In a Spanish study, boxes made from a mixture of wood and concrete (woodcrete) had a much higher occupancy rate than wooden boxes (76.5% versus 33.5%), and birds nesting in woodcrete sites had earlier clutches, a shorter incubation period and more breeding attempts per season. This sparrow breeds over most of temperate Eurasia and Southeast Asia, where it is known as the tree sparrow, and it has been introduced elsewhere including the United States, where it is known as the Eurasian tree sparrow or German sparrow to differentiate it from the native unrelated American tree sparrow. 110 Commercial St As with other small birds, infection by parasites and diseases, and predation by birds of prey take their toll, and the typical life span is about two years. [16] The Eurasian tree sparrow's common name is given because of its preference of tree holes for nesting. A study showed increased distance between shelter and a food supply meant that birds visited a feeder in smaller flocks, spent less time on it and were more vigilant when far from shelter. Read on for a few other distinguishing features between the species. [78], The Eurasian tree sparrow has long been depicted in Chinese and Japanese art, often on a plant spray or in a flying flock,[77] and representations by oriental artists including Hiroshige have featured on the postage stamps of Antigua and Barbuda, Central African Republic, China, and the Gambia. [26], Chairman Mao Zedong of China attempted in April 1958 to reduce crop damage by Eurasian tree sparrows, estimated at 4.5 kg (9.9 lb) of grain per bird each year, by mobilising millions of people and many scarecrows to drive the birds to death by exhaustion. Nesting. Whilst these birds are rarer than they used to be, they can still be seen throughout the year across many parts of Scotland. The preferred locations for the autumn display are old Eurasian tree sparrow nests, particularly those where nestlings had hatched. The Tree Sparrow lives in open woodland, orchards and hedgerows and so feeds mostly on seeds of grasses, weeds and cereals, such as barley and wheat. Unlike its relative, the House Sparrow, it is not a bird of cities, instead using farms and lightly wooded residential areas. [36], The male calls from near the nest site in spring to proclaim ownership and attract a mate. The simplest way to tell the difference between house sparrows and tree sparrows is to look at their crown! They also have a larger black throat patch and a gray (not rusty) crown. If you continue to use this site we will assume that you are happy with it. These small finch-like birds have the unfortunate tendency of often being grouped in the “little brown bird” category, but whilst they may not be adorned with the brightest of colours, there are several easy ways to distinguish them. Let’s look at how you tell the difference between a house sparrow vs tree sparrow. Ship-carried birds colonised Borneo. Most nest in cavities but some may nest in bushes or trees, building untidy nests of grass and assorted rubbish. They will visit bird tables for seed. [12][13] The Eurasian species is not closely related to the American tree sparrow (Spizelloides arborea), which is in a different family, the New World sparrows. The Eurasian tree sparrow's extensive range and large population ensure that it is not endangered globally, but there have been large declines in western European populations, in part due to changes in farming practices involving increased use of herbicides and loss of winter stubble fields. [79] The fluttering of the bird gave rise to a traditional Japanese dance, the Suzume Odori, developed in Sendai, which was depicted by artists such as Hokusai. Most species in the genus are typically 10–20 cm (3.9–7.9 in) long, predominantly brown or greyish birds with short square tails and stubby conical beaks. The shipment included 12 hardy Eurasian Tree Sparrows. [3], The Eurasian tree sparrow has a large range estimated as 98.3 million square kilometres (38.0 million sq mi) and a population of 190–310 million individuals. [5][18], The Eurasian tree sparrow's natural breeding range comprises most of temperate Europe and Asia south of about latitude 68°N (north of this the summers are too cold, with July average temperatures below 12 °C) and through Southeast Asia to Java and Bali. Russet Sparrow's name in Japanese is "ニュウナイスズメ". [22] These sparrows are descended from 12 birds imported from Germany and released in late April 1870 as part of a project to enhance the native North American avifauna. Slightly smaller than House Sparrow with entirely rufous cap, black and white cheek, and limited black in the throat. Empty nest boxes, and sites used by house sparrows or other hole nesting birds, such as tits, pied flycatchers or common redstarts, are rarely used for the autumn display. Once very common birds, both species have suffered significant declines in recent decades and as such, both appear on the UK Red List of Birds of Conservation Concern. [51], Predators of the Eurasian tree sparrow include a variety of accipiters, falcons and owls, such as the Eurasian sparrowhawk,[48] common kestrel,[52] little owl,[53][54] and sometimes long-eared owl and white stork. Let’s look at how you tell the difference between a house sparrow vs tree sparrow. Within its limited US range of about 22,000 square kilometres (8,500 sq mi),[23] the Eurasian tree sparrow has to compete with the house sparrow in urban centres, and is therefore mainly found in parks, farms and rural woods. The sexes are similarly plumaged, and young birds are a duller version of the adult. [31] Roof cavities in houses may be used,[31] and in the tropics, the crown of a palm tree or the ceiling of a verandah can serve as a nest site. [76] The large decline in Eurasian tree sparrow numbers is probably the result of agricultural intensification and specialisation, particularly the increased use of herbicides and a trend towards autumn-sown crops (at the expense of spring-sown crops that produce stubble fields in winter). [45][46][47] A wild hybridisation with the resident sparrows of Malta, which are intermediate between the Spanish sparrow (P. hispaniolensis) and Italian sparrows (P. italiae), was recorded in Malta in 1975. This sparrow has occurred as a natural vagrant to Gibraltar, Tunisia, Algeria, Egypt, Israel, the United Arab Emirates,[5] Morocco and Iceland. Typically found in small flocks, often in more natural areas than concrete-loving House Sparrow. Although initially successful, the "Four pests campaign" had overlooked the numbers of locusts and other insect pests consumed by the birds, and crop yields fell, exacerbating a famine which led to the deaths of 30 million people between 1959 and 1961.
