Thanks for the comments ... and no .. these Sora were not lifers. The TOS field trip provided my first views of the Sora. However ... I didn't find these in the same location we saw them on the field trip. I couldn't really get to that place. TOS had access I won't have until they reopen the entire unit. So ... maybe these were the same birds we saw or maybe there are more birds than I would have imagined.
Been going out there for several years now and never thought about seeing a Sora ... but I know that they are there now... and hopefully will be able to contiune to find them. They are fun birds to watch.
The Virginia Rail was fun as well ... never got more than a peek at the bird .. really a fast bird .. in the blink of an eye .. he can move from one location to the other and so fast you wonder if he was in the second place the whole time!
