The design and function of birds' nests
All birds construct nests in which to lay eggs and/or raise offspring. Traditionally, it was thought that natural selection and the requirement to minimize the risk of predation determined the design of completed nests. However, it is becoming increasingly apparent that sexual selection also influences nest design. This is an important development as while species such as bowerbirds build struc...
متن کاملResponses of Birds to Broken Eggs in Their Nests’
We tested the responses of two bird species which nest on unmovable substrates (e.g., cavities and walls) to simulated and actual egg damage in their nest. Tree Swallows (Tachvcineta bicolor) and Barn Swallows (Hit-undo ruiticaj removed broken eggs and continued to incubate the rest of their clutch, but rcsponse times took up to 8 days, and observed rejection rates were lower than reported for ...
متن کاملKnowledge Gained from Video-Monitoring Grassland Passerine Nests
In the mid-1990s, researchers began to adapt miniature cameras to video-record activities :rt cryptic passerine nests in grasslands. In the subsequent decade, use of these video surveillance systems spread dramatically, leading to major strides in our knowledge of nest predation and nesting ecology of many species. Studies using video nest surveillance have helped overturn or substantiate many ...
متن کاملMonitoring Grassland Birds in Nocturnal Migration
We censused vocalizations of night-migrating birds by making continual audio recordings of the night sky from a transect of seven recording stations across New York State in fall 1991-1993 and at one recording station in south Texas in spring 1995. Bird calls on these audio recordings were later detected by human listening and by automatic sound-detection software. Vocalizations of several migr...
