About These Birds
American Tree Sparrow
The American Tree Sparrow is a compact passerellid weighing 19 g with a 14.4 cm wingspan, breeding in shrubby Arctic tundra and wintering in open fields and weedy areas across North America. It is identified by its rufous cap and distinctive central breast spot.
Bermuda Towhee
The Bermuda Towhee was an extinct towhee species that was endemic to Bermuda. Known from subfossil bones found in cave and marsh deposits, it was likely a ground-dwelling bird that fed on seeds and insects in the island's original cedar and palmetto forests. It became extinct soon after the islands were first colonized in the early 17th century.
