Distribution

South American from Columbia and Ecuador to south central Brazil (CLO).

Habitat

Lakes, freshwater lagoons, tropical wet savannas, river banks (CLO 2010).


Migration

Non-migratory


Diet 

Herbivorous


Foraging Behavior

Grazing and digging with grazing being the most commonly used tactic (CLO 2010). Juveniles' diets are thought to be comprised primarily of insects (PB 2011).


Reproduction

Horned Screamers are monogomous and are thought to pair for several years to life. They do not have a specific breeding season and is the only screamer species known to have a courtship display. The display consists of the male circling and bowing n front of the female. Large nests are built in or near a marsh and are partially submerged in shallow water. Clutch size varies from 2 to 8 precocial young and both sexes show parental care (CLO 2010; PB 2011).

Habitat

Coastal areas in swamps, marshes, and wet grasslands (PB 2011)

Migration

Diet

Herbivorous. Consists mainly of seeds, bulbs, dry grasses, and wild rice (PB 2011). 
 

Foraging Behavior 

Adults will actively graze and forage. Parents will help chicks to feed by bending tall vegetation to be within reach (PB 2011)
 

Reproduction

Magpie geese are polygynous and usually breed in groups of 3: 1 male and 2 related females. Sexual maturity is reached at about 2 years of age. They breed in floodplains at the end of the wet season from February to June. Their clutch size varies from 3 to 8 eggs and parental care is shared between males and females (Wilbur 2008).

Distribution


North American and Northern Central America 

Map. "Range Map". www.allaboutbirds.org 5 March. 2013. <http://www.allaboutbirds.org/guide/Rosss_Goose/lifehistory>


Habitat


Nesting habitat is on low tundra, marshes an ponds. Winters in agricultural fields, marshes, and shallow lakes (Ryder and Alisauskas 1994; PB 2013).

Migration


Migratory. Winters in the Sacramento Valley of California as well as New Mexico and along the Gulf Coast. (PB 2013).

Diet


Vegetarian. Ross' geese feed on grasses, sedges, and grains (PB 2013).

Foraging Behavior


Ground forager (Ryder and Alisauskas 1994).

Reproduction


Colonial breeder that typically breeds for the first time in their second or third year. The female builds a nest out of leaves, grass, an moss on an island or shore of a tundra lake. She lays  a clutch of 2 - 6 eggs and does 100% of the incubating while the male in the pair stands guard for the entire incubation period of about 3 weeks. Precocial young leave the nest within 24 hours and fledge at 40 - 45 days of age (Ryder and Alisauskas 1994; PB 2013).

Order: Anseriformes
Family: Anatidae
Tribe: Anserini
Halliday, Michael. "Emperor Goose". Photo. http://www.treknature.com 13 March. 2005. 5 March. 2013 <http://www.treknature.com/gallery/photo10881.htm>.

Distribution

 Western Alaska and Northeast Siberia (PB 2013).

Map. "Range Map". www.allaboutbirds.org 5 March. 2013. <http://www.allaboutbirds.org/guide/emperor_goose/lifehistory>

Habitat


Emperor geese winter along the coast on rocky shores and mudflats. The spend the summer further inland on the tundra near a lake or riverbed (Brown 2011; PB 2013).

Migration


Migratory. Timing of migration is affected by the weather. Flocks stage on the north shore of the Alaskan Peninsula before moving to their breeding grounds on the Seward Peninsula, St. Lawrence Island, and Siberia from late May to early June. The geese make the reverse route back in late August and early September. They arrive back on the Aleutians by late November (Brown 2011; PB 2013).

Diet


Omnivorous. Emperor geese feed mostly on plant material while on the breeding grounds. During migration and winter they feed on bivalves and marine algae (PB 2013).

Foraging Behavior


Forages on land while on the breeding grounds and on exposed mudflats during migraton and winter (PB 2013).

Reproduction



Emperor geese are monogomous and mate for life. Pairs are formed by the time they reach the breeding grounds. Females begin building nests immediately upon arrival and the first eggs are laid within 10 days. Clutch sizes ranges from 3 - 8 and the females incubate for approximately 25 days. Parental care of the precocial young is shared. Goslings fledge after 50 - 60 days (Brown 2011; PB 2013).

Bar-headed Goose

(Anser indicus)
Order: Anseriformes
Family: Anatidae
Tribe: Anserini 
Peiker, E.J.. "Bar-headedGoose". Photo. http://www.ejphoto.com 29 Feb. 2012. 12 March. 2013 <http://www.ejphoto.com/barheaded_goose_page.htm>.

 Distribution

Central Eurasia (PB 2013).

Map. "Bar-headed Goose Distribution Map". www.groms.de. 2002. 12 March 2013 <http://www.planetofbirds.com/anseriformes-anatidae-bar-headed-goose-anser-indicus>

Habitat

High elevations. Bar-headed geese winter on mountain grasslands and surrounding crop fields and summer on high altitude lakes (Cucinello 2013; PB 2013).


Migration

Migratory. These birds make two passes over the Himalayas a year at altitudes of up to 9,000 m. The first pass is made on the way to their wintering grounds in northern India, then back again to summer in Western China, Mongolia, and on the Tibetan-Qinghai Plateau (Cucinello 2013; PB 2013).


Diet

Herbivorous, feeding primarily on grasses and grains (Cucinello 2013).


Foraging Behavior

Graze on grasses around lakes and streams where they nest. During the rest of the year, they forage on agricultural grains (Cucinello 2013).


Reproduction

Bar-headed geese are monogamous and pair for several years. If the population is biased towards females then a monogamous pair will accept secondary females and adopt a polygynous mating system. Nesting takes place in the open around lakes and nests are typically a shallow depression in the substrate. The average clutch size is 3 - 8 eggs and nests are defended by females against lower ranking females that may attempt brood parasitism. Parental care is shared and goslings fledge at about 50 days of age. Maturity is reached at about 3 years (Cucinello 2013; PB 2013).

Nest are shallow depression lined with down usually located far away from water in burrows or holes in sand or clay banks. Have also been known to nest in abandoned buildings and hollow trees. Eggs are laid from mid-March to early May and clutch size ranges from 6 to 12. Young fledge after about 55 days (PB 2011; BLI 2013).

The nest is a shallow depression built by the female, made of grass and twigs, lined with down, and is located amongst short vegetation and near water. Clutch size varies from 6 to 10 eggs. Pairs dissolve shortly after incubation begins and the female tends to the eggs and young  until they fledge between 38 and 52 days (PB 2011).
