Tree Sparrow Passer montanus

This bird is closely related to the House Sparrow and even looks exactly like it. It's also rather identical to the Hedge Sparrow, but the two species are not even closely related to another. The most important differences between the Tree Sparrow and the House Sparrow are the brown cap (the cap of the House Sparrow is grey) and the white ringlike line on the neck, hence the Dutch name Ring Sparrow. One might consider this to be the wild edition of the House Sparrow, for the Tree Sparrow is a bird of the country side. Wherever the House Sparrow is absent, one might find the Tree Sparrow. It's less bound to humans than the House Sparrow, but enough of an opportunist to take whatever food humans might want to offer.

Just like the House Sparrow Tree Sparrows often appear in great numbers. In a group they behave more civilized than House Sparrows do: there is less fighting among one another, less loud arguments. The Tree Sparrow is more cautious than the House Sparrow is. When scared, the whole group disappears at the same time in just one instance.

This bird belongs to the family of Sparrows (Passeridae). It is common in our garden and can be seen in Holland all year round. The bird is 5,5" and weighs 23 grams. It lives in parks, gardens and outskirts mostly. It eats seeds and insects. The sexes do not differ from one another. Nest making starts in April, but sometimes the last nest is not made before the end of july. The bird looks for a hole in a tree to make its nest in. Then four to six eggs are laid, which are looked after for 13 days. The hatchlings take 14 to 15 days to leave the nest.
