Wing Shape

The shape of a bird's wing is often an indication of its habits and behavior. Fast flying birds have long, pointed wings. Soaring birds have long, broad wings. Different songbirds will have a slightly different wing shape. Some species look so much alike (Empidonax flycatchers) that scientists sometimes use the length of specific feathers to confirm a species' identification.

Fun Facts

Western Field Sparrows tend to be larger, paler, and grayer than eastern birds.

Field Sparrow pairs often divide up a fledged brood for continued care, or the male may take the entire brood so the female can begin a new nest.


The song consists of an accelerating series of whistles, becoming a trill near the end.  A sharp "chip" call is also given.


The Field Sparrow’s nest is a cup of grasses and is lined with finer materials. It is placed on the ground or in a low shrub.

Number: Usually lay 3-5 eggs.
Color: White or pale bluish with darker markings.

Incubation and fledging:
The young hatch at about 10-11 days, and fledge at about 7-8 days, though remaining dependent on the adults for some time.
