Signs of Peacocks in Trees Peacocks cause problems when they're allowed to roam around residential neighborhoods. Property owners may spot colorful male peacocks or plainer, smaller peahens in yards, on cars, or especially in trees. The birds are drawn to tall foliage for shade and shelter, settling in groups on the branches of ornamental lawn trees. They may also roost on rooftops. People with peacock in festations will notice their extremely loud, shrieking calls in the morning and late into the evening. Damage The large birds are aggressive year-round, but become especially territorial during mating seaso n from April to September. When approached, they use their sharp beaks and tough feet to kick, bite, peck, or scratch humans and pets. Peacocks that land on top of homes also harm roofing or skylights. Cars suffer damage when the birds scratch at shiny windows or paint, mistaking their reflections for rivals. Additionally, peafowl tear up gardens and lawns searching for food. Prevention & Removal Wrapping trunks in bird netting can reduce the possibility of finding peacocks in trees. However, avoid approaching or handling peafowl as they will attack if they feel threatened. Contact wildlife specialists to remove peacocks from trees or anywhere else on your property.
