Effects of forest fragment size, nest density, and proximity to edge on the risk of predation to ground-nesting passerine birds
Article Abstract:
A negative correlation has been found between predation rate and forest fragment size for ground-nesting passerine birds and large predator activity went up as forests were more fragmented. Population declines for Neotropical migrant songbirds may relate to large predator activity. Clustering of nests raised predation by larger predators but did not change small predator activity appreciably. Artificial ground nests with quail eggs and clay eggs were used to compare risk of predation relative to forest fragments size, proximity of the nest to the forest edge and density of nests. Small predators can seldom damage or take quail eggs. Large predators are indicated when the eggs are gone. On fake eggs small predators leave identifiable marks.

Woodpeckers as indicators of forest bird diversity
Article Abstract:
Studies done on the usefulness of woodpecker species in predicting the diversity of other forest bird species using the Polish Ornithological Atlas data on species distribution in Poland are presented. A positive relationship between woodpecker species richness and the number of species of other forest birds were observed and the results demonstrate the suitability of the woodpecker group as part of an indicator system for assessing avian diversity at the landscape scale.

A Multiscale Method for Selecting Indicator Species and Priority Conservation Areas: a Case Study for Broadleaved Forests in Lombardy, Italy
Article Abstract:
Site selection is modeled using edge effect, patch size, isolation, and habitat structure for forest bird conservation. Its use for other taxa and ecosystems is also discussed.
