行为
Brown falcons and other Australian firehawks have been said to pick up sticks with flames and dropping them to spread fires and prey on escaping animals. According to Audubon, "That anecdotal evidence is sourced from personal testimonies by Australian firefighters and aboriginal people, as well as historical literature, and amounts to 14 firsthand narratives of this specific occurrence."

Golden-cheeked Woodpecker
Melanerpes chrysogenys
Common in tropical lowlands of west Mexico, where it is endemic. Found in woodlands, coconut plantations, gardens, and semi-open areas with taller trees, including towns and villages. Often noisy and conspicuous; calls include a sneezy "cháco cháco." Golden wash to cheeks is inconspicuous, but big black eye patch is diagnostic among similar "ladder-backed" woodpeckers. Male has flame-red crown patch and female has pale grayish crown.

Fox Sparrow
Passerella iliaca
Large, dark sparrow with extensive geographic variation. Larger than Song Sparrow, and generally darker with thicker streaking. Four groups of subspecies: Red (only subspecies found in eastern U.S., but breeds to Alaska), Slate-colored (Rockies), Sooty (Pacific Northwest), Thick-billed (California). Habitat varies across range, but generally breeds in forests with thick understory, often with plenty of conifers. In winter, tends to occur in dense thickets. Forages mainly on the ground in search of seeds. Visits feeders.

Chestnut-vented Warbler
Curruca subcoerulea
Distinctive gray bird with a pale eye, streaked throat, rufous vent, and large white patches on the tail. Found in a variety of habitats with thick shrubs, including fynbos, karoo, semi-desert, and savanna. A fairly skulking species that is usually detected by voice: an exuberant mixture of ratcheting notes, chatters, and whistles. Similar to Layard’s Warbler, but easily distinguished by rufous vent and more heavily streaked throat.
