You can find a variety of humane bird repellent sprays online and at home improvement stores. However, if you want to try a DIY method that will keep birds away without harming them, mix some water, dish soap, and a few drops of peppermint oil and spray the area you want bird-free. Peppermint oil is a notoriously lovely smell for humans, but birds tend to avoid it.

Woodpeckers peck at the break of dawn and take a break whenever the sun is not shining. On sunny days, expect pecking from dawn to dusk. On cloudy days, expect sporadic pecking when the sun peeks through. These birds are most active in the spring; you’ll hear them drumming as soon as the weather turns warm. 

Fake owls are a common goose deterrent decoy and one of the most humane ways to scare away geese. Unfortunately, some geese are wise to fake predators. Decoys can be more effective if you move them around frequently or purchase ones with motion features. Decoys that move in the wind are also more effective than stationary decoys.

The lifespan of a bird's nest depends on the species. The building process can take from two days to three weeks. Once built, the nesting period for baby birds can last from two to ten weeks before they leave the nest. While most young birds are ready in two to six weeks, some predatory species may need up to two and a half months. Some species nest four to five times per year, so a nest could remain in use for several months. For specific information about a particular nest's longevity, it is best to consult a wildlife professional.
