There are many manufactures of Garden Owls. [4] A swiveling head [5] and wind-powered wings [6] are features that are often used to mimic a living owls behavior, and increase the garden owl's ability to deter pests. Many technological updates to the garden owl have been made including solar motors, [7] motion sensors, [8] and hidden cameras. [9]
The largest owls are two similarly sized eagle owls; the Eurasian eagle-owl (Bubo bubo) and Blakiston's fish owl (Bubo blakistoni). The largest females of these species are 71 cm (28 in) long, have a 190 cm (75 in) wing span, and weigh 4.2 kg ( 9 + 1 ⁄ 4 lb).

A specific location may be further modified by the provision of food, the use of decoy birds, the use of calls, or owls that may induce mobbing. Male birds of some species are used as decoys during the breeding seasons to challenge and beckon other males from nearby.
Burrowing owls have bright eyes; their beaks can be dark yellow or gray depending on the subspecies. They lack ear tufts and have a flattened facial disc. The owls have prominent white eyebrows and a white "chin" patch which they expand and display during certain behaviors, such as a bobbing of the head when agitated.
Barn owls are also sometimes used as biological rodent control. [49] Although there are no quantitative studies of the effectiveness of barn owls for this purpose, [50] they are known rodent predators that can be used in addition to or instead of cats; [51] [52] they can be encouraged into an area with nest boxes.
