taking a walk towards the outskirts of the city can be very rewarding - there are some beautiful sites to see with so much nature in the region herons flock to the area and viewing their daily flights to and from the mangrove is a true spectacle. 

the best time to witness the beauty and elegance of the herons is between 5pm and 6.45pm when they leave búzios and fly to the swamp to sleep, a special place named dormitório das garças.

there are several local campaigns to protect the birds and the mangrove amid reports that the area is to be turned into a landfill site - the mangrove is not only vital for the herons, but other species of stunning wildlife and plants.
