An interesting story of a heist – of a rare book, committed by college students.
By one o’clock that afternoon, the 227-year-old liberal-arts college was swarming with campus police, uniformed Lexington Police, plainclothes detectives, and forensic teams, as well as local news crews covering the developing “Transy Book Heist,” a crime that would one day be listed among the F.B.I.’s all-time most significant art-theft cases. From the facts that were available, it appeared that a team of four men, described as Caucasian, in their 20s, had stolen some of the most prized books and manuscripts in the university’s collection, and attacked a librarian in the process. The take could be more than $5 million. The thieves left no fingerprints behind, and there were almost no witnesses.
A photographer in Minnesota recently captured an adorable shot of a Common Merganser followed by dozens of fuzzy babies.
Scientists aren’t sure exactly why ducks do this, but it could effectively serve as a reproductive insurance policy. If a raccoon invades a merganser nest and destroys all the eggs, the female still has more offspring being safely incubated in other nests. “One possibility would be, in a sense, not putting all their eggs in one basket,” Kaufman says.
This behavior doesn’t completely explain Cizek’s photograph, though, because there is a limit to how many eggs one duck can successfully incubate. Female ducks lay about a dozen eggs and can incubate as many as 20, says Kaufman. More than that, and the birds can’t keep all the eggs warm.
We are not the only ones bound by the rules of grammar. Birds are too.
These reactions and non-reactions suggest that tits need syntax to make sense of commands. Rather than telling the flock to mob right away, it’s important to educate the birds on the threat first. Similar grammatical logic has been exhibited in other species like the Carolina Chickadee, says Carrie Branch, a PhD candidate in behavioral ecology at the University of Nevada, who was not involved in the study. Though Suzuki’s work does an excellent job furthering our understanding of bird communication, Branch says, it would also be interesting to see if Willow Tits respond to the same remixes.
