The Eurasian sparrowhawk is found throughout the temperate and subtropical parts of the Old World; whilst birds from the northern parts of the range migrate south for winter, their southern counterparts remain resident or make dispersive movements. Eurasian sparrowhawks breed in suitable woodland of any type, with the nest, measuring up to 60 ...
Most house sparrows do not move more than a few kilometres during their lifetimes. However, limited migration occurs in all regions. Some young birds disperse long distances, especially on coasts, and mountain birds move to lower elevations in winter. [102] [127] [128] Two subspecies, P. d. bactrianus and P. d. parkini, are predominantly ...
The black sparrowhawk is one of the world's largest hawks, only the Henst's, Meyer's and Eurasian goshawk can match or exceed its size. As is common in the genus Astur, male black sparrowhawks are smaller than females. Typically the weights of males lie between 450 and 650 g (0.99 and 1.43 lb) while that of females lies in the 750 to 1,020 g (1 ...
Kestrels occasionally nest in holes created by large woodpeckers, [50] or use the abandoned nests of other birds, such as red-tailed hawks, merlins, and crows. [51] They have been recorded nesting on cliff ledges and building tops, as well as in abandoned cavities in cactuses. [52] [40] American kestrels also commonly utilize nesting boxes. [53]
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 ...

Harris's sparrow has lived for up to 11 years and 8 months in the wild. Predators on the nest can including varied terrestrial mammals, including Arctic ground squirrels (Spermophilus parryii) and stoats (Mustela erminea). [13] Harris's sparrows provide an easy target for these predators due to the location of their nests on the ground.
They eat mainly insects and seeds. Birds in salt marshes may also eat small crustaceans. They nest either in a sheltered location on the ground or in trees or shrubs. Song sparrows with areas of shrub cover in their territory, away from the intertidal coastline, have greater over-winter survival, as well as higher reproductive success. [6]
