Autonomous Ground-Based Tracking of Migrating Raptors using Vision
The following paper presents the design and simulation of a system of ground-based stereo cameras to enable the autonomous tracking of migratory raptors in order to facilitate the study of their flight patterns. A number of stations consisting of a camera pair and a processor are set up along the ridge under observation. Each station computes an estimate of the position and velocity of the bird...
متن کاملParrot Nesting in Southeastern Peru: Seasonal Patterns and Keystone Trees
—Parrots that inhabit tropical lowland forests are difficult to study, are poorly known, and little information is available on their nesting habits, making analysis of community-wide nesting patterns difficult. I present nesting records for 15 species of psittacids that co-occur in southeastern Peru. The psittacid breeding season in this area lasted from June to April, with smaller species nes...
متن کاملA Ground-Nesting Galliform’s Response to Thermal Heterogeneity: Implications for Ground-Dwelling Birds
The habitat selection choices that individuals make in response to thermal environments influence both survival and reproduction. Importantly, the way that organisms behaviorally respond to thermal environments depends on the availability and juxtaposition of sites affording tolerable or preferred microclimates. Although, ground nesting birds are especially susceptible to heat extremes across m...
متن کاملWalking Atop the Cliffs
Despite a growing body of descriptive, theoretical and practical knowledge about Information Systems Development (ISD), large-scale information system development and implementation projects still fail in high numbers. The deeper causes of such failures are only partially understood. This study uses an action research approach in which prescriptions and recommendations drawn from research on an...
متن کاملClief and Deciduous Tree Nests of Marbled Murrelets in Southwestern British Columbia Author(s):
We report on nests of radio-marked marbled murrelets (Brachyramphus marmoratus) nesting in unusual habitats in southwestern British Columbia. We found 1 confirmed and 2 probable marbled murrelet nest sites on cliffs. These represent the 1st substantiated accounts of ground nesting in this species south of Alaska. In addition, we found a marbled murrelet nesting in a 130 (?5)-yr-old red alder (A...
