Overwintering is the process by which some organisms pass through or wait out the winter season, or pass through that period of the year when "winter" conditions (cold or sub-zero temperatures, ice, snow, limited food supplies) make normal activity or even survival difficult or near impossible. In some cases "winter" is characterized not ...
In the winter, when many of these birds are migrating, farmers are now flooding their fields in order to provide temporary wetlands for birds to rest and feed before continuing their journey. [146] Rice is a major crop produced along this flyway, and flooded rice paddies have shown to be important areas for at least 169 different bird species ...
Many bird leave for the winter, migrating south to warmer climes. Those that stay avoid the hazards of migration and maintain a year-round territory. Ever wonder how birds stay warm in the winter?
This type of migration is advantageous in birds that, during the winter, remain close to the equator, and also allows the monitoring of the auditory and spatial memory of the bird's brain to remember an optimal site of migration. These birds also have timing mechanisms that provide them with the distance to their destination. [9]
Insect winter ecology describes the overwinter survival strategies of insects, which are in many respects more similar to those of plants than to many other animals, such as mammals and birds. Unlike those animals, which can generate their own heat internally ( endothermic ), insects must rely on external sources to provide their heat ...
Loons can live as long as 30 years and can hold their breath for as long as 90 seconds while underwater. [7] [8] Loons are migratory birds, and in the winter months they move from their northern freshwater lake nesting habitats to southern marine coastlines.
Birds from temperate North America east of the Rocky Mountains migrate to the southern United States and southern British Columbia. It is often a year-round resident where water remains open in winter. The number of birds that stay year-round near the northern limit of the species' range seems to be increasing. [20] [21]
