Everybody loves owls, no? Yes! They are particularly endearing and, with their round heads, round bodies and big eyes, they almost look like Bobblehead Toys. The problem is we need to go out at night to see them or have a spectacular bit of luck on a daytime bird walk.

Mottled Owls are the most commonly heard of them all in San Vito. You can often hear them start to call at dusk or later into the night and they sound a little bit like dogs in the distance until you accustom yourself to their voice. They start breeding in February and, when two of them get each other wound up — calling back and forth — it makes a big, kind-of-scary, duetting racket!

Apparently there is a question on the correct scientific name of this owl. According to the Taxonomy Seer of the SVBC Jo Davidson, in Costa Rica we use Ciccaba virgata. You will see it referred to as Strix virgata in the links below. In either case, or both, Mottled Owls are found from Mexico to Ecuador, Bolivia and Argentina.

The larger Black-and-white Owl is far less common but has been reliably seen and heard near the forested area around the Las Cruces Biological Station. It takes bigger prey than its cousin, feeding on small rodents and bats in addition to large insects favored by both.

You won’t be surprised to learn these owls are in the same genus with their similarly rounded shape, no ear tufts and prominent, fancy eyebrows. Ciccaba nigrolineata is the Black-and-white found from Mexico to Venezuela and Peru.

Let’s see what they have to say for themselves when asked about swiveling their heads around to nearly 180 degrees: is it fun? It looks like a conjuring trick! Click the link here and press play to hear the Mottled Owl’s reply. It sounds like it is saying, “Wow, wow, wow!” And the Black-and-white had this to say: click and press play. This sounds like “Just who are YOU?” to us.

And finally here are both of them arguing over the answer; see if you can tell who is calling by clicking here!
