I believe they are Egyptian geese.

Thank you! It was driving me crazy trying to figure out what birds they are! I think you are correct.

Here is a really good picture of them.

They are pretty birds:)

Had to look these guys up - interesting- apparently a shelduck:
a cross between a goose & a duck...

Range and Habitat

Egyptian Geese are mainly found south of the Sahara in Africa, along the Nile River Valley, and in southern Israel. They were introduced into England in the 1700âÂÂs, and some feral birds can be found in the United States. They are usually found inland, close to wet areas, and can sometimes be found on the open plains.

Behavior

The Egyptian Geese are terrestrial; they spend a lot of time ashore. They feed both day and night sometimes far from the water. They are good swimmers and divers, but do not filter their food. They mainly eat seeds, leaves, grass, berries, and herbs. They also eat locusts, worms, insects, and small animals. They can be real pests when they visit cultivated areas in the dry season, causing real damage to crops. They will perch in trees and on buildings, often returning to the same spot each night to roost.

Egyptian Geese are notoriously bad-tempered especially during breeding season. They are quarrelsome and aggressive, very intolerant of other birds, including their own kind. They can even be vicious. The males hiss and the females make a cackling noise.

Man and climate are creating some interesting population changes in animals. The past few years the Mexican Tree ducks, or Pee-chee-chee-nee ducks, have been becoming more and more commonplace in the Villages and according to my In-Laws they weren't there 4-5 years ago. Wood Storks and Brown Pelicans are showing up more too. While I can not comment on how long they've been here since this is only our third year, it seems that each year we get more and more White Ibises... Ibisi? Cruising our yard in the Spring looking for grubs.

Yeah, we started seeing the Egyptian geese in the central Pembroke Pines area in small numbers about 5-6 years ago. Now they are quite common throughout Weston, Davie, SW Ranches, Miramar too - as far as I can tell.
