Illustrator David Sibley and actor H. Jon Benjamin will face off in the bird illustration battle of the century during BirdNote's Year-end Celebration and Auction!
Field Sparrows make use of all the warm months of the year by building multiple nests each breeding season. Females will build their first, cup-shaped nest near the ground in dense grasses. As shrubs and trees grow their leaves throughout the summer, they will pick new spots higher off the ground each time — to protect their eggs from mammals and snakes. These birds avoid human activity and they’re sensitive to suburban sprawl. We can help conserve field sparrows by conserving brushy habitats in agricultural landscapes.

Field Sparrow Nests Climb Higher and Higher
Written by Conor Gearin
This is BirdNote.
[Field Sparrow song, ML94430, 0:32-0:35]
When a Field Sparrow builds a nest early in spring, dense grasses offer the best cover, so that’s where she builds. But it’s only the first of several nests she’ll make. Later in the season, as shrubs and trees grow their leaves, Field Sparrows nest again and again, higher off the ground each time — to protect their eggs from mammals and snakes.
This multiple nest strategy helps Field Sparrows make use of all the warm months of the year for their breeding season.

Field Sparrows build their cup-shaped nests in fields and in brushy areas, but they avoid human activity and they’re sensitive to suburban sprawl. Conserving brushy habitats in agricultural landscapes will help Field Sparrows keep building their nests higher and higher every summer.
Outside of town, listen for the Field Sparrow’s song, which sounds like a ping-pong ball bouncing and then coming to rest.

And watch for their trick to eat grass seeds: jumping on the end of a grass stalk, riding it to the ground, then chowing down on the seeds. Good eatin’.
