Behavior
The Wood Thrush is primarily solitary, but occasionally forms mixed-species flocks in the winter. Its breeding territory range from 800 to at least 8000 square meters in size, and are used for nesting, gathering nest materials, and foraging. Some Wood Thrushes also defend a feeding territory in the winter. Territorial interactions are usually settled without physical contact, but in high-intensity encounters or nest defense, physical interactions with the feet or bill have been observed. Defense behaviors in response to nest predators include wing flicks, tail flicks, and raising the crest, sometimes escalating to dives and strikes.
This species has also been observed displaying a behavior known as anting. Anting occurs when a bird picks up a single ant or group of ants and rubs them on its feathers. The purpose of this behavior is unknown, but it is thought that the birds may be able to acquire defensive secretions from the ants possibly used for some medicinal purposes, or that it simply supplements the birds' own preen oil.

Famous quotes containing the word behavior:
“Temperament is the natural, inborn style of behavior of each individual. It’s the how of behavior, not the why.... The question is not, “Why does he behave a certain way if he doesn’t get a cookie?” but rather, “When he doesn’t get a cookie, how does he express his displeasure...?” The environment—and your behavior as a parent—can influence temperament and interplay with it, but it is not the cause of temperamental characteristics.”
—Stanley Turecki (20th century)
“Consciousness is cerebral celebrity—nothing more and nothing less. Those contents are conscious that persevere, that monopolize resources long enough to achieve certain typical and “symptomatic” effects—on memory, on the control of behavior and so forth.”
—Daniel Clement Dennett (b. 1942)
“The fact that behavior is “normal,” or consistent with childhood development, does not necessarily make it desirable or acceptable...Undesirable impulses do not have to be embraces as something good in order to be accepted as normal. Neither does children’s behavior that is unacceptable have to be condemned as “bad,” in order to bring it under control.”
—Elaine Heffner (20th century)
