AN OBSERVATION OF A SUMMER TANAGER ATTEMPTING TO EAT AN ANOLIS LIZARD
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. Field Ornithol., 66(4):501-502, […]
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 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 […]
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 […]
Spring migration of the Garden Warbler (Sylvia borin)across the Mediterranean Sea
Spectacled Warbler (Sylvia conspicillata) Science Article 1 abstract Information concerning the strategy adopted by passerine migrants in crossing ecologicalbarriers is still scant, especially as far as spring migration is concerned. With the aim ofinvestigating the pattern of desert and sea crossing in spring, capture frequency, biometryand physical conditions of Garden Warblers ringed at 18 stations […]
OBSERVATIONS ON THE NESTING OF SPOT-BACKED ANTBIRD(HYLOPHYLAX NaeVIA) IN EASTERN ECUADOR
Spot-backed Antbird (Hylophylax naevius) Science Article 1 abstract Hylophylax antbirds are a small genus of plump, short-tailed antbirds ranging fromHonduras to northern Bolivia, generally below 1100 m elevation, and often associatedwith ant swarms (Hilty & Brown 1989, Ridgely & Tudor 1994, del Hoyo et al. 2003).

Female starlings adjust primary sex ratio in response to aromatic plants in the nest
Spotless Starling (Sturnus unicolor) Science Article 1 abstract Adjustment of offspring sex ratios should be favoured by natural selection when parents are capable of facultatively altering brood sex ratios and of recognizing the circumstances that predict the probable fitness benefit of producing sons and daughters. Although experimental studies have shown that female birds may adjust […]
