Sunday Showcase: Long-eared Owls

Long-eared Owls are fairly common in the Calgary area and breed in and around the city, but they are nocturnal and so secretive that many birders go years between sightings. In early summer I was told of a Long-eared Owl nest in the city with young in the nest. Here are some photos of this family taken by several local birders.

(Note: The birds are secretive since they are vulnerable to predation from Great Horned Owls, magpies, ravens, crows, porcupines, and hawks. It is very important when observing them to not give away the location of the nest. This nest was very close to a public pathway.  Although the young have fledged long ago now, the owls may nest in the same area again next year, so I won’t reveal the location. I did share it with Dan Arndt, Andrew Hart, and a couple of young birders who had never seen this species before, but we didn’t want to put undue stress on the birds or draw attention to the location by having too many people go to see them.)

June 11, 2016. Only one young remained in the nest. We were concerned that they had been predated, so stopped visiting for a while. But later on we saw two fledged young together near the nest, so they may just have fledged at slightly different times. Photo by Dan Arndt.

On June 26 Andrew Hart and I went to see if the last of the owls had fledged. The nest was empty, but we found two very vocal and active young owls nearby.

Tony LePrieur had found this same nest independently and visited it a couple of times.

Wednesday Wings: Long-eared Owl

In early April Bruce Brummitt spotted this Long-eared Owl near his home in NW Calgary. These elusive owls are resident in the Calgary area, but this one may have just been passing through. It was seen for a few days but has not been seen since April 4.

The owl was only seen at dusk, in low light. Some of the photos were taken with a flash, so the owl’s iris looks red in those shots. All photos by Bruce Brummitt.
