Crows Never Forget a Face, It Seems/BCrows and their relatives among them ravens, magpies and jays are renowned for their intelligence and f

2、or their ability to flourish in human-dominated landscapes. That ability may have to do with cross-species social skills. In the Seattle area, where rapid suburban growth has attracted a thriving crow population, researchers have found that the birds can recognize individual human faces.John M. Marz

3、luff, a wildlife biologist at the University of Washington, has studied crows and ravens for more than 20 years and has long wondered if the birds could identify individual researchers. Previously trapped birds seemed more wary of particular scientists, and often were harder to catch. “I thought, We

4、ll, its an annoyance, but its not really hampering our work, “Dr. Marzluff said, “But then I thought we should test it directly.“To test the birds recognition of faces separately from that of clothing, gait and other individual human characteristics, Dr.Marzluff and two students wore rubber masks. H

6、the masks on campus, this time walking prescribed routes and not bothering crows.The crows had not forgotten. They scolded people in the dangerous mask significantly more than they did before they were trapped, even when the mask was disguised with a hat or worn upside down. The neutral mask provoke

7、d little reaction. The effect has not only persisted, but also multiplied over the past two years. Wearing the dangerous mask on one recent walk through campus, Dr. Marzluff said, he was scolded by 47 of the 53 crows he encountered, many more than had experienced or witnessed the initial trapping. T

8、he researchers hypothesize that crows learn to recognize threatening humans from both parents and others in their flock.After their experiments on campus, Dr.Marzluff and his students tested the effect with more realistic masks. Using a half-dozen students as models, they enlisted a professional mas

The researchers then gave a mix of neutral and dangerous masks to volunteer observers who, unaware of the masks histories, wore them at the trapping sites and recorded the crows responses.The reaction to on

10、e of the dangerous masks was “quite spectacular,“ said one volunteer, Bill Pochmerski, a retired telephone company manager who lives near Snohomish, Wash. “The birds were really raucous, screaming persistently,“ he said, “And it was clear they werent upset about something in general. They were upset

11、 with me.“Again, crows were significantly more likely to scold observers who wore a dangerous mask, and when confronted simultaneously by observers in dangerous and neutral masks, the birds almost unerringly chose to persecute the dangerous face. In downtown Seattle, where most passersby ignore crow

12、s, angry birds nearly touched their human foes. In rural areas, where crows are more likely to be viewed as noisy “flying rats“ and shot, the birds expressed their displeasure from a distance.Though Dr.Marzluffs is the first formal study of human face recognition in wild birds, his preliminary findi

McGowan, an ornithologist at the Cornell Laboratory of Ornithology who has trapped and banded crows in upstate New York for 20 years, said he was regularly followed by birds who have benefited from his handouts of peanuts and harassed by others he has trapped in the past.Why cr

16、ows and similar species are so closely attuned to humans is a matter of debate. Bernd Heinrich, a professor emeritus at the University of Vermont known for his books on raven behavior, suggested that crows apparent ability to distinguish among human faces is a “byproduct of their acuity,“ an outgrow

17、th of their unusually keen ability to recognize one another, even after many months of separation.Dr. McGowan and Dr.Marzluff believe that this ability gives crows and their brethren an evolutionary edge. “If you can learn who to avoid and who to seek out, thats a lot easier than continually getting

You remember that Ive mentioned that its important to read the U(36) /U poems aloud, so you can develop an appreci

39、ation of the sounds of the poetry: the rhymes, the U(37) /U , the repetition of words or sounds, and to get a sense of the interplay between the sounds of the words and their meaning.This is really U(38) /U as we move into modern poetry, especially by writers who place so much importance on sounds t

40、hat the meaning becomes all letter-relevant. Like this line by Gertrude Stein that Id like to U(39) /U . Listen as I say the words. “Rose is a rose is a rose is a rose. “ U(40) /U literally, this would seem to be an empty statement, one which gives us no information. But the purpose of a poem need n

41、ot be to inform the reader of anything, but rather to evoke feelings. To create a sensual as well as phonically U(41) /U experience. Now Gertrude Stein was better known for her prose than for her poems. But Id like to quote this line, because of its musicality, and because I think it helps open up o

42、ur U(42) /U to the unconventional style of U(43) /U poets. Youll see this in your homework tonight as you read the poetry of John Ashbery, U(44) /U , which I recommend you do. Poets like Ashbery dont rely so much on any formal rhyme scheme or meter as on the musical quality of the individual words t

43、hemselves. As I said, U(45) /U And now Id like to touch briefly on her essay entitled “Convention and Explanation“.

44、owing passage./BVegetarianism is the theory or practice of living solely upon vegetables, fruits, grains, and nutswith or without the U(47) /U of milk products and eggs generally for ethical, environmental or U(48) /U reasons. All forms of flesh (meat, fowl, and seafood) are U(49) /Ufrom all vegetar

45、ian diets, but many vegetarians use milk and milk products.In the early 21st century, vegetarianism has become decidedly mainstream. The number of vegetarians is difficult to determine, but a 2006 U(50) /U of 1,000 U.S. adults by the Vegetarian Resource Group found that 6.7 percent of respondents ne

46、ver ate meat, and 1.4 percent of those were vegan. A British survey the same year found that 12 percent of respondents called themselves “vegetarian“.
