Interesting Fact: Sometimes creepers build nests in unusual places, such as behind window shutters, in or under roofs, inside fenceposts, or inside concrete blocks. One brought up a family in a specially constructed box made of pieces of Douglas-fir bark. ( https://www.allaboutbirds.org/guide/Brown_Creeper/lifehistory )
Interesting Fact: The Brown Creeper builds a hammock-like nest behind a loosened flap of bark on a dead or dying tree. It wasn’t until 1879 that naturalists discovered this unique nesting strategy. ( https://www.allaboutbirds.org/guide/Brown_Creeper/lifehistory )
What do you call a bunch of chickens playing hide-and-seek?
Interesting Fact: Brown Creepers burn an estimated 4–10 calories (technically, kilocalories) per day, a tiny fraction of a human’s daily intake of about 2,000 kilocalories. By eating a single spider, a creeper gains enough energy to climb nearly 200 feet vertically. ( https://www.allaboutbirds.org/guide/Brown_Creeper/lifehistory )
