I'm fairly knowledgeable about New Jersey birds, but not at all about Czech ones. I imagine the arboretum had some beauties in it. Was that in CA or NY (or other place)? I know CA has oodles of wonderful birdies.

Czech Republic has some attractive birds, but the ones I see near my house are all quite plain-looking. Plus, they piss us off that they refuse to eat the seed from our bird feeder. I tell my husband that they dislike it because it is too modern-looking (like a Frank Lloyd Wright house). Maybe they only go to places that look like European cottages . There are a few birds in CZ that I'm familiar with, but the doves make a slightly different cooing noise than the ones in New Jersey. Strange. Well, they speak a slightly different language here.

We could only view part of the cemetery today because of covid closings. In any case, what we saw was amazing and it is in a beautiful, quiet hilly area. One of the oldest Jewish cemeteries, outside of Israel, is in Prague. It's a major "must see" for anyone, but particularly people of Jewish heritage (The Wikipedia entry on it is interesting: Old Jewish Cemetery, Prague - Wikipedia).
