do robins have more than one set of eggs per year
American robin The American robin begins to breed shortly after returning to its summer range. It is one of the first North American bird species to lay eggs, and normally has two to three broods per breeding season, which lasts from April to July.[12]
Common wood pigeon It breeds in trees in woods, parks and gardens, laying two white eggs in a simple stick nest which hatch after 17 to 19 days. Wood pigeons seem to have a preference for trees near roadways and rivers. Males exhibit aggressive behaviour towards each other during the breeding season by jumping and flapping wings at each other. Their plumage becomes much darker, especially the head, during hot summer periods.
