Based on field observations, naturalist Bruce Thompson believes 42 avian species nest and breed in Larch Sanctuary. His research as well as that of other scientists suggests over 90 types of birds frequent the area.
The most commonly observed are Black-capped Chickadees, American Robins, House Wrens, and Red-eyed Vireos.
Yellow Warblers, Mallards, American Crows, Chipping Sparrows, White-throated Sparrows, Brown-headed Cowbirds, Yellow-Rumped Warblers and Cedar Waxwings are the next most commonly-sighted.
The Sanctuary is home to a number of cavity-nesting birds. They are attracted by the holes created by the many woodpeckers in the area, together with other welcoming features.
Thompson observed two kinds of raptors: Swainson’s and Red-tailed Hawks. He did not locate a nest site, although the Red-tails did exhibit some territorial behaviour.
The diversity of Sanctuary habitats provides for a place for waterfowl in both flowing and still water. Common Mergansers, Common Goldeneye, Bufflehead and even Mallard, Gadwall, and Teal have been spotted breeding and brood-rearing.
Finally, two species of owls frequent the Oxbow: Northern Saw-whet and Long-eared. Another observer noted of a pair of Barred Owls as well as a nesting pair of Great Horned Owls.
