I was on a walk with some experienced birders a year or so ago and they were talking about the cat collars they have seen high up in trees. I was shocked that great horned owls can take cats like that.
And wallabies?! Yikes!!!
Last year I went on a guided program to spot short-eared owls. This fall I went to various locations near my home to find Northern Harriers since I know they like the same habitat as the owls. Three weeks ago I saw my first, "I found it no one showed me," owl. I also have seen a Barred Owl that is a bit of a celebrity because he likes to hang out during the day where people can see him from a boardwalk in the Great Swamp. And I was fortunate to attend an owl banding session for Northern Saw-Whet owls. All of this was in Central NJ.
