I'm a recent convert to "formalized" birding in general and this "forum" in particular. I'm using Merlin, Ebird, BirdNET, and Audubon for reference and identifying birds. In getting involved here on this forum, I saw a reference to "Opus." This morning I've started trying to see what Opus is, who it's for, where it is, what it is, etc. So far, I haven't found anything that will give me, a newcomer to Opus, the who, what, where, etc. of Opus. So, I'm asking if there is a thread or person, can, and will help me with this.
Thanks!
Thanks!
