We saw them when we were there a month ago. The naturalists were excellent at helping identify birds. If you time it right, you might be able to ride the loop with them. We got there first thing in the morning.

Yes, there is a large variety of birds in this preserve even in February.

You can also go onto a Cornell website called ebird which will let you research what has been reported there recently. The birds are mostly aquatic species which also occur in the SE US. The truly southwestern stuff will be in other habitats.

I'd say yes because you need to sign guest book before entering. It's a small center with a few items for sale and a small learning area. Enjoy.

The seasonal birds, such as ducks, migrate through, so I guess it would all depend on the weather conditions in the U.S. at the time of your trip. There are about 8 ponds to hold swimming fowl, so there's plenty of room for many birds. I agree that you should call them and ask on average how many birds they see at the specific time you're traveling to NV. Good luck.
