Hi Suzanne!
This is a new feature that eBird has just rolled out in the past few weeks - Hotspot Groups! In order to consolidate data from locations with many sub-hotspots (consider Cherry Creek State Park or Rocky Mountain NP with their innumerable birding spots), individual hotspots can now be designated as part of a group, and data for the whole group is then viewable on the group hotspot. The CO hotspot editing team has decided that, for now, we're trying to keep hotspot groups to single counties. Therefore, both the Chico Basin Ranch (El Paso Co.) and Chico Basin Ranch (Pueblo Co.) hotspots are now parent hotspots for all of the locations at Chico Basin in El Paso and Pueblo Counties, respectively. Importantly, your checklists always remain linked to the hotspot you used to submit them - your Wooded Areas list will be visible on the parent hotspot, but eBird knows it's only one list, and that it came from the Wooded Areas. We hope this incentivizes users to select the most precise hotspot possible, since data will be aggregated on the user end within the group hotspot. If you notice an issue with a hotspot group, or have an idea for one that doesn't yet exist, you can always leave a comment for a local hotspot editor by going to the "About" tab on an appropriate hotspot, clicking "Suggest Content", and writing your feedback in the "Notes to the Editor" box at the bottom.
Best,
