| House
Sparrows in North America are closely linked
to human activity and largely absent from extensive
forests and grasslands. They readily nest in
urban structures and eat urban scraps. They
create large nests relative to their size and
they prefer small, enclosed spaces where they
will use small sticks and line the inside with
grass, string and straw. They mainly eat seeds
and grain but will feed on bread crumbs and
the like when ever possible.
The
fledglings need protein to grow and their diet
mainly consists of insects. House Sparrows are
not migratory but will often take advantage
of warmer roosting sites during winter in urban
environments. They are boisterous birds who
roost in noisy flocks on branches of city trees,
ivy covered walls and under eaves of houses.
