This topic remains contentious ( Box 1), but these declines have been attributed to a multitude of factors, including infectious disease, pollution, pesticide use, predator dynamics, new building methodologies and more efficient grain harvesting and storage ( Shaw et al., 2008 Summers-Smith, 2003 Singh et al., 2013 Bell et al., 2010 Dadam et al., 2019). Though still widespread, significant declines have been reported in the native range of the species since the 1970s. A reliance on humans is evident from their colonization of Northern Europe, Eastern Europe and Central Asia in the early 1800s, as agriculture spread and urbanization increased ( Summers-Smith, 1963). However, they also continue to increase their geographic range by exploiting ongoing and accelerating anthropogenic change ( Ravinet et al., 2018 Saetre et al., 2012). Becoming commensal some 10,000 years ago, house sparrows are now strongly associated with habitats that have been modified by humans. House sparrows are native to parts of Asia, North Africa and most of Europe, (with the exception of Italy which is occupied by the Italian sparrow P. Native distribution and natural range expansions Here, we explore the natural history of house sparrows and the contributions that these birds have made to basic biology and beyond. Their ubiquity and close association with humans have undoubtedly led to their detailed study across biological and even sociological disciplines. It is for this relationship with people that they received their species identifier domesticus, which derives from the Latin domus or 'house', from Carl Linnaeus in 1758 ( Jobling, 2009 Anderson, 2006). ![]() Considered anthrodependent, some populations have gone extinct locally without human presence ( Ravinet et al., 2018 Summers-Smith, 1988). House sparrows can be found living and breeding in climactically extreme environments from deserts in southern California to cities above the Arctic circle, where they are found almost exclusively in close proximity to human habitation ( Hanson et al., 2020b). The species is one of the most widely distributed and common birds in the world, represented by 12 different subspecies ( Summers-Smith, 2009). If you can't raise the baby sparrow on your own, call a local wildlife refuge to pick the bird up and take care of it.House sparrows are small, sexually dimorphic birds in the family Passeridae. Once the bird grows feathers and can fly or move around on its own, release it into the wild. Repeat this feeding and drinking process every 2 hours until the bird isn't interested in the food. Use a clean dropper to carefully pour the cat food mixture into the baby bird’s mouth. ![]() To feed the bird, mix some soft cat food with water. Orphaned birds are often dehydrated, so use a dropper to pour some room temperature water on to the bird’s beak to give it something to drink. If the baby bird doesn’t have feathers, set the box on a heating pad and turn it on to the lowest setting to keep the bird warm. If the mother doesn't come back, put gloves on, carefully scoop the baby bird up, and place it in a cardboard box filled with cloth towels. Look for the mother circling overhead or watching from a distance. If you've found a baby house sparrow outside of its nest, leave it where it is and monitor it for a couple of hours to make sure its mother doesn't come back. Insects such as flies can lead to fatal constipation in a young nestling. If the sparrow is a nestling and not a fledgling, refrain from feeding it any insects and stick to the cat food diet.You could also consider feeding dried insects, as sold for reptiles such as bearded dragons.The black line in a maggot his food in his gut, so wait until this black line disappears before feeding to the baby bird. Again, the maggot should only be fed when its gut is empty. Another option is to offer clean white maggots, as sold by angling shops.Publisher: Blackwell Science Instead, try offering the smallest-sized crickets (available from reptile supply shops). X Research source Practical Wildlife Care. There is something toxic about earthworms that makes captive birds die. Please note, do not give earthworms to captive baby sparrows.Young birds tend to take live food better than dry food. Sparrow natural diet includes dry foods such as buds and seeds, and live food such as spiders, snails, aphids, caterpillars, and other small invertebrates. Add as many bugs as possible to the puppy or cat food. ![]()
