From Wikipedia, the free encyclopedia

The Tree Sparrow is 12.514 cm (55 in) long, with a wingspan of about 21 cm (8.25 in) and a weight of 24 g (0.86 oz), making it roughly 10% smaller than the House Sparrow. The adult's crown and nape are rich chestnut, and there is a kidney-shaped black ear patch on each pure white cheek; the chin, throat, and the area between the bill and throat are black. The upperparts are light brown, streaked with black, and the brown wings have two distinct narrow white bars. The legs are pale brown, and the bill is lead-blue in summer, becoming almost black in winter.
This sparrow is distinctive even within its genus in that it has no plumage differences between the sexes; the juvenile also resembles the adult, although the colours tend to be duller. Its contrasting face pattern makes this species easily identifiable in all plumages;the smaller size and brown, not grey, crown are additional differences from the male House Sparrow.Adult and juvenile Tree Sparrows undergo a slow complete moult in the autumn, and show an increase in body mass despite a reduction in stored fat. The change in mass is due to an increase in blood volume to support active feather growth, and a generally higher water content in the body.
The Tree Sparrow has no true song, but its vocalisations include an excited series of tschip calls given by unpaired or courting males. Other monosyllabic chirps are used in social contacts, and the flight call is a harsh teck. A study comparing the vocalisations of the introduced Missouri population with those of birds from Germany showed that the US birds had fewer shared syllable types (memes) and more structure within the population than the European sparrows. This may have resulted from the small size of the founding North American population and a consequent loss of genetic diversity.

Hello Razvan.

A cute picture of this sparrow.
Nice colors and well composed against a nice and quiet background.

Very well done.

Hello Razvan,
Nice capture of Tree Sparrow on a rock. The colours of the OOF natural BG and the lichens on the rock make this a well composed attractive image.
Thanks and kind regards,
Ivan
