About These Birds

Baird's Junco

The Baird's Junco is a Near Threatened junco endemic to the mountains of the Sierra de la Laguna in Baja California Sur, Mexico, weighing about 17.85g with a wingspan of 15.5cm. It inhabits pine-oak forest at high elevations and feeds on seeds and insects on or near the ground. Its very restricted range makes it vulnerable to climate change.

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.
