An Otter Encounter

A strange otter encounter, not once but twice, resulted in a Curious North question for the Masked Biologist, who talks about the North American river otter in this week’s Wildlife Matters. Today I have the pleasure of responding to an interesting inquiry that came in through Curious North here on WXPR. The listener wrote: “Twice this week I've heard really loud strident calls that sound almost but not quite like a raptor. Best described as chirping, but loud. Once near the Davenport street Wisconsin river bridge, the other by the Boyce drive bridge over the Pelican. The calls were echoing, as if under the bridge. I followed the sound with my binocular and eventually discovered River Otters! 2 each time. They seemed to enjoy the amplification and reverberation provided by the bridge. Here's my question. What are otters up to in mid-late March? What's the chirping all about? What type of den do otters use? What's their typical life cycle?“ What a great topic this is! I find river otters
