Constant density and stable territoriality in some tropical insectivorous birds
Oecologia, 1986Four species of understory antbirds (Formicariidae: Myrmotherula fulviventris, M. axillaris, Microrhopias quixensis, and Thamnophilus punctatus) had stable populations over eight rainy seasons on Barro Colorado Island, Panama. The co-defended territories of M.

Carotenoid Composition of Invertebrates Consumed by Two Insectivorous Bird Species
Journal of Chemical Ecology, 2010Dietary carotenoids are important pigments, antioxidants, and immune-stimulants for birds. Despite recent interest in carotenoids in bird ecology, we know surprisingly little about the carotenoid content of invertebrates consumed by birds. We compared carotenoid (lutein, beta-carotene, and total) concentrations in invertebrates brought to nestlings by ...

Cascading effects of insectivorous birds and bats in tropical coffee plantations
Ecology, 2014The loss of apex predators is known to have reverberating consequences for ecosystems, but how changes in broader predator assemblages affect vital ecosystem functions and services is largely unknown. Predators and their prey form complex interaction networks, in which predators consume not only herbivores but also other predators.

Winter predation by insectivorous birds and consequences for arthropods and plants in summer
Oecologia, 2012Top-down effects of predators can have important consequences for ecosystems. Insectivorous birds frequently have strong predation effects on herbivores and other arthropods, as well as indirect effects on herbivores' host plants. Diet studies have shown that birds in temperate ecosystems consume arthropods in winter as well as in summer, but ...

THE ROLE OF INSECTIVOROUS BIRDS IN PEST MANAGEMENT: A REVIEW
Plant ArchivesInsectivorous and omnivorous birds play a crucial role in agricultural pest management by naturally regulating insect populations. This review explores their ecological functions, sensory ecology, and their potential for integration into Integrated Pest Management (IPM) strategies.

Wildlife Research, 1990
The effectiveness of stomach flushing as a method for determining diet was tested experimentally on captive white-fronted chats, Ephthianura albifrons. The relative retrieval rates of six taxa of prey depended on their size and the durability of identifiable parts. For Scatella sp. (Diptera), flushing was best performed 15 min after ingestion.

The foods of insectivorous birds at Kowhai Bush, Kaikoura
19892 ABSTRACT This study was designed to test a new method for researching the foods of passerine birds. The study site was located at Kowhai Bush, near Kaikoura, and consisted of successional Kanuka forest with little undergrowth. A grid system was used and most native birds were colour banded for the study.
