Birds
Today park visitors can readily observe many birds that are active in the daytime, including raptors such as Red-tailed Hawk and American kestrel, and many insect, berry, and seed eating birds. Hummingbirds too, are active and can be observed in the daytime. Some owls, such as the Great Horned and Barn Owl, which are normally nocturnal, have been observed on occasions such as when they are breeding and have young fledglings.
