Animals at Ascot Hills Park

The common wildlife species observed today in Ascot Hills Park are but a small fraction of those that were here before the impacts of human induced habitat changes.

Historically, the Ascot Hills may have been home to large terrestrial animals such as Black and Grizzly bear, deer and cougar. Most have been lost to hunting and fragmentation of habitat. Only occasionally in our modern times do we hear of a vagrant deer or cougar that may have strayed from the local undeveloped mountains that still host remnant populations.

Avian species including birds and insects may have been here in greater numbers, but today, the park still provides food and home to many species.

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 Great Horned and Barn owl which are normally nocturnal have been observed on occasions such as when they are breeding and have young fledglings,

A list of commonly observed terrestrial animals is included below:

[Note: We should provide a brief list here, with a disclaimer that the list is only a sampling of the actual animal species that may be found in the park.]


There has been no official survey of the amphibians in the park, however with the development of the pond and the small reach of the perennial stream, some amphibians are thought to exist here.

  • Bull frogs (an introduced predatory amphibian) have been heard near the pond;



Ascot Hills provides habitat for numerous species of birds. Many are residents breeding at the park, some are migrants or occasional visitors.

The Ascot Hills Park Advisory Board, with aid of local birders, Pedro Ramirez, and PAB member, Cindy Castañeda, conducted quarterly bird counts from March 2018 – February 2020. Fifty four species were observed. (For a listing of Species Observed, CLICK HERE)
