparasitism by tyrannid flycatchers, […]
SENTINEL BEHAVIOR, SEASONALITY, ANO THE STRUCTUREOF BIRO FLOCKS IN A BRAZlLIAN SAVANNA
Suiriri Flycatcher (Suiriri suiriri) Science Article 1 abstract We investigated composition, annual cycle, site fidelity; foraging behavior of birds in mixed-species flocks, and the importance of sentinel behavior by the White-banded Tanager, Neothraupis fasciata, in a cerrado (savanna) near Brasilia, Brazil. Mixed-species flocks, comprising up to twenty-five resident, migratory, and transitory species, occurred in all […]
Habitat use by Moltoni’s Warbler Sylvia cantillans moltonii in Italy
Subalpine Warbler (Sylvia cantillans) Science Article 1 abstract Moltoni’s Warbler Sylvia cantillans moltonii is a poorly studied bird endemic to a restricted area in the central-western Mediterranean. We analysed selection of different vegetation structural types byMoltoni’sWarblers for singing and foraging in two hilly areas in the northern Apennines (Italy) with low-intensity farming. We related habitat […]

The Relation of Hunting Site Changes to Hunting Success in Green Herons and Green Kingfishers
Striated Heron (Butorides striata) Science Article 1 abstract Considerable information is available on the feeding habits of herons and kingfishers (e.g., Skutch 1957; 1972. Meverriecks 1960. 1966. 1971. Slud 1964. Ienni 1969: Recher and Rechkr 1972, Kushlan 1973,
MOLECULAR SYSTEMATICS, PHYLOGEOGRAPHY, AND POPULATION GENETICSOF XIPHORHYNCHUS (AVES: DENDROCOLAPTIDae) IN THE AMAZON BASIN
Straight-billed Woodcreeper (Xiphorhynchus picus) Science Article 1 abstract Among those few hypotheses amenable to falsification by phylogenetic methods concerning the diversification of the Amazonian biota, three can be singled out because of their verifiable predictions: the riverine barrier, the gradient, and the basal trichotomy hypotheses. I used phylogenetic and population genetics methods to reconstruct the […]
Habitat use by wintering Steller’s Eiders Polysticta stelleri in northern Norway.
Stellers Eider (Polysticta stelleri) Science Article 1 abstract Habitat use of Steller’s Eiders Polysticta stelleri was studied in Varangerfjord, northern Norway, during three winter periods (November, January and April) in 1996/97. We partitioned habitats based on water depth and benthic conditions, and compared the benthic characteristics in known feeding areas to nearby areas avoided by […]
