Nest destruction elicits indiscriminate con- versus heterospecific brood parasitism in a captive bird
Following nest destruction, the laying of physiologically committed eggs (eggs that are ovulated, yolked, and making their way through the oviduct) in the nests of other birds is considered a viable pathway for the evolution of obligate interspecific brood parasitism. While intraspecific brood parasitism in response to nest predation has been experimentally demonstrated, this pathway has yet to...
متن کاملClouds in Tropical Cyclones
Clouds within the inner regions of tropical cyclones are unlike those anywhere else in the atmosphere. Convective clouds contributing to cyclogenesis have rotational and deep intense updrafts but tend to have relatively weak downdrafts. Within the eyes of mature tropical cyclones, stratus clouds top a boundary layer capped by subsidence. An outward-sloping eyewall cloud is controlled by adjustm...
متن کاملBird Mite Infestation
Mites in the genus Dermanyssus are external parasites of birds, rodents and other mammals. The most common member of this group is the Chicken Mite that infests poultry roosts and wild bird nests. The chicken mite feeds primarily at night when the birds return the nest or roast area. They hide during the day in nearby cracks, crevices and other protected sites. These mites are known to infest h...
متن کاملPrecipitation and Cloud Structure in Midlatitude Cyclones
Composite mean fields and probability distribution functions (PDFs) of rain rate, cloud type and cover, cloud-top temperature, surface wind velocity, and water vapor path (WVP) are constructed using satellite observations of midlatitude cyclones from four oceanic regions (i.e., the North Pacific, South Pacific, North Atlantic, and South Atlantic). Reanalysis surface pressure fields are used to ...
