Long-eared Owls, sometimes wintering on the Chico, are vole specialists. Although they nest and roost in dense habitats, they hunt in open areas. Under a big roost it is possible to find hundreds of owl pellets, reguritated remains of dinner. Long-eared Owls breed in the northern U.S., Canada, and Eurasia north to 65 degrees. There is one record of a pair of Long-eared Owls nesting on the Chico. Roosts can be as small as two individuals and as large as …

The small, long-legged owl with white eyebrows and bright yellow eyes who lives in ground burrows is called Burrowing Owl. Unlike the resident owls in the southern parts of their range, Chico’s Burrowing Owls are migratory. They are also found in northern and in southern South American grasslands where they are resident and non-migratory. On Chico and in other areas of eastern Colorado, Burrowing Owls can be found from late March into fall in abandoned prairie-dog burrows (photo). They are …

Although Barn Owls nest upon the rafters of old barns their true nest site is the open cavity in large trees, usually where a limb has broken off. Barn Owls are in a different family than the true owls with longer legs and serrated middle toes. In the world there are 11 species, only one species in North America. They are one of the most abundant owl species in the world but because they hunt only at night they are …

While I was driving out in the sand, a normally nocturnal Short-eared Owl was observed flying in the middle of the day. Perhaps a coyote flushed this ground roosting species. As the owl flew west, I saw a wintering Chico Prairie Falcon flying towards the unsuspecting owl. The resulting encounter brought both species inches away from each other and both birds raised their talons in defense. The owl was quite vocal, hissing at the falcon. When the falcon and the …

Prior to Saturday there had been zero Northern Saw-whet Owls banded on the Chico and only two had been seen. But, on Saturday Laura-Marie caught and banded Chico’s first and then today, Monday, she caught Chico’s second (and two days later a third was caught). Here volunteer banding assistant, Dr. Anna Joy gets to release the bird before she had to leave to teach anatomy/physiology to a bunch of college students.
Called Saw-whet because one of its calls resembles the sound …

In the U.S. the best known owl is Barn Owl, probably because of its heart-shaped face and they can often be found nesting in old barns with a large opening. They are not considered a true owl, like the other Chico owls, taxonomically different in having the inner toe the same length as the middle toe, a character found in 16 other owls in the genus Tyto in the world. Barn Owls are nocturnal, hunting in open grasslands but they roost or …

In December, Great Horned Owls, the most common owl on the Chico, are already paired and both males and females are calling, their distinctive low hoots heard throughout the nighttime. By February, females are incubating eggs, sitting on nests, this one in a stick nest, others found in the cavities of large cottonwoods. By early May, young owls are almost full grown and poking their heads out of cavity nests, or falling out of stick nests as the siblings fight …

I am a serious collector of hobbies. I have interests in art, nature, community building, ecology, and horseback riding. I’m also what you could call a joiner. If there’s a group of folks out there doing work or hosting activities surrounding one of my interests and I happen to get invited, I always say yes.
That’s how I ended up meeting the ranch’s resident birder, Bill Maynard. He maintains the Birding Blog for this site. I heard Bill needed some field …

A Great Horned Owl nestling poked its head out of a tree cavity for the first time on May 3rd. Always popular with school groups and protected from potential predators by the tree nest.

The deer skull nest is one of the many surprises I come across on the ranch. It’s been there for a long time and the crew and guests see it everyday as it is located right next door to our saddlehouse. The same birds probably return each year and build it back up. The placement is perfect and gives the deer character and a little bit of a hair style.
Another little surprise – After being away for a month and arriving …
