|House Sparrow - Male|
House Sparrows are a unique species and have several behavioural traits which set them up for success as an introduced species. They prefer to live near human habitation. This provides food and nesting sites and some protection from predators. They are an active, aggressive species and can successfully compete for food and nesting sites with native species. They nest before our native species arrive back in the spring so have their preference of nesting sites. They have 2 or 3 batches per year of up to 5 offspring each. These traits lead to rapid population increases.
|House Sparrow - Female|
The range of this species covers all of North America and Mexico and extending northward into Labrador and Northwest Territories. I was surprised recently to see pictures of them thriving in Churchill, MB. Having Eurasian distribution, they are native to Britain, Scandinavia, Siberia, northern Africa, Arabia, India and Burma. Because of introductions by humans they have become established worldwide almost everywhere except Antarctica. Because of this their population is extremely large. In Europe alone their population is estimated to be 270 million.
