Canada Geese pair for life and usually have 5-8 young. One pair at a small pond in Brighton, Michigan, are raising 22 in what is called a “creche.” This happens in areas with large goose populations because, for the first 2-3 weeks, parents cannot recognize their own young. Goslings are unable to recognize their own parents for 5-6 weeks. Consequently, goslings end up in nearby broods parented by one adult pair who, apparently, never bother to count the kids in their care. Here’s a troop of 40 in England!
The geese are so abundant in Brighton they are a nuisance. My dad once told me that these geese are the only animals on the planet that can poop more than they eat! They are walking, honking poop machines. It makes for very green grass but the bacteria in their droppings is a concern. The public also feeds them so many stick around all year instead of migrating. In addition to this bunch, there are two other broods on this pond for a total of 40 goslings and seven adults.
