No, but I can't say I tried very hard. I checked two spots where I have found coops before with no luck but didn't exactly scour the landscape.
Have recently become overwhelmed at work with Whooping Crane eggs coming in from abandoned nests in the reintroduced population nesting in Wisconsin and am now thinking I won't have time to do this right. That's the problem with being a bird-breeder for a living...all the action at work happens right when I'd be needing time to raise an eyass hawk. Might just stick with passage birds!
