Because of its short wings, it may have been able to fly but probably stayed largely on land.
The structure of its feet and long hind legs indicate an adaptability to water which means it probably searched for food along the shoreline like cranes do.
Their habitation near water also reflects the possibility of early behavioral specialization and long-time aquatic evolution.
Scientists are continuing to figure out why one group of birds survived prehistoric times to develop into modern species while another known set of birds died off with the dinosaurs.

LONDON - JANUARY 22: This handout image, showing an artist's interpretation of the winged dinosaur, Microraptor Gui, was published in the Journal Nature on January 22, 2003 in London, England. Microraptor Gui was discovered by the Institute of Vertebrate Paleontology and Paleoanthropology in Beijing. Scientist believe the four-winged dinosaur, measuring around one meter (red and black bar at bottom left represents five cm) lived approximately 130-million years ago and would have flown in the same way a flying squirrel does today.
