A ‘Gaggle of Geese'. Late evening catch of Canada Geese, Branta canadensis, Grazing and one for sorrow!...a solitary Magpie. Swillington Ings, West Yorkshire.
Many thanks for visiting my Flickr pages ...Your visits, interest, comments and kindness to 'fave' my photos is very much appreciated, Steve.
Canada Geese eat grain from fields, graze on grass, and dabble in shallow water by tipping forward and extending their necks underwater. During much of the year they associate in large flocks, and many of these birds may be related to one another. They mate for life with very low “divorce rates,” and pairs remain together throughout the year. Geese mate “assortatively,” larger birds choosing larger mates and smaller ones choosing smaller mates; in a given pair, the male is usually larger than the female. Most Canada Geese do not breed until their fourth year; less than 10 percent breed as yearlings, and most pair bonds are unstable until birds are at least two or three years old. Extra-pair copulations have been documented.
During spring, pairs break out from flocks and begin defending territories. Spacing of these pairs is variable and depends on availability of nest sites and population density; where population is large, even after a great many fights birds may end up nesting in view of one another, and some populations are semi-colonial.
Canada Goose threat displays may involve head pumping, bill opened with tongue raised, hissing, honking, and vibrating neck feathers. When an intruding goose doesn’t retreat, geese may grab each other by breast or throat and hit each other with their wings. Fighting may result in injuries.
Female selects nest site, builds nest, and incubates eggs. She may brood goslings in cold, wet, or windy weather and while they’re sleeping for first week after hatching. Male guards the nest while female incubates.
Soon after they hatch, goslings begin pecking at small objects, and spend most of their time sleeping and feeding. They remain with their parents constantly, though sometimes “gang broods” form, especially in more southern latitudes. These can include at least two broods, and sometimes five or more, that travel, feed, and loaf together, accompanied by at least one adult.
Young often remain with their parents for their entire first year, especially in the larger subspecies. As summer wanes birds become more social; they may gather in large numbers at food sources; where food is limited and patchy, may compete with displays and fights.
In winter, Geese can remain in northern areas with some open water and food resources even where temperatures are extremely cold. Geese breeding in the northernmost reaches of their range tend to migrate long distances to winter in the more southerly parts of the range, whereas geese breeding in southern Canada and the conterminous United States migrate shorter distances or not at all. Individuals tend to return to the same migratory stopover and wintering areas year after year. Spring migration may be difficult for observers to track because of over-wintering birds and movements between night time resting areas and feeding areas, but the bulk of spring migratory movements tend to move north behind the retreating snow line, where the temperature is averaging 35 degrees.
Migrating flocks generally include loose aggregations of family groups and individuals, in both spring and fall. Flights usually begin at dusk, but may begin anytime of day, and birds fly both night and day. They move in a V formation, with experienced individuals taking turns leading the flock.
