SUPERFAMILY CORVIOIDEA
Family Cracticidae
Family Vireonidae
Family Phasianidae:
Pheasants, Grouse, Turkeys and Chickens
Usually no pair bond
Harem polygamy – sexual dimorphism

Family Numididae
Guinea fowl
African birds
Complex feathers and coloration
15 species
highly social and very diverse
Family Cracidae:
Currasows, Chacalacas, Guans
Neotropical
Female or biparental care
In Brazil, there calls are: female “I want to get married,” male “I want to die”
Currasows have expanded trachea, syrinx is very deep, very low vocals like grunting pig
Very edible family – all critically endangered
True ducks – very diverse
All continents except Antartica
Vary in feeding mode (divers, boppers, fish eaters, shellfish fishers, etc)
Different sizes
Swans – monogamous; swift-tailed ducks polygamous
Duck chicks are precotial, only cared for by 1 sex
Has a phallus
Family Anseranatidae
Magpie Geese
Pied black and white pattern, prominent knob
Semi-webbed feet
Endemic to Australia
Molt – drop all the flight feathers at once and will be flightless for 4-7 weeks (like true ducks)
