National Geographic's Mallard Ducks.

Since 2004, mallard ducks have been coming to the courtyard of the National Geographic Society headquarters, an urban oasis in downtown Washington, D.C. In spring 2011, a female mallard and her ten newborn ducklings made their home here.

The ducklings stayed close together and were constantly supervised by their mother. National Geographic staff posted signs asking visitors not to feed the birds and to stay at least ten feet from the ducklings to prevent the mother from abandoning her brood.

The path to water was sometimes a slippery slope for the ducklings. The family enjoyed free reign of National Geographic’s courtyard, setting out for frequent swims in the fountain and resting in shady, landscaped areas that were blocked off for their safety.

Ducklings enjoy a swim in the fountain with their mother, who bears all the responsibility for raising them. The father “does stay close by,” Curry said. Two males were spotted visiting the courtyard, but only one appeared to be mature enough to be the ducklings’ father.

Ducklings take a break on a ramp built especially for their easy access to and from the water. “Our Engineering department found the ducks in the water and they couldn’t get out, so they found this piece of stainless steel to make a ramp for them,” Curry said.

Mated mallard pairs migrate to and breed in the northern parts of their range and build nests on the ground or in a protected cavity. Females normally lay about a dozen eggs, and the incubation period lasts just under a month.

Ducklings Eating

Despite a relatively sheltered city upbringing, six of the ducklings were lost, felled by predators, the elements, and other dangers. According to experts, such losses are normal for a brood of this size.
Here, the four remaining ducklings feed from a tray set out in the courtyard. After the mother made an attempt to take her ducklings across a busy intersection one evening, staff members discovered that she had been fed at her nearby nesting site and was trying to return there. In order to keep the ducks from heading into the street, Curry began putting out food for them. City Wild Life, one of the organizations advising the Society on duck care, provided special food that is served in a shallow tray of water, a method that teaches the ducklings how to eat as they would in a pond.
After a particularly busy late April weekend at National Geographic headquarters, the mother duck relocated her four remaining ducklings several blocks away to Lafayette Square, a national park near the White House, where they appear to be adapting quite well.

I like nature, cooking and photography. In my travels between Argentina and Italy I prefer witness through photography environment, natural and gastronomic riches.
