‘Monsters University’ Holds Off ‘White House Down’ at Box Office

Pixar Animation Studios/Walt Disney Pictures “Monster’s University.”

LOS ANGELES — Big guns and heavy star power took aim at the weekend film box office, but “Monsters University,” an animated frolic from Disney’s Pixar unit, was still standing when the dust settled. In its second weekend, “Monsters University” had about $46.2 million in North American ticket sales, and about $171 million in domestic sales to date. That put it well ahead of “The Heat,” a heavily armed action comedy starring Melissa McCarhy and Sandra Bullock. “The Heat” placed second with $40 million in weekend sales for 20th Century Fox.

Zombies, guns and Brad Pitt, in Paramount’s “World War Z,” placed third with about $29.8 million in the film’s second weekend; it has had $123.7 million in domestic sales since opening. Roland Emmerich, the master of on-screen disaster, meanwhile had a misfire in “White House Down,” with Channing Tatum and Jamie Foxx in an action thriller about an assault on the White House. The film opened in fourth place, with about $25.7 million in sales for Sony Pictures, placing it well below the openings Mr. Emmerich, its director, posted with apocalypse-themed hits like “2012,” “The Day After Tomorrow,” and “Independence Day.”

Warner’s Superman redo, “Man o! f Steel,” placed fifth in its third weekend, with about $20.8 million in domestic sales, for a total of $248.7 million since opening. In all, the weekend box-office fell about 8.5 percent from the comparable weekend last year — when the comedy “Ted” and Channing Tatum’s “Magic Mike” were on top — to about $192 million from about $209.9 million, according to Hollywood.com.

Ask a Location Scout

The final subject in Metropolitan’s Q. and A. series will be Kevin Breslin, a location scout for television commercials who has arranged thousands of shoots, including the New York Lottery “If I Had a Million Dollars” spots.

Negotiating a Saturday night shoot in Times Square? Check. Shutting down the Brooklyn-Queens Expressway for an early-morning setup? Check. Filming atop the eagles on the 61st floor of the Chrysler Building? That too.

Wondering how he sweet-talks his way into these situations? How he discovers new spots in the city? The craziest place he has ever taken a crew?

Please share your questi ons in the comments section below.

We will pass on the best to Mr. Breslin with some of our own, and publish the answers next week.

Glossy Ibises Are Like 21st-Century Pterodactyls

Along the Atlantic coast, summer afternoons arrive on the wings of the glossy ibis (Plegadis falcinellus). These dark birds seem to appear magically, suddenly haunting shallow mud flats and wet meadows where just minutes earlier none had been.

Johann Schumacher

Even in the velvety late afternoon light, it is hard to call the glossy ibis beautiful. It seems as if every ibis hides an inner dinosaur. Up close, there is something primitive about them, almost vulture-like, and even in flight – where their grace is on display to its greatest visual effect – their long outstretched necks seem to hark back to something more ancient than lovely.

Ibises’ charms are never wasted on children, though, who are generally more familia r with dinosaur books than field guides, and frequently make comments like: “Look, Mommy, a pterodactyl!”

They probably are not far from right, and theories about modern birds’ reptilian ancestry aside, the ibis’s ancient lineage plays nicely against a 21st-century New York City skyline.

Until recently ibises were not a part of this modern landscape. Indeed, for a beginning bird-watcher in the early 1970s, an ibis was a bird of some note, worth a visit to Jamaica Bay in Queens or Pelham Bay in the Bronx. Glossy ibises first arrived in South America from Africa in the mid-19th century. They have been steadily expanding their range northward since. The bird is quite cosmopolitan and can be found in Europe, Asia, Africa and Australia.

In flight, an ibis is easily distinguished from other waders like herons and egrets, as it flies with its neck outstretched, an odd posture that serves to further emphasize its long, down -swept bill.

Johann Schumacher

The birds use their bills as highly effective probing tools, searching the soft mud with their heads bobbing up and down like sewing machines. When the bill hits the bird’s preferred prey (crustaceans, worms, snakes, small fish and mollusks), the unfortunate food item is quickly dispatched with a simple nod of the head. At times, just the tip of a hapless tail remains briefly in view until it, too, is maneuvered down the bird’s long gullet.

At a distance ibises appear to be uniformly dark, which accounts for one of their early common names, black curlew. When observed through binoculars or a spotting scope, however, the birds are a rich chestnut brown, with a greenish or purplish iridescenc e spreading across their shoulders, lower backs and wings. Their interesting behaviors and unusual colors have sold many pairs of binoculars over time, as the bird fascinates many a neophyte bird-watcher.

Glossies have made themselves at home along our shorelines and now breed within New York City. The birds build twig nests in low shrubs on the city’s remote islands, generally in mixed colonies of other long-legged wading birds like egrets and herons. Ibises depend upon soft mud and open water for survival, so come September, the birds can be observed making their way southbound to the Carolinas and beyond, well ahead of fall’s first frosts.
